官方SDK快速入门

依赖导入

<dependency>
     <groupId>com.qcloud</groupId>
     <artifactId>cos_api</artifactId>
     <version>5.6.155</version>
</dependency>

注入COSClient实例

CosConfig.java

/**
 * @author 追梦路上的孩子
 * @version 1.0
 * @date 2024/1/19 9:27
 */
@Configuration
@EnableConfigurationProperties(CosConfigProperties.class)
public class CosConfig {
    @Autowired
    private CosConfigProperties cosConfigProperties;

    @Bean
    public COSClient cosClient() {
        BasicCOSCredentials cred = new BasicCOSCredentials(cosConfigProperties.getSecretId(), cosConfigProperties.getSecretKey());
        Region region = new Region(cosConfigProperties.getRegion());
        ClientConfig clientConfig = new ClientConfig(region);
        return new COSClient(cred, clientConfig);
    }
}

CosConfigProperties.java

/**
 * @author 追梦路上的孩子
 * @version 1.0
 * @date 2024/1/19 9:27
 */
@Data
@ConfigurationProperties("tencent.cos")
public class CosConfigProperties {
    private String secretId;
    private String secretKey;
    private String region;
    private String bucketName;
    private String baseUrl;
}

配置密钥和属性

application.yml

# 腾讯云cos配置
tencent:
  cos:
    secret-id: AKIDymcr03vqhNwPNDznP6iDWdnwxxxxxxxxx  （填写自己的密钥id）
    secret-key: pZDxeSG4wndN2cz83GNY5lQTgrxxxxxx      （填写自己的密钥key）
    region: ap-guangzhou                              （填写自己的地域名)
    bucket-name: oa-bucket-1305854520                 （填写自己的存储桶名称）
    base-url: https://cos.hyqstudio.top/              （填写自己的访问域名)

编写接口

CosService.java

/**
 * @author 追梦路上的孩子
 * @version 1.0
 * @date 2024/1/19 9:47
 */
public interface CosService {
    /**
     *  图片上传
     * @param multipartFile 源文件
     * @return url地址
     */
    String uploadImage(MultipartFile multipartFile);
}

实现类

CosServiceImpl.java

/**
 * @author 追梦路上的孩子
 * @version 1.0
 * @date 2024/1/19 9:48
 */
@Service
public class CosServiceImpl implements CosService {
    private static final String BASE_PATH = "images/";
    @Autowired
    private CosConfigProperties cosConfigProperties;
    @Autowired
    private COSClient cosClient;

    @Override
    public String uploadImage(MultipartFile multipartFile) {
        String originalFilename = multipartFile.getOriginalFilename();
        assert originalFilename != null;
        String key = getFilePath() + getFileName(originalFilename);
        try {
            //调用hutool工具类去判断是否为图片
            String type = FileTypeUtil.getType(multipartFile.getInputStream(), true);
            if (ObjectUtils.isEmpty(type) || !IMAGE_SUFFIX_LIST.contains(type)) {
                throw new ServiceException(ResultStatus.IMAGE_TYPE_ERROR);
            }
            PutObjectRequest putObjectRequest = new PutObjectRequest(cosConfigProperties.getBucketName(),
                    key, multipartFile.getInputStream(), new ObjectMetadata());
            cosClient.putObject(putObjectRequest);
        } catch (ServiceException ex) {
            throw new ServiceException(ResultStatus.IMAGE_TYPE_ERROR);
        } catch (CosServiceException | IOException e) {
            throw new ServiceException(ResultStatus.FILE_UPLOAD_FAILED);
        }

        return cosConfigProperties.getBaseUrl() + key;
    }

    /**
     * @param oldFileName 源文件名
     * @return 新的文件名
     */
    private String getFileName(String oldFileName) {
        return String.format("%s%s%s",
                DateUtil.format(LocalDateTime.now(), "yyyyMMddHHmmss"),
                RandomUtil.randomString(4),
                oldFileName.substring(oldFileName.lastIndexOf(".")));
    }

    /**
     * @return 文件存储路径
     */
    private String getFilePath() {
        return String.format("%s%s", BASE_PATH, DateUtil.format(LocalDateTime.now(), "yyyy-MM-dd") + "/");
    }
}
