我试图为我的情况找到正确的答案，但似乎它可能还不存在。

在我目前的培训课程（非常初学者级别）中，我有一个练习可以从 url 获取一些天气 json 信息（在这种情况下是开放天气）。目前，这是我被教导这样做的唯一方法：

url = "http://api.openweathermap.org/data/2.5/weather?q="+city+"&appid="+api_key

request = requests.get(url)
json = request.json()
print(json)

我按照说明设置了“city”和“api_key”参数，并且在连接到我的个人家庭网络时能够成功运行我的代码并获取 json 信息。然而，当我在办公室或通过 VPN 连接到我的工作网络时，我得到了这堵神奇的墙：

事实/采取的行动的快速参考：-尝试通过命令将代理全局设置为所有 Python 实例set proxy...。- 不使用venv. --proxy...-在通过 Visual Studio Code 终端执行之前，尝试在命令末尾添加参数。- 在 Windows 10 企业版上。

我无法转到课程的下一个模块，因为我需要此代码才能工作，以便我知道如何在我必须做的下一组代码中修复错误。如果有很多话要说，我也很抱歉（我想我是一个菜鸟是有原因的），但我真的很感谢任何可以指导我的人。

感谢一位同事的帮助，我能够更好地解释Сергей Зайков引用的链接。毕竟这是一个代理问题。

在对代码进行调整后，我可以通过添加下面的行并更新request.get

http_proxy = "http://*REDACTED*:8080"

proxyDict = {"http" : http_proxy}

request = requests.get(url, proxies=proxyDict)

我现在能够按预期运行我的代码。
