Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings. The embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
To better illustrate the present disclosure, the relevant native application invocation is first described. FIG. 1 illustrates an exemplary flow diagram of a related native application invocation method.
As shown in fig. 1, before calling a native application, the web page view 101 needs to determine whether the currently running operating system is an operating system of a first category or an operating system of a second category. For example, the first class of operating system may be an iOS operating system and the second class of operating system may be an Android operating system. Other operating systems may be used as desired. On the basis, if the native application is the first-class operating system, the native application is called by adopting a calling mode 102 provided by the first-class operating system. By way of example, the iOS operating system provides the following calling methods: window. webkit. messagehandles. < functionName >. postmessage (params) >. If the second type operating system is adopted, the native application is called by adopting a calling mode 103 provided by the second type operating system. As an example, the Android operating system provides the following calling methods: < objectname.funtionancame () >. That is, in the development stage of the application, the technician needs to consider the difference of the operating systems used by different platforms, which increases the development complexity of the application.
To solve the technical problems in the related native application calling manner described above, the present disclosure will be described in detail with reference to the accompanying drawings in conjunction with embodiments.
FIG. 2 is a schematic diagram of one application scenario of a native application invocation method of some embodiments of the present disclosure.
In the application scenario of fig. 2, whether native application 202 of the first type of operating system or native application 203 of the second type of operating system, web page view 201 may be invoked by managing class objects in conjunction with method names. Among other reasons, the reason why it is possible to call the native application 202 of the first class operating system by combining the management class object with the method name is that: script injection is performed when the first type of operating system exposes the web page.
It should be noted that, in practice, the native application 202 of the first type of operating system and the native application 203 of the second type of operating system may be run on two different devices, or may be run on the same device, for comparison, the disclosure is not limited thereto.
With continued reference to fig. 3, a flow 300 of some embodiments of a native application invocation method in accordance with the present disclosure is illustrated. The native application calling method comprises the following steps:
In some embodiments, the first class operating system is generally not supported for such calling of management class objects plus method names. For example, the first class operating system may be an iOS operating system. In practice, the call mode provided by the iOS operating system is: window. webkit. messagehandles. < functionName >. postmessage (params) >. Wherein, the funtionanName is the name of the method to be called. In practice, the operating system provides some users with a web page view of the exposed web page. For example, the iOS operating system provides wkbwebview, a control for exposing web pages.
In some embodiments, an execution subject (e.g., a terminal device) of the native application invocation method may inject a preset script into the webpage view in response to the initialization of the webpage view for exposing the webpage running the first class operating system. The preset script may be pre-included in the sdk (software Development kit) of the application. The preset script can be used for creating the management class object after the webpage view is injected. After the preset script is injected into the webpage view, the script can generate a target management object when running.
The target management class object may be obtained by initializing a target management class, which is predefined in a preset script, as an example. For example, the target management class object may be JDBridge, and the target management class (JDBridge class) is defined by:
the management class can be initialized in the following way, and a management class object JDbridge is obtained:
var JDbridge＝new JDBridgeClass()；
on the basis, the corresponding method can be called in a mode of adding the method name to the management class object. Jdbridge. camera () can be used to call a camera, for example.
In some embodiments, on the basis of step 301, in response to receiving a first call request including a target management class object and a target method name, the execution subject may call a Native application (Native APP) running on a first class operating system through a call method corresponding to the first class operating system. In practice, the native application may be a third-party application written using a native program and running based on a local operating system of a terminal device such as a smartphone. Corresponding to native applications, there is also a Web application (Web App) that runs based on a browser. The web page described in this disclosure is a page in a web application.
For example, in response to receiving a call request: jdbridge. callcamera (), because the management class definition already described in step 301 exists, at this time, window. webkit. message handlers [ callcamera ]. postMessage (), that is, the calling method corresponding to the first class operating system, is substantially called, so as to implement calling the native application.
In some embodiments described above, invoking native applications based on management class objects and method names is implemented on a first class operating system that does not otherwise support the invocation of management class objects plus method names. In practice, this calling mode is also supported by the second class of operating systems themselves. Therefore, the calling modes of the first-class operating system and the second-class operating system can be unified, and the currently running operating system does not need to be judged, so that the development complexity is reduced.
With further reference to FIG. 4, a flow 400 of further embodiments of a native application invocation method is illustrated. The flow 400 of the native application calling method includes the following steps:
In some embodiments, the method name may match a method name used to invoke a corresponding method in the second class of operating systems. For example, the first class operating system and the second class operating system may agree in advance to have the method names used to invoke the camera unified as: a callcamera. Therefore, the first operating system and the second operating system can be called by the same method name, the universality of the application calling method on different operating systems is further increased, and the development complexity is further reduced.
In some embodiments, specific implementations of the remaining features of steps 401-402 and technical effects thereof may refer to those embodiments corresponding to fig. 3, and are not described herein again.
And step 403, in response to a second call request sent by the webpage view running on the second category operating system, calling the native application running on the second category operating system through the mapping class object and the method name included in the second call request.
In some embodiments, the calling method corresponding to the second category of operating system includes a class and a method name. That is, the second class operating system may be an operating system that itself supports calls by way of class objects plus method names. For example, the Android operating system.
On the basis, responding to a second calling request sent by the webpage view running on the second category operating system. The native application running on the second class operating system is invoked by the mapping class object and the method name included in the second invocation request, wherein the mapping class object may be predefined.
Optionally, the mapping class object may be defined by the following steps: first, a target mapping class is defined that applies to the second class of operating systems. Then, a method to be called is created in the target mapping class, and a mapping class object is obtained. For example, for an Android operating system, object mapping may be performed through addjavascript interface () of WebView, and an Android class in mapping relation with a Javascript object is defined: AndroidtoJs. Then, creating a method which needs to be called by Javascript in the class, and annotating by @ Javascript interface. Therefore, Javascript can be called by adding the method name to the class android Js. Due to the object mapping, calling the Android objects is equal to calling the Android mapped objects.
As can be seen from fig. 4, the flow 400 of the native application invocation method in some embodiments corresponding to fig. 4 adds a step of invoking the native application on the second type of operating system, compared to the description of some embodiments corresponding to fig. 3. Thus, the solutions described in these embodiments may be applicable to the second class of operating systems. In addition, because the method names used for calling the corresponding methods in the first class of operating systems and the second class of operating systems are matched, the universality of the application calling method on different operating systems is increased, and the development complexity is further reduced.
