[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The proposed solution can be implemented based on a terminal with data processing capabilities, such as a mobile phone, computer, server, or cloud platform.

[0053] Next, from the perspective of the terminal, we will introduce one of the payment system interface management methods of this solution, referring to... Figure 1 The process may include:

[0054] Step S100: Obtain the interface call request information.

[0055] The interface call request information includes the domain name information of the target interface.

[0056] Specifically, the terminal can obtain the interface call request information input by the technician, which includes the domain name information of the target interface.

[0057] Step S110: Using the domain name information, retrieve the corresponding target encryption / decryption algorithm information, target login status information, and target interface parameters from the database.

[0058] Specifically, the terminal's database pre-stores multiple encryption / decryption algorithm information, login status information, and interface parameters. The corresponding target encryption / decryption algorithm information, target login status information, and target interface parameters can be retrieved from the database using domain name information.

[0059] Step S120: Obtain the encryption / decryption value of the target interface parameter using the target encryption / decryption algorithm information.

[0060] Specifically, the terminal can encrypt or decrypt some fields in the target interface parameters to ensure data security, and can use the target encryption / decryption algorithm information to obtain the encryption / decryption values ​​of the target interface parameters.

[0061] Step S130: Calculate the function signature value using the encryption / decryption value and the preset interface parameter value.

[0062] Specifically, the function signature value is one of the data used to perform legitimate call checks. The terminal can calculate the function signature value using the encryption / decryption value and preset interface parameter values.

[0063] Step S140: Send the encryption / decryption value, function signature value, and target login status information to the target interface for the target interface to perform a legitimate call check.

[0064] Specifically, the target interface can perform a legitimate call check based on the encryption / decryption value, function signature value, and target login state information. The terminal can send the encryption / decryption value, function signature value, and target login state information to the target interface for the target interface to perform a legitimate call check.

[0065] Step S150: Call the target interface.

[0066] If the valid call check of the target interface passes, then the target interface is invoked.

[0067] Specifically, once the target interface confirms that the call is valid, it can respond to the terminal's call request, and the terminal can then call the target interface.

[0068] In this embodiment, since the obtained domain name information is used to call the pre-stored encryption / decryption algorithm and login status information to achieve the purpose of calling the corresponding interface, compared with the prior art, the tedious steps of inputting encryption / decryption algorithm and login status are saved for each interface call, thus improving the work efficiency of calling different interfaces.

[0069] Furthermore, in some embodiments of this application, the information of each supported interface can be uploaded to the terminal's database in the form of a JAR file in advance, so that the relevant data can be called later when using it. Before step S100, obtaining the interface call request information, this solution may also include the following steps:

[0070] Step S160: Obtain the JAR package uploaded by the user corresponding to each domain name information, and store the information in the JAR package into the database of each return interface respectively. The JAR package includes the name of each return interface corresponding to the domain name information, the encryption and decryption algorithm information corresponding to the domain name information, the function signature method, the login state information, and the parameters of each interface. Each return interface includes an interface information return interface, a login state information return interface, and an encryption and decryption method information return interface.

[0071] Specifically, users can upload multiple JAR packages corresponding to various domain names via the terminal. The information in the JAR packages can be automatically stored in the corresponding database according to the returned interfaces, facilitating the return interfaces to call the corresponding data. The JAR packages include the names of each returned interface corresponding to the domain name information, encryption / decryption algorithm information corresponding to the domain name information, function signature methods, login status information, and parameters of each interface. Each returned interface includes an interface information return interface, a login status information return interface, and an encryption / decryption method information return interface. The interface information return interface is used to return all interface names of the calling domain and the interface parameters corresponding to each interface name. The login status information return interface is used to return the calling function of the login status information corresponding to the calling domain. The encryption / decryption method information return interface is used to return the encrypted / decrypted value obtained by encrypting / decrypting the field when the interface parameter has an encryption / decryption field.

[0072] Furthermore, the following describes step S110, which involves using the domain name information to retrieve the corresponding target encryption / decryption algorithm information, target login status information, and target interface parameters from the database. Figure 2 As shown, the process may include:

[0073] Step S111: Send the domain name information to the interface information return interface, login status information return interface, and encryption / decryption method information return interface.

[0074] Specifically, the terminal can send domain name information to the interface information return interface, login status information return interface, and encryption / decryption method information return interface, so that these interfaces can call relevant data based on the domain name information.

[0075] Step S112: Use the interface information to return the target interface parameters corresponding to the domain name information.

[0076] Specifically, the terminal can use the interface information to return the target interface parameters corresponding to the domain name information.

[0077] Step S113: Use the login status information return interface to call the target login status information corresponding to the domain name information.

[0078] Specifically, the terminal can use the login status information return interface to call the target login status information corresponding to the domain name information.

[0079] Step S114: Use the encryption / decryption method information return interface to call the target encryption / decryption algorithm information corresponding to the domain name information.

[0080] Specifically, the terminal can use the encryption / decryption method information return interface to call the target encryption / decryption algorithm information corresponding to the domain name information.

[0081] In this embodiment, the actual login status information and encryption / decryption algorithm information are cumbersome. The corresponding information is retrieved through various return interfaces, saving the step of having to input the cumbersome encryption / decryption algorithm and login status every time the interface is called.

[0082] Furthermore, in some embodiments of this application, the encryption and decryption security measures for fields differ among interfaces. Some interfaces support encrypted fields, while others support decrypted fields. To enable the reading of different encrypted and decrypted fields, the encryption and decryption method information return interface may include an encryption method information return interface or a decryption method information return interface. The process of calling the target encryption and decryption algorithm information corresponding to the domain name information using the encryption and decryption method information return interface is described below. The specific steps are as follows:

[0083] Step S1141: When the target interface parameter corresponding to the domain name information contains an encryption field, the target encryption algorithm information corresponding to the domain name information is called by returning the encryption method information.

[0084] Specifically, when the target interface supports encrypted fields, the corresponding target interface parameters can include encrypted fields, and the terminal can use the encryption method information to return the interface call to the target encryption algorithm information corresponding to the domain name information.

[0085] Step S1142: When the target interface parameter corresponding to the domain name information contains a decryption field, the decryption method information return interface is used to call the target decryption algorithm information corresponding to the domain name information.

[0086] Specifically, when the target interface supports decryption fields, the corresponding target interface parameters can include decryption fields, and the terminal can use the decryption method information to return the interface call to the target decryption algorithm information corresponding to the domain name information.

[0087] Furthermore, in this embodiment of the application, when the security and confidentiality measures of the interface are upgraded and maintained, and the encryption and decryption algorithms of the corresponding encryption and decryption fields are changed, the corresponding upgraded and maintained encryption and decryption algorithms can be added to the encryption and decryption method information return interface.

[0088] In some embodiments of this application, depending on the encryption and decryption algorithms supported by the interface, the target encryption and decryption algorithm information may include target encryption algorithm information or target decryption algorithm information. The process of obtaining the encryption and decryption value of the target interface parameter using the target encryption and decryption algorithm information in step S120 above will be described below. This process may include the following steps:

[0089] Step S121: When the target interface parameter corresponding to the domain name information contains an encrypted field, the encrypted value of the target interface parameter is obtained using the target encryption algorithm information.

[0090] Specifically, after the terminal calls the target encryption algorithm information through the interface returned by the encryption method information, it can use the target encryption algorithm information to calculate and obtain the encrypted value of the target interface parameter.

[0091] Step S122: When the target interface parameter corresponding to the domain name information contains a decryption field, the decryption value of the target interface parameter is obtained using the target decryption algorithm information.

[0092] Specifically, after the terminal calls the target decryption algorithm information through the interface returned by the decryption method information, it can use the target decryption algorithm information to calculate and obtain the decryption value of the target interface parameter.

[0093] In some embodiments of this application, the function signature value, as part of the verification data security, can be calculated by inputting a pre-agreed numerical value. The process of calculating the function signature value using the encryption / decryption value and the preset interface parameter value in step S130 is described below. The specific steps are as follows:

[0094] Step S131: Using the encryption / decryption value, parse the encryption / decryption field in the target interface parameter to obtain the target interface parameter in plaintext state.

[0095] Specifically, the terminal can use the encrypted / decrypted value to parse the encrypted / decrypted fields in the target interface parameters to obtain the target interface parameters in plaintext state.

[0096] Step S132: Based on the target interface parameters and preset interface parameter values ​​in plaintext state, call the corresponding function signature interface to obtain the function signature value.

[0097] Specifically, the preset interface parameter value can be a pre-agreed value. The terminal can call the function signature interface corresponding to the target interface based on the target interface parameter in plaintext state and the preset interface parameter value to obtain the function signature value.
