CefSharp禁止弹出新窗体，在同一窗口打开链接，并且支持带type="POST" target="_blank"的链接

1、实现ILifeSpanHandler接口，代码如下：

using CefSharp;
 CefSharp.WinForms;
 System;
 System.Collections.Generic;
 System.Linq;
 System.Runtime.InteropServices;
 System.Text;
 System.Threading;
 System.Threading.Tasks;
 System.Windows.Forms;

namespace Mybrowser
{
    public class CefLifeSpanHandler : CefSharp.ILifeSpanHandler
    {
        public CefLifeSpanHandler()
        {

        }

        bool DoClose(IWebbrowser browserControl,CefSharp.Ibrowser browser)
        {
            if (browser.Isdisposed || browser.IsPopup)
            {
                return false;
            }

            true;
        }

        void OnAfterCreated(IWebbrowser browserControl,Ibrowser browser)
        {

        }

         OnBeforeClose(IWebbrowser browserControl,Ibrowser browser)
        {
        }

        bool OnBeforePopup(IWebbrowser browserControl,Ibrowser browser,IFrame frame,string targetUrl,1)">string targetFrameName,WindowOpendisposition targetdisposition,1)">bool userGesture,IWindowInfo windowInfo,1)">ref bool noJavascriptAccess,1)">out IWebbrowser newbrowser)
        {
            var chromiumWebbrowser = (ExtChromiumbrowser)browserControl;

            chromiumWebbrowser.Invoke(new Action(() =>
            {
                NewWindowEventArgs e = new NewWindowEventArgs(windowInfo);
                chromiumWebbrowser.OnNewWindow(e);
            }));

            newbrowser = null;
            ;
        }

    }
}

2、使用ILifeSpanHandler接口：

 System.Windows.Forms.Integration;

 ExtChromiumbrowser : ChromiumWebbrowser
    {
         ExtChromiumbrowser()
            : base()
        {
            this.LifeSpanHandler =  CefLifeSpanHandler();
            this.DownloadHandler = new DownloadHandler(this);
        }

        event EventHandler<NewWindowEventArgs> StartNewWindow;

         OnNewWindow(NewWindowEventArgs e)
        {
            if (StartNewWindow != )
            {
                StartNewWindow(,e);
            }
        }
    }
}

View Code

3、定义NewWindowEventArgs：

 NewWindowEventArgs : EventArgs
    {
        private IWindowInfo _windowInfo;
         IWindowInfo WindowInfo
        {
            get { return _windowInfo; }
            set { value = _windowInfo; }
        }

         NewWindowEventArgs(IWindowInfo windowInfo)
        {
            _windowInfo = windowInfo;
        }
    }
}

View Code

4、实现StartNewWindow：

private void Window_Loaded(object sender,RoutedEventArgs e)
{
    _browser = new ExtChromiumbrowser() { Dock = DockStyle.Fill };
    Bindbrowser(_browser);
    _browser.FrameLoadEnd += FrameLoadEnd;
    _browser.Load(_tokenUrl);
    host.Child = _browser;
}

 Bindbrowser(ExtChromiumbrowser browser)
{
    browser.StartNewWindow += (s,e) =>
    {
        var control =  System.Windows.Forms.Control();
        control.Dock = DockStyle.Fill;
        control.CreateControl();
        host.Child = control;
        control.Focus();

        e.WindowInfo.SetAsChild(control.Handle,0,int)host.ActualWidth,1)">int)host.ActualHeight);
    };
    browser.FrameLoadStart += (ss,ee) =>this.dispatcher.BeginInvoke(
        {
            (ss as ExtChromiumbrowser).Focus();
        }));
    };
}
