Content-Type: application/x-www-form-urlencoded 请求样式

POST /app/a/update HTTP/1.1
Host: XXX.XXX.XXX.XXX:9999
Content-Type: application/x-www-form-urlencoded


bili=11&id1=e0e19646b23d11e799d100163e2ed483&endtime=2019-12-31+23%3A59%3A59&id2=cea53ef6d8f011e79ba100163e2ed483&id3=20190615170700000&max=99999&service_min=0&starttime=2019-06-15+00%3A00%3A00&type=0&status=1

其将参数进行urlencoded编码，并将其放入body中。在url中看不到参数。而get请求，将其放入到url中。

Content-Type: application/json 请求样式

POST /app/s/update HTTP/1.1
Host: XXX.XXX.XXX.XXX
Content-Type: application/json


{
    "bb": "12",
    "id1": "e0e19646b23d11e799d100163e2ed483",
    "endtime": "2019-12-31 23:59:59",
    "id2": "cea53ef6d8f011e79ba100163e2ed483",
    "id3": "20190615170700000",
    "max": "99999",
    "min": "100",
    "starttime": "2019-06-15 00:00:00",
    "type": "0"
}

将json字符串放body中。

Content-Type: multipart/form-data 请求样式

POST /app/s/update HTTP/1.1
Host: XXX.XXX.XXX.xxx
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW



Content-Disposition: form-data; name="username"
