Question

我试图登录我的大学网站，然后从中删除数据，（暂时只是欢迎页面的源代码）但是我现在得到这个跟踪追溯..

Traceback (most recent call last):
   File "C:/Users/HUNTER/PycharmProjects/Encryption/erp.py", line 16, in   <module>
   soup = BeautifulSoup(opens, 'lxml')
   File "C:\Users\HUNTER\AppData\Local\Programs\Python\Python35-32\lib\site-packages\bs4\__init__.py", line 192, in __init__
   elif len(markup) <= 256 and (
   TypeError: object of type 'Response' has no len()

这是代码..

 import requests
 from requests import session
 from bs4 import BeautifulSoup

 url = 'http://erp.college_name.edu/'

 r = requests.session()
 data = {

    'tbUserName': 'username',
    'tbPassword': 'password'

 } 

opens = r.post(url=url, data=data)
soup = BeautifulSoup(opens, 'lxml')
print(soup)

帮助确实非常适合..

更新

所以，做， soup = BeautifulSoup(opens.text, 'lxml')
print(soup)

给了我这个..

Answer 1

BeautifulSoup需要返回的内容，而不是完整的响应。尝试使用opens.text：

opens = r.post(url=url, data=data)
soup = BeautifulSoup(opens.text, 'lxml')
print(soup)

Answer 2

之前我有过这个错误，我得到了答案。导致该错误的原因很多。这可能是由于连接的双方不同意在保持连接期间连接是否超时。

要详细检查问题，可以使用Wireshark。

或者您可以重新请求或重新连接。
