OSS文件打包下载

OSS文件打包下载：

直接上代码如下：

/**
     * 测试-批量打包下载
     * @param ossFileKeyPaths  对应文件的 key 和 name
     * @param zipFileName 整个包的名称
     * @param response
     */
    @Override
    public void batchDownLoadOssFile(Map<String,String> ossFileKeyPaths, String zipFileName, HttpServletResponse response) {
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/zip; charset=utf-8");
        //要下载成什么类型的文件，这里直接加后缀
        response.setHeader("Content-Disposition", "attachment;fileName=" + zipFileName + ".zip");

                /*Date expiration = new Date(new Date().getTime() + 3600 * 1000);
                URL signedUrl = ossClient.generatePresignedUrl(bucketName, ossFileKeyPath, expiration);*/
                // 使用签名URL发送请求。
