在集成cef3时，遇到一个设置代理的问题，cef3提供了两个设置代理的方式

继承CefApp类，通过实现接口OnBeforeCommandLineProcessing回调设置，
OnBeforeCommandLineProcessing回调中包含CefCommandLine命令行控制实例，调用CefCommandLine实例的AppendSwitchWithValue方法设置相关属性开关，如设置代理command_line->AppendSwitchWithValue("--proxy-server", "192.168.1.100:8000");，调用AppendSwitch方法设置不需要值的属性开关，如取消代理设置command_line->AppendSwitch("--no-proxy-server");
此方法设置的代理为全局属性，且初始化(CefInitialize)后该回调只会触发一次

继承CefRequestHandler类，通过实现接口OnBeforeBrowse回调设置，通过OnBeforeBrowse回调中的CefBrowser实例获取CefBrowserHost实例，再通过CefBrowserHost实例获取CefRequestContext实例，调用CefRequestContext实例的SetPreference方法设置属性值，设置代理方法如下：

CefRefPtr<CefDictionaryValue> dict = CefDictionaryValue::Create();
dict->SetString("mode", "fixed_servers");
dict->SetString("server", "192.168.1.100:8000");

CefRefPtr<CefValue> value = CefValue::Create();
value->SetDictionary(dict);
context->SetPreference("proxy", value, error);
1
2
3
4
5
6
7
如需取消代理设置，只需将SetPreference方法的第二个参数设为NULL，即：

context->SetPreference("proxy", NULL, error);
1
此方法设置的代理针对单独的CefBrowser实例，且每次加载完成都可以重新设置

chromium --proxy-server="socks5://127.0.0.1:1080"
Chromium和Chrome支持HTTP,HTTPS,SOCKS4和SOCK5代理。配置HTTPS代理：

chromium --proxy-server="https://proxy-ip:proxy-port"

  //command_line->AppendSwitch("no-proxy-server");
  command_line->AppendSwitchWithValue("--proxy-server", "127.0.0.1:19181");
  command_line->AppendSwitchWithValue("--proxy-server", "http://127.0.0.1:19181");
  command_line->AppendSwitchWithValue("--proxy-server", "https://127.0.0.1:19181");
  command_line->AppendSwitchWithValue("--proxy-server", "socks5://127.0.0.1:19181");
  command_line->AppendSwitchWithValue("proxy-server", "SOCKS5://127.0.0.1:19181");
