如何解析JSON响应并插入Query
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？

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。
编辑只是为了清晰起见
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}
答案 1 :(得分：0)
- 使用
DeserializeJSON()转换为结构result。 - 使用
result.data循环浏览 - 使用
<cfquery>构造SQL INSERT语句，按<cfqueryparam>传递值
