Coldfusion:api 调用数组和结构上的嵌套循环

Question

我的函数调用 SendGrid API。它返回一个数组 + 结构。我正在编写一个函数来返回一个 CFQuery 数据集。

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#">

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:



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>

出现错误:

Element type is undefined in a CFML structure referenced as part of an expression.
The error occurred on line 71.

   </cfif>
</cfloop>
</cffunction>

Answer 1

您的 UDF arrayit接受类型为 array 的参数但是当该条件为真时，则 struct正在通过，错误。
IE。，

<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，应该是:

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

但是，这种情况下的错误将与您添加的不同。

此外，

StructInsert() 接受一个可选参数 allowoverwrite默认情况下是 false并根据文档:

if key exists and allowoverwrite = "False", ColdFusion throws an exception.
