如何使用dropbox-saver API在Dropbox上保存文件

Question

我与您分享了我的代码的一部分，用于对文件进行加密。当我尝试在本地硬盘驱动器上保存加密文件时，此代码工作正常，但当我尝试使用JavaScript Saver API在云上保存加密文件时，我只是以数据URI的形式获取数据。你们中谁都知道如何解决这个问题？

// JavaScript代码：

// The HTML5 FileReader object will allow us to read the 
    // contents of the  selected file.

    var reader = new FileReader();

    if(body.hasClass('encrypt')){

        // Encrypt the file!

        reader.onload = function(e){

            // Use the CryptoJS library and the AES cypher to encrypt the 
            // contents of the file, held in e.target.result, with the password

            var encrypted = CryptoJS.AES.encrypt(e.target.result, password);

            // The download attribute will cause the contents of the href
            // attribute to be downloaded when clicked. The download attribute
            // also holds the name of the file that is offered for download.


            a.attr('href', 'data:application/octet-stream,' + encrypted);
            a.attr('download', file.name + '.encrypted');



            step(4);
        };

        // This will encode the contents of the file into a data-uri.
        // It will trigger the onload handler above, with the result

        reader.readAsDataURL(file);
    }

// HTML代码     

            <div class="content">
                <h1>Your file is ready!</h1>
                <a class="button download green">Download on Computer</a>
                <a class="button download dropbox-saver green">Cloud</a>

            </div>

        </div>
