如何使用python请求获取uuid

标签: python http post login python-requests

我正在尝试使用python请求模块登录网页,但我想登录的网站上的Post数据包含一个uuid标记。

pass: ********
user: ********
uuid: ********

在大多数请求文档中,我已经彻底搜索过任何提及此内容的内容。这仅仅是出于程序的功能还是我忽视的东西。

这是我正在使用的代码。

import requests

url = 'www.website.com'

with requests.Session() as c:
     c.get(url)
     values = {'pass': 'passsword', 'user': 'username'}
     response = c.post(url, data=values)
     print response

您可以从源代码解析它:

In [29]: from bs4 import BeautifulSoup

In [30]: import re

In [31]: patt = re.compile("document.cplogin.uuid.value=\"(.*?)\"")

In [32]: with requests.Session() as s:
   ....:         page = s.get('http://myneu.neu.edu/cp/home/displaylogin').content
   ....:         soup = BeautifulSoup(page, "html.parser")
   ....:         script = soup.find("script", language="javascript1.1")
   ....:         uuid = patt.search(script.text).group(1)
   ....:     

In [33]: uuid
Out[33]: u'ff3e7ddd-0823-4f44-a003-0e68a9321e08'

如果您查看登录页面的来源,在脚本中使用 language =" javascript1.1" 属性,您可以看到uuid:

function login()
{
    setQueryAsCookie();
    document.cplogin.user.value=document.userid.user.value;
    document.cplogin.uuid.value="21fbc26a-3a3d-4802-ba4a-39a40aad881c";
    document.cplogin.submit();
}

因此,当您发布时,请将其与其余表单数据一起传递。

帖子网址似乎也是 https://myneu.neu.edu/cp/home/login ,所以:

from bs4 import BeautifulSoup
import re

patt = re.compile("document.cplogin.uuid.value=\"(.*?)\"")
data = {"user":"uname", "pass":"passw"}
post = "https://myneu.neu.edu/cp/home/login"

with requests.Session() as s:
    page = s.get('http://myneu.neu.edu/cp/home/displaylogin')
    soup = BeautifulSoup(page.content, "html.parser")
    script = soup.find("script", language="javascript1.1")
    uuid = patt.search(script.text).group(1)
    data["uuid"] = uuid
    resp = s.post(post, data=data)
