WPF 实现 Chrome 内核的 Webbrowser
1. 使用 Nuget 添加 cefsharp.wpf 库
2. 窗口中使用

|
xmlns:chrome= "clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf" <chrome:ChromiumWebBrowser x:Name= "wbrReport" /> |
3. 打开指定的 URL

|
// 加载 URL this .wbrReport.Address = "www.baidu.com" ; |
4. Cefsharp.wpf 给 javascript 提供接口
1. 设置外部调用的对象

public class NtstJSObject { /// <summary> /// 提供给 Javascript 的对象 /// </summary> public static string ExportedJavascriptOjbectName = "ntst" ; private ReportWindow _reportWindow = null ; public NtstJSObject(ReportWindow reportWindow) { this ._reportWindow = reportWindow; } /// <summary> /// 提供给 Javascript 调用的 closeWindow 接口 /// </summary> public void closeWindow() { if ( this ._reportWindow != null ) { this ._reportWindow.CloseWindow( this ); } } } |
2. 窗体构造函数中绑定 js 对象

// 绑定 Javascript 调用对象 CefSharpSettings.WcfEnabled = true ; this .wbrReport.JavascriptObjectRepository.Settings.LegacyBindingEnabled = true ; this .wbrReport.JavascriptObjectRepository.Register(NtstJSObject.ExportedJavascriptOjbectName, new NtstJSObject( this ), false , BindingOptions.DefaultBinder); |
3. 窗口提供真正调用接口

/// <summary> /// Javascript 接口:closeWindow /// </summary> /// <param name="ntstJSObject"></param> public void CloseWindow(NtstJSObject ntstJSObject) { if ( this ._logger != null ) { this ._logger.WriteInformation( string .Format( "Javascript call to: {0}" , nameof(CloseWindow))); } this .Dispatcher.Invoke( new Action(() => { this .Close(); })); } |
4. Javascript 调用方式

ntst.closeWindow() |
