Coldfusion：api上的嵌套循环调用Array＆amp;结构

我的函数调用SendGrid API。它返回一个Array +结构。我正在编写一个返回CFQuery数据集的函数。

目标 我想将反序列化的数据对象传递给我的函数并获取查询数据集。

这是我的工作代码和输出：

<cfparam name="variables.ddata" default="#structnew()#">
<!--- API Call Code here --->
<cfset arr = DESerializeJSON(returnStruct.Filecontent) />
<cfdump var="#arr#">

CFdump on call

我的代码：

 <cfset arrayit(arrobj= arr) >
 <cfdump var="#variables.ddata#" >
 <cffunction name="arrayit" access="public" returntype="void">
    <cfargument name="arrobj" type="array"  required="yes">
    <cfset var arr=arguments.arrobj />
    <cfloop from="1" to =   "#arrayLen(arr)#" index="i">
       <cfif isValid("string", arr[i])>
          <cfset StructInsert(variables.ddata, i, arr[i]) />
       </cfif>
       <cfif isstruct(arr[i])>
          <cfset structit(structobj = arr[i]) />
       </cfif>
    </cfloop>
</cffunction>

<cffunction name="structit" access="public" returntype="void" output="yes">
   <cfargument name="structobj" type="any" required="yes">
   <cfset  stru = arguments.structobj />
   <cfloop collection="#stru#" item="S"> 
       <cfif isValid("string", stru[S])>
          <cfset StructInsert( variables.ddata, S, stru[S]) />
       </cfif>
       <cfif isarray(stru[S])>
           <cfset arrayit(arrobj = stru[S]) >
       </cfif>
   </cfloop>
</cffunction>

结果：

Result

当我在我的函数中添加这一行

时 
<cfif isstruct(stru[S])>
    <cfset variables.ddata   =  arrayit(arrobj = stru[S]) />
</cfif>

发生错误：

  

元素类型在作为一部分引用的CFML结构中未定义   表达。
第71行发生了错误。

2 个答案:

答案 0 :(得分：3)

您的UDF arrayit接受array类型的参数，但是当该条件为真时，则传递struct，错误。 即，

<cfif isStruct(stru[S])>

    <!--- This means stru[S] is a struct  --->
    <cfset variables.ddata = arrayit(arrobj = stru[S])>
    <!--- arrObj should be of type 'array' --->
</cfif>

所以，它应该是：

<cfif isStruct(stru[S])>
    <cfset variables.ddata = structit(structobj = stru[S])>
</cfif>

但是，此案例的错误将与您添加的错误不同。

<强>另外，

  • StructInsert()采用可选参数allowoverwrite，默认为false并根据文档：
  

如果密钥存在且allowoverwrite =＆＃34; False＆＃34;，ColdFusion抛出一个   异常。

我刚刚做到了！ :)只是想与你们分享我的项目，也希望它能帮助别人......

如果你们发现任何你认为我可以改进的东西请求分享。

特别感谢您对我的帖子的回复。 @Beginner＆amp; @Leigh
