【Detailed ways】

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

In order to facilitate the understanding of the present invention, firstly, the system architecture and main concepts involved in the present invention will be described. As shown in Figure 1, the system architecture mainly includes a host application and a server side corresponding to the host application.

The applet relies on the host application to run on the terminal device, and the environment in which the applet runs is provided by the host application. The terminal devices may include, but are not limited to, such as: smart mobile terminals, smart home devices, network devices, wearable devices, smart medical devices, PCs (personal computers), etc. Among them, smart mobile devices can include mobile phones, tablet computers, notebook computers, PDAs (personal digital assistants), Internet cars, and so on. Smart home devices may include smart home appliances, such as smart TVs, smart speakers, and so on. Network equipment may include, for example, switches, wireless APs, servers, and so on. Wearable devices may include, for example, smart watches, smart glasses, smart bracelets, virtual reality devices, augmented reality devices, mixed reality devices (that is, devices that can support virtual reality and augmented reality), and so on.

The same terminal device may contain multiple host applications. In FIG. 1, the host application 1 and the host application 2 are taken as an example. A host application may also run multiple applets, and different host applications may run different applets or the same applet. As shown in Figure 1, the host application 1 runs the applet a and the applet b, and the host application 2 runs the applet b and the applet c.

Each host application has a corresponding server side. As shown in FIG. 1, the host application 1 corresponds to the server side 1, and the host application 2 corresponds to the server side 2. Each host application can interact with its corresponding server end. In the embodiment of the present invention, data exchange can also be performed between different server ends.

Each server can be a single server or a server group composed of multiple servers. It should be understood that the numbers of terminal devices, host applications, applets, and servers in FIG. 1 are merely illustrative. According to implementation needs, there can be any number of terminal devices, host applications, applets, and servers.

The core idea of the present invention is that each host application in the same terminal device shares terminal capabilities, thereby solving the problem of integrating a large number of business function codes in a host application and saving resources. The method provided by the present invention will be described in detail below in conjunction with embodiments.

Example one,

Figure 2 is a flowchart of the method provided by Embodiment 1 of the present invention. The method is executed by the host application 1 of the terminal device. The execution device may be a plug-in or a software development kit (SDK) located in the host application of the terminal device. unit. As shown in Figure 2, the method mainly includes the following steps:

In 201, the host application 1 obtains an event for the applet to call the host application's capabilities.

During the service process of the applet, it may be necessary to call the capabilities of the host application to realize the corresponding service. The so-called end capability refers to the functions possessed by the host application, which are the functions provided by the host application as a host environment for the services of the applet, such as networking functions, payment functions, geographic location functions, album reading functions, and so on.

In 202, it is judged whether the host application 1 has the end-to-end capability for calling the applet, and if so, execute 203, and the host application 1 calls its own end-to-end capability to realize the service of the applet, and ends the current process. Otherwise, go to 204.

In 204, the local database of the host application 1 is queried to determine other host applications in the terminal device that have the ability to call the applet, suppose it is the host application 2.

In this embodiment, after the host application 1 is started, the terminal capability information of the host application installed on the terminal device may be obtained from the server side, and stored in the local database of the host application 1. Then in this step, the host application 1 can learn about the host application capable of calling the applet on the terminal device by querying the local database.

Among them, the process for the host application 1 to obtain the terminal capability information of the host application installed on the terminal device from the server is described in detail with reference to FIG. 3 and FIG. 4 respectively. However, it should be noted that the two modes shown in FIG. 3 and FIG. 4 are only the two preferred implementation modes provided by the embodiments of the present application, but are not limited to the two modes. Other ways to achieve the same effect based on the same idea are all within the protection scope of this application.

The first way is shown in Figure 3, which can include the following steps:

In 301, the host application 1 sends a first request to the server of the host application 1.

In 302, the server sends a list of host applications that belong to the same host alliance as host application 1 to host application 1.

An ideal situation is that all host applications use the same applet standard. But often in actual situations, some host applications adopt the same applet standard, but other host applications adopt other applet standards. Then the host application that adopts the same applet standard can be called a host alliance. Each host application for the same host alliance can adopt the mode of the functional end capability provided by the embodiment of the present invention. Which host applications belong to the same host alliance can be configured on the server side uniformly, and then each host application obtains it from the server side.

The host application 1 can send a first request to the corresponding server to synchronize the host alliance information when or after the host application 1 is started, and the corresponding server returns to the host application 1 a host application list of the host alliance, for example, contains the package name of each host application.

In 303, the host application 1 determines the host application information that has been installed on the terminal device in the host application list.

When or after the host application 1 is started, it can scan the locally installed applications of the terminal device, and then further use the host application list of the same host alliance obtained from the server to determine that the terminal device in the host application list has been The installed host application information can be stored in the database of the host application in the form of a list.

In 304, the host application 1 sends a second request to the server, and the second request includes information about the host application that has been installed on the terminal device in the host application list.

In 305, the server sends the terminal capability information of the host application installed on the terminal device to the host application 1.

The end capability information that can be shared by the host application can be pre-configured on the server side of each host application, where the end capability information may include the end capability name and the interface information of the end capability. The interface information of the terminal capability may include the calling method, the protocol (scheme), parameters, and so on.

In addition, the server side of each host application can provide an access interface to the server side of the same host application, and the server side of the same host alliance can synchronize the end capability information of each host application through the access interface of the server side of other host applications. The synchronization method can be periodic synchronization or synchronization triggered by a specific event.

The second way is shown in Figure 4, which can include the following steps:

In 401, the host application 1 sends a list of host applications installed on the terminal device to the server of the host application 1.

When or after the host application 1 is started, it can scan the applications installed locally on the terminal device, and upload the scanned host application list to the server.

In 402, the server determines the terminal capability information of the host application belonging to the same host alliance as the host application 1 from the host application list.

Similar to FIG. 3, the server is pre-configured with the information of the host applications belonging to the same host alliance, and the end capability information of other host applications can be synchronized with other servers belonging to the same host alliance. Therefore, the server can first determine the host applications belonging to the same host alliance as the host application 1 from the host application list in this step, and then further determine the end capability information of these host applications.

In 403, the server returns the determined terminal capability information of the host application to the host application 1.

In the manner shown in FIG. 3 or FIG. 4, the host application 1 obtains the terminal capability information of the host application installed on the terminal device from the server, and stores it in the local database of the host application 1. Then in step 204, by querying the local database of the host application 1, it is possible to determine other host applications in the terminal device that have the end capability of the applet call and their corresponding end capability information.

In 205, the terminal capabilities of the host application 2 are invoked to realize the service of the applet.

In this step, the host application 1 determines the call interface information of the end capability based on the end capability information stored in the local database, such as the interface call method, scheme, parameters, etc., so as to call the host application 2’s interface of the end capability. , And get the result of the call through the callback function (callback).

The service interface of the applet can be maintained during the above-mentioned whole calling process. It is also possible to jump to the interface of the host application 1 during the call, or further jump to the interface of the host application 2, and return to the service interface of the applet after the end of the call.

In addition, if in the above process, the host application 1 determines that no host application in the terminal device has the ability to call the applet, it can return a call failure message to the applet, or prompt the user that the call failed.

In addition, if the host application 1 fails in the process of invoking the terminal capabilities of the host application 2, it can return a call failure message to the applet, or prompt the user that the call failed. Or, you can continue to try to call the end capabilities of other host applications that have the end capabilities.

FIG. 5 is a flowchart of the method provided by Embodiment 2 of the present invention. The method is executed by the host application 1 of the terminal device. The execution device may be a plug-in located in the host application of the terminal device or a software development kit (SDK) and other functions unit. As shown in Figure 5, the method mainly includes the following steps:

Steps 501 to 503 are the same as steps 201 to 203 of the first embodiment, and will not be repeated.

In 504, the host application 1 queries the shared database in the terminal device to determine other host applications that have the ability to call the applet, assuming that it is the host application 2.

In this embodiment, each host application can store its own terminal capability information in the shared database of the terminal device. For example, each host application can store its own terminal capability information in a shared database after installation.

An ideal situation is that all host applications use the same applet standard. But often in actual situations, some host applications adopt the same applet standard, but other host applications adopt other applet standards. Then the host application that adopts the same applet standard can be called a host alliance. Each host application for the same host alliance can adopt the mode of the functional end capability provided by the embodiment of the present invention. Therefore, a preferred implementation manner is that each host application stores its own end capability information in the shared database of its own host alliance, and then the function database stores end capability information of each host application belonging to the same host alliance. In this step, the host application 1 queries the shared database corresponding to the host alliance.

The form of the aforementioned shared storage space is not limited by the present invention. For example, an SDCard may be used, or other forms of shared storage space may also be used.

In 505, the terminal capabilities of the host application 2 are invoked to realize the service of the applet.

This step is the same as step 205, and will not be described in detail.

Similarly, the service interface of the applet can be maintained during the entire invocation process. It is also possible to jump to the interface of the host application 1 during the call, or further jump to the interface of the host application 2, and return to the service interface of the applet after the end of the call.

In addition, if in the foregoing process, the host application 1 determines that no host application in the terminal device has the ability to call the applet, it can return a call failure message to the applet, or prompt the user that the call failed.

Based on the consideration of factors such as security and synchronization reliability, the implementation manner provided in the first embodiment is preferred.

Here is an example of an application:

Assume that host applications 1, 2, 3, and 4 are installed in the terminal device. After the host application 1 is started, it requests and obtains the list of host applications that belong to the same host alliance as the host application 1 from the server side of the host application 1, assuming that the host applications 1, 2, and 3 belong to the same host alliance. The host application 1 requests and obtains the end capability information of the host applications 1, 2 and 3 from the server, and stores it in the local database of the host application 1.

The content stored in the local database is assumed to be:

Host application 1-ability to pay-calling interface information of ability to pay;

Host application 2-connect to wifi function-to connect to the calling interface information of wifi function;

Host application 3-read local album function-read the calling interface information of the local album function.

In the process of using applet a on the host application 1, the user triggers an event to call the wifi connection function.

After the host application 1 obtains the above event, assuming that the host application 1 does not have the wifi connection function, then the local database is queried to determine that the host application 2 has the wifi connection function. According to the calling interface information of the connection wifi function recorded in the local database, the corresponding interface of the host application 2 is called and related parameters are passed. The call result is returned to the host application 1 through callback.

It can be seen that in the whole process, although the host application 1 does not have the function of connecting to wifi, the service of the applet is guaranteed by calling the host application 2 with the function of connecting to wifi by sharing the terminal capability in the terminal device. In addition, there is no need to repeatedly integrate the function code for connecting to wifi in the host application 1, which saves resources.
