您可以通过使用按钮（或您选择的实现）并通过网络聊天发送活动来完成此操作取消/中断组件对话框 of the 13.核心机器人示例（下面的示例使用 JS SDK，但在其他 SDK 中也可用）。
网络聊天：当。。。的时候button单击后，网络聊天将发送WEB_CHAT/SEND_ACTIVITY其中包括文本“重置”。

cancelAndHelpDialog.js：当机器人收到“重置”活动时，它会调用cancelAllDialogs(true)清除堆栈并将机器人返回到初始对话框。
async interrupt(innerDc) {
if (innerDc.context && innerDc.context.activity) {
const { activity } = innerDc.context;
if (activity.text) {
const text = activity.text;
const activityText = text.toLowerCase();
let message = '';
switch (activityText) {
case 'reset': {
message = 'Request approved: resetting dialog';
const resetMessage = MessageFactory.text(message, message, InputHints.IgnoringInput);
resetMessage.channelData = { action: 'dialog_reset' };
await innerDc.context.sendActivity(resetMessage);
return await innerDc.cancelAllDialogs(true);
}
case 'help':
case '?': {
message = 'Show help here';
await innerDc.context.sendActivity(message, message, InputHints.ExpectingInput);
return { status: DialogTurnStatus.waiting };
}
case 'cancel':
case 'quit': {
message = 'Cancelling...';
await innerDc.context.sendActivity(message, message, InputHints.IgnoringInput);
return await innerDc.beginDialog(EXIT_DIALOG);
}
}
}
}
}
这是相当简单的，可能需要一些“清理”来满足您的需求，包括显示对话框正在重新启动的某种响应。
希望得到帮助！
