UWP Toast 工作正常，但图像(AdaptiveImage、ToastGenericHeroImage、ToastGenericAppLogo)不显示 [英] UWP Toast works, but images (AdaptiveImage, ToastGenericHeroImage, ToastGenericAppLogo) not displaying

问题描述

我的目标是 Windows 10，最新的操作系统版本.我从 Microsoft 自适应 Toast 示例中复制/粘贴了一些内容——包括路径.这是我的代码:

I am targeting Windows 10, latest OS build. I copy/pasted some stuff from the Microsoft adaptive toast examples--including the paths. Here's my code:

public void CreateToast(ToastViewModel model)
{
    ToastContent content = new ToastContent()
    {
        Launch = "app-defined-string",

        Visual = new ToastVisual()
        {
            BindingGeneric = new ToastBindingGeneric()
            {
                Children =
                {
                    new AdaptiveText()
                    {
                        Text = "Photo Share"
                    },

                    new AdaptiveText()
                    {
                        Text = "Andrew sent you a picture"
                    },

                    new AdaptiveText()
                    {
                        Text = "See it in full size!"
                    },

                    new AdaptiveImage()
                    {
                        Source = "https://unsplash.it/360/180?image=1043"
                    }
                },
                HeroImage = new ToastGenericHeroImage()
                {
                    Source = "https://unsplash.it/360/180?image=1043"
                },
                AppLogoOverride = new ToastGenericAppLogo()
                {
                    Source = "https://unsplash.it/64?image=883",
                    HintCrop = ToastGenericAppLogoCrop.Circle
                }
            }
        }
    };

    var toast = new ToastNotification(content.GetXml());
    toast.Failed += (o, args) =>
    {
        var message = args.ErrorCode;
    };

    ToastNotificationManager.CreateToastNotifier().Show(toast);
}

吐司显示，但图像不显示.有人有想法吗?

The toast displays, but the images do not. Anyone have an idea?

正如@AVK 建议的那样，我决定改用 XML 试一试；不幸的是，我得到了相同的行为——吐司表演，但没有图像.这是我的代码(尽管我对 XML 了解得更少，所以这段代码可能是错误的):

As @AVK suggested I decided to give it a shot using XML instead; unfortunately I get the same behavior -- toast shows, but no images. Here's my code for that (though admittedly I know even less about XML, so this code could be wrong-er):

var template = ToastTemplateType.ToastImageAndText02;
var xml = ToastNotificationManager.GetTemplateContent(template);
var elements = xml.GetElementsByTagName("text");
var text = xml.CreateTextNode(model.Title);
elements[0].AppendChild(text);
var images = xml.GetElementsByTagName("image");
var srcAttribute = xml.CreateAttribute("src");
srcAttribute.Value = "https://unsplash.it/64?image=883";
images[0].Attributes.SetNamedItem(srcAttribute);
var toast = new ToastNotification(xml);
ToastNotificationManager.CreateToastNotifier().Show(toast);

推荐答案

Http 图像仅在其清单中具有 Internet 功能的桌面桥应用程序中受支持.经典 Win32 应用程序不支持 http 图像；您必须将图像下载到本地应用数据并在本地引用.

Http images are only supported in Desktop Bridge apps that have the internet capability in their manifest. Classic Win32 apps do not support http images; you must download the image to your local app data and reference it locally.
