废话不多说直接上代码：

  private void Form1_Load(object sender, EventArgs e){try{//更改设置浏览器语言CefSettings settings = new CefSettings();settings.Locale = "zh-CN";settings.AcceptLanguageList = "zh-CN";Cef.Initialize(settings);var re = new request();//接收和发送的http消息re.msg += Re_msg;re.msg2 += Re_msg2;    ... 这里是使用

private void Re_msg(string obj)
        {   //可打印Obj 内容即可看到 }
