将网络图片/文件/pdf等上传到oss

 public static String uploadPdf(String filePath, String objectName) {
//        filePath="C:\\Users\\V\\Desktop\\1733968029694.jpg";
        // 创建OSSClient实例
        OSS ossClient = new OSSClientBuilder().build(ENDPOINT, ACCESS_KEY_ID, ACCESS_KEY_SECRET);

        try {
            URL url = new URL(filePath);
            InputStream inputStream = url.openStream();
            ObjectMetadata metadata = new ObjectMetadata();
            metadata.setContentType("application/pdf");
            // 创建PutObjectRequest对象
            PutObjectRequest putObjectRequest = new PutObjectRequest(BUCKET_NAME, "storecontract/" + objectName + ".pdf", inputStream, metadata);
            // 上传文件
            ossClient.putObject(putObjectRequest);
            // 生成可访问的URL (有效期10年)
            String acturl = "https://xxxx/storecontract/" + objectName + ".pdf";
            logger.info("--地址：" + acturl);
            return acturl;
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            // 关闭OSSClient
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
        return null;
    }
