在 Lex Chatbot AWS 中导入 json 文件时出错答案

【问题标题】：Error importing json file in Lex Chatbot AWS在 Lex Chatbot AWS 中导入 json 文件时出错
【发布时间】：2021-03-24 23:20:03
【问题描述】：

我正在尝试使用 Lex 构建一个聊天机器人来获取实例详细信息。我正在尝试使用 json 构建 Bot。当我导入 json 文件时，它说“请求中的 JSON 结构无效。检查 JSON 结构并再次尝试您的请求。” .. 尝试了几个代码和相同的问题. 我不认为问题出在代码上，但我错过了什么.. 或者请指导我使用 Json 文件创建一个 Bot。

谢谢

预计 Bot 应该使用上面提到的插槽、话语等代码创建......

但它说错误..

        "name": "Slot Name (provided by developer)"
      }
    ],
    "conclusionStatement": {
      "messages": [ ]

  {
    "name": "Intent 2",
    "version": "3",
    "fulfillmentActivity": {
      "type": "ReturnIntent"
    },
    "sampleUtterances": [
      "Utterance 1",
      "Utterance 2",
      "Utterance 3"
    ],
    "slots": [],
    "conclusionStatement": {
      "messages": [ ]
    }
  },

// repeat for all other intents

与您的情况不同，只有意图名称似乎在意图数组中。如果您将输入的 JSON 放入 JSON 格式化程序网站（我个人使用https://jsonformatter.org/），它将显示检测到 JSON 错误的哪一行。

【讨论】：

我尝试了几个脚本和相同的错误..任何建议请。
@itechworkerz 你能分享一下你正在尝试的脚本是什么样的吗？这样我就可以帮助调试你的 JSON。
我已经在我的原始帖子中分享了代码..（在问题中）。请指教。

【解决方案2】：

intent json 结构（要导入）应如下所述，如here 所述（注意元数据和资源元素）：

{
  "metadata": {
    "schemaVersion": "1.0",
    "importType": "LEX",
    "importFormat": "JSON"
  },
  "resource": {
    "description": "intent description",
    "rejectionStatement": {
      "messages": [
        {
          "contentType": "PlainText or SSML or CustomPayload",
          "content": "string"
        }
      ]
    },
    "name": "intent name",
    "version": "version number",
    "fulfillmentActivity": {
      "type": "ReturnIntent or CodeHook"
    },
    "sampleUtterances": [
      "string",
      "string"
    ],
    "slots": [
      {
        "name": "slot name",
        "description": "slot description",
        "slotConstraint": "Required or Optional",
        "slotType": "slot type",
        "valueElicitationPrompt": {
          "messages": [
            {
              "contentType": "PlainText or SSML or CustomPayload",
              "content": "string"
            }
          ],
          "maxAttempts": value
        },
        "priority": value,
        "sampleUtterances": []
      }
    ],
    "confirmationPrompt": {
      "messages": [
        {
          "contentType": "PlainText or SSML or CustomPayload",
          "content": "string"
        },
        {
          "contentType": "PlainText or SSML or CustomPayload",
          "content": "string"
        }
      ],
      "maxAttempts": value
    },
    "slotTypes": [
        List of slot type JSON structures.
        For more information, see Slot Type structure.
    ]
  }
}
