C# CEFSharp WPF开发桌面程序实现“同一网站多开”

孔乙己显出极高兴的样子，将两个指头的长指甲敲着柜台，点头说：“对呀，对呀！CEFSharp，你用过么？访问同一网址实现多开怎么实现？比如我有3个淘宝店，我想同时登录维护，就像传说中的指纹浏览器那样实现cookie和session隔离？”

前言

大家好，我是44岁的大龄程序员码农阿峰。好久没有开发过桌面软件了，记得还是在2018年开发过winform，这次用wpf实现了CEFSharp访问同一网址实现多开。官方的示例是访问不同的网站可以互不干扰。其实搜索引擎刚开始就帮我搜到了解决办法，不过是我当时没有意识到那些文字对我有帮助。几番趟坑，才得以解决。

1）关键实现

直接上代码：

 

/// <summary>         /// 初始化浏览器集合         /// </summary>         public void InitDictionary()         {             foreach (ChatUser user in LocalAccount)             {                 if (!Dict.ContainsKey(user.id))                 {                     #region 初始化ChromiumWebBrowser                     string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Cache\Cache_" + user.id.ToString());                     if (!Directory.Exists(path))                         Directory.CreateDirectory(path);                     var setting = new RequestContextSettings()                     {                         CachePath = path,                         PersistSessionCookies = true,                         PersistUserPreferences = true                     };                     var context = new RequestContext(setting);                     var cookieManager = context.GetCookieManager(null);                     //这样设置的cookie不是全局的，只有当前browser才能访问                     cookieManager.SetCookie("dxl.cn", new Cookie                     {                         Name = $"cookie{user.nickname}",                         Value = $"cookievalue{user.nickname}",                         Path = path                     });                     ChromiumWebBrowser chromeBrowser = new ChromiumWebBrowser()                     {                         Address = config.AppSettings.Settings["ChatUrl"].Value,                         RequestContext = context,                         MenuHandler = new NullMenuHandler(),                         LifeSpanHandler = new LifeSpanHandler(),                         Visibility = Visibility.Hidden                     };                     chromeBrowser.JavascriptObjectRepository.Settings.LegacyBindingEnabled = true;                     chromeBrowser.JavascriptObjectRepository.Register("bound", obj, false);                     #endregion                     obj.WebBrowserCallback += Obj_WebBrowserCallback;                     user.msgNum = null;                     chromeBrowser.LoadUrl(config.AppSettings.Settings["ChatUrl"].Value.Replace("login", "sso") + $"?token={user.token}");                     Dict.Add(user.id, chromeBrowser);                     mainWindow.MainGrid.Children.Add(chromeBrowser);                 }             }             AccountCountText = $"{LocalAccount.Count}/{config.AppSettings.Settings["MaxAccountCount"].Value}";             if (AccountPlusVisibility != Visibility.Visible)             {                 AccountPlusVisibility = Visibility.Hidden;             }         }

这是ViewModel的代码，下面是页面的

<Border Grid.Row="1" BorderBrush="Transparent" Background="#f0f0f0" BorderThickness="0" >                 <Grid x:Name="MainGrid"/>             </Border>

MainGrid就是多个ChromeBrowser的父容器，在切换账户的使用显示当前账户对应的ChromeBrowser其他的隐藏。

 public void ChangeBrowser(object xaml_obj)         {             var array = xaml_obj as object[];             if (array != null && array.Length == 2)             {                 Grid mainGrid = array[0] as Grid;                 ChatUser user = array[1] as ChatUser;                 if (user != null)                 {                     CurrentBrowser = Dict[user.id];                     foreach (var chromeBrowser in mainGrid.Children)                     {                         if (chromeBrowser == CurrentBrowser)                         {                             ((ChromiumWebBrowser)chromeBrowser).Visibility = Visibility.Visible;                         }                         else                         {                             ((ChromiumWebBrowser)chromeBrowser).Visibility = Visibility.Hidden;                         }                     }                 }             }         }

以上是按点击切换浏览器的代码。 

 

  /// <summary>         /// Cef 参数         /// </summary>         /// <returns></returns>         public static CefSettings GetCefSettings()         {             var settings = new CefSettings             {                 Locale = "zh-CN",                 AcceptLanguageList = "zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2",                 RemoteDebuggingPort = 8088,                 LogSeverity = LogSeverity.Disable,                 PersistSessionCookies = true,//Persistent Cookies会被保存在一个浏览器的一个子文件夹中                 UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36",                 IgnoreCertificateErrors = true,                 MultiThreadedMessageLoop = true,//让浏览器的消息循环在一个单独的线程中执行,建议设置成true,具体含义看看浏览器消息处理。                 WindowlessRenderingEnabled = true,//如果不开启好多用那种JSUI的控件的网站 都有问题                 CachePath = AppDomain.CurrentDomain.BaseDirectory + "/Cache",//缓存目录             };             settings.CefCommandLineArgs.Add("disable-application-cache", "1");//不要缓存             settings.CefCommandLineArgs.Add("disable-gpu", "1");//去掉gpu，否则chrome显示有问题             settings.CefCommandLineArgs.Add("enable-media-stream", "1"); //Enable WebRTC             settings.CefCommandLineArgs.Add("proxy-auto-detect", "0");             settings.CefCommandLineArgs.Add("no-proxy-server", "1");             settings.CefCommandLineArgs.Add("allow-running-insecure-content", "1");             //settings.CefCommandLineArgs.Add("ppapi-flash-version", "34.0.0.118"); //设置flash插件版本             //string flashFilePath = Application.StartupPath + @"Pluginspepflashplayer.dll";             //settings.CefCommandLineArgs.Add("ppapi-flash-path", flashFilePath);             //settings.CefCommandLineArgs.Add("enable-system-flash", "1");             settings.CefCommandLineArgs.Add("enable-npapi", "1");             settings.CefCommandLineArgs.Add("ppapi-out-of-process", "1");             settings.CefCommandLineArgs.Add("plugin-policy", "allow");              return settings;         }

 

以上是主程序进程启动时的初始化代码。

 

后记

WPF是数据驱动这真是比较香，做出来的程序对高DPI设备支持也好，可惜就是最后打包出来300多M老板接受不了，一番优化最后实现100M以下，奈何一搞C++的后生动作比我快，程序打包变态的小，程序性能貌似也比我的强。所以悲剧了，我最终二选一被PK下来，我的程序最终也是没有被使用。把关键代码分享出来，希望可以帮到有需求的人。

 

var settings = new CefSettings(); settings.CefCommandLineArgs.Add("disable-extensions", "1"); settings.CefCommandLineArgs.Add("disable-plugins", "1"); settings.CefCommandLineArgs.Add("disable-session-storage", "1"); settings.CefCommandLineArgs.Add("disable-web-security", "1"); settings.CefCommandLineArgs.Add("disable-pdf-extension", "1"); settings.CefCommandLineArgs.Add("disable-pdf-viewer", "1"); settings.CefCommandLineArgs.Add("disable-javascript", "1"); settings.CefCommandLineArgs.Add("disable-local-storage", "1"); settings.CefCommandLineArgs.Add("disable-webgl", "1"); settings.CefCommandLineArgs.Add("disable-geolocation", "1"); settings.CefCommandLineArgs.Add("disable-default-apps", "1"); settings.CefCommandLineArgs.Add("disable-remote-fonts", "1"); settings.CefCommandLineArgs.Add("disable-remote-images", "1"); settings.CefCommandLineArgs.Add("disable-remote-scripts", "1"); settings.CefCommandLineArgs.Add("disable-remote-video", "1"); settings.CefCommandLineArgs.Add("disable-remote-webaudio", "1");

var browser = new ChromiumWebBrowser("https://www.example.com", settings);

 

AI说的办法我没有试过，大家说它说得对吗？
