我写了下面的WinUI 3代码。这段代码的目的是使用CoreWebView2.CookieManager.AddOrUpdateCookie(Cookie)设置一个cookie,但在初始化webview2时没有设置cookie。(我在WebView2中使用DevTools确认了这一点。)而且,应用程序从未崩溃。有什么解决办法吗?

MainWindow.xaml

    x:Class="WebView.MainWindow"

{
    public sealed partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();
            MyWebView.CoreWebView2Initialized += WebviewLoaded;
        }

        public async void WebviewLoaded(WebView2 sender, CoreWebView2InitializedEventArgs args)
        {
            await MyWebView.EnsureCoreWebView2Async();
                var Cookie = MyWebView.CoreWebView2.CookieManager.CreateCookie("testcookie", "value", "https://test.com", "/");
                Cookie.IsHttpOnly = true;
                Cookie.IsSecure = true;
                Cookie.Expires = (DateTime.Now.AddDays(10).Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
                Cookie.SameSite = CoreWebView2CookieSameSiteKind.None;
            MyWebView.CoreWebView2.CookieManager.AddOrUpdateCookie(Cookie);
        }
    }
}

我刷新了我的操作系统,再次运行这个应用程序,但结果是一样的。

我找到解决办法了。在调用CoreWebView2.CookieManager.AddOrUpdateCookie(Cookie)之前,WebView必须能够访问Cookie的站点。在本例中,webview的默认url是microsoft.com,因此我更改了cookie的域
之前
var Cookie = MyWebView.CoreWebView2.CookieManager.CreateCookie("testcookie", "value", "https://test.com", "/");
之后
var Cookie = MyWebView.CoreWebView2.CookieManager.CreateCookie("testcookie", "value", ".microsoft.com", "/");
