Question

当我尝试连接到Twitter时，我在我的oauth库（Django socialauth）中收到了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)

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

这是我正在创建HTTP连接的地方

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()

我搜索了SO并找到了这些链接，但我仍然不确定如何实现该解决方案。我尝试过但都失败了。任何帮助将不胜感激。

httplib CannotSendRequest error in WSGI

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

The post you linked to表示当您重用已引发异常且未进入getresponse（）阶段的连接时会发生此错误。

确实，connection.request("GET", "/") x 2会引发错误。

建议的解决方案是每次都重新创建连接。那是你想做的吗？注意我对此事没有意见，你刚刚问过如何实现这些帖子上的内容。

如果是这样，请删除connection()功能并始终执行

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

Python CannotSendRequest
