使用云功能仿真器在本地测试Dialogflow的实现

是否可以使用云功能仿真器在本地测试Dialogflow实现Webhook，如果可以，我应该如何格式化请求？

我已经阅读了所有可以找到的文档，包括位于https://firebase.google.com/docs/functions/local-emulator的指南，并且特别有趣的是之前的这个问题似乎也遇到了类似的问题：在本地对Google Dialogflow进行单元测试操作

我可以使用函数外壳程序来调用实现功能，但是无论我如何尝试格式化主体，我似乎都只能触发后备意图或错误捕获意图。

我可以在Google模拟器上的操作上验证，当给定输入“ hello”时，我的webhook成功响应了默认的欢迎意图，但是当使用相同的请求JSON数据作为对我的函数的本地输入时，我将定向到回退意图。

是因为函数仿真器无法在本地执行适当的意图匹配，因此总是触发后备意图，还是我只是没有正确格式化请求？任何帮助将不胜感激！

这是我正在使用的调用格式，以及来自shell的响应：

firebase > fulfillment({method: 'POST',json: true,body: 
require("project/collabrec/testData.json")});
Sent request to function.
firebase > info: User function triggered, starting execution
info: Fallback intent triggered.
info: Execution took 15 ms, user function completed successfully

RESPONSE RECEIVED FROM FUNCTION: 200, {
  "payload": {
    "google": {
      "expectUserResponse": true,
      "richResponse": {
        "items": [
          {
            "simpleResponse": {
              "textToSpeech": "I didn't quite catch that. Could you say that again?"
            }
          }
        ]
      }
    }
  }
}

这是testData.json的内容：

{
  "user": {
    "userId": "ABwppHFR0lfRsG_UM3NkvAptIkD2iUpIUNxFt-ia05PFuPajV6kRQKXu_H_ECMMe0lP_WcCsK64sH2MEIg8eqA",

          "query": "hello"
        }
      ],
      "arguments": [
        {
          "name": "text",
          "rawText": "hello",
          "textValue": "hello"
        }
      ]
    }
  ],
  "surface": {
    "capabilities": [
      {
        "name": "actions.capability.MEDIA_RESPONSE_AUDIO"
      },
      {
        "name": "actions.capability.SCREEN_OUTPUT"
      },
      {
        "name": "actions.capability.AUDIO_OUTPUT"
      },
      {
        "name": "actions.capability.WEB_BROWSER"
      }
    ]
  },
  "isInSandbox": true,
  "availableSurfaces": [
    {
      "capabilities": [
        {
          "name": "actions.capability.SCREEN_OUTPUT"
        },
        {
          "name": "actions.capability.AUDIO_OUTPUT"
        },
        {
          "name": "actions.capability.WEB_BROWSER"
        }
      ]
    }
  ],
  "requestType": "SIMULATOR"
}

这是我的云函数webhook：

const {dialogflow, Image} = require('actions-on-google');
const admin = require('firebase-admin');
const functions = require('firebase-functions');
const app = dialogflow();


app.catch((conv, error) => {
  console.log("Error intent triggered.")
  console.error(error);
  conv.ask('Sorry, I ran into an error. Please try that again.');
});

app.fallback((conv) => {
  console.log("Fallback intent triggered.")
  conv.ask("I didn't quite catch that. Could you say that again?");
})

app.intent('Default Welcome Intent', (conv) => {
  console.log("Welcome intent triggered.")
    conv.ask("Welcome!!");
});

exports.fulfillment = functions.region('europe-west1').https.onRequest(app);

使用Node v8.1.4和软件包版本：
