Google操作无法解析JSON响应

Question

我一直在努力让一个助理应用程序做出正确的反应。

这个应用程序是用Google编写的(没有其他组件，如对话框或Converse.ai)。

该应用程序的动作包如下所示：

{
    "actions":[
       {
         "description": "Default Welcome Intent",
         "name": "MAIN",
         "fulfillment": {
            "conversationName": "ACTION_INTENT_MAIN"
          },
          "intent": {
             "name": "actions.intent.MAIN",
             "trigger": {
                 "queryPatterns": [
                    "talk to gactions integration"
                  ]
             }
          }
       }
    ],
    "conversations":{
        "ACTION_INTENT_MAIN": {
           "name": "ACTION_INTENT_MAIN",
           "url": "https://my.custom.end/point"
        }
    },
    "locate":"en"
}

这是我在https://my.custom.end/pont上收到的JSON请求

{
     "user": {
     "userId": "<a-user-id-sent-by-GOOG>",
     "locale": "en-US",
     "lastSeen": "2018-01-31T09:33:07Z"
   },
   "conversation": {
     "conversationId": "1517393479793",
     "type": "NEW"
   },
   "inputs": [
     {
       "intent": "actions.intent.MAIN",
       "rawInputs": [
         {
           "inputType": "KEYBOARD",
           "query": "Talk to Gactions Integration"
         }
       ]
     }
   ],
   "surface": {
     "capabilities": [
       {
         "name": "actions.capability.AUDIO_OUTPUT"
       },
       {
         "name": "actions.capability.SCREEN_OUTPUT"
       },
       {
         "name": "actions.capability.MEDIA_RESPONSE_AUDIO"
       },
       {
         "name": "actions.capability.WEB_BROWSER"
       }
     ]
   },
   "isInSandbox": true,
   "availableSurfaces": [
     {
       "capabilities": [
         {
           "name": "actions.capability.AUDIO_OUTPUT"
         },
         {
           "name": "actions.capability.SCREEN_OUTPUT"
         }
       ]
     }
   ]
 }

在模拟器上，我得到了这样的响应：API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: ": Cannot find field.".

我可以确认传入的请求已将google-actions-api-version设置为2。

这是Google仿真器上的动作的sharedDebugInfo部分：

[
    {
      "name": "ResponseValidation",
      "subDebugEntry": [
        {
          "debugInfo": "API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: \": Cannot find field.\".",
          "name": "UnparseableJsonResponse"
        }
      ]
    }
  ]

信息丰富的错误消息缺少无法找到的字段的名称。

这就是我所做的一切关于这里

Answer 1

这个问题似乎与您的响应JSON有关。正如您在文档中看到的那样，有关响应JSON。

"speech": "You're now talking to GActions Integration. ",
"displayText": "You're now talking to GActions Integration. "

以上是无效的参数。相反，您的响应JSON应该如下所示：

{
  "conversationToken": "{\"state\":null,\"data\":{}}",
  "expectUserResponse": true,
  "expectedInputs": [
    {
      "inputPrompt": {
        "noInputPrompts": [],
        "richInitialPrompt": {
          "items": [
            {
              "simpleResponse": {
                "textToSpeech": "You're now talking to GActions Integration",
                "displayText": "You're now talking to GActions Integration"
              }
            },
            {
              "basicCard": {
                "buttons": [
                  {
                    "title": "Some Reddit to chill",
                    "openUrlAction": {
                      "url": "https://www.reddit.com"
                    }
                  }
                ],
                "formattedText": "Here's some simp-wave to relax and chill out to",
                "image": {
                  "url": "http://tracks.arte.tv/sites/default/files/styles/jscrop_1007x566/public/c_simpsons_2.jpg?itok=INzKpsvK",
                  "accessibilityText": "A World of Simpsonwave"
                },
                "title": "A World of Simpsonwave",
                "imageDisplayOptions": "CROPPED"
              }
            }
          ],
          "suggestions": []
        }
      },
      "possibleIntents": [
        {
          "intent": "actions.intent.TEXT"
        }
      ]
    }
  ],
  "resetUserStorage": false,
  "userStorage": "{}",
  "finalResponse": null,
  "isInSandbox": true,
  "customPushMessage": null
}

Answer 2

如果使用nodejs，请编辑，检查来自google函数的响应是否正确json，以及服务器是否回答正确的json。也许它改变了格式等等？

尝试使用action.json样式，就像第一个样式一样。和更重要的问题是，您对请求的响应如何？尝试使用下面最后一段代码创建的json样式。

{
  "locale": "en",
  "actions": [
    {
      "name": "text",
      "intent": {
        "name": "actions.intent.TEXT",
        "trigger": {
          "queryPatterns": [
            "some text"
          ]
        }
      },
      "fulfillment": {
        "conversationName": "conv name"
      }
    },
    {
      "description": "Default Welcome Intent",
      "name": "MAIN",
      "fulfillment": {
        "conversationName": "conv name"
      },
      "intent": {
        "name": "actions.intent.MAIN",
        "trigger": {
          "queryPatterns": [
            "open my test app",
            "open hi fish"
          ]
        }
      }
    }
  ],
  "types": [],
  "conversations": {
    "conv name": {
      "name": "conv name",
      "url": "https://yourendpoint.com/something",
      "fulfillmentApiVersion": 2,
      "in_dialog_intents": [
        {
          "name": "actions.intent.NO_INPUT"
        },
      ]
    }
  }
}

这里是一个创建有效响应的函数：

/**
message = string
slots = array
state = object
**/

    function answerWithMessage(message,slots,state){   
           let display = message.replace(/<[^>]*>/g, '');   
           let voicemessage = message.toLowerCase();

          let jsonResponse = {
            conversationToken: JSON.stringify(state),
            expectUserResponse: true,
            expectedInputs: [
              {
                inputPrompt: {
                  richInitialPrompt: {
                    items: [
                      {
                        simpleResponse: {
                          ssml: voicemessage,
                          displayText: display,
                        },
                      }
                    ],
                  }
                },
                possibleIntents: [
                  {
                    intent: "actions.intent.TEXT"
                  }
                ],
               speechBiasingHints: slots
              }
            ]   
         };   
       return JSON.stringify(jsonResponse,null, 4); 
    }

下面是一个例子，比如google：https://github.com/haukedau/googleActionsInit，但是答案并不完全正确，但是它会做同样的工作，上面的响应消息样式会更好。

Answer 3

嗨，我想你的问题是你只需要调用一个对象

    "inputPrompt": { 

和一个数组，但两者处于相同的位置，请看下面的解释。

    "noInputPrompts": [],

我希望我能帮你。
