【问题描述】：

我在使用新创建的 alexa 技能时遇到了一些问题。

在 Alexa 模拟器的文本框中键入请求总是返回“请求的技能响应有问题”。使用下面的输出 JSON。

{
  "body":{
    "version":"1.0",
    "response":{
      "outputSpeech":{
        "type":"PlainText",
        "text":"Hello i am here"
      },
      "card":{
        "type":"Simple",
        "title":"Welcome",
        "content":"Hello i am here"
      },
      "directives":[
        {
          "type":"Display.RenderTemplate",
          "template":{
            "type":"BodyTemplate2",
            "token":"",
            "backgroundImage":{
              "contentDescription":"Description for the background image",
              "sources":[
                {
                  "url":"URL for the background image - must be secure (https)",
                  "size":"x-small",
                  "widthPixels":0,
                  "heightPixels":0
                }
              ]
            },
            "image":{
              "contentDescription":"Description for the main image",
              "sources":[
                {
                  "url":"URL for the main image - must be secure (https)",
                  "size":"x-small",
                  "widthPixels":0,
                  "heightPixels":0
                }
              ]
            },
            "title":"Welcome",
            "textContent":{
              "primaryText":{
                "type":"RichText",
                "text":"Welcome"
              },
              "secondaryText":{
                "type":"RichText",
                "text":"Hello i am here"
              }
            },
            "backButton":"HIDDEN"
          }
        }
      ],
      "shouldEndSession":false
    },
    "sessionAttributes":{

    }
  }
}

但是，当我从请求中复制 JSON 输入并使用用户手册 JSON 进行测试时，它运行良好，但返回的 JSON 格式略有不同

知道问题出在哪里，谢谢。

【解决方案1】：

对于遇到此问题并遇到相同问题的任何人。如果响应包含 Display.RenderTemplate 指令，请确保在 Alexa 开发者控制台上启用了显示界面。

在您的技能上，从 Alexa 开发者控制台导航到 Interfaces 并确保 Display Interface 已启用。
