我有一个像这样开头的json。我可以毫无问题地访问 User、Claim 和相关的一级数据。我正在尝试访问 ClaimResponse 中特定变量的数据（即 User.id=3 的位置）。我已经尝试过

x.ClaimResponse[用户名].id
，没有运气。关于如何获取这些数据的任何直接想法？

您是否尝试获取具有特定 ID 的特定 ClaimResponse？如果是这样，试试这个：

var arr = x.ClaimResponse,
    userId = "3", //Set this to the uid you want
    length = arr.length,
    claim = null; //This variable stores the correct claim

for (var i = 0; i < length; i++) {
  claim = arr[i];
  if (claim.id === userId) {
    break;
  }
}

[] 运算符用于根据数组中的索引获取数据，例如，如果 ClaimResponse[0] 你得到 id 为 4 的用户

您可以在使用返回数组的键 ClaimResponse 获取数据后对得到的数组运行 for 循环。

public static JSONObject ObjectWithIdandReponse(int _id,JSONArray responseArray) {
    for (JSONObject Obj in responseArray)
    {
     if(Obj.id==_id)
     return Obj;
    }
}

制作返回 JSON Obj 并将参数作为用户 ID 和声明数组传递的方法
