firebase - Actions on Google 以 "Sorry, I didn' 响应，但未得到任何响应。”

Question

我正在关注此代码实验室 Facts about You: Build a conversational app for the Google Assistant

我让它工作了一次，但一定是做错了什么，因为现在全部。为了 100% 清楚，我已经删除了我电脑上的所有内容，从 Git 下载了代码，再次删除了操作控制台中的项目，删除了 api.ai 中的项目。这是全新安装的结果。 我没有更改代码实验室中的任何内容。

"Sorry, I didn't get any response."

请求似乎正确发送

来自 Action 测试:

{
  "conversationToken": "CiZDIzU5Ym...",
  "debugLevel": 1,
  "inputType": "KEYBOARD",
  "locale": "en-US",
  "mockLocation": {
    "city": "Mountain View",
    "coordinates": {
      "latitude": 37.421980615353675,
      "longitude": -122.08419799804688
    },
    "formattedAddress": "Googleplex, Mountain View, CA 94043, United States",
    "zipCode": "94043"
  },
  "query": "tell me about cats",
  "surface": "GOOGLE_HOME"
}

在火力基地收到

 [{"name":"actions.capability.AUDIO_OUTPUT"}]},"inputs":[{"rawInputs":[{"query":"tell me about cats","inputType":"VOICE"}],"arguments":[{"rawText":"tell me about cats","textValue":"tell me about cats","name":"text"}],"intent":"actions.intent.TEXT"}],"user":{"locale":"en-US","userId":"AETml1RzwqyijfbawqjZkRSXz-P1"},"device":{},"conversation":{"conversationId":"1504878811393","type":"ACTIVE","conversationToken":"[\"_actions_on_google_\",\"choose_fact-followup\"]"}}},"id":"3b97e239-346f-49a2-a106-96cfb6f69e92","timestamp":"2017-09-08T13:58:29.99Z","lang":"en","result":{"source":"agent","resolvedQuery":"tell me about cats","speech":"","action":"tell.cat.fact","actionIncomplete":false,"parameters":{},"contexts":[{"name":"_actions_on_google_","parameters":{"category.original":"headquarters","category":"headquarters","facts":{"content":{"headquarters":["Google has over 10 fitness facilities in its main campus."],"history":["Google was founded in 1998.","Google was founded by Larry Page and Sergey Brin.","Google went public in 2004.","Google has more than 70 offices in more than 40 countries."]}}},"lifespan":98},{"name":"actions_capability_audio_output","parameters":{},"lifespan":0},{"name":"google_assistant_input_type_voice","parameters":{},"lifespan":0},{"name":"choose_cats-followup","parameters":{},"lifespan":2}],"metadata":{"intentId":"14df3938-3776-477c-811c-d1758ecd15cb","webhookUsed":"true","webhookForSlotFillingUsed":"false","nluResponseTime":19,"intentName":"choose_cats"},"fulfillment":{"speech":"","messages":[{"type":0,"speech":""}]},"score":1},"status":{"code":200,"errorType":"success"},"sessionId":"1504878811393"}

对 Action 的响应

{
  "audioResponse": "//NExAARAA...",
  "conversationToken": "CiZDIzU5Ym...",
  "expectUserResponse": true,
  "response": "Sorry, I didn't get any response.",
  "visualResponse": {
    "visualElements": []
  }
}

我一定是遗漏了什么。 Firebase 正在接收请求，只是没有正确响应。

如果您的网络 Hook 未向助手提供响应，则会出现该错误。云函数触发或超时，未返回JSON给助手解析。检查云函数的输出是什么，并根据 API.AI 网络 Hook 格式检查它 https://developers.google.com/actions/reference/v1/apiai-webhook

它应该看起来像这样:

{
  "speech": "...",  // ASCII characters only
  "displayText": "...",
  "data": {
  "google": {
      "expect_user_response": true,
      "is_ssml": true,
      "permissions_request": {
         "opt_context": "...",
         "permissions": [
            "NAME",
            "DEVICE_COARSE_LOCATION",
            "DEVICE_PRECISE_LOCATION"
          ]
      }
    }
    },
   "contextOut": [...],
}
