python - 通过代理请求访问网站有时不起作用（http.client.RemoteDisconnected：远程结束关闭连接没有响应）

Question

我一直在尝试使用 requests 模块通过 python 中的代理访问网站（在我的示例中我正在访问 api.ipify.org，因为它应该打印代理的 ip）。我之前使用相同的程序测试过代理，它已经工作了。但有时当我随机运行它时，它会给我一个错误。这是我的代码：

import requests

proxies = {
 "http": "39.100.18.200:8080",
 "https": "39.100.18.200:8080",
}
r = requests.get("http://api.ipify.org/", proxies=proxies)
print(r.text)

它应该打印： 39.100.18.200 它以前有，但随机它会给我这个错误：
