shared_ptrstring objectName{}; shared_ptrPutObjectRequestHeader header{}; shared_ptrDarabonba::Stream body{}; // 验证逻辑 void validate() override { if (!bucketName) { BOOST_THROW_EXCEPTION( std::runtime_error(bucketName is required.)); } if (!objectName) { BOOST_THROW_EXCEPTION( std::runtime_error(objectName is required.)); } } };高级功能实战演练分块上传与断点续传OSS SDK提供了完整的分块上传支持适用于大文件上传场景// Java分块上传示例 InitiateMultipartUploadRequest initRequest new InitiateMultipartUploadRequest();
