如何使用带有Firebase功能的Google Actions和DiaglogflowApp处理不同的语言

我在Dialogflow代理中配置了多种语言。我无法弄清楚如何在我的firebase函数中检测请求的语言,以便用正确的语言回答。有没有一种标准方法来处理这个问题?我在https://github.com/actions-on-google/actions-on-google-nodejs

中看不到任何检测语言的功能

我希望能够做到这样的事情:

const app = new DialogflowApp({request: request, response: response});
if (app.getLang == 'en') { 
    \\ Do something in english 
}
else if (app.getLang == 'es') { 
    \\ Do something in spanish 
}

AoG GitHub上有Number Genie的公开示例,包括法语和英语。

在此示例中,他们为英语和法语语言环境定义JSON objects

{
"images": {
    "cold": {
        "url": "COLD.gif",
        "altText": "cold genie",
        "cardText": [
            "Freezing like an ice cave in Antarctica?",
            "I can't feel my face anymore",
            "Hurry, before I turn into an icicle"
        ]
    },
    ...

{
"images": {
    "cold": {
        "url": "COLD.gif",
        "altText": "Génie froid",
        "cardText": [
            "Je me gèle comme un glaçon en Antartique",
            "Je ne sens plus mon visage",
            "Dépêchez-vous avant que je ne me transforme en glaçon"
        ]
    },
    ...

然后有一个中心strings.js文件,它将为该语言环境提取正确的字符串。

const i18n = require("i18n");

i18n.configure({
   "directory": __dirname + "/locales",
   "objectNotation": true,
   "fallbacks": {
     "fr-FR": "fr",
     "fr-CA": "fr"
   }
});

const prompts = () => ({
"welcome": {
  "visual": {
    "elements": [
      [i18n.__("variants.greeting"), i18n.__("variants.invocation")],
      i18n.__("variants.invocationGuess"),
      i18n.__("images.intro")
    ],
    "suggestions": onlyNumberSuggestions
  }
},
...

然后用于map to each intent

  [Actions.GENERATE_ANSWER] () {
    this.data.answer = strings.getRandomNumber(strings.numbers.min, 

strings.numbers.max);         this.data.guessCount = 0;         this.data.fallbackCount = 0;         this.data.steamSoundCount = 0;         this.ask(strings.prompts.welcome,strings.numbers.min,strings.numbers.max);       }

通过从app.getUserLocale()方法获取语言环境来设置语言环境:

/**
 * Get the Dialogflow intent and handle it using the appropriate method
 */
run () {
  strings.setLocale(this.app.getUserLocale());
  /** @type {*} */
  const map = this;
  const action = this.app.getIntent();
  console.log(action);
  if (!action) {
    return this.app.ask(`I didn't hear a number. What's your guess?`);
  }
  map[action]();
}

这里肯定有很多,你不需要以完全相同的方式做到这一点。 app.getUserLocale()应该返回当前的区域设置,然后您可以以任何方式使用该区域设置来返回响应。
