Node.js 检查是否在自适应卡中填写了输入表单

您可以在自适应卡中使用输入表单。 但是，如何在不进入下一个对话框的情况下检查字段是否已填充。因此，在我单击submit按钮后，它应该检查字段是否已填写

代码：nodejs

---

示例：

自适应卡没有客户端验证，因此您必须从bot服务中检索值并在服务器上进行验证。如果字段没有按预期归档，那么您可以向用户发送一个响应，其中包含他们应该填写的内容。看一看这个机器人，看一个例子，在对话框中完成几个步骤，当提示输入时，发送一个空白响应，机器人将以友好的消息响应，要求您填写字段

源代码：

您可以在bot应用程序中验证输入并控制“注水”对话框。 例如

希望ut有帮助。

但是如果用户填写错误，您如何防止机器人再次发送卡片？

var bot = new builder.UniversalBot(connector, [(session,args,next) => {

    if (session.message && session.message.value) {
        // A Card's Submit Action obj was received
        if (processSubmitAction(session, session.message.value)) {
            next(session.message.value)
        }
        return;

    } 
        // Display Welcome card with Hotels and Flights search options
        var card = {
