Python入門：模擬登錄（二）或注冊之requests處理帶token請求

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

首先說一下使用Python模擬登錄或注冊時，對於帶token的頁面怎么登錄注冊模擬的思路： 
1、對於帶token的頁面，需要先從最開始的頁面獲取合法token 
2、然后使用獲取到的合法token進行后續操作 
3、token一般存儲的地方有兩個： 
【一種是攜帶在cookie中】、【一種是在respose（頁面返回）的隱藏表單中】，獲取思路類似 
釋：header是針對服務端有各種限制或特定需求時使用的，一般服務器會進行類似如：X-Requested-With、Content-Length、User-Agent等的驗證，所以需要將其以字典的形勢發送給服務器

#reg.py
'''
此代碼只實現了注冊的第一步【手機發送驗證碼】,主要解決的獲取token
具體操作有：獲取頁面第一次請求時的重要信息，如：cookie與token
'''
import requests
#拼接url
host = "http://10.70.18.33:8083/"
url1 = host + "shopxx-mobile/register.jhtml"
#初始化url請求對象
r = requests.get(url1)
#獲取url請求對象中的有用信息，如token、cookies
token = r.cookies.items()[0][1]
cookies = r.cookies
#以下為測試，所獲取的token及cookie的格式
print(type(token))
print(token)
print(cookies)
print(r.headers)
print(r.url)
#手機號碼發送驗證碼的url拼接
url2 = host + "shopxx-mobile/register/send.jhtml"
#拼接header中的重要數據，如：token、cookie、User-Agent、Content-Length、X-Requested-With等，其中除token及cookie是通過上面的代碼獲取到的之外，其它的均可以通過firefox瀏覽器進行獲取
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": "18",
        "charset":"UTF-8",
        "cookie":"token=" + token
        }
#一般登錄注冊頁面均是post方式進行提交的，需要將post需要提交的數據（此處為需要發送驗證碼的手機號碼）進行組裝
data = {'mobile':'1851174****'}
#初始化post請求對象（需要傳入url、提交的數據、header）
s = requests.post(url2,data,headers=headers)
#打印返回結果
print(s)
print(s.status_code,s.text)

執行結果

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