將換行符 JSON 拆分為一個數組

Question

我有一個來自 web 服務器的 JSON，如下所示：

{"timestamp":1642069251.6908009,"station_id":"ORBB","channel":5,"freq":131.725,"level":-28.1,"error":0,"mode":"2","label":"Q0","block_id":"8","ack":false,"tail":"A6-ANR","flight":"G90369","msgno":"S10A"}
{"timestamp":1642069257.00876,"station_id":"ORBB","channel":5,"freq":131.725,"level":-41.3,"error":0,"mode":"2","label":"Q0","block_id":"7","ack":false,"tail":"PH-HXO","flight":"HV6905","msgno":"S28A"}
{"timestamp":1642069259.057013,"station_id":"ORBB","channel":5,"freq":131.725,"level":-24.9,"error":0,"mode":"D","label":"Q0","block_id":"9","ack":false,"tail":"A6-ANR","flight":"G90369","msgno":"S11A"}

我已經遵循了這個答案，但我沒有在控制台中顯示任何內容。

l 無法編輯上面的數據 JSON 以提供有效的 JSON，因為它來自使用 Ajax 的數據服務器。

   $(document).ready(() => {
         $.ajax('acarsdec.json', {
        type: 'GET',
        //dataType: "text",
        timeout: 10000,
        cache: false,
        
}).done(function (data, textStatus, jqXHR) {
const dataasfile = `data:text/plain;base64,${btoa(data)}`;

fetch(dataasfile).then(res => res.text()).then(text => {
  let jsonstr = `[${text.split('\n').join(',')}]`;
  let json = JSON.parse(jsonstr);
  console.log(json);
});
    })

    })

Answer 1

作為起點，您顯示的代碼段無效 JSON，因此沒有理由嘗試將其解析為 JSON。

如果您可以相信來源是“偽”JSON，每行一個 object，您可以在新行 (\n) 上拆分文本，然后用逗號 (,) 再次加入字符串，然后在字符串周圍加上方括號：

let jsonstr = `[${text.split('\n').join(',')}]`;

在這里，我使用 fetch function 和數據 URL 來模擬 AJAX 請求。
