分段复制
分段复制是分段上传的一种特殊情况,即分段上传任务中的段通过复制OBS指定桶中现有对象(或对象的一部分)来实现。您可以通过ObsClient.CopyPart来复制段。示例代码如下:
// 初始化配置参数 ObsConfig config = new ObsConfig(); config.Endpoint = "https://your-endpoint"; // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全;本示例以ak和sk保存在环境变量中为例,运行本示例前请先在本地环境中设置环境变量AccessKeyID和SecretAccessKey。 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/intl/zh-cn/usermanual-ca/ca_01_0003.html string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine); string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine); // 创建ObsClient实例 ObsClient client = new ObsClient(accessKey, secretKey, config); // 复制段 try { CopyPartRequest request = new CopyPartRequest(); request.BucketName = "bucketname"; request.ObjectKey = "objectname"; request.UploadId = "uploadId"; request.PartNumber = 1; request.SourceBucketName = "sourcebucketname"; request.SourceObjectKey = "sourceobjectname"; CopyPartResponse response = client.CopyPart(request); Console.WriteLine("Copy part response: {0}", response.StatusCode); } catch (ObsException ex) { Console.WriteLine("ErrorCode: {0}", ex.ErrorCode); Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage); }
