为什么Steam Web API返回未定义的json值节点js

Question

您好，这些代码确实向Steam Web API请求了

const request = require("request");
request({
    url: "https://api.steampowered.com/IEconService/GetTradeOffers/v1/?key=MYAPIKEY&get_sent_offers=1&active_only=1&format=json",
json: true
}, (err, responser, body) => {
    console.log(body.response['trade_offers_sent']);
});

这就是返回的内容：

{
  trade_offers_sent: [
    {
      tradeofferid: '3974708687',
      accountid_other: 82613664,
      message: 'test message',
      expiration_time: 1587017229,
      trade_offer_state: 9,
      items_to_give: [Array],
      is_our_offer: true,
      time_created: 1585807629,
      time_updated: 1585807629,
      from_real_time_trade: false,
      escrow_end_date: 0,
      confirmation_method: 2
    }
  ]
}

但是当我试图通过这种方式获取accountid_other的值时：

console.log(body.response['trade_offers_sent'].accountid_other);

返回未定义

这是因为您必须首先将此json作为对象。可能这段代码可以帮助您。

let jsonData = JSON.parse(response.body);
let obj= new Object(jsonData);

obj.trade_offers_sent.forEach(itemChild => {
 let accountid_other=itemChild.accountid_other;
 console.log(accountid_other);
})
