The Internet Explorer browser does not download the file correctly

  • 772

I have a problem downloading a file with Internet Explorerany version. My problem is that I receive an array of bits from my controller which I receive in a JSONand download from javascript.

Note: I do not have a physical file on the server, this file is obtained from a storagethrough a WebService.

The code works fine in other browsers but not inInternet Explorer

$.ajax({
    type: 'POST',
    url: '/Portal/GetXML',
    data: $('#formDownload2' + id).serialize(),
    success: function (data) {
        if (data.error == "") {
            //aquí empieza la descarga del archivo
            var arr = data.Archivo;
            var byteArray = new Uint8Array(arr);
            var a = window.document.createElement('a');
            a.href = window.URL.createObjectURL(new Blob([byteArray], { type: 'application/octet-stream' }));
            a.download = data.Nombre;
            // Append anchor to body.
            document.body.appendChild(a)
            a.click();
            // Remove anchor from body
            document.body.removeChild(a)
        } else {
            $.jGrowl("" + data.error, {
                header: "Error",
                //sticky: true,
                theme: "red"
            });
        }
    }
});

All it does is download a file with a long name and no extension. On other computers with Internet Explorerdownload a file with extension:.JSON

Why is it that I download them that way? and how can I solve it?

javascript

    This is classic of Internet Explorer, it is because said browser does not know what to do with contentapplication/json

    What we must specify is the content when we return JSONwe define: string Content Type: "text/html"

    In your controller that returns JSON:

    return Json(loQueRetorna, "text/html");

    I suggest text/htmlyou define it as long as the browser is IE.
