Bot Framework V4 - 图像未显示在 Microsoft Teams 的自适应卡片中

Question

我刚刚开始使用 BotFramework。我正在尝试在 Microsoft Teams 中显示自适应卡片，并且正在使用从 https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/50.teams-messaging-extensions-search 下载的代码

我看到响应 JSON 中返回的图像 URL 是正确的，我可以将其粘贴到浏览器中，图像显示正常，但在卡片中，图像显示为“未定义”。我看到 Teams 将 URL 更改为 - https://urlp.asm.skype.com/v1/url/content?url=[original_url]

我尝试将 Azure Blob 防火墙设置更改为“允许所有网络”，并将我的应用程序域和 urlp.asm.skype.com 添加到 manifest.json 中的 validDomains[] 配置中，但我仍然有我的图片有问题。

我使用的 JSON 如下 - ${thumbnailurl} 包含缩略图的 url。
