Hero Image 不会显示在 ConnectorCard 中

HeroImage wornt show in ConnectorCard

我正在尝试发送带有 Hero Image 标签的连接卡。

我遵循了 MessageCard Playground 中的示例 但即使完全复制示例,它们也不会显示。没有错误,卡片显示正常,除了主图。

我要发送的json

{
    "@type": "MessageCard",
    "@context": "http://schema.org/extensions",
    "summary": "Task 42",
    "title": "Task Done: \"Building the Super Computer\"",
    "sections": [
        {
            "activityTitle": "Mice of Earth",
            "activitySubtitle": "9/13/2016, 11:46am",
            "activityImage": "http://static.website.com/images/smallimage.jpg",
            "facts": [
                {
                    "name": "Team:",
                    "value": "Team-Poster"
                },
                {
                    "name": "Task #:",
                    "value": "42"
                }
            ],
            "text": "Build supercomputer to answer the ultimate question",
            "heroImage": {
                "image": "http://static.website.com/images/party-1644648_1920.jpg",
                "title": "This is the image's alternate text"
            },
        }
    ]
}

Outlook Actionable Messages documentation 也讨论了主图,但缺少示例。

是的,目前 Microsoft 团队不支持连接器卡的英雄图像。您可以按照此处的文档进行操作:https://msdn.microsoft.com/en-us/microsoft-teams/teams-bots-cards and https://msdn.microsoft.com/en-us/microsoft-teams/connectors,说明很清楚。
