下文主要讲述如何利用python自带的库模拟http请求，为以后利用python做API测试做准备。
只讲述模拟http的过程，具体到自己用的时候，要以自己的应用为准做出适当的调整。
#!coding:utf-8 相信这句大家都懂的，不解释
#导入需要的python模块httplib，用来模拟提交http请求，详细的用法可见python帮助手册
import httplib
#导入需要的python模块urllib，用来对数据进行编码
import urllib
#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
reqdata={‘email‘:‘xxxx@xxx.com‘,
‘password‘:‘xxxx‘,
‘autoLogin‘:‘on‘,
‘origURL‘:‘http://zhichang.renren.com/?login_state=rr‘,
‘domain‘:‘renren.com‘
}
#对请求参数进行编码
data=urllib.urlencode(reqdata)
#利用httplib库模拟接口请求
#先连接到人人
conn=httplib.HTTPConnection(‘renren.com‘)
#提交登录的post请求
conn.request(‘POST‘, ‘/PLogin.do‘, data, reqheaders)
#获取服务器的返回
res=conn.getresponse()
#打印服务器返回的状态
print(res.status)
#以dictionary形式答应服务器返回的 response header
print(res.msg)
#打印服务器返回请求头中设置的cookie
print(res.getheader(‘Set-Cookie‘))
#以下为运行程序后的结果
