javascript - 无法读取 Node.JS 中的嵌套 JSON 对象

Question

我有一个名为“data”的 JSON Node ，它有一个 id。我想存储该 id 的值，但无法使用当前语法执行此操作，并且收到一条错误消息，指出它未定义。

我应该如何更改我的代码才能使其正常工作？

我的代码片段:

const transfer_ID = data.items.id;
    console.log("This is the transfer tree obtained", data);

数据:

{ entity: 'collection',
  count: 1,
  items: 
   [ { id: 'trf_Ary1cWasdfGmHAc',
       entity: 'transfer',
       source: 'pay_ASrxasdfetwhAFv',
       amount: 390000,
       currency: 'INR',
       amount_reversed: 0,
       notes: [],
       fees: 1151,
       tax: 176,
       on_hold: false,
       on_hold_until: null,
       recipient_settlement_id: null,
       created_at: 1530208843 } ] }

检查以下代码片段

var data ={ entity: 'collection',
  count: 1,
  items: 
   [ { id: 'trf_Ary1cWasdfGmHAc',
       entity: 'transfer',
       source: 'pay_ASrxasdfetwhAFv',
       amount: 390000,
       currency: 'INR',
       amount_reversed: 0,
       notes: [],
       fees: 1151,
       tax: 176,
       on_hold: false,
       on_hold_until: null,
       recipient_settlement_id: null,
       created_at: 1530208843 } ] } 
       
   var id =  data.items[0].id;
   console.log(id);
