我试图登录到我的大学网站，然后取消它的数据，（只是欢迎页面的源代码暂时）但im这让这个以下回溯..

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() 

这里是代码..

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) 

的帮助真的是appriciated ..

UPDATE

SO，这样做，
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

我以前的错误，我有答案。 导致该错误的原因很多。 这可能是由于连接的两端在保持连接期间不同意连接超时或不连接引起的。

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。
