javascript - Bot 框架范围 beginDialogAction

问题描述

我在使用 beginDialogAction 方法来控制对话流时遇到了一些问题，希望得到一些建议。我对 JavaScript 很陌生。

我想做的是将关键字匹配到我的主对话框的上下文中。我的理解是 beginDialogAction 方法是最好的方法。我的问题是，一旦使用 beginDialogAction 触发了我的对话框，新对话框就会添加到堆栈中，并且 beginDialogAction 会继续侦听另一个匹配项。这意味着如果我的用户碰巧在流程中匹配我的触发词，它将改变谈话的主题。

我想要的是在开始 beginDialogAction 中指定的新对话框之前清除对话框堆栈，但我一直无法弄清楚到目前为止。任何建议将不胜感激！

代码：

var bot = new builder.UniversalBot(connector, function (session) {
    session.send("Hi, good to meet you! I'm here to help you request services. \n\n Please select an action from below.");
    session.beginDialog('main');
});
bot.dialog('main', [
    function(session){
    var msg = new builder.Message(session);
    msg.attachmentLayout(builder.AttachmentLayout.carousel)
    msg.attachments([
        new builder.HeroCard(session)
            .title("Request Design Services")
            .subtitle("I can send out a request for any design services you need, right from here!")
            .buttons([
                builder.CardAction.imBack(session, "I'd like to request design services.", "New Request")
            ]),
        new builder.HeroCard(session)
            .title("Project Finacials Request")
            .subtitle("I can pull finance information from any project within your organization.")
            .buttons([
                builder.CardAction.imBack(session, "I'd like to request financials.", "New Request")
            ])
    ]);
    session.send(msg)
}]).beginDialogAction('begindesign', 'design',{ matches: /design/i }).beginDialogAction('beginfinance', 'finance',{ matches: /financials/i });

bot.dialog('design', [
...
]);

bot.dialog('finance', [
...
]);

解决方案

您可以根据您的要求利用onSelectAction财产。说明可以参考源码：

/** * （可选）触发操作时调用的自定义处理程序。这使您可以 * 自定义操作的行为。例如，您可以在 * 新对话框启动之前清除对话框堆栈，从而更改默认行为，即仅将新 * 对话框推送到堆栈的末尾。* * 重要的是要注意这不是瀑布，next()如果您希望操作默认行为运行，您应该调用。*/

请考虑以下代码片段：

bot.dialog('mainMenu', [
    (session, args, next) => {
        builder.Prompts.text(session, 'Hi there! What can I do for you today?', {
            retryPrompt: 'Hi there! What can I do for you today?'
        });
    },
    (session, results) => {
        session.endConversation('Goodbye!');
    }
])
.beginDialogAction('sportsAction', 'Sports', {
    matches: /^sports$/i,
})
.beginDialogAction('cookingAction', 'Cooking', {
    matches: /^cooking$/i,
    onSelectAction: (session, args, next) => {
        session.clearDialogStack();
        next();
    }
})
bot.dialog('Sports', [
    (session, args, next) => {
        session.send(`current dialog length: ${session.sessionState.callstack.length}`);
        session.endDialog('Sports here');
    }
]);
bot.dialog('Cooking', [
    (session, args, next) => {
        session.send(`current dialog length: ${session.sessionState.callstack.length}`);
        session.endDialog('Cooking here');
    }
])
