alexa - Alexa 技能请求中的多个权限解决方案PerAuthority

Question

我一直在研究 Alexa 技能，到目前为止它运行良好，但今天我遇到了一个奇怪的问题。在其他技能中也可以看到类似的问题。问题是我在我的技能请求 JSON 的 resolutionsPerAuthority 中获得了多个权限。这些权限具有不同的状态码来匹配槽值。因此，我的代码遇到了困难，因为 resolutionsPerAuthority 应该只有一个对象。

我正在使用亚马逊官方文档中提供的代码来获取插槽值，并且由于这种情况而失败。还有其他人面临类似问题吗？有什么解决办法吗？

这是我的请求 JSON：

问题：我们无法检索 id 和与解析相关的各种数据。

原因：之前我们只有一个分辨率数组元素，我们将其引用为resolutionsPerAuthority[0]. 不过现在不止一个。

错误：其中一个分辨率项目显示Match和其他显示No Match。我们无法仅通过直接从resolutionsPerAuthority[0]

Anubhav 的解决方案：了解不一定只有分辨率数组的第一个元素才能显示Match代码。尝试 if else 或迭代该数组以定位哪个元素可以捕获您的请求。

//Check Status Code (Match/NoMatch) in 1st Element
console.log("Zero Code===>" +request.intent.slots.SlotName.resolutions.resolutionsPerAuthority[0].status.code); 

//Check Status Code (Match/NoMatch) in 2nd Element
console.log("One Code===>" +request.intent.slots.SlotName.resolutions.resolutionsPerAuthority[1].status.code); 

//Iterate and if Match condition is satisfied update the ID variable

if((request.intent.slots.SlotName.resolutions.resolutionsPerAuthority[0].status.code) === “ER_SUCCESS_MATCH")
 { 
      console.log("in If"); 
        try 
          { 
            var SlotID = request.intent.slots.SlotName.resolutions.resolutionsPerAuthority[0].values[0].value.id;                      console.log("SlotTwoID Collected"); 
           } 
        catch(Error) 
          {  
            console.log("In Catch”);
           }
 } 

else  
   { 
        console.log("in else"); 
          try 
              { 
               var SlotID = request.intent.slots.SlotName.resolutions.resolutionsPerAuthority[1].values[0].value.id;      console.log("SlotID Collected"); 
               } 
          catch(Error) 
             { 
             console.log("In Catch"); 
              }
     }

由于类似的问题，我无法检索插槽 ID
