Python 請求中的大量“ConnectionRefusedError：[WinError 10061]”

Question

所以我知道下面有很多代碼需要查看，但我完全被難住了，因為我在使用 python 時從來沒有遇到過這樣的問題。

我希望使用請求模塊來幫助我加快一些基於 Web 的工作活動。 我根據開發人員的要求下載了 zipball 並運行“setup.py”將其安裝到“site-packages”目錄中。

我已經驗證所有內容確實在它應該在的地方，理論上我應該能夠導入它然后使用它，但是當我輸入任何代碼來發出新請求時，例如：
r = requests.get(' https://api.github.com/events ') 我得到了下面的大量錯誤，我一個字也聽不懂。

Answer 1

我在回答我自己的問題，因為我在 URLLIB3 和 Requests for Python 3.5 的文檔中做了更多的挖掘，發現根本問題是 WIN 錯誤 10061。

URLLIB3 和請求從 Internet Explorer 的默認代理設置派生其設置。

通過將我的 Internet Explorer 代理設置重置為空，它解決了我的所有問題。

出於某種原因，盡管我從未在這台機器上使用過 Internet Explorer，但除了下載 firefox 外，我使用的其他一些應用程序也必須更改了 IE 中的設置。 可能是windows防火牆。

希望將來出現的任何人都會看到這個問題並從我的錯誤中吸取教訓。

Answer 2

很明顯，您遇到了連接問題。 不知道更多，我猜這是由於代理問題。 如果是這樣，這里是使用requests模塊設置代理的stackoverflow 答案。

如果不是，1) 什么操作系統？，2) pip 的環境變量設置？ 3）企業網絡還是家庭？

Answer 3

確實，問題出在 Internet 設置中。 怎么修：

1. 點擊右上角的齒輪
2. 選擇一項“Internet 選項”
3. 轉到選項卡“連接”
4. 點擊“局域網設置”
5. 取消選中“使用代理服務器...”
