[0002] When a user sends a request to the corresponding server through an application (application, app) (also referred to as an application), it is usually necessary to carry signature information. The server authenticates the user through the signature information, and only after the identity authentication is passed can the user be provided with the corresponding service. If the signature information can be obtained, the request can be sent to the server through the machine to improve the access efficiency. Usually, the target code library containing the signature algorithm (the signature information can be obtained through the signature algorithm) in the application software is disassembled into an assembly file to obtain the signature algorithm, and then the signature information is obtained through the signature algorithm, and a request is sent to the server based on the signature information. Disassembly requires converting machine language into assembly language, which is difficult to analyze and has high requirements for developers who perform disassembly work, resulting in low efficiency in obtaining signature information.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0023] The embodiments of the present application provide an information acquisition method, device, computer equipment and computer readable storage medium. The information acquisition device can be integrated in a computer equipment, which can be a server or a terminal.

[0024] The terminal may include a mobile phone, a wearable smart device, a tablet computer, a laptop computer, a personal computer (PC), and a vehicle-mounted computer.

[0025] Among them, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, as well as big data and artificial intelligence platforms.

[0026] Terminals may include mobile phones, wearable smart devices, tablet computers, laptop computers, and personal computers (PCs), etc.

[0027] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0028] This embodiment will be described from the perspective of an information acquisition device, which may be integrated into a computer device, which may be a server or a terminal. Figure 1 As shown, the specific process of the information acquisition method is as follows:

[0029] 101. Obtain an application package of a target application.

[0030] Among them, the target application can be an application software (application, app) that needs to obtain signature information, the application package can be an installation package of the target application, and the installation package can include files required for the target application to run. For example, the target application is an application software running on an Android device, and the application package of the target application is an Android application package (Android application package, APK), which includes compiled code files, file resources, native resource file certificates, and manifest files, etc.

[0031] For example, the application package of the target application may be downloaded through a browser or other means.

[0032] 102. Decompress the application package to obtain the object code library in the application package.

[0033] The target code library may be a file containing a signature algorithm, for example, a dynamic library.

[0034] For example, the application package may be decompressed to obtain a plurality of program files contained in the application package, and the target code library may be obtained from the plurality of program files.

[0035] The target code library usually has a fixed suffix name. For example, the suffix name of the dynamic library is .so. In one embodiment, the step of "decompressing the application package to obtain the target code library in the application package" may specifically include:

[0036] Decompress the application package to obtain multiple program files contained in the application package;

[0037] Traverse the suffix names of multiple program files;

[0038] The program files whose suffix names meet the requirements are determined as the object code library.

[0039] For example, take the target code library as a dynamic library as an example: the dynamic library usually uses .so as the file suffix name. After decompressing the application package, you can get multiple program files in the application package. Traverse the suffix names of all program files in the application package and determine the program file with the suffix name .so as the target code library.

[0040] 103. For the target code library, a corresponding calling interface is constructed, and the calling path of the calling interface calling the target code library is the same as the calling path of the target application calling the target code library.

[0041] The calling interface may be an interface for calling a signature algorithm in a target code library to obtain signature information.

[0042] For example, the method of calling the signature algorithm of the target code library can be determined by querying the logic code in the program file obtained by decompressing the application package, and a corresponding interface can be constructed according to the determined method. The logic code in the application package can be called through the constructed interface to obtain the signature information.

[0043] In one embodiment, the calling path of the signature algorithm may be determined, and a corresponding interface may be constructed according to the calling path, that is, the step of "constructing a corresponding calling interface for a target code library", which may specifically include:

[0044] Get the program name of the application package, get the class name of the encryption class that calls the signature algorithm to generate the signature in the application package, and the name of the method contained in the encryption class;

[0045] Determine the calling path of the signature algorithm based on the name of the encryption class and the names of the methods contained in the encryption class;

[0046] Build a calling interface based on the calling path.

[0047] Among them, the encryption class is the class that calls the signature algorithm through methods in the logic code. The class is the basis for implementing information encapsulation in object-oriented programming.

[0048] For example, the logic code of the target application calls the signature algorithm of the dynamic library through method B in class A to obtain signature information. Correspondingly, the calling path is the path formed by the application package, class A and method B. A JNI layer interface class (i.e., calling interface) with the same program name, the same class name and the same method name as the application package is constructed. The JNI layer interface is a Java Native Interface (JNI). The API provided by the application package can be called through JNI. The method B in class A of the application package can be called through the constructed JNI layer interface, thereby realizing the calling of the signature algorithm to generate signature information.

[0049] In one embodiment, the method may be implemented in a local development environment built by a software development tool based on a native program interface, that is, the step of "determining the calling path of the signature algorithm according to the name of the encryption class and the name of the method included in the encryption class" may specifically include:

[0050] Install software development tools;

[0051] Configure the local development environment based on software development tools;

[0052] Based on the local development environment, build a calling interface according to the name of the encryption class and the names of the methods contained in the encryption class.

[0053] The software development tool may be a software development tool based on a native program interface, such as a native development kit, referred to as NDK. Programs developed using this tool run directly in a native language rather than a virtual machine.

[0054] For example, it can be as follows Figure 2 As shown, download and install NDK, configure the corresponding local development environment, and create a project in the local development environment. Place the dynamic library in the application package of the target application in the call directory of the project, build a JNI layer call interface with the same program name, class name, and method name as the application package in the project, compile it, and call the code in the application package through the call interface to generate signature information.

[0055] 104. Generate signature information by calling the signature algorithm in the target code library through the calling interface.

[0056] The signature algorithm may be an MD5 algorithm or a SHA1 algorithm.

[0057] Among them, the signature information can be the information required by the server to authenticate the client. The client generates the signature information through the signature algorithm and transmits the signature information to the server as a request parameter. The server receives the request and verifies the signature information at the same time. It generates signature information for the request parameters through symmetric encryption and compares it with the signature information transmitted by the client. If the signatures are inconsistent, the server needs to intercept the request; if the signature information is verified successfully, the interface can be accessed.

[0058] For example, the signature information may be generated by calling a signature algorithm in a target code library through a calling interface.

[0059] In one embodiment, the required parameter information can be determined through the code field in the logic code, and the corresponding parameters can be passed in to generate the signature information, that is, the step of "generating the signature information by calling the signature algorithm in the target code library through the calling interface" can specifically include:

[0060] Traverse the encryption class and the logic code in the methods contained in the encryption class;

[0061] Determine the parameter information required by the signature algorithm;

[0062] According to the parameter information, corresponding parameters are passed to the calling interface to generate signature information based on the parameters through the calling interface.

[0063] The parameter information may be information required by the signature algorithm, such as a timestamp and a random number, etc. The specific parameter information depends on the signature algorithm.

[0064] For example, the logic code in the encryption class and the methods contained in the encryption class can be traversed to determine the parameter information passed into the signature algorithm. The required parameter information can be determined by keyword matching. For example, if the logic code contains timestamp, it can be determined that the passed-in parameter information has a timestamp.

[0065] By determining the parameter information required by the signature algorithm, the corresponding parameters can be generated and passed into the calling interface. The calling interface calls the signature algorithm through the calling path and generates signature information based on the parameters.

[0066] Optionally, the application package can also be decompiled, which reverses the machine language into high-level programming language. During the programming process, developers usually define fields based on functions. The corresponding information of the fields can be determined through the code fields in the high-level programming language, such as user ID or timestamp, and then the parameter information can be determined.

[0067] In one embodiment, the step of “introducing corresponding parameters into the calling interface according to the parameter information, so as to generate signature information based on the parameters by calling the interface” may specifically include:

[0068] According to the parameter information, the corresponding parameters are passed to the calling interface;

[0069] The parameters are encrypted by calling the interface to generate signature information.

[0070] For example, the parameters may be passed into the calling interface, and the calling interface may encrypt the parameters by calling the signature algorithm through the calling path to generate signature information.

[0071] Optionally, after obtaining the signature information, the signature information and the parameters passed into the calling interface can be added to a uniform resource locator (URL), and the server can be accessed through the URL to obtain data, and the server can be authenticated.

[0072] Generate a data acquisition request based on the signature information;

[0073] Send a data acquisition request to the server corresponding to the target application to obtain data from the server.

[0074] For example, the signature information may be added to the data acquisition request, and a data acquisition request may be sent to a server corresponding to the target application. If the signature information is verified by the server, the corresponding data may be acquired from the server.

[0075] As can be seen from the above, the embodiment of the present application obtains the application package of the target application; decompresses the application package to obtain the target code library in the application package; then, for the target code library, a corresponding calling interface is constructed, and the calling path of the calling interface to call the target code library is the same as the calling path of the target application calling the target code library; finally, the signature information is generated by calling the signature algorithm in the target code library through the calling interface. This solution constructs a calling interface that calls the signature algorithm with the same calling path as the target application, and the signature algorithm can be called through the calling interface to obtain the signature information. The signature information can be obtained without disassembling the target code library, thereby improving the efficiency of obtaining the signature information.

[0076] In order to better implement the information acquisition method provided in the embodiment of the present application, an information acquisition device is also provided in one embodiment. The meanings of the terms are the same as those in the above-mentioned information acquisition method, and the specific implementation details can refer to the description in the method embodiment.

[0077] The information acquisition device can be integrated into a computer device, such as Figure 3 As shown, the information acquisition device may include: an acquisition unit 301, a decompression unit 302, a construction unit 303 and a calling unit 304, which are specifically as follows:

[0078] Acquisition unit 301: used to acquire the application package of the target application.

[0079] For example, the application package of the target application may be downloaded through a browser.

[0080] Decompression unit 302: used for decompressing the application package to obtain the target code library in the application package.

[0081] For example, the application package may be decompressed to obtain a plurality of program files contained in the application package, and the target code library may be obtained from the plurality of program files.

[0082] In one embodiment, the decompression unit 302 may include a decompression subunit, a traversal subunit, and a determination subunit, specifically:

[0083] Decompression subunit: used to decompress the application package to obtain multiple program files contained in the application package;

[0084] Traversal subunit: used to traverse the suffix names of multiple program files;

[0085] Determine subunit: used to determine program files whose suffix names meet the requirements as target code libraries.

[0086] For example, take the target code library as a dynamic library as an example: the dynamic library usually uses .so as the file suffix name. After decompressing the application package, multiple program files in the application package can be obtained. The suffix names of all program files in the application package are conveniently determined, and the program files with the suffix name .so are determined as the target code library.

[0087] The construction unit 303 is used to construct a corresponding calling interface for the target code library. The calling path of the calling interface calling the target code library is the same as the calling path of the target application calling the target code library.

[0088] For example, the method of calling the signature algorithm of the target code library can be determined by querying the logic code in the program file obtained by decompressing the application package, and a corresponding interface can be constructed according to the determined method. The logic code in the application package can be called through the constructed interface to obtain the signature information.

[0089] In one embodiment, the construction unit 303 may include an acquisition subunit, a determination subunit, and a construction subunit, specifically:

[0090] Get subunit: used to get the name of the application, the name of the encryption class that calls the signature algorithm to generate the signature in the application, and the name of the method contained in the encryption class;

[0091] Determine subunit: used to determine the calling path of the signature algorithm according to the name of the encryption class and the names of the methods contained in the encryption class;

[0092] Construction subunit: used to build a call interface according to the call path.

[0093] For example, the logic code of the target application calls the signature algorithm of the dynamic library through method B in class A to obtain signature information. Correspondingly, the calling path is the path formed by the application package, class A and method B. A JNI layer interface class (i.e., calling interface) with the same file name, class name and method name as the application package is constructed. The JNI layer interface is a Java Native Interface (JNI). The API provided by the application package can be called through JNI. Method B in class A of the application package can be called through the constructed JNI layer interface, thereby realizing the calling of the signature algorithm to generate signature information.

[0094] In one embodiment, the determination subunit may include an installation module, a configuration module, and a construction module, specifically:

[0095] Installation module: used to install software development tools;

[0096] Configuration module: used to configure the local development environment based on software development tools;

[0097] Building module: used to build a calling interface based on the local development environment, according to the name of the encryption class and the names of the methods contained in the encryption class.

[0098] For example, it can be as follows Figure 2 As shown, download and install NDK, configure the corresponding local development environment, and create a project in the local development environment. Place the dynamic library in the application package of the target application in the call directory of the project, build a JNI layer call interface with the same package name, type, and method name as the application package in the project, compile it, and call the code in the application package through the call interface to generate signature information.

[0099] The calling unit 304 is used to call the signature algorithm in the target code library through the calling interface to generate signature information.

[0100] For example, the signature information may be generated by calling a signature algorithm in a target code library through a calling interface.

[0101] Optionally, the calling unit 304 may include a traversal subunit, a determination subunit, and an input subunit, specifically:

[0102] Traversal subunit: used to traverse the encryption class and the logic code in the methods contained in the encryption class;

[0103] Determine subunit: used to determine the parameter information required by the signature algorithm;

[0104] The input subunit is used to input corresponding parameters to the calling interface according to the parameter information, so as to generate signature information based on the parameters through the calling interface.

[0105] For example, the logic code in the encryption class and the methods contained in the encryption class can be traversed to determine the parameter information passed into the signature algorithm. The required parameter information can be determined by keyword matching. For example, if the logic code contains timestamp, it can be determined that the passed-in parameter information has a timestamp.

[0106] By determining the parameter information required by the signature algorithm, the corresponding parameters can be generated and passed into the calling interface. The calling interface calls the signature algorithm through the calling path and generates signature information based on the parameters.

[0107] In one embodiment, the incoming subunit may include an incoming module and an encryption module, specifically:

[0108] Incoming module: used to pass corresponding parameters to the calling interface according to parameter information;

[0109] Encryption module: used to encrypt parameters and generate signature information by calling the interface.

[0110] For example, the parameters may be passed into the calling interface, and the calling interface may encrypt the parameters by calling the signature algorithm through the calling path to generate signature information.

[0111] Optionally, the information acquisition device may further include a generating unit and a sending unit, specifically:

[0112] Generating unit: used to generate a data acquisition request according to the signature information;

[0113] Sending unit: used to send a data acquisition request to the server corresponding to the target application to obtain data from the server.

[0114] For example, the signature information may be added to the data acquisition request, and a data acquisition request may be sent to a server corresponding to the target application. If the signature information is verified by the server, the corresponding data may be acquired from the server.

[0115] As can be seen from the above, the embodiment of the present application obtains the application package of the target application through the acquisition unit 301; the decompression unit 302 decompresses the application package to obtain the target code library in the application package; then, for the target code library, the corresponding calling interface is constructed through the construction unit 303, and the calling path of the calling interface to call the target code library is the same as the calling path of the target application calling the target code library; finally, the calling unit 304 calls the interface to call the signature algorithm in the target code library to generate signature information. This solution constructs a calling interface with the same calling path as the target application to call the signature algorithm, and the signature algorithm can be called through the calling interface to obtain the signature information. The signature information can be obtained without disassembling the target code library, thereby improving the efficiency of obtaining the signature information.
