AttributeError:“\u socketobject”对象没有“set-tlsext-u host-name”属性

Question

在python中，在Ubuntu服务器上，我试图让requests库发出https请求，如下所示：

import requests
requests.post("https://example.com")

首先，我得到了以下信息：

/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.

在遵循此问题中的建议：InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately之后，我现在已将警告升级为以下错误：

AttributeError: '_socketobject' object has no attribute 'set_tlsext_host_name'

我该怎么解决？

Answer 1

我的解决办法如下：

sudo apt-get purge python-openssl
sudo pip install pyopenssl

Answer 2

这使得python能够为我开发Ubuntu 12.04.3lts。

sudo apt-get install python-dev python-pip build-essential libffi-dev
sudo -H pip install --upgrade pip setuptools && sudo -H pip install --upgrade pyopenssl

Answer 3

关于红帽：

sudo yum remove pyOpenSSL
sudo pip install pyopenssl
