如何在两个json对象之间传递数组值

Question

我从邮递员发送JSON对象，然后我的应用程序将此JSON转换为所需的格式（再次为JSON）并发送到服务器。

我传递了邮递员提供的accountid和角色数组。在第二个JSON中，我想动态读取并传递第二个JSON中的值

邮递员的JSON（第一个JSON）

{
    "firstName":"holl",
    "lastName":"land",
    "emailAddress":"biz@foo.com",
    "userName":"savapa",
     "roles" : 
[
 ***//I pass an array of accountid and roles***

  {
    "accountid" : "Acc444",
     "role" :  "Admin"
  },
  {

   "accountid" : "Footballer",
   "role" :  "Non Admin"
   }
 ]
} 

**Object passed to server ( second JSON)**

 createUserRequest: {
      user: {
        firstName: Request.firstName,
        lastName: Request.lastName,
        emailAddress: Request.emailAddress,
        userName:Request.userName,

        orgRolesList:{
           for( i in Request.roles ){ 
  ***// I tried this to loop over array of accountid and roles passed***
            orgRoles:[
              {
                organization:{
                primaryKeys:{
                  name:Request.roles[i].accountid
                }
              }, 
              roles:{
                role:{
                  primaryKeys:{
                    name:Request.roles[i].role
                  }
                }
              }
            }
