python http post json

直接上代码吧

## python3

 4 import json, gzip
 5 from urllib import request, parse

 9     if params: # dict
10         params = json.dumps(params) if headers['Content-Type'] and 'application/json' in headers['Content-Type'] else parse.urlencode(params)
11         params = params.encode('utf-8')
12 
13     # 当 params 不为空，method 为 POST
14     req = request.Request(url, params, headers)
15     with request.urlopen(req, timeout=60) as page:
16         res = page.read()
17 
18         if page.getheader('Content-Encoding') == 'gzip':
19             res = gzip.decompress(res).decode('utf-8')
20         else:
21             res = res.decode('utf-8')
22

24             res = json.loads(res)
25 
26         return res

34 print res

dic = {'a': 'aa', 'b': 'bb'}

urllib.urlencode(dic)　　// dictionary 转成 url 中的参数: a=aa&b=bb

json.dumps(dic)　　// dictionary 转成 json: {"a":"aa", "b":"bb"}
