WSO2 Lopp 通過 Json 陣列

Question

這是我的輸入 Json：

如何獲取“值”字段並將其設置為屬性？

 [
        {
            "Name": "Утасны дугаар",
            "Value": "95252351",
            "ParameterName": "{xacparam01}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        },
        {
            "Name": "dans",
            "Value": "99115544",
            "ParameterName": "{xacparam02}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        },
        {
            "Name": "dfd",
            "Value": "88554455",
            "ParameterName": "{xacparam03}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        }
    ]

當我循環通過 json 時，我只能獲得最后一次迭代

所需的 Output：

{
"val1" : "95252351",
"val2" : "99115544",
"val3" : "88554455"
}

Answer 1

無法為 JSON object 生成字段名稱。 您可以使用給定的代理獲得如下所示的 output。

output JSON

{
    "values": [
        95252351,
        99115544,
        88554455
    ]
}
