python模拟登录或注册之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()[0][1]
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",

"X-Requested-With": "XMLHttpRequest",
"Connection":"keep-alive",
"Content-Length": "18",
"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)
