Detailed Description

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The applet communication method and the applet communication device provided by the embodiment of the disclosure are suitable for an application scene of data communication between an applet and a host program of the applet. Each of the applet communication methods provided in the embodiments of the present disclosure may be executed by an applet communication apparatus, which may be implemented by software and/or hardware and is specifically configured in an electronic device.

For ease of understanding, the present disclosure first details each applet communication method.

Referring to fig. 1, an applet communication method includes:

and S101, responding to the trigger operation of the host function in the applet, and generating a host service request.

The host function is a function provided by a host program of the applet, and the function can be understood as an extension of an existing function in the applet framework.

The triggering operation of the host function in the applet may be a click, a slide, a drag, or the like of a preset area or a preset control in the applet. The present disclosure does not set any limit to the specific number of clicks, sliding distance, dragging distance, and the like.

S102, calling a host service method corresponding to the host service request to realize a corresponding service function; the attribute type to which the host service method belongs is inherited from a preset extension base class in the applet framework, and an extension binding method for binding the execution reference data of the applet for the attribute type is realized in the preset extension base class.

The host service method can be understood as an example method written in a host program required to be called for processing the host service request. The corresponding service function can be realized by the small program by calling the host service method. Typically, different hosted service requests correspond to different hosted service methods.

For example, when a control is closed by touching a network in an applet, a network close request is generated. At this time, the applet cannot provide the applet shutdown function itself, and the network shutdown function needs to be implemented by calling the network shutdown method in the host program.

The attribute type of the host business method is used for representing the class identifier of the abstract class corresponding to the host business method.

The base class is also called a parent class, which refers to a inherited class containing the same characteristics, and is defined as a class type containing the commonality of all entities in the object-oriented design. The preset extension base class in the present disclosure may be understood as a base class preset in an applet framework for the applet client to perform function extension, and a base class for the host program to extend the applet function.

The extended binding method may be understood as a method for providing a subclass (also called a derived class) that inherits the preset extended base class with a function of executing reference data binding, and the method is a core layer logic code of an applet client and is independent of actual services. Where the execution reference data may be understood as data required to support the applet to implement the business functions of the host. For example, at least one of the context of the front-end code of the applet execution and basic properties of the applet itself (such as the applet identification and the applet category, etc.) may be included.

Illustratively, the calling of the host service method is performed through a global variable exposed to the front end of the applet by the applet client, a preset extension base class, an attribute type to which the host service method belongs and the host service method, so that a service function corresponding to the host service method is realized. For example, if the host service method is a stopWifi () method for implementing a WiFi (wireless fidelity) shutdown function, the attribute type of the method is a WiFi bridge class, the preset extension base class is an extension class, and the global variable of the applet front end is _ nassan, then the applet front end can call the stopWifi () method of the host program through _ nassan.

In an optional embodiment, a host service method corresponding to the host service request may be determined according to the description information of each service method; determining the attribute type corresponding to the host business method, the preset extension base class and the overall variable of the small program client based on the class diagram in the development and design stage; constructing a calling logic code according to the determined global variable of the applet client, the preset extension base class, the attribute type corresponding to the host service method and the host service method; and running the calling logic code and calling the host service method corresponding to the host service request.

In an optional embodiment, the method for calling the host service corresponding to the host service request may be: and determining a host service method corresponding to the host service request according to the corresponding relation between each service request and each service method in the small program method call list, thereby avoiding the occurrence of the condition that the corresponding service function cannot be realized due to wrong method call. Meanwhile, the determination of the host service method corresponding to the host service request is carried out in a table look-up mode, so that the determination efficiency of the host service method is improved, and the improvement of the small program communication efficiency is facilitated.

The method and the device for binding the small program inherit the attribute type of the host business method in the host program to the preset extension base class in the small program frame and realize the extension binding method for supporting the data required by the small program to realize the business function of the host in the preset extension base class, thereby realizing the function extension of the small program by the host program. Because the applet client does not need to expose an expansion binding method irrelevant to the service to the host program, the communication safety between the applet and the host program is improved. In addition, the host program does not need to be classified to realize the extension binding method, so that the development difficulty and the understanding cost of the host program are reduced. Meanwhile, under a system operation mechanism, especially an IOS operation mechanism, the host program has different host program classification realization same extension binding methods, thereby avoiding the loss of partial host functions caused by classification realization of the same extension binding methods.

On the basis of the above technical solutions, the present disclosure also provides an alternative embodiment. In this alternative embodiment, a binding process between the property type to which the host business method belongs and the applet will be described in detail. In the present disclosure, reference may be made to the description of the foregoing embodiments.

Referring to fig. 2, an applet communication method includes:

s201, when the small program runs, obtaining attribute types of each host service method in a preset extension base class in a small program frame.

For example, when the applet runs, the attribute types to which the host service methods in the preset extension base class belong in the applet framework may be obtained, and an attribute list including the attribute types may be constructed.

S202, binding the execution reference data of the small program for each attribute type according to the extension binding method realized in the preset extension base class.

The extended binding method may be understood as a method for providing a function of binding reference data to a subclass (also called a derived class) inheriting the preset extended base class, and the method is a core layer logic code of an applet client and is unrelated to actual services. Where the execution reference data may be understood as data required to support the applet to implement the business functions of the host. For example, at least one of the context of the execution front-end code of the applet, basic properties of the applet itself (such as the applet identity and the applet class), and the like.

Illustratively, the property list may be traversed, and the execution reference data of the applet may be bound for each property type in the property list according to an extension binding method implemented in the preset extension base class.

In an optional embodiment, before binding the execution reference data of the applet for each property type according to the extended binding method, the method further includes: identifying a parent class inherited by each attribute type; and eliminating the attribute types of the parent class different from the preset extension base class.

Illustratively, the parent class inherited by each attribute type in the attribute list can be traversed; and removing the attribute types of the parent class and the preset extension base class in the attribute list so as to update the attribute list. Correspondingly, the updated attribute list is traversed subsequently, and the execution reference data of the small program is bound for each attribute type in the updated attribute list according to the extension binding method realized in the preset extension base class.

In general, the parent class inherited by the attribute type is a preset extension base class. When the parent class inherited by the attribute type is empty or the parent class inherited by the attribute type is different from the preset extension base class, the situation that the host program expands the applet wrongly may occur, so that the attribute types different from the parent class and the preset extension base class need to be removed, and the influence on the normal operation of the applet is avoided.

In an alternative embodiment, the extended binding method may include an environmental binding method; correspondingly, according to the extended binding method, the binding of the execution reference data of the applet for each attribute type may be: and binding the context environment of the front-end code executed by the small program for each property type according to the environment binding method.

The front-end code of the applet is usually js (js) (javascript) logic code, and the host business method implemented under each attribute type in the host program is usually OC (object-C, C-extended object-oriented programming language) logic code. In order to ensure that the applet can call the OC logic code in the host program, the execution environment of the JS code, i.e., the context (JSContext), needs to be bound for each property type of the host program.

When different host programs perform function extension on the same applet, the attribute types of the different host programs all need to be bound by context environment, and the situation of class classification realization of the corresponding logic codes of the environment binding method occurs at the moment. Due to the same classification under the IOS runtime mechanism, if the methods are of the same name, the situation of being covered will occur, and further the situation of losing part of host functions occurs, and the use experience is influenced. According to the method, the environment binding methods are classified according to the attribute types, and the implementation of the specific method under the corresponding attribute types is replaced by the implementation mode in the preset extension base class, so that the context environment of the front-end code executed by the small program is uniformly bound to different attribute types when the small program runs, and the situation that part of implementation is covered is avoided.

In another alternative embodiment, the extended binding method may include a base class property setting method; correspondingly, according to the extended binding method, the binding of the execution reference data of the applet for each attribute type may be: and setting the base class attribute for each attribute type according to the base class attribute setting method.

The base class attribute is used for representing attribute information of a preset extension base class in the applet. Optionally, the base class attribute may include identification information of the applet for uniquely characterizing the applet, thereby distinguishing between different applets. Or alternatively, the base class attribute may include class information of the applet for distinguishing the applet class. For example, the applet type may be a mini-game or an applet.

It can be understood that the richness of the base class property content is improved by detailing the base class property into the identification information and/or the category information of the applet, and data support is provided for binding the property type in the host program and the execution reference data of the applet. The identification information and/or the category information of the applet are only specific descriptions of the contents included in the base class attribute, and should not be construed as specific limitations of the contents included therein.

According to the method and the device, the base class attribute is set for each attribute type when the applet runs, so that the situation that the applet runs wrongly is avoided when each host program runs the applet, and the accuracy of the applet running process is improved.

And S203, responding to the trigger operation of the host function in the applet, and generating a host service request.

And S204, calling a host service method corresponding to the host service request to realize a corresponding service function. Wherein, the attribute type of the host service method is inherited from the preset extension base class.

According to the embodiment of the method and the device, the native class, namely the preset extension base class, is unified to bind the execution reference data for each attribute type when the applet runs, so that high cohesion of an extension process is realized, and errors in classification extension are avoided. In addition, when the host program expands the applet framework, only the attribute type of the host service method needs to be defined, core code logics which are irrelevant to services, such as an expansion binding method, do not need to be concerned, and the understanding cost and the expansion difficulty of the host are reduced. Meanwhile, the original class of the applet client does not need to be adapted and upgraded, and the applet client does not need to expose core code logic to the host program, so that convenience and safety of applet extension are improved.

As an implementation of each of the above applet communication methods, the present disclosure also provides an alternative embodiment of an execution device implementing the applet communication method. Referring further to fig. 3, an applet communication device 300 comprises: a host service request generation module 301 and a host service method calling module 302.

In an optional embodiment, the apparatus further comprises:

In an optional embodiment, the apparatus further comprises:

and the host service method determining module is used for determining the host service method corresponding to the host service request according to the corresponding relation between each service request and the service method in the small program method call list.
