Question

我有以下JSON响应，我真的迷失了如何使用循环将其插入到ColdFusion查询中。

响应是这样的：

 {  
   "status":"OK",
   "data":{  
      "group_id":1522413460,
      "0":{  
         "id":"1522413460-1",
         "customid":"",
         "customid1":"",
         "customid2":"",
         "mobile":"0000000000",
         "status":"AWAITED-DLR"
      },
      "1":{  
         "id":"1522413460-2",
         "customid":null,
         "customid1":null,
         "customid2":null,
         "mobile":"0000000000",
         "status":"AWAITED-DLR"
      },
      "2":{  
         "id":"1522413460-3",
         "customid":null,
         "customid1":null,
         "customid2":null,
         "mobile":"0000000000",
         "status":"AWAITED-DLR"
      },
      "3":{  
         "id":"1522413460-4",
         "customid":null,
         "customid1":null,
         "customid2":null,
         "mobile":"",
         "status":"INV-NUMBER"
      }
   },
   "message":"Campaign of 4 numbers Submitted successfully."
}

我正在使用cflib中的jsondecode函数来解码JSON对嵌套结构的响应：

更新＃1：与DeserializeJSON，我得到以下屏幕截图。如果我循环遍历名为data的结果，如何嵌套内部结果？

Answer 1

JSON / CFML - Looping over an array of structs

我最近问过类似的事情。

看起来你有一系列结构。您可以像其他人描述的那样反序列化JSON并循环遍历它，如链接中所示。

这里有适合我的代码。我已经删除了一步，因为您收到的回复似乎并不包含编码字符。

<cfset requestBody = #(toString(getHttpRequestData().content)/>
<cfset ArrayOfStructs = deserializeJson(requestBody)>
<cfloop array="#ArrayOfStructs#" index="i">
<cfquery name="doodoodoo" datasource="CRM">
    INSERT INTO TimeAppTest
    (
        EmployeeID,
        lat,
        long,
        TimoStampo
        )
    VALUES
    (
        '#i.barcode#',
        '#i.lat#',
        '#i.long#',
        '#i.time#'

        )
</cfquery>
</cfloop>

JSON就是这样，解释了不同的变量名称。

{"barcode":"CSS1035","scannerID":"3e81b04aa521a05e","time":"2015-08-11 08:30:27.232","lat":32.4001579,"long":-110.0403455},
{"barcode":"CSS1959","scannerID":"3e81b04aa521a05e","time":"2015-08-11 08:30:29.366","lat":32.4001579,"long":-110.0403455},
{"barcode":"CSS1649","scannerID":"3e81b04aa521a05e","time":"2015-08-11 08:30:31.642","lat":32.4001579,"long":-110.0403455}

Answer 2

使用DeserializeJSON()转换为结构result。
使用result.data

<cfloop>

使用<cfquery>构造SQL INSERT语句，按<cfqueryparam>
