It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The method for acquiring the data of the applet can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 obtains the first applet and sends a data request to the server 104 through the network; when receiving the data returned by the server 104 according to the data request, the first applet may be run; hijacking a loading interface of the first applet during the running process of the first applet; acquiring a data acquisition program, and injecting codes of the data acquisition program into codes of a first applet to generate a second applet; the loading interface of the second applet is the same as the loading interface of the first applet; calling a loading interface of the second applet to load codes of the second applet and generating pages of the second applet; and acquiring the data in the page of the second applet by the data acquisition program. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, there is provided an applet data acquisition method comprising the steps of:
Step 202, a first applet is obtained and run.
An applet refers to an application that is implemented based on a host program and that can be used without a download installation. The host program may be a WeChat, a payment device, or other application program, etc.
The terminal opens a host program of the first applet, acquires the first applet from the host program, and runs the first applet. In one embodiment, the first applet may be obtained from an applet collection of the host program. The applet collection may be a collection of applets used by the user in history, or a collection of applets collected by the user, but is not limited thereto.
In another embodiment, the camera of the terminal can be called by the host program, so that the camera is opened to scan the scanning code corresponding to the first applet, and the first applet is obtained. The scan code may be a bar code, a two-dimensional code, or the like.
After the terminal acquires the first applet, an operation instruction generated by the first applet is received, the code of the first applet is acquired based on the operation instruction, and the code of the first applet is analyzed, so that the first applet is operated.
Step 204, hijacking the loading interface of the first applet during the running process of the first applet.
The execution environment of the first applet includes a rendering layer and a logic layer. The rendering layer of the first applet is used for displaying the data of the first applet, for example, displaying a default page of the first applet on a display interface of the terminal. The logic layer of the first applet is used for generating and processing the data of the first applet, such as transferring the data, checking the data, calling the interface, etc. The loading interface of the first applet refers to an interface for loading the code of the first applet so that the first applet can be presented on the display interface of the terminal.
Specifically, the hook technology is adopted to hijack the loading interface of the first applet during the running process of the first applet. Among other things, hook technology is a special message handling mechanism that can monitor various event messages in a system or process, intercept messages directed to a target window, and handle them. The hook technology can be used to monitor the occurrence of specific events in the system, perform specific functions such as screen word taking, log monitoring, keyboard and mouse input interception, etc.
Step 206, acquiring a data acquisition program, and injecting the code of the data acquisition program into the code of the first applet to generate a second applet; the loading interface of the second applet is identical to the loading interface of the first applet.
The data acquisition program refers to a program for automatically capturing data of the first applet according to a certain rule. The data acquisition program can be designed by a developer. The second applet refers to the applet from which the data is to be acquired. The second applet contains the code of the first applet and the code of the data acquisition program.
It will be appreciated that the second applet includes the code of the data acquisition program and the code of the first applet, and the data acquisition program is a program for acquiring data in the second applet page, and does not change the underlying architecture such as the loading interface of the first applet, so that the basic functions, basic architecture, etc. of the second applet are the same as those of the first applet, and the loading interface of the second applet is the same as that of the first applet.
And step 208, calling a loading interface of the second applet to load codes of the second applet, and generating a page of the second applet.
The page of the second applet may include data such as a picture, text, link, and video, and may include elements such as a button (wx-button), an input box (wx-input), and a navigation bar (wx-navigator).
And the terminal calls a loading interface of the second applet to load the codes of the second applet, namely the codes of the first applet and the codes of the data acquisition program, and generates a page of the second applet. In the pages of the second applet, default pages of the first applet, e.g., initial pages of the first applet, may be included; dynamic pages may also be included. Dynamic pages refer to pages that are jumped by clicking on links, buttons, etc.
Step 210, acquiring data in the page of the second applet by the data acquisition program.
The data acquisition program acquires the data in the page of the second applet, which may include data such as pictures, texts, links, videos, and the like, and may also include elements such as buttons and input boxes. The data acquisition program may also grab the network request sent by the second applet to the server.
The data acquisition program refers to a program for automatically capturing data of the second applet according to a certain rule. When the page is the default page of the first applet, the data in the default page is acquired by the data acquisition program. When the page comprises elements such as a link, a button, an input box, a navigation bar and the like, the data acquisition program can simulate user operation according to the elements, click the elements such as the link, the button, the navigation bar and the like or acquire input data and the like, so that the page jumps to the next page, and then the data in the next page is acquired through the data acquisition program.
The data acquisition method of the applet acquires a first applet and runs the first applet; hijacking a loading interface of the first applet during the running process of the first applet; acquiring a data acquisition program, and injecting codes of the data acquisition program into codes of a first applet to generate a second applet; the loading interface of the second applet is the same as the loading interface of the first applet; calling a loading interface of the second applet to load codes of the second applet and generating pages of the second applet; the first applet is operated based on the host program, the codes of the data acquisition program are injected into the codes of the first applet, and the data acquisition program and the first applet can operate based on the same bottom layer framework, the same operation logic and the like of the host program, so that the data in the page of the second applet can be acquired through the data acquisition program contained in the second applet, and the function of acquiring the data of the second applet is realized.
By injecting the code of the data acquisition program into the code of the first applet, the data acquisition program has the ability to access DOM (Document Object Model ) data of the first applet as well as the ability to access the native interface of the host program of the first applet. Therefore, the data acquisition program can interact with the host program of the first applet, for example, call the payment function of the host program, so that the data of the interaction between the second applet and the host program can be acquired, and the more complete data of the second applet can be acquired.
The code of the data acquisition program is injected into the code of the first applet, the element types defined by the DOM (Document Object Model ) in the first applet can be directly acquired, the data of the second applet can be accurately acquired based on the element types defined by the DOM in the first applet, and the problem that page elements in the applet cannot be normally rendered due to the fact that different element types are adopted by a browser in the process of acquiring the data of the applet by adopting network data acquisition is avoided, so that the data of the applet cannot be acquired through the network data acquisition.
It can be understood that the event mechanism of the applet depends on the lower-level architecture of the applet, and when the browser acquires data from the applet, the browser cannot trigger and process the events correctly by adopting network data acquisition in the conventional technology. In this embodiment, the code of the data acquisition program is injected into the code of the first applet to generate the second applet, so that the second applet is also operated based on the applet infrastructure defined by the developer, and the data of the second applet can be acquired through the data acquisition program, thereby realizing the function of acquiring the data of the second applet.
Further, after the data in the page of the second applet is acquired by the data acquisition program, it includes: scanning the data in the acquired page of the second applet to obtain the security attribute of each data; based on the security attributes of the respective data, a security report for the second applet is generated.
The security properties of the data may be e.g. secure, unsafe, further the security properties of the data may be violence, pornography, people, scenery, etc. And scanning the acquired data in the page of the second applet to obtain the security attribute of each data, so that the security of the second applet can be evaluated more accurately.
When the data is text, acquiring a reference keyword, matching the reference keyword with the text, and determining the safety attribute of the text according to the matching result. For example, the reference keyword may be a (a represents violence), and when the text obtained from the page of the second applet matches a, indicating that a is included in the text, the security attribute of the text may be "unsafe-violence".
In one embodiment, as shown in FIG. 3, the second applet is a take-away applet, text is obtained from the second applet, and a security report of the text in the second applet is generated. The text content with the number of 1 is "A", the fact that the text content "A" is a word representing violence is detected, so that the security attribute of the generated text content "A" is "unsafe-violence", the order in which the text content "A" is located is also obtained as "B1", and the obtaining time of the text content "A" is 2019-05-31 09:47:21.
The text content with the number of 2 is "11 months", and the word representing time is detected as "11 months", so that the security attribute of generating the "11 months" is "security-time", and the order in which the text content is "11 months" is also acquired as "B2", and the acquisition time of the text content "11 months" is 2019-05-31 09:48:26.
The text content with the number of 3 is a 'high new area', and the 'high new area' is detected to be a word representing an address, so that the safety attribute of the generated 'high new area' is a 'safety-address', an order in which the text content is the 'high new area' is also acquired as a 'B2', and the acquisition time of the text content 'high new area' is 2019-05-31 09:48:38.
The text content with the number of 4 is 'service attitude difference', and the detection of the 'service attitude difference' is a word representing evaluation, so that the security attribute for generating the 'service attitude difference' is 'security-evaluation', and an order in which the text content is 'service attitude difference' is 'B3' can be obtained, and the obtaining time of the text content 'service attitude difference' is 2019-05-31 09:50:21.
When the data is a picture or a video, detecting whether the picture or the video contains sensitive information or not; when the picture or video contains sensitive information, the security attribute of the picture or video can be 'unsafe'; when no sensitive information is contained in a picture or video, the security attribute of the picture or video may be "security". The sensitive information can be violence, pornography, abuse and the like.
In one embodiment, a picture is obtained from a page of the second applet and a security report of the obtained picture is generated. As shown in fig. 4, the acquired picture is numbered 1, the picture address of the picture is "A1", the security attribute of the picture is "security-person" detected, and the acquisition time of the picture may be 2019-05-31 09:47:21.

When the data is a link, a reference link set can be acquired from the server, the link is matched with each reference link in the reference link set, and the security attribute of the link is determined according to the matching result. The reference link set also comprises reference security attributes corresponding to the reference links. When the link acquired from the second applet matches a reference link in the reference link set, the reference security attribute corresponding to the matching reference link is used as the security attribute of the link acquired from the second applet. For example, the link acquired from the second applet is B1, and when the link B1 matches with the reference link B2, the security attribute corresponding to the reference link B2 is pornography, and the security attribute corresponding to the link B1 is pornography.
As shown in fig. 5, when the host program of the first applet is a letter, 502 refers to a letter client, and includes an application program of the letter itself and the first applet. The running environment of the applet is divided into a rendering layer where WXML (WeiXin Markup Language) templates, WXSS (WeiXin Style Sheets) styles (DOM data), rendering logic, etc. work and a logic layer where JS (JavaScript) scripts work. WXML is a set of label language designed by a framework, and can construct the structure of a page by combining a basic component and an event system. WXSS is a set of style languages used to describe the component styles of WXML. DOM (Document Object Model ) refers to the standard programming interface of the processing extensible markup language recommended by the W3C (World Wide Web Consortium, web consortium) organization. The rendering logic comprises DOM operation interface and other data, and is realized by JS script.
The interface of the rendering layer of the first applet is rendered using 504, webView; the logical layer runs JS script using 506, i.e., the JsCore thread. The first applet has multiple interfaces so the render layer has multiple webviews. Communication between the rendering layer and the logic layer is relayed via 508, native (application of the WeChat itself), and the logic layer sends a network request to be forwarded via 508, native, to the third party server 510. And the data sent by the third party server 510 is also forwarded to the logical layer via 508, native. The third party server 510 communicates with the WebSocket client 502 in the terminal. WebSocket is a protocol that performs full duplex communication over a single TCP (Transmission Control Protocol ) connection.
In one embodiment, the code of the first applet includes a first render layer code and a first logic layer code, and the code of the data acquisition program includes a second render layer code and a second logic layer code.

The rendering layer is used to present the data, for example, to display the individual elements in an interface. The logic layer is used for generating data and processing the data, such as transferring the data, checking the data, calling an interface and the like. The first rendering layer code refers to the code of the rendering layer of the first applet. The first logical layer code refers to the code of the logical layer of the first applet. The second rendering layer code refers to the code of the rendering layer of the data acquisition program. The second logical layer code refers to the code of the logical layer of the data acquisition program.
Specifically, the second rendering layer code of the data acquisition program is injected to the tail part of the first rendering layer code of the first applet, so as to obtain the rendering layer code of the second applet; and calling a v8 engine (JavaScript engine) interface to inject the second logic layer code into the first logic layer code of the first applet to obtain the logic layer code of the second applet.
In this embodiment, the rendering layer code of the second applet includes the second rendering layer code of the data acquisition program, and the logic layer code of the second applet includes the second logic layer code of the data acquisition program, so that the data acquisition program can interact with the first applet on the rendering layer, for example, acquire data, add data, modify data, etc., and can verify the data on the logic layer, so that more complete and accurate data can be acquired.
In one embodiment, invoking the load interface of the second applet to load code of the second applet, generating a page of the second applet comprises: calling a loading interface of the second applet, loading a rendering layer code of the second applet, and checking logic of the rendering layer code of the second applet by adopting the logic layer code of the second applet; and when the logic verification of the rendering layer code of the second applet is passed, generating a page corresponding to the rendering layer code of the second applet.
And the terminal calls a loading interface of the second applet, loads the rendering layer code of the second applet, and can generate a page corresponding to the rendering layer code of the second applet. Logic of the rendering layer code of the second applet may include whether an API (Application Programming Interface, application program interface) called in the rendering layer code of the second applet is correct, whether contents of elements in the rendering layer code of the second applet correspond to types of elements, and the like. For example, the type of the element is a mobile phone number, and the content of the element is a picture, and the content of the element does not correspond to the type of the element.
When the logic verification of the rendering layer code of the second applet passes, a page corresponding to the rendering layer of the second applet can be generated more accurately, so that more accurate data are obtained, and the problems that the generated page is disordered, messy codes exist and the like due to the fact that the logic of the rendering layer code of the second applet is inaccurate are avoided.

In one embodiment, the terminal may obtain the correspondence between the input type and the input data from a local memory. In another embodiment, the terminal may also acquire the correspondence between the input type and the input data from the data acquisition program. In another embodiment, the terminal may further obtain a correspondence between the input type and the input data from the background server. The background server may be a server corresponding to a host program of the first applet. For example, if the host program of the first applet is a WeChat, the terminal may obtain the correspondence between the input type and the input data from the WeChat server.
The jump instruction comprises the address of the next page, and the next page is searched and loaded according to the address of the next page, and is displayed on the display interface of the terminal.
The elements of the input type may be buttons, input boxes, links, navigation bars, and the like.

For example, the input types of the input box can be divided into: a telephone number input box, an authentication code input box, a password input box, a picture input box, an account input box, a text input box, an address input box and the like.
When the input type element is a link, the corresponding input data is a click command or other preset commands and the like; inputting input data such as a click command or other preset commands into the link, namely clicking the link, generating a jump command, and jumping to the next page.
In this embodiment, the user operation is simulated by the data acquisition program, such as clicking a link, inputting corresponding data in an input box, clicking a button, clicking a navigation bar, and the like, so that the user can jump to the next page, thereby acquiring the data in the next page, and more completely acquiring the data of the second applet.

Acquiring input data corresponding to the input type through a data acquisition program, including:
step 702, obtaining input data corresponding to the input type through a second rendering layer code of the data obtaining program.
The terminal acquires the corresponding relation between the input type and the input data in advance, and when the type of the element acquired by the data acquisition program is the input type, acquires the input data matched with the input type of the element from the corresponding relation between the input type and the input data.
Inputting the input data into the element, generating a jump instruction, comprising:
step 704, the input data is input into the element, and the input data is checked by the second logic layer code of the data acquisition program.
It can be understood that the corresponding data is input in the input box, so that the next page can be accurately skipped. For example, the login button inputs a click command to accurately jump to the next page; and the corresponding verification code is input in the verification code input box, so that the next page can be skipped. For another example, when the login button inputs a picture or a text, the input data does not correspond to the element and cannot jump to the next page; when a click command is input in the mobile phone number input box, the input data does not correspond to the element and can not jump to the next page.
Therefore, the input data is checked through the second logic layer code of the data acquisition program, so that the input data corresponds to the element of the input type, and the next page can be skipped.
Step 706, when the input data is verified, generates a jump instruction.
In this embodiment, input data corresponding to an input type is acquired through a second rendering layer code of the data acquisition program; and inputting the input data into the elements, and checking the input data through a second logic layer code of the data acquisition program, so that the input data corresponds to the elements of the input type, and a jump instruction is generated, thereby jumping to the next page.

Step 812 is performed to traverse all elements in the page. Step 814 is performed to determine if data for all elements in the page has been obtained. When the determination is yes, that is, when the data of all the elements in the page has been acquired, the execution step 806 is returned, and each page is traversed. When the judgment is no, that is, when the data of all the elements in the page are not acquired, step 816 is executed, and the simulation operation is performed on the elements of the input type through the data acquisition program. Specifically, input data corresponding to an input type is acquired through a data acquisition program; input data into the element, generate a jump instruction.
