如何在Windows上使用python Requests与Putty SOCKS代理?

Question

我设置了Putty来创建一个Socks代理，连接到一个服务器。现在我可以用Chrome和Firefox访问这个主机。

但是，当我用requests库时，出现了一个错误，似乎是和Putty的连接有问题。

我尝试设置HTTP_PROXY这个环境变量，也尝试过传递proxies参数。设置环境变量的方法出现了“解析失败”的错误，而使用proxies的方法则显示“最大重试次数超出”的错误。

设置环境变量时，调用 requests.get("http://10.122.116.17:8080/") 会出现这个错误：

requests.packages.urllib3.exceptions.LocationParseError: Failed to parse: Failed to parse: "localhost:1088"

传递proxies参数时，调用 requests.get("http://10.122.116.17:8080/",proxies=proxies) 会出现这个错误：

requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=1088): Max retries exceeded with url: http://10.122.116.17:8080/ (Caused by <class 'httplib.BadStatusLine'>: '')

我安装了Wireshark，并在我的代理服务器（216.255.67.119）上进行过滤。当我运行Firefox时，可以看到有流量发送到这个地址。但当我运行Python的Requests库时，似乎没有任何流量到达服务器。所以我怀疑requests中的代理机制没有连接到我的Putty会话。

有没有人能给我一些提示或建议，看看这里可能发生了什么？我已经谷歌搜索到手指都疼了！

提前谢谢大家！！！

这是我用Firefox访问服务器时的样子……
