如何在Windows上將Python請求與Putty SOCKS代理一起使用？

Question

我已經設置了Putty以創建到服務器的Socks代理。 我可以使用Chrome和Firefox來訪問主機。 使用請求時，出現錯誤，似乎表明與Putty的連接有問題。 我嘗試設置HTTP_PROXY env變量，並嘗試傳遞proxies參數。 env變量方法產生“無法解析”錯誤，而代理方法產生超過最大重試次數。

設置env會在調用requests.get("http://10.122.116.17:8080/")時產生此錯誤

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

調用requests.get("http://10.122.116.17:8080/",proxies=proxies)時，傳遞proxies參數會產生此錯誤。

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

我已經安裝了Wireshark，並正在216.255.67.119的代理服務器上進行過濾。 運行Firefox時，我看到該地址的訪問量。 當我運行Python請求時，看不到服務器的任何流量。 因此，我懷疑請求中的代理機制沒有進入我的Putty會話。

有人對這里會發生什么有任何提示或建議嗎？ 我一直用谷歌搜索直到手指受傷！

提前致謝！！！

這是使用Firefox時服務器的外觀……

請求目前不支持SOCKS代理。 我們希望在底層的urllib3庫中獲得支持，但是沒有明確的時間表。 此問題已對此進行了跟蹤。

2016年編輯 ：從請求2.10開始，請求現在支持SOCKS代理。 您可以通過額外安裝socks來獲得支持： pip install requests[socks] 。
