CEFsharp使用代理及切換

Posted 2020-11-22 feiyucha

常規方法：

var setting=new CefSetting();
setting.CefCommandLineArgs.add("proxy-server",ProxyAdd:Port);
Cef.Initialize(settings);

　　但是Cef.Initialize(settings)只能初始化一次  不過user-agant可以多次是修改

測試可用的：

        async private void SetProxy(ChromiumWebBrowser cwb, string Address)
        {
            await Cef.UIThreadTaskFactory.StartNew(delegate
            {
                var rc = cwb.GetBrowser().GetHost().RequestContext;
                var v = new Dictionary<string,object>();
                v["mode"] = "fixed_servers";
                v["server"] = Address;
                string error;
                bool success = rc.SetPreference("proxy", v, out error);
            });
        }

　　可以在Cef.Initialize(settings)初始化後調用如上方法即可完成切換
