Git Requests generally have no request body , Just focus on the request method and address .
test API Website ：

Two 、 Interface test process

1、 Get interface information ： Interface document or packet capture

Use of bag grabbing F12. Switch to network, Better choose Fetch/xhr.

Required interface information ：
The interface is in the process of passing to the server , Generate message , Message format ： That's ok + head + body , It is divided into request message （request） And return message （response）.

2.1.1 The composition of the request message

That's ok + head + body ：
The request message is divided into four elements ：
Request line ： HTTP Methods and URL Address .
Request header ： Generally, I don't pay much attention to . The only default concern is content-type Request format type .
Request body ：get Generally, there is no request body , Never mind ,post put Method , Parameters are usually placed in the request body .

The format of the request body eg：
Type 1 ：Content-Type: text/html; charset=utf-8
I understand it , This is like a package type of express delivery , If I take a popsicle and ask the courier to mail it , He would take a frozen box to hold , If I take a Book , He would take an ordinary box to hold .Content-Type It is equivalent to the packaging type .
Type 2 ：Content-Type:application/json

2.1.2 The composition of the return message

Generally, only the request body and status code are concerned .
Common status codes ：

	Category	The reason the phrase
1XX	Informational（ Informational status code ）	The accepted request is being processed
2XX	Success（ Success status code ）	The request is processed normally
3XX	Redirection（ Redirect the status code ）	Additional operations are required to complete the request
4XX	Client Error（ Client error status code ）	The server was unable to process the request
5XX	Server Error（ Server error status code ）	Server processing request error
