我在控制对话流的beginDialogAction方法上遇到了一些麻烦，希望提供一些建议。我刚接触JavaScript。
我想做的是将关键字的匹配范围限制到主对话框的上下文中。我的理解是beginDialogAction方法是执行此操作的最佳方法。我的问题是，一旦使用beginDialogAction触发了我的对话框，就会将新对话框添加到堆栈中，beginDialogAction会继续侦听另一个匹配项。这意味着，如果我的用户恰巧在流程中与我的触发词相匹配，它将改变对话的主题。
我想要清除的是在开始beginDialogAction中指定的新对话框之前清除对话框堆栈，但是我一直无法弄清楚到目前为止。任何建议将不胜感激！
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', [
...
]);
最佳答案
您可以根据需要使用onSelectAction属性。您可以参考the source code进行描述：
/ **
*（可选）自定义处理程序，只要触发该操作即可调用。这让你
*自定义动作的行为。例如，您可以在之前清除对话框堆栈
*将启动新对话框，更改默认行为，即仅推送新对话框
*对话到堆栈的末尾。
*
*请务必注意，这不是瀑布，如果您要调用next()
*希望动作默认行为运行。
* /
并且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');
}
])
