是否有一种普遍接受的技术可以有效地将JavaScript字符串转换为ArrayBuffers,反之亦然？具体来说,我希望能够将ArrayBuffer的内容写入localStorage并将其读回.

我有以下下载文件的请求（使用vue-resource）：

this.$http.get(fileUrl, { responseType: 'arraybuffer' }).
    then(
        (response) => {
            let blob = new Blob([response.data], { type: response.headers.get('content-type') });
            let link = document.createElement('a');
            link.setAttribute("type", "hidden");
            link.href = window.URL.createObjectURL(blob);
            let disposition = response.headers.get('content-disposition');
            let matches = /.*filename=(.*);.*/.exec(disposition);
            let filename = (matches != null && matches[1])
                ? matches[1]
                : 'file';
            if (filename.startsWith('"')
                && filename.endsWith('"')) {
                filename = filename.substr(1, filename.length - 2);
            }
            link.download = filename;
            document.body.appendChild(link);
            link.click();
            link.remove();
        },
        (errorResponse) => {
            // TODO: errorResponse doesn't actually have the error …
