复制多版本对象

您可以通过OBSCopyObjectRequest接口传入版本号(versionID)来复制多版本对象,示例代码如下:

static OBSClient *client;NSString *endPoint = @"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/usermanual-ca/ca_01_0003.htmlchar* ak_env = getenv("AccessKeyID");char* sk_env = getenv("SecretAccessKey");NSString *AK = [NSString stringWithUTF8String:ak_env];NSString *SK = [NSString stringWithUTF8String:sk_env];    // 初始化身份验证OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];    //初始化服务配置OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];    // 初始化clientclient = [[OBSClient alloc] initWithConfiguration:conf];    OBSCopyObjectRequest *request = [[OBSCopyObjectRequest alloc]initWithSrcBucketName:@"source-bucketname" srcObjectKey:@"objectname1" dstBucketName:@"destination-bucketname" dstObjectKey:@"objectname2"];    // 被拷贝对象多版本IDrequest.srcObjectVersionID = @"testVersionID";[client copyObject:request completionHandler:^(OBSCopyObjectResponse *response, NSError *error){    NSLog(@"%@",response);}] ;
