python http post json

直接上代码吧

 #coding=utf-8
 import os
 import urllib
 import urllib2
 import re
 import cookielib
 import json

 headers = {}
 headers['Content-Type'] = 'application/json; charset=utf-8'

 values = {}
 values["uuid"] = 'XXXXX'
 values['uid'] = ''
 port = ''

 route = 'login'

 post_data = urllib.urlencode(values)
 j_data = json.dumps(values)
 print j_data

 def jsonPost(url):
     req = urllib2.Request(url, j_data, headers)
     page = urllib2.urlopen(req)
     res = page.read()
     page.close()
     return res

 res = jsonPost("http://127.0.0.1:%s/%s" % (port, route))
 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"}
