在AdaptiveCard中，使用Action.OpenUrl，拥有mailto链接的邮件操作不再支持。为了解决这个问题，可以使用Action.Submit和microsoftTeams.openUrl，以便启动邮件应用程序并打开一个预先填好的电子邮件。

示例代码：

{

"type": "AdaptiveCard",

"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",

"version": "1.2",

"body": [

{

"type": "TextBlock",

"text": "请填写以下表格并点击下面的按钮提交表格。"

},

{

"type": "Input.Text",

"id": "name",

"placeholder": "请输入您的名称"

},

{

"type": "Input.Text",

"id": "email",

"placeholder": "请输入您的电子邮件"

},

{

"type": "ActionSet",

"actions": [

{

"type": "Action.Submit",

"title": "提交表格"

}

]

}

],

"actions": [

{

"type": "microsoftTeams.openUrl",

"title": "发送邮件",

"url": "mailto:example@example.com?subject=TestSubject&body=MaillContent"

}

]

}
