Question

我的代码

conn = __get_s3_connection(s3_values.get('accessKeyId'), s3_values.get('secretAccessKey'))
key = s3_values.get('proposal_key') + proposal_unique_id + s3_values.get('proposal_append_path')
request = urllib2.Request(conn.generate_url(s3_values.get('expires_in'), 'GET', bucket=s3_values.get('bucket'), key=key))
request.add_header('Accept-encoding', 'gzip')
response = urllib2.urlopen(request)

网址看起来像https://production.myorg.s3.amazonaws.com/key/document.xml.gz?Signature=signature%3D&Expires=1349462207&AWSAccessKeyId=accessId

此方法工作正常，直到1小时后，但是当我运行相同的程序时，它会抛出

    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 6] _ssl.c:503: TLS/SSL connection has been closed>

可能是什么原因？我该如何避免这种情况？
