detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , it shows a flow chart of the steps of Embodiment 1 of a method for cleaning data on a server according to an embodiment of the present invention, which may specifically include the following steps:

Step 101, when it is determined that the startup operation of the currently started router is a restart operation after restoring factory settings, a data cleaning instruction is generated, and the data cleaning instruction includes a router identification;

Step 102, sending the data cleaning instruction to the cloud server;

Wherein, the data cleaning instruction is used to prompt the cloud server to search for the account binding relationship corresponding to the router identifier in the pre-stored account binding relationship, and delete the account binding relationship when the corresponding account binding relationship is found. The corresponding account binding relationship, and generating response information and returning the response information to the router, wherein the account binding relationship is a binding relationship between the router identifier and the user's login account information.

In the embodiment of the present invention, when it is determined that the startup operation of the router is a restart operation after restoring factory settings, a data cleaning command is generated and sent to the cloud server to request the cloud server to delete the account binding relationship corresponding to the router ID of the router , to ensure the successful deletion of the account binding relationship, and to ensure that the information stored in the router is consistent with the information stored in the cloud server after the router is restored to factory settings.

Referring to FIG. 2 , it shows a flow chart of steps in Embodiment 2 of a method for cleaning data on a server according to an embodiment of the present invention, which may specifically include the following steps:

Step 201, if it is detected that the current router is started, start a preset service program;

Applied to the embodiment of the present invention, a dedicated service program may be set in the router, and the service program is started when the router is started.

In a specific implementation, after the service program completes the initialization operation, it can become a daemon process of the router. Wherein, the daemon process is also the Daemon process, which is a background service process in Linux. It is a process with a long life span, usually Daemons are often started when a device is bootloaded, independently of the controlling terminal and periodically perform some task or wait for some event to occur.

Step 202, using the service program to judge whether the startup operation is a restart operation after restoring factory settings; if so, then perform step 203, if not, then perform step 208;

After the service program is started, the service program can be used to perform data communication with the cloud server, so as to request the cloud server to complete operations such as data cleaning related to the router.

First of all, the service program can judge whether the startup operation of the router is a restart operation after restoring the factory settings. Among them, restoring the factory settings refers to restoring the individual settings of the device or instrument to the factory default state, such as the start interface, standby mode, and quick operation. Keys, timing reminders, etc. are restored to factory settings.

In a preferred embodiment of the embodiment of the present invention, step 202 may further be:

Adopt described service program to judge whether there is token token information in the preset configuration file; If so, then judge that described start-up operation is not the restart operation after restoring factory settings; If not, then judge that described start-up operation is to restore factory settings subsequent restart operation.

It should be noted that the router in the embodiment of the present invention is implemented based on the OpenWrt framework. When the user logs in the account information, the router can obtain the corresponding token token information and save it in the configuration file. If the router restores the factory settings, the token information in the configuration file will be cleared.

Therefore, by judging whether there is token information in the configuration file, you can judge whether the router’s startup operation is a restart operation after restoring factory settings. If there is token information in the configuration file, it means that the configuration file has not been cleared, which further indicates that the router has not performed recovery. Factory settings; otherwise, if there is no token information in the configuration file, it means that the configuration file is cleared, further indicating that the router has performed a factory reset.

Step 203, using the service program to generate a data cleaning instruction;

If the service program determines that the current router startup operation is a restart operation after restoring the factory settings, at this time, the service program can obtain the hardware information of the router, such as the router ID, and generate a data cleaning command based on the router ID. The data cleaning command It can be used to request the cloud server to delete data related to the router in the cloud server, for example, delete the account binding relationship between the router identifier and the user's login account information.

As an example, the router identifier may include one or more of the following identification information: SN (Serial Number, device serial number) code of the router, key tag mac_key of the router, device ID of the router, and the like.

Step 204, using the service program to send the data cleaning instruction to the cloud server;

After the service program generates the data cleaning command, it can send the data cleaning command carrying the router ID to the cloud server, so as to prompt the cloud server to complete the following operations: Find the account corresponding to the router ID in the pre-stored account binding relationship binding relationship, and delete the corresponding account binding relationship when the corresponding account binding relationship is found, and generate response information and return the response information to the service program.

Specifically, on the cloud server side, it stores the hardware information of the router in the database, including the router ID, etc., and saves the account binding relationship between the router ID and the user's login account information. After receiving the data cleaning instruction, the cloud server matches the router identifier carried by the data cleaning instruction in the database, and returns a response message according to the matching result.

Specifically, if the cloud server can match the router ID in the database, it can obtain the account binding relationship corresponding to the router ID, and delete the account binding relationship to ensure consistency with the router information. After that, the cloud server can generate a successful response message and return the successful response message to the service program.

If the cloud server does not find the router ID in the database, it means that the router ID does not exist, that is, there is no account binding relationship corresponding to the router ID in the cloud server. This may occur because the user does not have a login account at all. , then there will be no token information in the configuration file of the router, so the cloud server does not have an account binding relationship corresponding to the router identifier, and the cloud server can generate a failure response message at this time. It should be noted that there may be many reasons for the cloud server to generate the failure response information, therefore, different error codes can be used to indicate the failure response information caused by different reasons, that is, the failure response information generated by the cloud server does not have an account binding relationship. The failure response information can be expressed by an error code reflecting that the binding relationship does not exist.

In addition to the above-mentioned failure response information caused by the absence of the account binding relationship, there may also be other factors that cause the cloud server to generate a failure response information. If the above account binding relationship fails, a failure response message will also be generated at this time. In the embodiment of the present invention, the failure response information generated due to the failure to delete the account binding relationship is referred to as failure response information of preset rules.

Step 205, judging whether the response information returned by the cloud server is received within the first time period; if yes, then perform step 206; if not, then perform step 207;

After the service program sends the data cleaning instruction to the cloud server, it has been waiting for the response information returned by the cloud server. In order to prevent the service program from being in a dead state, the embodiment of the present invention sets the waiting time as the first time period, and judges that the service program is in the first time period. Whether to receive the response information returned by the cloud server within the time period.

In a specific implementation, the situation that the service program does not receive the response information returned by the cloud server within the first time period includes but is not limited to the following two situations:

The first situation is that due to network failure or disconnection of the network connection, the data cleaning command sent by the service program is not successfully sent to the cloud server, so the cloud server will not receive the data cleaning command and make corresponding actions. In this case, the service program will not receive the response information returned by the cloud server within the first period of time.

Another situation is that the service program can successfully send the data cleaning command to the cloud server, and the cloud server can also make corresponding processing, generate a response message and return it, but in the process of returning the response message, due to network failure, or the network The service program cannot receive the response information returned by the cloud server within the first time period due to the disconnection of the connection.

Step 206: judging whether the response information is failure response information of a preset rule; if yes, perform step 207, if not, perform sub-step 208;

Step 207: Send the data cleaning instruction to the cloud server again at intervals of a second preset time period, and return to step 205;

Step 208: Exit the service program.

If the service program can receive the response information returned by the cloud server within the first period of time, the service program further judges the type of the response information. If the response information is a successful response information, it means that the cloud server has successfully deleted the account binding relationship. When the task of the service program is completed, the service program can be exited.

If the response information is failure response information that the account binding relationship does not exist, it means that the account binding relationship does not exist in the cloud server, and the task of the service program is completed at this time, and the service program can be exited.

If the response information is the failure response information of the preset rules, it means that the cloud server cannot successfully delete the account binding relationship temporarily due to network failure or database failure. Even repeatedly send data cleaning instructions to the cloud server until the cloud server successfully deletes the account binding relationship.

When the service program needs to exit, in the specific implementation, in order to save the storage resources and data processing resources of the router and improve the data processing efficiency, the service program can first release the occupied router resources, return the storage space, and then exit the service program, the router continue working.

In the embodiment of the present invention, a special service program is set in the router to complete operations such as the judgment of restoring factory settings and restarting operations, the generation of data cleaning instructions, the sending of data cleaning instructions, and the reception of response information, so that the service program can Focus on the above operations to improve the operational efficiency of the router.

In addition, in the embodiment of the present invention, when no response information is received or the received response information is failure response information according to preset rules, the service program is used to repeatedly send data cleaning instructions until the cloud server successfully deletes the account binding relationship, ensuring The account binding relationship in the cloud server is successfully deleted to ensure the data consistency between the router and the cloud server.
