Python CannotSendRequest

Question

當我嘗試連接到Twitter時，我在oauth庫（Django socialauth）中收到一個CannotSendRequest。

Traceback: 
File "/Library/Python/2.6/site-packages/django/core/handlers/base.py" in get_response 
100.      response = callback(request, *callback_args, **callback_kwargs) 
File "/Users/me/webfaction/project/socialauth/views.py" in twitter_login

File "/Users/me/webfaction/project/socialauth/lib/oauthtwitter2.py" in fetch_request_token 
50.   return oauth.OAuthToken.from_string(oauth_response(oauth_request))

File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/httplib.py" in putrequest 
818.    raise CannotSendRequest() 

Exception Type: CannotSendRequest at /accounts/twitter_login/ 
Exception Value: 

這裏就是我創建的HTTP連接

def connection(): 
    try: 
     return connection._connection 
    except AttributeError: 
     connection._connection = httplib.HTTPSConnection(TWITTER_URL) 
    return connection._connection 

def oauth_response(req): 
    connection().request(req.http_method, req.to_url()) 
    return connection().getresponse().read() 

我已經搜查SO，發現這些鏈接，但我仍然不知道如何實施解決方案。我試過了，失敗了。任何幫助，將不勝感激。

When I use httplib for my OAUTH in Python, I always get "CannotSendRequest" and then "

The post you linked to說，當你重用拋出一個例外，它沒有到的GetResponse（）階段連接這個錯誤發生。

的確，connection.request("GET", "/") x 2會引發錯誤。

建議的解決方案是每次重新創建連接。那是你想要做的嗎？注意我對這個問題沒有意見，你只是問如何實現這些帖子上的內容。

如果是這樣，擺脫你connection()功能，始終做

connection = httplib.HTTPSConnection(TWITTER_URL) 
connection.request(req.http_method, req.to_url()) 
response = connection.getresponse().read() 
connection.close() 
return response
