dialogflow-es - 格式错误的响应：由于语音响应为空，无法将 Dialogflow 响应解析为 AppResponse

Question

我在 Dialogflow 中使用 firebase 函数来实现 webhook。我正在使 webhook 成功，fulfillment status但它不起作用。我使用的是版本 1。当我在 Google Assistant 模拟器上对其进行测试时，它显示“应用程序没有响应”。

火力基地功能

const functions = require('firebase-functions');

exports.webhook = functions.https.onRequest((request, response) => {
    response.send({
        "google":{
           "richResponse":{
              "items":[
                 {
                    "simpleResponse":{
                       "textToSpeech":"Hey! Good to see you."
                    }
                 },
                 {
                    "mediaResponse":{
                       "mediaType":"AUDIO",
                       "mediaObjects":[
                          {
                             "name":"Exercises",
                             "description":"ex",
                             "largeImage":{
                                "url":"http://res.freestockphotos.biz/pictures/17/17903-balloons-pv.jpg",
                                "accessibilityText":"..."
                             },
                             "contentUrl":"https://theislam360.me:8080/hbd.mp3"
                          }
                       ]
                    }
                 }
              ],
              "suggestions":[
                 {
                    "title":"chips"
                 }
              ]
           }
        }
      }
   )
});`

{google...当我通过 GUI 手动将响应从自定义有效负载中复制粘贴到末尾时，它可以工作。而对于 webhook，它不起作用。

Answer 1

您没有在响应中使用正确的 JSON。通过将其放入 GUI 中的“自定义负载”部分，它会为您创建更大的 JSON 响应。该google对象需要位于dataDialogflow v1 或payloadDialogflow v2 的对象下。（如果你还没有切换到 v2 - 你应该立即这样做，因为 v1 将在大约一个月后关闭。）

所以你返回的应该看起来更像

{
  "payload": {
    "google": {
      ...
    }
  }
}
