Question

更新

我能够将下面的范围缩小到：

>>> import httplib
>>> h1 = httplib.HTTPSConnection('s3.amazonaws.com')
>>> h1.request ("GET", "/")
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 958, in request
    self._send_request(method, url, body, headers)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 992, in _send_request
    self.endheaders(body)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 954, in endheaders
    self._send_output(message_body)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 814, in _send_output
    self.send(msg)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 776, in send
    self.connect()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 1161, in connect
    self.sock = ssl.wrap_socket(sock, self.key_file, self.cert_file)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 382, in wrap_socket
    ciphers=ciphers)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 143, in __init__
    self.do_handshake()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 306, in do_handshake
    self._sslobj.do_handshake()
error: [Errno 60] Operation timed out

鉴于：

>>> h1 = httplib.HTTPSConnection('google.com')
>>> h1.request ("GET", "/")
>>> r1 = h1.getresponse()
>>> print  r1.status, r1.reason
301 Moved Permanently

什么是关于AWS的httplib.HTTPSConnection？

（我知道上面的请求不是正确且完整的AWS请求，但我简化它只是为了尝试从服务器获得响应。）

原始请求：

请帮助绝望的开发者。我已经按照所有说明安装和启用django-storages，并在我的应用程序中将文件上传到S3。（由于此应用程序旨在部署在Heroku上，我使用virtualenv来管理依赖项。）

对于本地开发，我已将所有凭据放在〜/ .bash_profile中：

export AWS_ACCESS_KEY_ID=xxxx
export AWS_SECRET_ACCESS_KEY=yyyy
export S3_BUCKET_NAME=zzzz

所以，很好，但接下来：

> python manage.py shell
>>> import boto
>>> conn = boto.connect_s3()
>>> conn.get_all_buckets()

生成这些调试消息并出现此错误：

我无法理解的是，使用相同的证书我可以在Mac上使用GUI浏览S3时连接没有任何问题。我可以列出所有的桶。我可以进入斗zzzz。我可以上传一个文件。我可以再次下载它。我可以删除它。一切都很好。但无论我通过Boto尝试什么，它都会超时而没有进一步的评论。

为什么boto在我的本地环境中超时？！

Answer 1

基于调试输出中的这一行：

boto: establishing HTTPS connection: host=s3.amazonaws.com, kwargs={'timeout': 2}

我假设您在boto配置文件中添加了类似的内容：

[Boto]
http_socket_timeout = 2

这是对的吗？如果是这样，如果将此超时增加到10秒或20秒会发生什么。你还有超时吗？

Answer 2

不幸的是，问题出现在我的家庭网络上！当我把笔记本电脑带到别处工作时，问题并没有重演。所以问题与Django，Boto，AWS，S3，SSL，Python或任何远程有趣的东西无关，而且与时代华纳有线电视的糟糕程度有关。你相信吗？！
