When developing the interface, I used the Fiddler tool for testing. This tool can send get and post requests. If a post request is issued, the construction data format is as follows:
Header：
User-Agent: Fiddler
localhost: 8080
content-type: application/x-www-form-urlencoded;charset=utf-8
content-length: 0
Host: localhost:8080
post request data format:
beginPerion = 201604 & endPerion = 201704
However, if a json request is sent, the parameters cannot be received in the background, and this problem remains to be solved.
