在Microsoft BotBuilder NodeJS SDK中设置瀑布对话框的下一步

const { WaterfallDialog, DialogSet, DialogTurnStatus } = require('botbuilder-dialogs');

// 创建瀑布对话框
const waterfallDialog = new WaterfallDialog('waterfallDialog', [
    async function (stepContext) {
        await stepContext.context.sendActivity('这是第一步');
        return await stepContext.next(); // 进入下一步
    },
    async function (stepContext) {
        await stepContext.context.sendActivity('这是第二步');
        return await stepContext.next(); // 进入下一步
    },
    async function (stepContext) {
        await stepContext.context.sendActivity('这是最后一步');
        return await stepContext.endDialog(); // 结束对话
    }
]);

// 创建对话管理器
const dialogSet = new DialogSet();
dialogSet.add(waterfallDialog);

// 在Bot的逻辑中使用对话管理器
async function botLogic(turnContext) {
    const dialogContext = await dialogSet.createContext(turnContext);
    const results = await dialogContext.continueDialog();

    if (results.status === DialogTurnStatus.empty) {
        await dialogContext.beginDialog('waterfallDialog');
    }
}

// 注册Bot的逻辑
adapter.processActivity(async (turnContext) => {
    await botLogic(turnContext);
});
