Front-end and back-end cross-language communication method and system based on AES encryption

The invention discloses a front-end and back-end cross-language communication method and system based on AES encryption, and the method comprises the steps: enabling an application end to respond to an input request of a user, and organizing request data through a first programming language based on a request protocol; the application end performs AES encryption on the request data through a first programming language to obtain first encrypted data; the application side sends the first encrypted data to the server side; the server receives the first encrypted data and performs AES decryption through a second programming language to obtain first decrypted data; the server analyzes and verifies the first decrypted data through a second programming language based on the request protocol; and after the verification is passed, the server accesses the database and obtains the business data from the database. In the process of accessing the database, AES encryption and decryption are performed on the data, and the r
