Python调用http-post接口的实现方式

res = {'a':1, 'b':2}
headers = {'content-type': 'application/json'}
resp = requests.post('http:/xxx/xxx', json=res, headers=headers)

POST http://www.example.com HTTP/1.1    Content-Type:
application/x-www-form-urlencoded;charset=utf-8
title=test&sub%5B%5D=1&sub%5B%5D=2&sub%5B%5D=3

POST http://www.example.com HTTP/1.1
Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryrGKCBY7qhFd3TrwA
------WebKitFormBoundaryrGKCBY7qhFd3TrwA
Content-Disposition: form-data; name="text"
title
------WebKitFormBoundaryrGKCBY7qhFd3TrwA
Content-Disposition: form-data; name="file"; filename="chrome.png"
Content-Type: image/png
PNG ... content of chrome.png ... ------WebKitFormBoundaryrGKCBY7qhFd3TrwA--
