Description
Technical Field
The invention belongs to the technical field of information, and particularly relates to a method and a system for calling a local function by a WeChat client.
Background
The wechat is a common social software for people, and a wechat client running on a user side (such as a user computer and a user mobile terminal) is often used as a client (program) of other network applications besides a social function of chatting and the like, for example, the wechat client can be used as a browser to access a Web system (a Web site or a Web application system) through a built-in browser function, and can be used as a client (program) to interact with a server of wechat public signals and wechat applet applications. However, the wechat client has a certain functional limitation as a client of a Web system, wechat public number, and wechat applet, and it cannot directly call a local functional component (such as a data compression functional component, a password functional component, etc.) of a computing device (such as a user computer, a user mobile terminal, etc.) where the wechat client operates, or interact with the local functional component in a network communication manner to call a special function provided by the functional component.
Disclosure of Invention
The invention aims to provide a method and a system for calling functions provided by local function components (modules and programs) by a WeChat client.
Aiming at the aim of the invention, the technical scheme provided by the invention comprises a method for calling the local function by the WeChat client and a corresponding system.
The method for calling the local function by the WeChat client is specifically as follows.
When a WeChat client as a client of a Web system or a WeChat application (such as a WeChat public number and a WeChat applet application) needs to call a function provided by a function component local to a computing device (such as a user computer and a user mobile terminal) where the WeChat client operates, submitting a function call request to an intermediary server (through a network) by the WeChat client, and then transmitting the function call request to the function component by the intermediary server (through the network) or obtaining the function call request submitted by the WeChat client from the intermediary server by the function component (through the network);
the functional component returns a processing result to the intermediary server after obtaining the function calling request submitted by the WeChat client and completing function processing;
the intermediary server returns the processing result to the wechat client, or the wechat client obtains the calling processing result from the intermediary server;
the intermediary server is a system which is used as a data transmission and exchange bridge between the WeChat client and the local functional component of the computing device where the WeChat client operates; the mediating server is the system that the wechat client is allowed to access (in wechat community number, wechat applet applications, systems that the wechat client can allow access to are restricted).
The mode of the WeChat client side for exchanging data (including submitting function calling request and returning processing result) with the function component comprises a session connection mode and a non-session connection mode;
the mode with session connection means that before data exchange is carried out between the WeChat client and the functional component, network session connection is established through an intermediary server, and then data (such as function call request and processing result) is exchanged through session connection;
the session-free connection mode means that before data exchange is carried out between the WeChat client and the functional component, network session connection is not established through the intermediary server, the WeChat client directly submits a function calling request to the intermediary server, and the functional component inquires and requests to acquire the function calling request submitted to the functional component from the intermediary server; after verifying and determining that the functional component is a submission object of the function invocation request submitted by the WeChat client, the intermediary server returns the function invocation request to the functional component; the functional component returns a processing result to the intermediary server after finishing the function processing; the WeChat client requests to acquire a processing result from the intermediary server; and the intermediary server returns the processing result to the WeChat client after verifying that the WeChat client is the return object of the processing result.
The functional component is prompted to be started by the WeChat client when the WeChat client needs to invoke the function of the functional component or has been started (automatically by the computing device or manually by the user) before the WeChat client needs to invoke the function of the functional component.
If the data exchange (including function call request submission and processing result return) between the wechat client and the functional component is a session connection mode, and the functional component is started before the wechat client needs to call the function of the functional component (automatically started by a computing device or manually started by a user), the functional component establishes a session connection with the intermediate server after being started, and maintains the session connection with the intermediate server (the session connection belongs to a part of a complete session connection between the wechat client and the functional component).
If the mode of data exchange (including function call request submission and processing result return) between the WeChat client and the functional component is a mode without session connection, and the functional component is started (automatically by a computing device or manually by a user) before the WeChat client needs to invoke the function of the functional component, the functional component regularly queries the intermediary server whether the function call request submitted to the functional component exists.
On the basis of the method for calling the local function by the WeChat client, a corresponding system for calling the local function by the WeChat client can be constructed, wherein the system comprises the WeChat client, a functional component which is local to a computing device and is used for providing a preset function and an intermediary server, and the WeChat client runs; when the WeChat client as a Web system or a WeChat application client needs to call the function provided by the local function component of the computing device where the WeChat client operates, the WeChat client calls the local function according to the method for calling the local function by the WeChat client and obtains a processing result.
As can be seen from the above description, with the method and system of the present invention, when the wechat client, as a client of the Web system or the wechat application, needs to invoke a function provided by a function component local to the computing device where the wechat client operates, the wechat client may complete component function invocation through an intermediary server and obtain a processing result.

Detailed Description
The present invention will be further described with reference to the following examples.
Examples 1,
In this embodiment, when the wechat client needs to call the function provided by the local function component of the computing device (such as a user computer and a user mobile terminal) where the wechat client operates as a client of a Web system or wechat application (such as wechat public number and wechat applet application), the wechat client and the function component establish a network session connection through an intermediary server, and then the wechat client submits a function call request to the intermediary server through the session connection, and the intermediary server transmits the function call request to the function component through the session connection; after the functional component obtains the function call request submitted by the WeChat client and completes function processing, the functional component returns a processing result to the intermediary server through session connection; the intermediary server returns the processing result to the WeChat client through the session connection.
Establishing session connection between the wechat client and the functional component through the intermediary server is similar to establishing session connection between programs respectively located in two different computing devices through an intermediary system, and many mature schemes exist, and are not described herein again.
The function component is prompted by the wechat client to start when the wechat client needs to invoke the function of the function component or has started (automatically by the computing device or manually by the user) before the wechat client needs to invoke the function of the function component.
In this embodiment, if the functional component is initiated (either automatically by the computing device or manually by the user) before the WeChat client needs to invoke the function of the functional component, the functional component establishes a session connection with the intermediary server upon initiation and maintains a session connection with the intermediary server (this session connection is part of the full session connection between the WeChat client and the functional component).
Examples 2,
In this embodiment, when the wechat client needs to call the function provided by the local function component of the computing device (such as a user computer and a user mobile terminal) where the wechat client operates as a client of a Web system or wechat application (such as wechat public number and wechat applet application), the wechat client does not establish a network session connection with the function component, but the wechat client directly submits a function call request to the intermediary server, and the function component queries and requests to obtain the function call request submitted to itself from the intermediary server; after verifying and determining that the functional component is a submission object of the function invocation request submitted by the WeChat client, the intermediary server returns the function invocation request to the functional component; the functional component returns the processing result to the intermediary server after finishing the function processing; the WeChat client requests to acquire a processing result from the intermediary server; and the intermediary server returns the processing result to the WeChat client after verifying that the WeChat client is the return object of the processing result.
The WeChat client and the functional component exchange data through the intermediary server in a session-free manner, which is similar to the way that programs respectively located in two different computing devices exchange data through an intermediary system in a session-free manner, and a mature scheme exists, and is not described herein again.
The functional component is prompted by the wechat client to start when the wechat client needs to invoke the function of the functional component or has already started (automatically by the computing device or manually by the user) before the wechat client needs to invoke the function of the functional component.
In this embodiment, if the functional component is started (automatically by the computing device or manually by the user) before the WeChat client needs to invoke the function of the functional component, the functional component periodically queries the broker server whether there is a function invocation request submitted to the functional component.
On the basis of the method for calling the local function by the WeChat client, a system for implementing the corresponding calling of the local function by the WeChat client can be constructed, wherein the system comprises the WeChat client, a functional component which is local to a computing device and is used for providing a preset function and an intermediary server, and the WeChat client runs on the computing device; when a wechat client is used as a client of a Web system or wechat application and needs to call functions provided by local function components of a computing device where the wechat client operates, the wechat client, the function components and the intermediary server call the local functions by implementing the method for calling the local functions by the wechat client, which comprises the steps of implementing embodiments 1 and 2, completing the call of the function components and obtaining a processing result.
Other specific technical implementations not described are well known to those skilled in the relevant art and will be apparent to those skilled in the relevant art.
