如何迭代JSON有效负载并在wso2中构造响应

Question

如何通过将carValue和bikeValue添加到id中来迭代结果数组并构造Response数组（＆＃34; C_05＆＃34; - ＆＃34; B_08＆＃34; /＆＃34; C_07＆＃34; /＆＃响应数组的34; B_06＆＃34;）并保持与描述相同的描述。

JSON有效负载请求：

{"results": [
      {
      "desc": "Blind",
      "carValue": "05",
      "bikeValue": "08"
   },
      {
      "desc": "Deaf",
      "carValue": "09",
      "bikeValue": "10"
   },
{
      "desc": "Oxygen",
      "carValue": "07"
   },
{
      "desc": "carbon",
      "bikeValue": "06"
   }]
}

最终答案应为：

{
  "Response" : [
   {
    "id" : "C_05"-"B_08",
    "description" : "Blind"
   },
   {
    "id" : "C_09"-"B_10",
    "description" : "Deaf"
   },
   {
    "id": "C_07",
    "description": "Oxygen"
   },
   {
    "id": "B_06",
    "description": "carbon"
   }]
}

Answer 1

您可以使用迭代，聚合和脚本调解器，正如我在此代理中所示。

<ul class="form-group mb-0">
    <label>Choose your holiday: </label>
    <li>
        <input type="radio" id="Tour" name="holiday" class="check" data-form="form1" checked>
        <label for="Tour">Tour</label>
    </li>
    <li>
        <input type="radio" id="Cruise" name="holiday" class="check" data-form="form2" />
        <label for="Cruise">Cruise</label>
   </li>
   <li>
        <input type="radio" id="Beach" name="holiday" class="check" data-form="form3" />
        <label for="Beach">Beach</label>
   </li>
</ul>

<form name="form1" id="form1" class="form active">
1
</form>
<form name="form2" id="form2"  class="form">
2
</form>
<form name="form3" id="form3"  class="form">
3
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(".check").click(function () {
    $(".form").removeClass("active");
     if ($(this).is(":checked")) {
        var form = $(this).data('form');
        //alert(form);
        $('#'+form).addClass("active");
     }
});
</script>

您还可以使用custom或payloadFactory介体生成Json响应
