Question

这是我的代码。我可以下载zip文件，但现在我想使用javascript / jquery为它设置密码。

    function saveAsZip(fileContents, fileName) {

    var zip = new JSZip();
    zip.file(fileName, fileContents);
    var content = zip.generate();
    var link = document.createElement('a');
    var linkName = fileName.replace('.XML', '')
    link.download = linkName + '.zip';
    link.href = "data:application/zip;base64," + content;
    link.click();   

}

实际上，到目前为止，这是不可能的，如下所述：

如果你在linux上使用node.js，这个问题可能是实现它的一种方法：How do I password protect a zip file in Nodejs?

我最终在Dot Net中使用Ionic.Zip。这是我的html和javascript代码

<div>
    <input type="password" id="pass" placeholder="Set Password" />
    <button type="submit" class="cutomDownloadCCDA">Zip</button>
</div>
<script>
$('.cutomDownloadCCDA').click(function(e) {
    //window.location.href = "Home/Zip";// Simple Way

    var password = $('#pass').val();
    $('#downloadFrame').remove(); // This shouldn't fail if frame doesn't exist
    $('body').append('<iframe id="downloadFrame" style="display:none"></iframe>');
    $('#downloadFrame').attr('src', '/Home/Zip?password=' + password);
});
</script>

这是MVC的动作方法

public void Zip(string password)
    {
        using (ZipFile zip = new ZipFile())
        {
            string xml = "Your XML Data";

            var newStream = new MemoryStream();
            var newWriter = XmlWriter.Create(newStream);
            newWriter.WriteRaw(xml);
            newStream.Position = 0;
            newWriter.Flush();
            newStream.Seek(0, SeekOrigin.Begin);

            // Ist File
            ZipEntry e = zip.AddEntry("test.xml", newStream);
            e.Password = password;
            e.Encryption = EncryptionAlgorithm.WinZipAes256;

            // 2nd File    
            //ZipEntry f2 = zip.AddEntry("test1.xml", newStream);
            //f2.Password = "456";
            //f2.Encryption = EncryptionAlgorithm.WinZipAes256;

            Response.ContentType = "application/zip";
            Response.AddHeader("Content-Disposition", "attachment;filename=somefile.zip");
            zip.Save(Response.OutputStream);
        }
    }
