# 后端ossutil工具类 #

*  http协议注意点

content-Type 为 application/pdf
    Content-Disposition 为 空 (否则浏览器默认认为是下载)

*  不要设置meta.setContentDisposition(disposition);

public static URL uploadFile(InputStream inputStream,String fileName,boolean setDis) throws IOException {
            OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
            // 上传文件流。
            ObjectMetadata meta = new ObjectMetadata();
            fileName = DateUtils.getDangQianShiJianHaoMiao() + fileName;
            // 添加时间戳。
            if(setDis){
                String disposition = "attachment;filename=\"" + fileName + "\"";
                meta.setContentDisposition(disposition);
            }
    //        ossClient.putObject("<yourBucketName>", "<yourKey>", new ByteArrayInputStream(content.getBytes()), meta);
            PutObjectResult putObjectResult = ossClient.putObject(bucketName, fileName, inputStream,meta);
            Date expiration = new Date(new Date().getTime() + 3600l * 1000 * 24 * 365 * 10000);
            URL url = ossClient.generatePresignedUrl(bucketName ,fileName, expiration);
            // 关闭OSSClient。
            ossClient.shutdown();
            log.debug(putObjectResult.toString());
            return url;
        }
