python http post json

直接上代码吧

## python3

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import json, gzip
from urllib import request, parse

def REQ(url, params=None, headers=None):
    headers = headers or {}
    if params: # dict
        params = json.dumps(params) if headers['Content-Type'] and 'application/json' in headers['Content-Type'] else parse.urlencode(params)
        params = params.encode('utf-8')

    # 当 params 不为空，method 为 POST
    req = request.Request(url, params, headers)
    with request.urlopen(req, timeout=60) as page:
        res = page.read()

        if page.getheader('Content-Encoding') == 'gzip':
            res = gzip.decompress(res).decode('utf-8')
        else:
            res = res.decode('utf-8')

        if 'application/json' in page.getheader('Content-Type'):
            res = json.loads(res)

        return res

url = 'http://localhost/xxx'
d = {'a': 'aa', 'b': 'bb'}
headers = { 'Content-Type': 'application/json; charset=utf-8' }

res = REQ(url, d, headers)
print(res)

##python2:  

#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'] = '86945'
port = '3002'

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"}
