我收到一个错误：“无法构造'Blob'：迭代器getter不可调用。”我想知道如何使用CryptoJS哈希每个文件。感谢您的帮助。

     document.querySelector("#actions .start").onclick = function () {
        //myDropzone.enqueueFiles(myDropzone.getFilesWithStatus(Dropzone.ADDED));
        console.log(myDropzone.getFilesWithStatus(Dropzone.ADDED).length);
        for (i = 0; i < myDropzone.getFilesWithStatus(Dropzone.ADDED).length; i++) {


            let reader = new FileReader();
            var blob = new Blob(myDropzone.getFilesWithStatus(Dropzone.ADDED)[i]);
            reader.readAsArrayBuffer(blob);
            reader.onload = function () {
                var wordarray = CryptoJS.lib.Wordarray.create(reader.result);
                var hash = CryptoJS.SHA3(wordarray,{outputLength: 224}).toString();
                console.log(hash);
            };
        }
    };
