CefSharp 开发经验汇总

做过2个项目，使用CefSharp.Wpf。

引用CefSharp.Wpf

操作步骤

1. Nuget里面引用CefSharp.Wpf；
2. 解决方案平台换成x64，编译项目；

初始化

private ChromiumWebBrowser browser1;
browser1 = new ChromiumWebBrowser();
browser1.Address = “你的网址”;
备注：若网站使用的flash制作，需要到官方下载flashplayer先安装。

一些使用技巧

截图功能:

public static BitmapImage GetScreenSnapshot(FrameworkElement ui)
        {
            try
            {
                using (MemoryStream ms = new MemoryStream())
                {
                    RenderTargetBitmap bmp = new RenderTargetBitmap((int)ui.ActualWidth, (int)ui.ActualHeight, 96d, 96d, PixelFormats.Pbgra32);
                    bmp.Render(ui);
                    JpegBitmapEncoder encoder = new JpegBitmapEncoder();
                    encoder.Frames.Add(BitmapFrame.Create(bmp));
                    encoder.Save(ms);
                    ms.Position = 0;
                    BitmapImage bitmapImage = new BitmapImage();
                    bitmapImage.BeginInit();
                    bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
                    bitmapImage.StreamSource = ms;
                    bitmapImage.EndInit();
                    bitmapImage.Freeze();
                    return bitmapImage;
                }
            }
            catch
            {
                return null;
            }
        }

模拟鼠标点击和键盘输入（整站都采用flash版）：

private void Login(string userName, string password)
        {
            Task.Run(async delegate
            {
                IBrowserHost host = this.browser1.GetBrowserHost();
                //用户
                host.SendMouseClickEvent(442, 447, MouseButtonType.Left, false, 1, CefEventFlags.None);//按下鼠标左键
                await Task.Delay(100);
                host.SendMouseClickEvent(442, 447, MouseButtonType.Left, true, 1, CefEventFlags.None); //松开下鼠标左键
                await Task.Delay(3000);

                host.ImeCommitText(userName, null, 0);
                await Task.Delay(1000);
                //密码
                host.SendMouseClickEvent(442, 493, MouseButtonType.Left, false, 1, CefEventFlags.None);//按下鼠标左键
                await Task.Delay(100);
                host.SendMouseClickEvent(442, 493, MouseButtonType.Left, true, 1, CefEventFlags.None); //松开下鼠标左键
                await Task.Delay(3000);

                host.ImeCommitText(password, null, 0);
                await Task.Delay(3000);

                //登录
                host.SendMouseClickEvent(471, 548, MouseButtonType.Left, false, 1, CefEventFlags.None);//按下鼠标左键
                await Task.Delay(100);
                host.SendMouseClickEvent(471, 548, MouseButtonType.Left, true, 1, CefEventFlags.None); //松开下鼠标左键
                await Task.Delay(3000);//延迟3秒执行

                //重载浏览器（失败或掉线重启）
                //this.browser1.Reload();
            });
        }

备注：加入延迟以防操作过快而失败，html5版本直接使用js脚本即可。
