Example 1

Referring to FIG. 1, the present embodiment discloses a front-end and back-end cross-language communication method based on AES (Advanced Encryption Standard, Advanced Encryption Standard) encryption, which is applied to an application and a server, wherein the application is also called a front-end application, It is set on electronic devices such as on-site power distribution terminals, electronic computers, mobile phones or tablet computers in the form of applications and APPs; the server is also called back-end service, which is set on the back-end server in the form of applications and management software. The application is implemented in the first programming language, and the server is implemented in the second programming language. It should be noted that, according to different application environments, those skilled in the art can select the first programming language and the second programming language from different programming languages. . The following description takes the JavaScript programming language and the Java programming language as examples, wherein the JavaScript programming language is used as the first programming language and the Java programming language is used as the second programming language. Since the application and the server are implemented in different programming languages, in order to realize cross-language communication between the application and the server, this embodiment defines a unified communication interface protocol, wherein the communication interface protocol uses JSON (JavaScript Object Notation , JavaScript Object Notation) format. The communication interface protocol solves the problem that the current application request interface protocol is inconsistent, and facilitates the management of the protocol and the application. In this embodiment, the communication interface protocol includes a request protocol and a response protocol. The request protocol is mainly used in front-end applications, and the response protocol is mainly used in back-end services. Among them, Table 1 shows the parameter description of the request protocol in this embodiment, and Table 2 shows the parameter description of the response protocol. It should be noted that the parameter value of the protocol is set by those skilled in the art according to actual needs. Therefore, In this embodiment, specific parameter values are omitted.

Table 2

In practical applications, the application side can be different application programs configured on the electronic computer, such as a power dispatch management platform, the application program is set with a corresponding "application name", the application program has one or more function modules, and each function module is set There is a corresponding "module name", a function module has one or more function controls, each function control is implemented by a corresponding function function, and each function function is set with a corresponding "function name". Before using the application or function module, The user is required to log in or verify the authority to obtain the "user login ID", thereby enhancing the security of the distribution automation system. Even if there is a problem during the operation, it can be traced by querying the user login ID, which is beneficial to the distribution of power distribution. Problem investigation of automated systems. It should be noted that the application name, module name, function name or user login ID can be a string of numbers, an English code name or a string of characters. When the user needs to obtain data from the database of the background server, the application side encapsulates the specific parameters of the user's request information in "data". The server feeds back parameters such as "success or not", "system time returned by the response", "business data" to be returned, or "business processing exception information" according to the actual processing result. In this way, a unified protocol basis can be provided for cross-language communication between the application and the server.

In the above discussion, the communication interface protocol is defined in this embodiment, and the front-end and back-end cross-language communication method based on AES encryption in this embodiment is discussed in detail below. The front-end and back-end cross-language communication method based on AES encryption in this embodiment includes steps S101 to S106. in,

S101. In response to a user's input request, an application terminal organizes request data through a first programming language based on a request protocol.

For example, the application end exists in the form of an application program, such as a power dispatch management platform. The application program has one or more functional modules, and the functional module has one or more functional controls. The user obtains data from the database of the background server through the functional controls. After the user triggers the corresponding function control, the application terminal responds to the user's input request and organizes the request data through the JavaScript programming language based on the above request protocol. For example, when the user uses the power dispatch management platform to view the power dispatch data, the request data includes power The application name of the dispatch management platform, the module name of the current function module, the function name corresponding to the current control, the user login ID, and the specific instructions for viewing power dispatch data, etc.

S102. The application terminal performs AES encryption on the request data by using the first programming language to obtain the first encrypted data.

In order to improve the security of data communication, this embodiment performs AES encryption. The AES encryption adopts a symmetric encryption algorithm. The data required for encryption (decryption) includes the data to be encrypted (decrypted), the key, and the vector offset, which is different from the one-way encryption. Compared with the encrypted MD5 algorithm, AES encryption has higher security and can meet the new security authentication requirements.

S103. The application terminal sends the first encrypted data to the server terminal.

In this embodiment, the application sends the first encrypted data to the server through a socket. Socket communication is one of the data transmission methods between application layers in the TCP/IP protocol model, which can realize application data communication between the client and the server.

S104. The server receives the first encrypted data and performs AES decryption through the second programming language to obtain the first decrypted data.

For example, the server is the management software set on the background server, which can prevent the application side from accessing the database of the background server, which can reduce the risk of database paralysis or loss of control caused by viruses or illegal operations, which is conducive to improving the security of the distribution automation system. sex. The communication between the application and the server is encrypted and decrypted by AES, which is beneficial to further improve the security of the communication.

S105, the server parses and verifies the first decrypted data by using the second programming language based on the request protocol.

The server and the application communicate based on the same communication interface protocol, which is easy to manage, and because the communication interface protocol stipulates the parameters, it provides a basis for realizing cross-language communication between the server and the application. In addition, after parsing the first decrypted data, the server needs to perform verification, which is beneficial to strengthen the security of the power distribution automation system. The verification of the first decrypted data by the server includes module name verification, function name verification and user login ID verification. Module name verification means that the server verifies whether it has the currently requested functional module based on the module name, and returns exception information if it does not have the currently requested functional module; function name verification means that the server verifies whether the current request has the current request based on the function name. The function function of , returns exception information if it does not have the function function of the current request; user login ID verification means that the server verifies whether the currently requested permission is sufficient according to the user login ID. Return exception information. The server verifies the first decrypted data, which is beneficial to improve the security of communication. The server returns the corresponding exception information according to different abnormal conditions, and can handle the abnormal response uniformly, which is convenient for management.

S106, after the verification is passed, the server accesses the database and obtains business data from the database.

In the process of accessing the database, AES encryption and decryption of the data, and verification of the request data are conducive to enhancing data security, and the use of a unified request protocol and verification of the request data is conducive to the standardization of business processes.

The communication process of the request information between the application and the server has been discussed above, and the processing process of the response information on the server is discussed below. Referring to FIG. 2, the front-end and back-end cross-language communication method based on AES encryption further includes steps S107-S109. in,

S107, the server organizes the business data into response data through the second programming language based on the response protocol;

S108. The server performs AES encryption on the response data by using the second programming language to obtain second encrypted data.

S109: The server returns the second encrypted data to the application.

After the server successfully obtains the corresponding business data from the database according to the request data, the server organizes the business data into response data through the Java programming language based on the above-mentioned response protocol, wherein the response data includes the mark of the successful response and the system time returned by the response and corresponding business data. The same as the processing process of the request information, in order to improve the security of data transmission, the server performs AES encryption on the response data, and the second encrypted data obtained after encryption is returned to the application side through the socket. It should be noted that the server returns the corresponding exception information if the verification fails. When returning exception information, the server also organizes the exception information into response data through the second programming language based on the response protocol. Different from the response data corresponding to the business data, the response data corresponding to the exception information includes the response failure flag, the response returned System time and corresponding business processing exception information. Then, the server encrypts the response data with AES and returns it to the application. In this way, unified management of abnormal response can be realized.

Next, the processing process of the response information on the application side is discussed. Please continue to refer to FIG. 2, the front-end and back-end cross-language communication method based on AES encryption further includes steps S110-S111. in,

S110, the application terminal receives the second encrypted data and performs AES decryption through the first programming language to obtain the second decrypted data;

S111. The application terminal parses and displays the second decrypted data through the first programming language based on the response protocol, so as to complete the response to the input request.

In the case where the server successfully obtains the service data, the second decrypted data obtained by the application through AES decryption includes the corresponding service data, but the service data needs to be parsed by the application through the JavaScript programming language based on the response protocol to obtain the applicable service data. business data in the application-side environment. The application side displays business data in a preset format, for example, in a tabular form or a graphical form.

In the case that the server verification fails, the second decrypted data obtained by the application through AES decryption includes corresponding abnormal information. Similarly, the application side obtains the exception information that matches the application side environment after parsing, and displays the exception information, such as issuing an alarm in the form of a pop-up box.
