前言
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？”

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。
