coldfusion - 阵列单元冷聚变内的结构

Question

我一直在尝试创建一个数据结构，但遇到了困难。我正在尝试创建这样的数据结构:

{
    "vehicle": [
        {
            "inv_id": "123412",
            "year": "2013",
            "make": "Jeep",
            "model": "Grand Cherokee"
        },
        {
            "inv_id": "1224522",
            "year": "2013",
            "make": "Jeep",
            "model": "Grand Cherokee"
        }
    ]
}

这是我试过但没有成功的方法。

<cfset result["vehicle"] = []>
<cfoutput>
<cfloop query="qinv">
    #arrayAppend("result.vehicle,{})#
    <cfloop array="#result.vehicle#" index="i">
        #structInsert(result.vehicle[i], "inventory_id", qInv.inventory_id)#
        #structInsert(result.vehicle[i], "year", qInv.year)#
        #structInsert(result.vehicle[i], "make", qInv.make)#
        #structInsert(result.vehicle[i], "model", qInv.model)#
    </cfloop>
</cfloop>
</cfoutput>

这是抛出一个 coldfusion 错误，The value coldfusion.runtime.Struct cannot be converted to a number. 在第一个 structInsert 行。

有什么建议吗？

你不需要那个数组循环……想一想:你在循环什么？这是一个空数组。您需要做的就是将结构追加到数组中:

<cfset arrayAppend( result.vehicle,{
    "inventory_id" = qInv.inventory_id,
    "year" =  qInv.year,
    "make" = qInv.make,
    "model" = qInv.model
})>
