How to use middleware to implement: client encrypts request body -> server decrypts request body -> server encrypts response body -> client decrypts response body

When using middleware to implement request encryption and decryption, I encountered some problems: request middleware only works on the server side and cannot modify the request body before the client initiates the request. Function middleware can only modify the request header, not the request body.
