我正在尝试找出如何更改PAC文件中打开的每个新URL的代理（总共10个代理）的方法，似乎找不到答案。
我最初的目标是在一天中每20分钟更换10个代理：
function FindProxyForURL(url, host) {
if (timeRange(00, 00, 00, 20)) return "PROXY 000.000.000.000:0000";
else if (timeRange(00, 20, 00, 40)) return "PROXY 000.000.000.000:0000";
else if (timeRange(00, 40, 01, 00)) return "PROXY 000.000.000.000:0000";
else if (timeRange(01, 00, 01, 20)) return "PROXY 000.000.000.000:0000";
else if (timeRange(01, 20, 01, 40)) return "PROXY 000.000.000.000:0000";

唯一的区别-实际的代理IP地址。我还使用此扩展名（https://github.com/orbitbot/chrome-extensions-examples/tree/master/proxy_configuration）每5秒重新加载错误的pac路径并重新加载默认的pac。尚未为我工作，我开始收到此错误消息：
ERR_TUNNEL_CONNECTION_FAILED
结果是扩展程序无法更新pac文件，因此我只能使用一个代理。
我正在寻找更简单的解决方案来解决此问题，我绝对不是程序员。
