The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminal devices 101, 102, 103 to interact with the server 105 via the network 104 to receive or send messages or the like. The terminal devices 101, 102, 103 may have installed thereon various communication client applications, such as a web browser application, a search-type application, an instant messaging tool, and the like.

The server 105 may be a server providing various services, such as a background server providing support for pages displayed on the terminal devices 101, 102, 103.
It should be noted that the WebView-based data injection method provided in the embodiment of the present application is generally executed by a server, and accordingly, the WebView-based data injection device is generally configured in the server.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Referring to FIG. 2, FIG. 2 illustrates an embodiment of a WebView-based data injection method.
It should be noted that, if the result is substantially the same, the method of the present invention is not limited to the flow sequence shown in fig. 2, and the method includes the following steps:
s1: and acquiring a data injection request generated by the WebView terminal, and acquiring binary data corresponding to the data injection request through the Native terminal.
Specifically, when data needs to be injected into the WebView end, the WebView end generates a data injection request, and after the server obtains the data injection request, the Native end obtains corresponding binary data. For example, when camera real-time frame data needs to be injected to a WebView end, a camera needs to be turned on and the real-time frame data needs to be acquired, the real-time frame data is sent to a Native end first, and the real-time frame data exists in a form of binary data, that is, a form of byte array.
The Webview end is an engine based on webkit, can analyze DOM elements and display a control of an html page, has the same principle as a browser for displaying the page, and can be regarded as a browser. The Native terminal refers to an Android Native terminal and is a client based on an Android system. The android end corresponds to a Native layer, the Native layer is developed by C + + generally relative to the bottom layer of a Java layer, and the Native layer is deployed with common local services, link libraries and the like. In the embodiment, the binary data is intercepted and converted through the communication between the Native terminal and the Webview terminal, so that the binary data is injected into the Webview terminal.
Referring to fig. 3, fig. 3 shows an embodiment of step S1, which includes:
s11: and acquiring a data injection request generated by the WebView terminal.
S12: and acquiring a search path corresponding to the data injection request by analyzing the data injection request.
S13: and acquiring binary data corresponding to the search path through a Native terminal.
Specifically, because the data injection request generated by the WebView end has different data sources and different stored paths corresponding to the data injection request, the data injection request needs to be analyzed, and different types of data requests are distinguished through a Path function, that is, a search Path corresponding to the data injection request is obtained. And then corresponding binary data is obtained according to the search path.
The Path function is a DOS (disk operating system) Path setting command, the function is a search Path of an executable file of the equipment, when the executable file is operated, the DOS searches the file in a current directory firstly, and if the executable file is found, the DOS is operated; if the file cannot be found, the file is searched in the directory one by one according to the Path set by the Path function. The search path refers to a path in which the data injection request corresponds to storage or queryable of data. For example, if the data corresponding to the data injection request is the data of the requested camera real-time frame, the generated uniform resource locator is "http:// pa. If the real-time recording data is requested, the uniform resource locator is set to be http:// pamina.
In the implementation, the corresponding search path is obtained by analyzing the data injection request, and the binary data is obtained according to the search path, so that different data injection requests are distinguished, the corresponding binary data is quickly obtained, and the efficiency of binary injection into the WebView end is improved.
S2: and when the WebView end receives the uniform resource locator corresponding to the binary data, a GET request is initiated to the uniform resource locator through the browser object.
Specifically, the binary data is acquired at the Native end, but the binary data cannot reach the WebView end. Therefore, a uniform resource locator corresponding to the binary data needs to be generated at the Native terminal, the uniform resource locator is sent to the WebView terminal, and the WebView terminal is informed of new generation of the binary data, so that when the WebView terminal receives the uniform resource locator corresponding to the binary data, a GET request is initiated to the uniform resource locator through the browser object.
The browser object is XMLHttpRequest, and the XMLHttpRequest (XHR) is an Application Program Interface (API) object, wherein the method can be used for transmitting data at the browser and server sides. This object is provided by the JavaScript environment of the browser. The purpose of obtaining data from XMLHttpRequest is to continuously modify a loaded page, which is the underlying concept of the Ajax design. The protocol used by XMLHttpRequest is different from HTTP, and not only data in XML format but also JSON, HTML, or plain text can be supported. In the embodiment of the application, the GET request is initiated to the uniform resource locator by calling the method in the browser object.
The GET request is a request for requesting data from a server. In the embodiment of the application, a GET request is initiated to the uniform resource locator through the browser object, so that a WebView terminal initiates a request for acquiring binary data.
Referring to fig. 4, fig. 4 shows an embodiment of step S2, which includes:
s21: and acquiring the uniform resource locator corresponding to the binary data.
S22: and sending the uniform resource locator to the WebView terminal in a mode of calling JavaScript codes.
Specifically, binary data is acquired at a Native terminal, and a uniform resource locator corresponding to the binary data is generated. In order to reduce the data volume and improve the transmission efficiency, a uniform resource locator is sent to the WebView end by calling a JavaScript code, so that the WebView end can be informed of new binary data generation at the Native end.
The mode of calling the JavaScript code means that the JavaScript code is injected into the JavaScript by evaluateJavaScript, and the uniform resource locator is sent to the WebView end.
S23: and when the WebView end receives the uniform resource locator, calling the browser object to initiate a GET request to the uniform resource locator.
Specifically, the uniform resource locator is received at the WebView end by calling a JavaScript code form. And calling a browser object, namely calling a method in the XMLHttpRequest, at the WebView end to initiate a GET request to the uniform resource locator.
In the implementation, the JavaScript code is called to send the uniform resource locator to the WebView end, and the GET request is initiated at the WebView end, so that the binary data acquisition request is initiated at the WebView end, the binary data can be conveniently injected into the WebView end subsequently, and the efficiency of injecting the binary data into the WebView end can be improved.
Referring to fig. 5, fig. 5 shows a specific implementation manner after step S23, which includes:
s231: and responding to the corresponding type of the browser object to acquire a preset data type.
S232: and converting the data type of the binary data into a preset data type by adopting a traversal mode, wherein the preset data type comprises an arraybuffer type and a blob type.
Specifically, in this embodiment of the present application, the type corresponding to the response browser object refers to a response xmlhttprequest. It allows us to manually set the type of data returned. If it is set to an empty string, it will use the default "text" type. In the embodiment of the application, a preset data type is obtained by responding to an xmlhttprequest.
The preset data type is set according to the actual situation and comprises an arraybuffer type and a blob type. The arraybuffer type refers to typed arrays. A blob type refers to a binary large object, which is a container that can store binary files.
In the implementation, the corresponding type of the browser object is responded to obtain the preset data type, and the data type of the binary data is converted into the preset data type in a traversal mode, so that the binary data is converted into the corresponding type, and the binary data is convenient to identify subsequently.
S3: intercepting the GET request through an interceptor preset by a Native terminal, and judging whether the uniform resource locator meets a preset condition to obtain a judgment result.
Specifically, an interceptor is preset at a Native end, the GET request is intercepted after the WebView end initiates the GET request, and whether a uniform resource locator corresponding to the GET request meets a preset condition is judged, so that a judgment result is obtained.
The preset condition is a character string set according to a domain name suffix and used for distinguishing whether the domain name corresponding to the uniform resource locator meets the requirement or not. For example, the preset condition is "com", if there is a character matching "com" in the domain name in the uniform resource locator, the result is that the uniform resource locator meets the preset condition, otherwise, the uniform resource locator does not meet the preset condition.
Further, before the GET request is intercepted by an interceptor preset at the Native terminal, an interceptor is preset at the Native terminal. The method comprises the steps that a preset Interceptor is preset with a class realizing an Interceptor interface or inherits an abstract class abstract Interceptor, defined interceptors are registered in a configuration file, and the registered and defined interceptors are quoted when an interception function is needed. In this embodiment of the present application, an interceptor registered and defined in a configuration file may set an intercepted domain name, for example, pamina.
Referring to fig. 6, fig. 6 shows a specific implementation manner of step S3, which includes:
s31: and intercepting the GET request through an interceptor preset by a Native terminal.
S32: and identifying the domain name corresponding to the uniform resource locator.
S33: and matching the domain name with the character strings corresponding to the preset conditions to obtain a judgment result.
Specifically, after the interceptor preset by the Native terminal identifies that the WebView terminal initiates the GET request, the GET request is intercepted. And acquiring a uniform resource locator corresponding to the GET request, thereby identifying a domain name corresponding to the uniform resource locator, and judging whether the domain name meets preset conditions or not, thereby achieving a judgment result.
The Domain Name (Domain Name), also called network Domain, is the Name of a certain computer or computer group on the Internet, which is composed of a string of names separated by points, and is used for positioning and identifying the computer during data transmission.
Specifically, since the domain name has a domain name suffix of ". com", ". net", ". cn", ". edu", ". top", ". xyz", and the like. Therefore, the preset condition can set the corresponding character strings according to the domain name suffixes, if the suffixes in the domain name corresponding to the uniform resource locator are matched with the character strings in the preset condition, the judgment result is that the domain name meets the preset condition, otherwise, the domain name does not meet the preset condition.
In the implementation, a GET request is intercepted through an interceptor preset by a Native terminal, a domain name corresponding to a uniform resource locator is identified, the domain name is subjected to character string matching with a character string corresponding to a preset condition to obtain a judgment result, the GET request interception and the judgment result acquisition are realized, corresponding binary data can be favorably sent to a WebView terminal, and therefore the efficiency of injecting the binary data into the WebView terminal can be favorably improved.
S4: if the judgment result is that the uniform resource locator meets the preset condition, the binary data is obtained by analyzing the uniform resource locator.
Specifically, if a suffix in the domain name corresponding to the uniform resource locator matches a character string in the preset condition, the result of the determination is that the uniform resource locator meets the preset condition. And analyzing the uniform resource locator to acquire a path corresponding to the binary data, thereby acquiring the binary data.
S5: and converting the binary data into a Web object, and returning the Web object to the WebView end.
Specifically, the Web object is a WebResourceResponse object, which is response information encapsulating a Web resource, and the response information of the Web resource includes: response data stream, encoding, MIME type, response header, status code and status description, etc.
Specifically, in the embodiment of the present application, binary data is converted into a WebResourceResponse object through an eval () function of JavaScript. The eval () function uses a JavaScript compiler that can parse JSON text and then generate a WebResourceResponse object. And then returning the Web object to the WebView end.
S6: and when the condition that the Web object returns to the WebView end is monitored, performing data type conversion on the Web object according to a preset data type so as to inject binary data into the WebView end.
Specifically, when a browser object of the WebView end monitors the return of a Web object, namely the return of the Web object is monitored through XMLHttpReques, the attribute of the Web object is obtained, and the attribute of the Web object is converted into a corresponding data type according to the preset data type, so that binary data is injected into the WebView end.
In the embodiment, a data injection request generated by a WebView terminal is obtained, and binary data is obtained; when the WebView end receives the uniform resource locator, a GET request is initiated; intercepting the GET request by an interceptor preset by a Native terminal, judging whether the uniform resource locator meets a preset condition, and if so, analyzing the uniform resource locator to obtain binary data; converting binary data into a Web object; and when the condition that the Web object returns to the WebView end is monitored, performing data type conversion on the Web object according to a preset data type so as to inject binary data into the WebView end. According to the embodiment of the invention, the interceptor intercepts the GET request, the binary data is converted into the Web object, and finally the data type conversion is carried out on the Web object, so that the binary data is injected into the WebView terminal without transcoding in a JavaScript environment, and the efficiency of injecting the binary data into the WebView terminal is improved.
Referring to fig. 7, an embodiment of step S6 is illustrated, which includes:
s61: and monitoring the Web object through a browser object of the WebView end.
S62: and when the condition that the Web object returns to the WebView end is monitored, acquiring the attribute of the Web object.
S63: and performing data type conversion on the attribute of the Web object according to a preset data type by responding to the request of the browser object so as to inject binary data into the WebView terminal.
The attribute of the Web object refers to a response data stream of the WebResourceResponse object, that is, corresponding data information. The request to respond to the browser object is implemented via an XMLHttpRequest response attribute that can return the body of the response. The type of return may be one of arraybuffer, blob, Document, JavaScript Object, or DOMString. In the embodiment of the present application, the preset data types include: arraybuffer type, blob type, then data can be returned as arraybuffer type or blob type by responding to a request by a browser object.
In the implementation, the Web object is monitored through a browser object of a WebView end, the attribute of the Web object is obtained, the attribute of the Web object is subjected to data type conversion according to a preset data type by responding to a request of the browser object, so that binary data is injected into the WebView end, and finally the binary data is injected into the WebView end.
It is emphasized that, to further ensure the privacy and security of the binary data, the binary data may also be stored in a node of a block chain.
