python模拟http请求--requests版本

发现了一个非常好用的第三方module：requests，模拟接口非常简单。

详细了解请移步：http://docs.python-requests.org/en/latest/

非常不错

#!coding:utf-8    相信这句大家都懂的，不解释

#导入需要的requests

import requests

#定义请求头

reqheaders={‘Content-type‘:‘application/x-www-form-urlencoded‘,  ‘Accept‘:‘text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8‘,  ‘Host‘:‘www.renren.com‘,  ‘Origin‘:‘http://zhichang.renren.com‘,  ‘Referer‘:‘http://zhichang.renren.com‘,  ‘User-Agent‘:‘Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1‘,}

#定义post的参数,requests模块，参数不用编码

reqdata={‘email‘:‘[email protected]‘,  ‘password‘:‘xxxx‘,  ‘autoLogin‘:‘on‘,  ‘origURL‘:‘http://zhichang.renren.com/?login_state=rr‘,  ‘domain‘:‘renren.com‘ }

#模拟post请求，不让自动重定向

res=requests.post("http://www.renren.com/PLogin.do",data=reqdata,headers=reqheaders,allow_redirects=False)

#模拟post请求，这个是自动重定向

#res=requests.post("http://www.renren.com/PLogin.do",data=reqdata,headers=reqheaders)

#打印服务器返回的状态

print(res.status_code)

#打印服务器返回的内容

print(res.content)

#打印重定向的URL地址

print(res.headers[‘Location‘])

#打印服务器返回的cookie

print(res.headers[‘Set-Cookie‘])

以下是程序的运行结果
