TypeError：類型'響應'的對象沒有len（）[BeautifulSoup]

Question

我試圖登錄到我的大學網站，然後取消它的數據，（只是歡迎頁面的源代碼暫時）但im這讓這個以下回溯..

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() 

這裏是代碼..

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) 

的幫助真的是appriciated ..

UPDATE

SO，這樣做，
soup = BeautifulSoup(opens.text, 'lxml')
print(soup)

給了我這個..

Answer 1

BeautifulSoup需要返回的內容，而不是完整的響應。嘗試使用opens.text：

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

Answer 2

我以前的錯誤，我有答案。 導致該錯誤的原因很多。 這可能是由於連接的兩端在保持連接期間不同意連接超時或不連接引起的。

要詳細檢查問題，可以使用Wireshark。

或者您可以重新請求或重新連接。
