删除多版本对象

删除单个多版本对象

您可以通过OBSDeleteObjectRequest接口传入版本号(versionID)删除多版本对象,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/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];
    
// 删除对象
OBSDeleteObjectRequest *request = [[OBSDeleteObjectRequest alloc] initWithBucketName:@"bucketname" objectKey:@"objectname"];
    
// 设置多版本ID
request.versionID = @"versionID";
    
[client deleteObject:request completionHandler:^(OBSDeleteObjectResponse *response, NSError *error) {
    NSLog(@"%@",response);
}];

批量删除多版本对象

您可以通过OBSDeleteObjectsRequest接口传入每个待删除对象的版本号(versionID)批量删除多版本对象,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/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];
    
// 批量删除对象
OBSDeleteObjectsRequest *deleteRequest = [[OBSDeleteObjectsRequest alloc] initWithBucketName:@"bucketname"];
    
// 多版本删除对象
OBSObjectToDelete *object = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname" versionID:@"versionID"];
OBSObjectToDelete *object1 = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname" versionID:@"versionID"];
    
deleteRequest.objectList = @[object,object1];
    
[client deleteObjects:deleteRequest completionHandler:^(OBSDeleteObjectsResponse *response, NSError *error) {
    NSLog(@"%@",response);
}];
