如何在使用Dialogflow的Google Actions中使用字段和变量永久保存数据？

Question

我正在尝试建立一个时间表-谷歌-行动。动作应该是在呼叫时告诉特定日期的所有主体。问题是，如何将数据永久保存在我的设备上，以便随时访问数据？

我试图在fulfillment NODE.JS-File中声明字段，但根本不起作用。(我意识到这是一个非常愚蠢的想法，因为代码不能作为“程序员”工作，所以没有编译好的东西在后台运行)。我尝试的下一件事是谷歌开发人员网站(https://developers.google.com/actions/assistant/save-data#df_nodejs)上的->代码片段1

我对对话流中的Java-Script或Node.JS或Google Actions没有任何进一步的了解，但我的老师告诉我们开发一个应用程序时，不要给出任何关于那个主题的信息。

您可以在代码片段2中查看我的实现代码

代码段1

function simpleResponse(conv) {
  conv.user.storage.count = 1;
  conv.ask('When is your birthday?');
}

代码段2

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });
  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

 /*  FUNCTIONS  */ 
  function getSubjects(agent) {
    const date = agent.parameters.date;
    const dateIso = new Date(date);
    const weekDayInt = dateIso.getDay();
    var dayString = '';
    switch (weekDayInt){
      case 0: dayString='Sonntag'; 
        var output = agent.user.storage.sun.join(' ');
      break;
      case 1: dayString='Montag'; 
        var output = agent.user.storage.mon.join(' ');
      break;
      case 2: dayString='Dienstag'; 
        var output = agent.user.storage.tue.join(' ');
      break;

/更新/

我现在尝试了你的代码，但它根本不起作用。谷歌解释错误的一天没有任何改变的代码(我有点困惑)和字符串(主题)也不能保存。

如果你能再看一遍我的新实现代码，告诉我哪里出了问题，那就太好了。

Answer 1

您的主要问题是，在第一个代码片段中，它假定使用actions-on-google库而不是dialogflow-fulfillment库。

userStorage功能仅适用于谷歌上的操作，因此您需要将所有代码转换为使用actions-on-google而不是dialogflow-fulfillment。

下面是一个快速示例，说明如何调整代码以使用库。这不是一组完整的更改，但应该可以帮助您入门。

const functions = require('firebase-functions');
const {dialogflow, BasicCard, Suggestions} = require('actions-on-google');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

const app = dialogflow();

app.intent('Stundenplan', (conv, {date}) => {
  const dateIso = new Date(date);
  const weekDayInt = dateIso.getDay();
  let dayString = '';
  let output = '';
  switch (weekDayInt) {
    case 0:
      dayStrin = 'Sonntag';
      output = conv.user.storage.sun.join(' ');
      break;
    // ...
  }
  conv.ask('This message is from the Dialogflow Cloud Function for Firebase editor');
  conv.ask(new BasicCard({
    title: `Dein Studenplan für ${dayString}:`,
    text: `Du hast heute ${output}.`,
    buttonText: 'This is a button',
    buttonUrl: 'https://assistant.google.com/'
  }));
  conv.ask(new Suggestions('Stundenplan für heute', 'Stundenplan für morgen'))
})

exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
