使用Beautifulsoup在html页面中找到CSRF令牌 [英] finding the CSRF token inside an html page using Beautifulsoup

问题描述

HTML看起来像这样

The HTML looks something like this

<input type="hidden" name="csrfToken" value="ajax:SOME_TOKEN"/>

我已经尝试了几种不同的方法，但是我一直遇到错误.我认为这种方式看起来正确，但显然不正确.

I've tried this a few different ways, but I keep getting an error. I thought this way looked right, but apparently not.

soup = BeautifulSoup(html_page)
soup.find('input', {'name':'csrfToken'})

我不断得到:

TypeError: 'expected string or buffer'

有什么想法吗?

推荐答案

这是从给定输入中提取CSRF令牌的一种方法:

This is one way of extracting the CSRF token from the given input:

from bs4 import BeautifulSoup

html = '<input type="hidden" name="csrfToken" value="ajax:SOME_TOKEN"/>'
soup = BeautifulSoup(html)

token = soup.find('input', {'name':'csrfToken'})['value']

print token

运行此命令的结果是:

ajax:SOME_TOKEN

通过查看您的示例，实际提取html元素似乎是正确的.可能是您未设置html_page或其他类型的类型(即不是字符串)吗?

By looking at your example, the actual extraction of the html element seems correct. Can it be that your html_page is not set or some other kind of type (i.e. not a string) ?
