1. json格式的post请求
关键部分加粗显示了，主要是post数据的编码方式以及请求头的Content-type
#coding=utf8 import json import gzip import msgpack import urllib import urllib2 import tarfile def request(): try: url = "http://10.11.12.13/abc/def" values = {"a":1, "b":2, "c":3, "d":4} data = json.JSONEncoder().encode(values) print data user_agent = ‘Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)‘ headers = {‘User-Agent‘ : user_agent, ‘Content-type‘:"application/json"} req = urllib2.Request(url, data=data, headers=headers) res_data = urllib2.urlopen(req) res = res_data.read() print "response:" + str(len(res)) if res_data.getcode() == 200: return res except urllib2.HTTPError, err: print(err.code) print(err.read()) raise
相应的flask获取数据方式：
req_data = request.get_data() json_data = json.loads(req_data) a = json_data[‘a‘] b = json_data[‘b‘]
2. 浏览器的原生form表单格式，对应 Content-type：application/x-www-form-urlencoded
#coding=utf8 import json import gzip import msgpack import urllib import urllib2 import tarfile def request(): try: url = "http://10.11.12.13/abc/def" values = {"a":1, "b":2, "c":3, "d":4} data = urllib.urlencode(values) print data req = urllib2.Request(url, data) res_data = urllib2.urlopen(req) res = res_data.read() print "response:" + str(len(res)) if res_data.getcode() == 200: return res except urllib2.HTTPError, err: print(err.code) print(err.read()) raise
可以看到，主要区别是数据编码方式不同。
