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copyPart来复制段。以下代码展示了如何使用分段复制对象:

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/intl/zh-cn/usermanual-ca/ca_01_0003.html
char* 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client
client = [[OBSClient alloc] initWithConfiguration:conf];
 
// 拷贝段
OBSCopyPartRequest* copyRequest =
[[OBSCopyPartRequest alloc]initWithSrcBucketName:@"buckeName"
                                        srcObjectKey:@"MultiPart"
                                    uploadBucketName:@"bucketName"
                                     uploadObjectKey:@"MultiPart"
                                    uploadPartNumber:[NSNumber numberWithInt:3]
                                            uploadID:@"uploadID"];
    
[client copyPart:copyRequest completionHandler:^(OBSCopyPartResponse *response, NSError *error) {
    NSLog(@"%@",response);
}];
