查询已上传华为云视频的时长，大小等基础信息

1.首先添加相应的依赖

        
            com.aliyun
            dysmsapi20170525
            2.0.4
        
        
            com.aliyun
            aliyun-java-sdk-core
            4.5.16
        

2.Service定义的需要在配置文件里面去配置

// 日志打印
import com.btn.common.exception.ErrorCodeEnum;
import com.cloud.sdk.ServiceException;
import com.huawei.mpc.client.MpcClient;
import com.huawei.mpc.client.MpcConfig;
import com.huawei.mpc.model.ObsObjInfo;
import com.huawei.mpc.model.extract.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

            mpcConfig.setEndPoint(mpcendPoint);
            mpcConfig.setProjectId(projectId);

            CreateExtractTaskReq req = new CreateExtractTaskReq();
            req.setInput(input);
            // MPC客户端创建视频解析请求并返回
            CreateExtractTaskRsp extractTask = mpcClient.createExtractTask(req);
            MetaData metadata = extractTask.getMetadata();
            return metadata;
        }catch (ServiceException exception){
            throw new com.btn.common.exception.ServiceException(ErrorCodeEnum.FAIL.getErrorCode(),"视频解析任务异常-->"+ exception.getErrorMessage());
        }
    }
