WebView应用程序显示空白页面

我创建了一个简单的现代UI应用程序,在应用程序加载时显示WebView上localhost站点的内容。当我调试它时,该应用程序工作正常。我已使用Visual Studio远程工具将其部署到另一台计算机上,并按预期工作。

但是,当我在Windows商店中发布它,然后从那里安装应用程序时,该页面为空白。商店中应用程序的名称名为Locked Browser Lite。

我很感激任何建议。

以下是代码:

        {
            this.InitializeComponent();
            this.Loaded += PageLoaded;
            this.Unloaded += PageUnloaded;

            wvMain.HorizontalAlignment = HorizontalAlignment.Stretch;
            wvMain.VerticalAlignment = VerticalAlignment.Stretch;

            //wvMain.Source = new Uri("http://localhost");
        }

        private void PageUnloaded(object sender, RoutedEventArgs e)
        {
            Window.Current.SizeChanged -= Window_SizeChanged;
        }

        private void PageLoaded(object sender, RoutedEventArgs e)
        {
            Window.Current.SizeChanged += Window_SizeChanged;

            Uri targeturi = new Uri("http://localhost");
            wvMain.Navigate(targeturi);
            //wvMain.Refresh();
        }

        private void Window_SizeChanged(object sender, Windows.UI.Core.WindowSizeChangedEventArgs e)
        {
            wvMain.HorizontalAlignment = HorizontalAlignment.Stretch;
            wvMain.VerticalAlignment = VerticalAlignment.Stretch;
        }

        private void btnReload_Click(object sender, RoutedEventArgs e)
        {
            PageLoaded(sender, e);
        }
    }
}

什么是'localhost'?

我尝试了你的应用程序,是的,它是空白的应用程序..因为你请求的网址,你请求你的应用程序导航到本地主机,而我的机器上没有本地服务器!

如果您有一些自定义HTML页面向用户显示,请尝试将其作为HTML文件脱机使用,并使用webview.NavigateToString(从文件中读取html)..
