1、通过服务器上传

java 复制代码

// 创建OSSClient实例。
        ClientBuilderConfiguration clientBuilderConfiguration = new ClientBuilderConfiguration();
        // 设置签名版本为V4
        clientBuilderConfiguration.setSignatureVersion(SignVersion.V4);
        // 端点（例如 https://oss-cn-shenzhen.aliyuncs.com）    ACCESS_KEY      ACCESS_KEY_SECRET
        OSS ossClient = new OSSClientBuilder().build(AliConstant.ENDPOINT, AliConstant.ACCESS_KEY_ID, AliConstant.ACCESS_KEY_SECRET);


        try {

            // 创建PutObjectRequest对象。                            存储桶名称   文件名称全路径    文件字节数组
            PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, objectName, new ByteArrayInputStream(file.getBytes()));

            // 上传
            ossClient.putObject(putObjectRequest);
                
            //https://存储桶名称.oss-cn-shenzhen.aliyuncs.com/2025-03/e67a1e38-c83b-48f1-a17b-1db4225eae0c.jpg
            return AjaxResult.success("https://存储桶名称.oss-cn-shenzhen.aliyuncs.com/".concat(objectName));
        } catch (Exception oe) {
            throw new ServiceException("上传失败！");
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }

2、通过前端直传

后端生成临时上传url，设置过期时间，即可实现前端直接上传，不用通过服务器中转

java 复制代码

     /**
     * 获取临时上传url
     */
    @Override
    public AjaxResult getTempPutUrl(String encodedTeam, String encodedMatchName) {
        if (!StringUtils.hasText(encodedTeam)){
            return AjaxResult.error("队伍为空");
        }
        if (!StringUtils.hasText(encodedMatchName)){
            return AjaxResult.error("比赛为空");
        }
        String team = URLDecoder.decode(encodedTeam, StandardCharsets.UTF_8);
        String matchName = URLDecoder.decode(encodedMatchName, StandardCharsets.UTF_8);
        String endpoint = AliConstant.ENDPOINT; // 替换为实际Endpoint
        String bucketName = AliConstant.BUCKET_NAME;
        String objectName = matchName.concat("/").concat(team).concat("/").concat(IdUtil.fastSimpleUUID()).concat(".png");

        CredentialsProvider credentialsProvider = new DefaultCredentialProvider(
                AliConstant.ACCESS_KEY_ID, AliConstant.ACCESS_KEY_SECRET);


        OSS ossClient = OSSClientBuilder.create()
                .endpoint(endpoint)
                .credentialsProvider(credentialsProvider)
                .build();

        try {
            // 设置URL过期时间：
            Date expiration = new Date(System.currentTimeMillis() + 10 * 1000L);
            GeneratePresignedUrlRequest request = new GeneratePresignedUrlRequest(
                    bucketName, objectName, HttpMethod.PUT);
            request.setExpiration(expiration);
            request.setProcess(null);
            request.setContentType("image/png"); // 可选：指定上传时的 Content-Type
            return AjaxResult.success(ossClient.generatePresignedUrl(request));
        } catch (Exception e) {
            e.printStackTrace();
            throw new GlobalException("获取上传STS失败");
        } finally {
            ossClient.shutdown();
        }

    }
