postman is an interface debugging and testing tool that supports http protocol. Its main features are powerful functions, simple use and ease of use, often used for interface debugging of WebAPI.

This article mainly introduces how to use fuxa for WebAPI communication.At this stage, fuxa only supports the GET function, and the data packet is in Json format.We will use fuxa's GET function to obtain the datagram of postman.
