Question

我尝试使用以下代码在设备“ mac os”上下载json对象。结果是在浏览器上显示json正文，尽管它可以与其他操作系统“ android，windows”一起使用。

是否有其他解决方案？

function downloadJsonFile(fileName, jsonObject) {
    let fileContents = JSON.stringify(jsonObject);
    let data = "text/json;charset=utf-8," + encodeURIComponent(fileContents);
    let a = document.createElement('a');
    a.href = 'data:' + data;
    a.download = fileName + '.json';
    a.click();
}

尝试这样的事情：

演示----> Download Json

  download(strData, strFileName, strMimeType) {

    strData = JSON.stringify(strData);
    var D = document,
      A = arguments,
      a = D.createElement("a"),
      n = A[1];
    a.href = "data:" + strMimeType + "charset=utf-8," + (strData);
    if ('download' in a) {
      a.setAttribute("download", n);
      a.innerHTML = "downloading...";
      D.body.appendChild(a);
      setTimeout(function () {
        var e = D.createEvent("MouseEvents");
        e.initMouseEvent("click", true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
        a.dispatchEvent(e);
        D.body.removeChild(a);
      }, 66);
      return true;
    }; 
    var f = D.createElement("iframe");
    D.body.appendChild(f);
    f.src = "data:" + (A[2] ? A[2] : "application/octet-stream") + (window.btoa ? ";base64" : "") + "," + (strData);
    setTimeout(function () {
      D.body.removeChild(f);
    }, 333);
    return true;
  }

在Mac OS上使用Angular 5下载/导出json文件
