Question

您好，这些代码确实请求Steam Web API

 val query = s"select count(*) from schema.table"
    val connection = getMySqlConnection(...)
    val rs = connection.createStatement().executeQuery(query)
    rs.next()
    val count = rs.getLong(1)
    connection.close()
    count

这就是它的返回内容：

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']);
});

但是当我试图通过这种方式获取accountid_other的价值时：

{
  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
    }
  ]
}

返回未定义

Answer 1

fpath = 'file.txt' with open(fpath, 'r+') as f: lines = f.readlines() f.seek(0) f.truncate() for line in lines: line = line.replace('https://', '') f.write(line)中的方括号[ ... ]表示它包含一个数组，而不仅仅是一个项目（它恰好是数组中的一个项目）。因此，要获得您感兴趣的价值，您需要指定所需项目的索引或使用循环来遍历它。在这种情况下，您需要第一项，可以使用trade_offers_sent来获取它。

为什么Steam Web API返回未定义的JSON值节点JS
