删除对象
删除单个对象
您可以通过deleteObject删除单个对象。以下代码展示如何删除单个对象:
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]; // 删除对象 OBSDeleteObjectRequest *request = [[OBSDeleteObjectRequest alloc] initWithBucketName:@"bucketname" objectKey:@"objectname"]; [client deleteObject:request completionHandler:^(OBSDeleteObjectResponse *response, NSError *error) { NSLog(@"%@",response); }];
批量删除对象
您可以通过deleteObjects批量删除对象。
每次最多删除1000个对象,并支持两种响应模式:详细(verbose)模式和简单(quiet)模式。
以下代码展示了如何进行批量删除对象:
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]; // 批量删除对象 OBSDeleteObjectsRequest *deleteRequest = [[OBSDeleteObjectsRequest alloc] initWithBucketName:@"bucketname"]; // 被删除对象列表 OBSObjectToDelete *object1 = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname1"]; OBSObjectToDelete *object2 = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname2"]; deleteRequest.objectList = @[object1,object2]; [client deleteObjects:deleteRequest completionHandler:^(OBSDeleteObjectsResponse *response, NSError *error) { for(int i=0;i<response.deletedList.count;i++){ NSLog(@"%@\n",response.deletedList[i].key); } }];
