模拟器在代码实验室中不“说话”：为Google Assistant构建操作(级别1)

Question

如果我遵循此code lab的说明，直到步骤4底部的“调试您的操作”，我会得到下面所示的奇怪行为。有人知道为什么吗？请注意，显示屏上显示了一个问题，但音频从未播放过(查看左侧以查看它是否存在)。我现在已经复制了两次，一次是昨天的，另一次是今天的(每次都是按照代码实验室的说明从头开始重新创建整个项目)。这似乎只是"phone“表面上的一个bug。切换到扬声器或Smart Display可以解决此问题。

​

以下是Response选项卡的内容：

    {
  "conversationToken": "[]",
  "finalResponse": {
    "richResponse": {
      "items": [
        {
          "simpleResponse": {
            "textToSpeech": "Welcome! What is your favorite color?"
          }
        }
      ]
    }
  },
  "responseMetadata": {
    "status": {
      "message": "Success (200)"
    },
    "queryMatchInfo": {
      "queryMatched": true,
      "intent": "44a0a46f-b4e3-4985-a7ea-59bb90ef3bb9"
    }
  }
}

和Debug选项卡：

    {
  "response": "Alright. Getting the test version of my test app.",
  "expectUserResponse": false,
  "conversationToken": "GidzaW11bG...",
  "audioResponse": "//NExAARiC...",

最后是我的意图，你可以看到它的id (在url栏中)，这表明它是匹配的意图。

我不明白为什么会发生这样的事情。感谢您的任何意见。

Answer 1

更新答案：

在使用模拟器与手机表面使用模拟器时，今天的模拟器体验与5月初在codelab拍摄的屏幕截图似乎不一致(你可以在那里看到日期)。

切换到不同的表面将使模拟器向您发出响应。但是，正如您可能注意到的，模拟器的"display“部分有正确的响应。在过去开发过动作之后，我不认为你在学习如何开发好的动作方面有什么问题。

老生常谈：

请取消选择“默认欢迎意图”的“将此意图设置为对话结束”切换。它位于Dialogflow控制台中意图UI的"Responses“部分下。

通常情况下，您可能希望仅在意图结束对话时才启用此开关。
