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 + @"\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("https://www.example.com", settings);
AI说的办法我没有试过,大家说它说得对吗?
