Referring to FIG. 5 , a flowchart of steps in Embodiment 5 of an offline file transmission method of the present invention is shown. In this embodiment of the present invention, the first terminal device is a sender of target file resources, and the second The terminal device is the recipient of the target file resource, and the first terminal device and/or the second terminal device may be a mobile device or a computing device, wherein the computing device is a Intelligent electronic devices that process massive amounts of data, such as desktop computers, laptops, etc. The mobile device is a computing device that can be used in movement, such as a mobile phone, and there is no need to limit the types of the first terminal device and the second terminal device in this embodiment of the present invention.

This embodiment of the present invention may include the following steps:

Step 501, obtaining a corresponding target file resource on the side of the first terminal device according to a file resource selection instruction issued by a user;

In a preferred embodiment of the present invention, the file resource selection instruction may be a download instruction for a certain file resource selected by the user in the file resource download list displayed on the side of the first terminal device. Specifically, a first client program is installed on the side of the first terminal device, and a large number of free file resources are displayed in the first client program for the user to download, and the user can download the file resources from the first client program Choose your favorite file resource to download. In practice, after the user selects his favorite file resource from the download list of file resources displayed by the first client program through a mouse or touch operation, the corresponding file resource download instruction is generated, and the first client program receives After the file resource download instruction is received, the corresponding file resource is downloaded from the server as a target file resource and stored on the side of the first terminal device.

In practice, the first client program opens a floating window on the computer side for the transmission of target file resources. When the user opens the first client program on the first terminal device side, the first client program can be suspended in the floating window. A pop-up window pops up in the window or at the preset position of the first terminal device to remind the user that offline file resources can be sent to the second terminal device, that is, the first terminal device can send file resources at any time without connecting to the second terminal device (as shown in Figure 6). shown).

Specifically, the function of the floating window is that when the window of the main program is minimized, it can also prompt the user to see the running status of the program, and can quickly open the window of the main program by clicking on these small windows. The floating window includes a preset entry that can be accessed by the user. After the floating window is displayed on the screen, the user can access preset content or perform preset operations through the preset entry. For example, the user can start the operation of sending the file by clicking on the preset entry.

In another preferred embodiment of the present invention, the file resource selection instruction may be a selection instruction for a certain file resource selected by the user from the file resources stored on the side of the first terminal device. Specifically, the user may also select a certain file resource from the existing file resources stored on the side of the first terminal as the target file resource.

As a preferred example of this embodiment, the target file resource has file attribute information, and the file attribute information may include the size of the target file resource, the type of the target file resource, the version number of the target file resource, the logo, etc. Wherein, the types of the target file resources may include themes, wallpapers, ringtones, software, music, games, videos, e-books, and other types.

Step 502, when the first terminal device does not detect the access of the second terminal device, send the target file resource to the file server through the floating window on the side of the first terminal device;

Specifically, after the first terminal device side acquires the target file resource, the first terminal device uses the first client program to detect whether there is access by the second terminal device, and in the case of no access by the second terminal device , the first client program detects whether the user initiates a specified operation on the floating window. Wherein, the designated operation initiated for the floating window may be in various ways. Referring to the schematic diagram of the designated operation of the floating window shown in FIG. 7 , as a preferred example of this embodiment, the designated operation initiated by the user for the floating window may be: It includes the operation of dragging the target file resource to the floating window by the user, that is, the operation of directly dragging the target file resource into the floating window after the user selects the target file resource from the file resources stored on the side of the first terminal. As another preferred example of this embodiment, the specified operation initiated by the user on the floating window may include that the user clicks a file selection button on the floating window, and selects the target file resource in the file path selection window popped up by the first terminal device For example, the file selection button can be the function button of "select the file to be sent" shown in Figure 7. After clicking the file selection button, a file path selection window will pop up on the side of the first terminal device, The user can select the path of the target file resource in the file path selection window.

When the first client program detects that the user initiates a specified operation on the floating window, the first client program can send a reminder message to ask the user whether the target file resource needs to be sent offline. Or a pop-up window pops up at a preset position of the first terminal device to be displayed to the user, and after receiving the offline confirmation instruction selected by the user, the target file resource is sent offline. The offline confirmation instruction is an instruction instructed by the user to confirm that the target file resource is sent offline. The offline confirmation instruction may be embodied as an instruction triggered by the user clicking a "confirm sending offline file" and other similar function buttons in the pop-up window.

On the other hand, if the user indicates that the target file resource does not need to be sent offline, the user can click the "Do not send offline file" and other similar function buttons in the pop-up window to trigger the instruction not to send the offline file. At this time, the target file resource is in the Waiting to send in the above floating window.

In practical applications, there are many ways for users to trigger an offline confirmation instruction or an instruction not to send offline files, except for the above-mentioned clicks of “Confirm to send offline files”, “Do not send offline files” and other similar function buttons to achieve the goal In addition to whether the offline sending of the file resource is triggered, if a gravity sensing device is installed in the first terminal device, the gravity sensing device can also be triggered by shaking the first terminal device, thereby realizing the offline sending of the target file resource. trigger. In the embodiment of the present invention, the shaking can be understood as any operation that can trigger the gravity sensing device, such as shaking the mobile device up and down or left and right, and the embodiment of the present invention does not limit the specific operation.

In a preferred embodiment of the present invention, after receiving the offline confirmation instruction sent by the user, step 502 may further be: generating a file sending request on the side of the first terminal device according to the user's designated operation for the floating window; The first terminal device side sends the file sending request to the file server; the first terminal device side receives the file response message returned by the file server; the first terminal device side sends the target The file resource is sent to the file server. Specifically, the file sending request may include the size of the target file resource. After receiving the file sending request, the file server determines whether its own memory size is larger than the size of the target file resource according to the size of the target file resource. , if it is greater than , the file server returns a file response message to notify the first terminal device to upload the target file resource; otherwise, the file server does not return a file response message. If the first terminal device receives the file response message within the preset time period, it will send the target file resource to the file server according to the file response message; if the first terminal device does not receive the file response message within the preset time period When the file response message is received, the target file resource is not sent to the file server, and at this time, the target file resource is in a waiting state in the floating window.

In practice, in order to ensure the security of the target file resource, before uploading the target file resource, the first client program may encrypt the target file resource according to the first preset rule before uploading it to the file server. The first preset rule may be an encryption and decryption rule pre-agreed by the first client program and the background server.

Step 503, the file server generates the download address of the target file resource and returns it to the first terminal device side;

Specifically, the file server is a server for sharing files and is used for storing target file resources. In practical applications, the file server only saves the target file resources within a preset time period, and the file server may periodically or irregularly detect the stored target file resources. If the time exceeds the preset time period, the target file resource is deleted. Wherein, the preset time period may be the time period set as the start time for the storage time of each target file resource (for example, one month, the target file resource exceeding the storage time for one month will be deleted); The preset time may also be a time limit uniformly set by the file server for all stored file resources (for example, the target file resources stored before July 10, 2013 will be deleted).

After receiving the target file resource, the file server obtains the storage address of the target file resource on the file server side, and generates the download address of the target file resource from the storage address according to the second preset rule. The download address is encrypted according to the first preset rule and returned to the first terminal device side.

In a specific implementation, the user can select one or more target file resources and send them through the floating window. At this time, the first terminal device can use the first client program to generate a file sending list, and the file sending The list is a list of target file resources to be sent offline through the floating window, and the first terminal side displays the file sending list at a preset position of the floating window or other preset positions on the interface of the first terminal device. The file sending list has file sending status information for each target file resource, and the file sending status information may include successful sending status, sending status, waiting for sending status, and sending failure status. Wherein, the file sending status information refers to the status information of the file being sent to the file server, the successful sending status is the status of receiving the corresponding download address returned by the file server within a preset time period; the sending failure status is The status of the corresponding download address returned by the file server is not received within the preset time period.

In practical applications, viewing guide information may also be displayed in the file status list, where the viewing guide information is used to instruct the user how to receive and view offline file resources in the second terminal device.

Step 504, constructing the download address of the target file resource and the information package of the file attribute information on the side of the first terminal device and sending them to the application server;

Applied to the embodiment of the present invention, after receiving the download address of the target file resource returned by the file server by using the first client program, the first terminal device side decrypts the download address of the target file resource according to the first preset rule, and then decrypts the download address of the target file resource. The download address of the target file resource and the information package of the file attribute information are constructed, and the information package is encrypted using the first preset rule and sent to the application server.

It should be noted that the information package is actually a data structure in which the download address of the target file resource and the file attribute information are recorded.

Step 505, the application server obtains the identifier of the first terminal device, and searches the preset association relationship list for the identifier of the second terminal device that has an associated relationship with the identifier of the first terminal device;

Specifically, the preset association relationship list stores the association relationship between the identifier of the first terminal device that has been connected and the identifier of the second terminal device. The process of generating the association relationship may be (taking the first terminal device as a computing device and the second terminal device as a mobile device as an example):

First, the computing device receives the notification message for establishing a long connection sent by the mobile device, and the notification message includes the identifier of the mobile device; if the computing device allows the establishment of a long connection, the computing device sends the identifier of the mobile device and the identifier of the computing device to the application server, The association relationship between the mobile device and the computing device is recorded by the application server in the association relationship list.

Specifically, establishing an association relationship between a mobile device and a computing device mainly includes the following steps:

1. The mobile device is authenticated on the application server;

1.1 Start the second client program (ie, mobile phone assistant) on the mobile device;

1.2 After entering the mobile phone number on the mobile device, the mobile device sends the IMEI and mobile phone number of the device to the application server;

1.3 The application server sends a text message with an authentication code to the mobile device;

1.4 Enter the authentication code on the mobile device and send it to the application server;

1.5 The application server determines that the identity of the mobile device is owned by the mobile device according to the authentication code, the mobile device number and the IMEI.

2. At the computing device

2.1 Start the mobile assistant on the computing device;

2.2 After entering the mobile phone number of the mobile device, the computing device sends the mobile phone number and MID of the mobile device to the application server;

2.3 The application server inquires in the database whether the mobile device corresponding to the mobile phone number has been authenticated at the application server according to the received MID and mobile phone number of the computing device, and if authenticated, establishes the computing device in the association list The corresponding relationship between the MID, mobile phone number, and IMEI of the mobile device, for example, store them as a record in the association list; otherwise, send an invitation to the mobile device, and the invitation process is as follows:

2.3.1 The application server sends an invitation text message to the mobile device, and the invitation text message contains an activation link address;

2.3.2 When the mobile device receives the short message, a binding permission dialog box will pop up. After the user clicks OK, the information in the activation link will be sent to the application server. After receiving the binding confirmation request, the application server will The mobile device is bound to the corresponding computing device.

The relationship list structure is

The database table for messages is:

Specifically, the identification of the mobile device is mobile1, and the identification of the computing device is desktop1. When the mobile device is to be associated with the computing device, the long connection sends the association request to the computing device. After the computing device agrees to confirm, the association mobile1<- ->desktop1 is established. After the application server receives the information packet, the application server also records the mapping relationship of desktop1<-->information packet file1. After receiving the information packet, the application server decrypts it, obtains the identifier of the first terminal device, and then searches the preset association relationship list for a second terminal device associated with the identifier of the first terminal device. The identification of the terminal device. In practical applications, the association relationship between the identifier of the first terminal device and the identifier of the second terminal device in the preset association relationship list is as follows:

(1) The identifier of the first terminal device only corresponds to the identifier of one second terminal device. In this case, the application server selects the identifier of the second terminal device as the recipient of the target file resource.

(2) The identifier of the first terminal device corresponds to the identifiers of multiple second terminal devices. In this case, since in practice, the preset association relationship list can also store the latest connection time between the identifier of the first terminal device and the identifier of each second terminal device, at this time, the application server can According to the latest connection time between the identifier of the first terminal device and the identifier of each second terminal device, select the identifier of the second terminal device connected recently (that is, the last second terminal connected to the first terminal device). device) as the recipient of the target file resource.

After the application server obtains the identifier of the second terminal device that is the recipient of the target file resource, it generates an information confirmation instruction, and sends the information confirmation instruction to the first terminal device through a push server (push server), and the information confirmation The instruction includes the identifier of the second terminal device, and the information confirmation instruction is used to inform the first terminal device to confirm whether to send the target file resource to the identifier of the selected second terminal device. As shown in the schematic diagram of offline reminder shown in FIG. 8 , after receiving the information confirmation instruction, the first terminal device can use the first client program to display the identifier of the second device to which the target file resource is to be sent in the form of a pop-up window or the like It is displayed to the user, if the user selects "send immediately", indicating that the user confirms that the target file resource is sent to the identifier of the second terminal device, the first terminal device side generates first confirmation information and sends it to the application server side. In addition, if the user's intention is not to send the target file resource to the identifier of the second terminal device, the user can select a button with words such as "channel changing device", and the first terminal device side generates a second confirmation message to send To the application server, at this time, the user can connect the second terminal device that needs to receive the target file resource to the first terminal device to receive the target file resource; if the user does not access any second terminal device, the application server Find out whether there are other identifiers of the second terminal equipment associated with the identifiers of the first terminal equipment in the preset association relationship list, and if so, obtain the identification generation information of the second most recently connected second terminal equipment to confirm The instruction is sent to the first terminal device side, and so on; otherwise, the application server generates a connection reminder message and sends it to the first terminal device side to notify the user to connect to the second terminal device that needs to accept the target file resource.

Step 506, generating a file acquisition message on the application server side according to the identifier of the second terminal device and sending it to the push server;

After receiving the first confirmation information sent by the first terminal device, the application server generates a file acquisition message according to the identifier of the second terminal device, and sends the file acquisition message to a push server (push server). The file obtaining message is used to notify the push server to send the file obtaining message to the second terminal device when detecting that the second terminal device corresponding to the identifier of the second terminal device is online, so as to notify the The second terminal device obtains the information package from the application server.

Step 507, when the push server side detects that the second terminal device corresponding to the identifier of the second terminal device is online, it sends the file acquisition message to the second terminal device side;

In practice, the push server is used to push the file acquisition message to the corresponding second terminal device. Specifically, after receiving the file acquisition message, the push server acquires the identifier of the second terminal device carried in the file acquisition message, and displays the identifiers of all connected terminal devices (the terminal device will Automatically connect to the push server) to search for a terminal device with the same identification as the second terminal device, if the search is successful, it means that the second terminal device is online, otherwise, it means that the second terminal device is not online.

When detecting that the second terminal device is online, the push server directly sends the file acquisition message to the second terminal device; if it detects that the second terminal device is not online (ie, offline), wait until The second terminal device sends the file acquisition message to the second terminal device online.

In a specific implementation, whether the second terminal device is online or not is determined according to the network state obtained by monitoring. Specifically, in a preferred embodiment of the present invention, if the second terminal device is a mobile device with an Android system installed, it monitors the network status as follows:

The network status is a SystemService, which can be obtained through context.getSystemService(Stringname). When the network status changes, SystemServic will send out android.net.conn.CONNECTIVITY_CHANGE broadcast. At this time, the mobile device side only needs to register a service (service), You can receive the broadcast of network status changes in the background. This service can be ConnctionChangeReceiver; to process the received broadcast, the implementation method is as follows. Add network status judgment in onReceive:

ConnectivityManager connectMgr=(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo mobNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

NetworkInfo wifiNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

Among them, ConnectivityManager is to obtain the current system service information;

getNetworkInfo obtains the information of the two networking methods of MOBILE and WIFI respectively;

The current networking status is determined by judging the Boolean values returned by mobNetInfo.isConnected() and wifiNetInfo.isConnected(). If the returned Boolean value is true (or 1), it means that the current network is available and the mobile device can be connected; if it returns The boolean value of is false (or 0), which means that the current network is unavailable and the mobile device cannot connect.

In another preferred embodiment of the present invention, if the second terminal device is a computing device, it monitors the network status as follows: if the computing device needs to wirelessly connect to the network, it can call the network interface API to obtain the current network status , if the current network status is available, the computing device is connected to the current network, otherwise, it is not connected to the current network.

Step 508, on the second terminal device side, obtain the corresponding information package from the application server according to the file obtaining message;

Specifically, a second client program is installed on the side of the second terminal device, and the second terminal device adopts the second client program to receive the file acquisition message sent by the push server, and when receiving the file acquisition message , the file acquisition message can be displayed in the preset display position of the second terminal, and the user is notified that there are offline file resources in the form of a prompt tone or a pop-up window. After the user clicks the file acquisition message, the second terminal is prompted to The device uses the second client program to obtain the information package from the application server.

Step 509, on the second terminal device side, download the corresponding target file resource from the file server according to the download address of the target file resource.

After acquiring the information package, the second client program decrypts the information package, obtains the download address of the file resource in the information package, and obtains the corresponding target file resource from the file server according to the download address of the file resource.

Further, after the second client program decrypts the information package, it can also obtain the type of the target file resource, and perform the following operations according to the type of the target file resource: if the type of the target file resource is the subject, wallpaper, ringtone, music, video, e-book, etc., the target file resource is stored on the second terminal device side; if the target file resource is an installation type such as software and/or games, directly install all Describe the target file resource. After storing the file resources or installing the file resources, the second client program can notify the user of the installed file resources or the stored file resources in the form of a notification message or a pop-up window at the preset display position of the interface of the second terminal device The file information, wherein the file information can be presented in the form of a list.

In this embodiment of the present invention, the first terminal device and the second terminal device may not be online at the same time when transferring file resources, that is, the first terminal device first uploads the target file resource to the background server when it is online. The second terminal device does not necessarily need to be online, and when the second terminal device is online, the target file resource is downloaded from the background server, thereby reducing restrictions on file resource transmission and improving user experience.
