Python入门：模拟登录（二）或注册之requests处理带token请求

转自http://blog.csdn.net/foryouslgme/article/details/51822209

首先说一下使用Python模拟登录或注册时，对于带token的页面怎么登录注册模拟的思路： 
1、对于带token的页面，需要先从最开始的页面获取合法token 
2、然后使用获取到的合法token进行后续操作 
3、token一般存储的地方有两个： 
【一种是携带在cookie中】、【一种是在respose（页面返回）的隐藏表单中】，获取思路类似 
释：header是针对服务端有各种限制或特定需求时使用的，一般服务器会进行类似如：X-Requested-With、Content-Length、User-Agent等的验证，所以需要将其以字典的形势发送给服务器

 #reg.py
 '''
 此代码只实现了注册的第一步【手机发送验证码】,主要解决的获取token
 具体操作有：获取页面第一次请求时的重要信息，如：cookie与token
 '''
 import requests
 #拼接url
 host = "http://10.70.18.33:8083/"
 url1 = host + "shopxx-mobile/register.jhtml"
 #初始化url请求对象
 r = requests.get(url1)
 #获取url请求对象中的有用信息，如token、cookies
 token = r.cookies.items()[][]
 cookies = r.cookies
 #以下为测试，所获取的token及cookie的格式
 print(type(token))
 print(token)
 print(cookies)
 print(r.headers)
 print(r.url)
 #手机号码发送验证码的url拼接
 url2 = host + "shopxx-mobile/register/send.jhtml"
 #拼接header中的重要数据，如：token、cookie、User-Agent、Content-Length、X-Requested-With等，其中除token及cookie是通过上面的代码获取到的之外，其它的均可以通过firefox浏览器进行获取
 headers = {
         "token": token,
         "Host": "10.70.18.33:8083",
         "User-Agent":" Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:46.0) Gecko/20100101 Firefox/46.0",
         "Accept": "application/json, text/javascript, */*; q=0.01",
         "Accept-Language":"zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3",
         "Accept-Encoding": "gzip, deflate",
         "Content-Type":"application/x-www-form-urlencoded; charset=UTF-8",
         "X-Requested-With": "XMLHttpRequest",
         "Connection":"keep-alive",
         "Content-Length": "",
         "charset":"UTF-8",
         "cookie":"token=" + token
         }
 #一般登录注册页面均是post方式进行提交的，需要将post需要提交的数据（此处为需要发送验证码的手机号码）进行组装
 data = {'mobile':'1851174****'}
 #初始化post请求对象（需要传入url、提交的数据、header）
 s = requests.post(url2,data,headers=headers)
 #打印返回结果
 print(s)
 print(s.status_code,s.text)

执行结果

/Users/frankslg/PycharmProjects/cjb/mobile/regist.py
<class 'str'>
