對象沒有被正確地推送到數組

Question

我有一個偵聽新消息的事件偵聽器，我想將所有新消息推送到一個數組，但是當我檢查結果時，我看到只有字符串被推送。

這是我的代碼：

async function consume() {
  try {
    let result = [];
    const connection = await amqps.connect(URL);
    const channel = await connection.createChannel();
    await channel.consume("messages", function (message) {
      result.push(JSON.parse(message.content.toString()));
    });
    return result;
  } catch (error) {
    console.log(error);
  }
}

當我調用 consume 方法並檢查結果時，這是返回的內容：

[
  'yoyo',   'yoyo',
  'yoyo',   'yoyo',
  'yoyo',   'yoyo',
  '',       'hi you',
  'hi you', 'hi you',
  'hi you', 'hi you',
  'hi you', 'hi you'
]

但是，當我從偵聽器 function 中記錄JSON.parse(message.content.toString())時，我可以看到對象：

...
hi you
hi you
hi you
{
  read: false,
  timeSent: 1645945954348,
  message: 'Hchxh',
  userID: 41,
  contactID: 46
}
{
  read: false,
  timeSent: 1645945990969,
  message: 'Gry',
  userID: 41,
  contactID: 46
}
...

這是從偵聽器中記錄message.content.toString() （不解析）時的結果：

"hi you"
"hi you"
"hi you"
{"read":false,"timeSent":1645945954348,"message":"Hchxh","userID":41,"contactID":46}
{"read":false,"timeSent":1645945990969,"message":"Gry","userID":41,"contactID":46}
{"read":false,"timeSent":1645946032914,"message":"Ti","userID":41,"contactID":46}
{"read":false,"timeSent":1645946119720,"message":"Ge","userID":41,"contactID":46}
{"read":false,"timeSent":1645946454158,"message":"Beuh","userID":41,"contactID":46}
{"read":false,"timeSent":1645948170050,"message":"Xhxh","userID":41,"contactID":46}

關於我做錯了什么的任何想法？

試試這個語法：

async function consume() {
  try {
    const connection = await amqps.connect(URL);
    const channel = await connection.createChannel();
    const result = await channel.consume('messages');
    return result.content.toString();
  } catch (error) {
    console.log(error);
  }
}

如果你願意，你可以解析它，即使我不確定你為什么需要解析它。
