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>

 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 + @"\Plugins\pepflashplayer.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(";, settings);

AI说的办法我没有试过，大家说它说得对吗？
