Question

我正在处理smooch-bot-example，我已将其设置并上传到Heroku Git。我正在成功回复机器人。

我陷入了下面的情景。这是我的script.js文件（请参阅我的ADD_MOVIE块）

'use strict';

const Script = require('smooch-bot').Script;


var YtsHelper = require('./libs/YtsHelper.js');
const FirebaseHelper = require('./libs/FirebaseHelper.js');
var firebaseHelperObj = new FirebaseHelper();

module.exports = new Script({

processing: {
    prompt: (bot) => bot.say('Beep boop...'),
    receive: () => 'processing'
},

start: {
    receive: (bot) => {
        return bot.say('Hi! I\'m Smooch Bot!')
            .then(() => 'showUserMenu');
    }
},

showUserMenu: {

        prompt: (bot) => bot.say("Here are the areas I can help you out. %[Add Movie](postback:ADD_MOVIE) %[Serve Food](postback:SERVE_FOOD)"),
        receive: () => 'finish'
},

ADD_MOVIE : {

    prompt: (bot) => bot.say('Enter movie name or keywords you want to search please.'),
    receive: (bot) => {

        bot.say("Search in progress...")
        .then(() => {
            // Call API Here
            return bot.say("Search Finished.")
            .then(() => 'TEST_ROUT') // Go to TEST_ROUT
        });

    }

},

TEST_ROUT: {
        prompt: (bot) => bot.say("Test rout called"),
        receive: () => 'showUserMenu'
},


finish: {
    receive: (bot, message) => {
        return bot.getProp('name')
            .then((name) => bot.say(`Sorry ${name}, my creator didn't ` +
                    'teach me how to do anything else!'))
            .then(() => 'showUserMenu');
    }
}

});

我所做的是在我的ADD_MOVIE块中调用yts Api，成功响应后我想转到块TEST_ROUT但我在Heroku日志中得到这个。

2016-08-24T09:48:15.304174+00:00 app[web.1]: Undefined state
undefined for user 1c91f4b02bf493fc6e8c606a,reverting to default state 'start'

我被重定向到＆＃39; start＆＃39;块。这是我与Facebook的对话的Facebook Messenger截图

我在这里做错了什么？请记住，我必须调用API，一旦成功，我必须重定向TEST_ROUT块。

在应用解决方案后，我得到了奇怪的输出。见图：

在api结果

这是我现在更新的ADD_MOVIE块

TEST_ROUT: {
        prompt: (bot) => bot.say("Test rout called"),
        receive: () => 'showUserMenu'
},

ADD_MOVIE : {

    prompt: (bot) => bot.say('Enter movie name or keywords you want to search please.'),
    receive: (bot, message) => {
        const movie_name_searched = message.text;
        return bot.say('Search in progress...')
            .then(() => {
               return YtsHelper.getMoviesList(movie_name_searched,function(movies_array){

                    if(movies_array[0] != "ERROR_FOUND" && movies_array[0] != "NO_MOVIE_FOUND"){

                        var movies_postbacks = "";
                        for (var i = 0; i < movies_array.length ; i++){
                            movies_postbacks = movies_postbacks + " %["+movies_array[i]+"](postback:ADD_TO_FIREBASE)";
                        }

                        movies_postbacks = "Click any movie to add into firebase." + movies_postbacks;
                        bot.say(movies_postbacks);

                    }else{

                        if(movies_array[0] == "ERROR_FOUND"){
                            bot.say("ERROR Occured");
                        }else if(movies_array[0] == "NO_MOVIE_FOUND"){
                            bot.say("No movie found");   
                        }
                    }
                });
            })
            .then(() => "TEST_ROUT");
    }
},

您在return的{{1}}内遗漏了receive声明：

ADD_MOVIE

更新1

您的邮件显示不正常的原因是因为您对ADD_MOVIE : { prompt: (bot) => bot.say('Enter movie name or keywords you want to search please.'), receive: (bot) => { return bot.say("Search in progress...") .then(() => { return callMyApi(); }) .then(() => bot.say("Search Finished.")) .then(() => 'TEST_ROUT'); } }的调用使用的是回调，而不是promises。

如果你把你的电话包裹在一个Promise中，然后返回它，它应该有效：

getMoviesList

smooch-bot-example不切换到另一个块
