iOS列举存储空间

列举所有存储空间

以下代码用于列举当前账号所有地域下的存储空间。

OSSGetServiceRequest * getService = [OSSGetServiceRequest new];
// 列举当前账号所有地域下的存储空间。    
OSSTask * getServiceTask = [client getService:getService];
[getServiceTask continueWithBlock:^id(OSSTask *task) {
    if (!task.error) {
        OSSGetServiceResult * result = task.result;
        NSLog(@"buckets: %@", result.buckets);
        NSLog(@"owner: %@, %@", result.ownerId, result.ownerDispName);
        [result.buckets enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
            NSDictionary * bucketInfo = obj;
            NSLog(@"BucketName: %@", [bucketInfo objectForKey:@"Name"]);
            NSLog(@"CreationDate: %@", [bucketInfo objectForKey:@"CreationDate"]);
            NSLog(@"Location: %@", [bucketInfo objectForKey:@"Location"]);
        }];
    } else {
        NSLog(@"get service failed, error: %@", task.error);
    }
    return nil;
}];

列举指定前缀的存储空间

以下代码用于列举当前账号所有地域下以example为前缀（prefix）的存储空间。

OSSGetServiceRequest * getService = [OSSGetServiceRequest new];
getService.prefix = @"example";

OSSTask * getServiceTask = [client getService:getService];
[getServiceTask continueWithBlock:^id(OSSTask *task) {
    if (!task.error) {
        OSSGetServiceResult * result = task.result;
        NSLog(@"buckets: %@", result.buckets);
        NSLog(@"owner: %@, %@", result.ownerId, result.ownerDispName);
        [result.buckets enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
            NSDictionary * bucketInfo = obj;
            NSLog(@"BucketName: %@", [bucketInfo objectForKey:@"Name"]);
            NSLog(@"CreationDate: %@", [bucketInfo objectForKey:@"CreationDate"]);
            NSLog(@"Location: %@", [bucketInfo objectForKey:@"Location"]);
        }];
    } else {
        NSLog(@"get service failed, error: %@", task.error);
    }
    return nil;
}];

列举指定marker之后的存储空间

以下代码用于列举当前账号所有地域下名称的字母序排在examplebucket之后的存储空间。

OSSGetServiceRequest * getService = [OSSGetServiceRequest new];
getService.marker = @"examplebucket";

OSSTask * getServiceTask = [client getService:getService];
[getServiceTask continueWithBlock:^id(OSSTask *task) {
    if (!task.error) {
        OSSGetServiceResult * result = task.result;
        NSLog(@"buckets: %@", result.buckets);
        NSLog(@"owner: %@, %@", result.ownerId, result.ownerDispName);
        [result.buckets enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
            NSDictionary * bucketInfo = obj;
            NSLog(@"BucketName: %@", [bucketInfo objectForKey:@"Name"]);
            NSLog(@"CreationDate: %@", [bucketInfo objectForKey:@"CreationDate"]);
            NSLog(@"Location: %@", [bucketInfo objectForKey:@"Location"]);
        }];
    } else {
        NSLog(@"get service failed, error: %@", task.error);
    }
    return nil;
}];

列举指定个数的存储空间

以下代码用于列举当前账号所有地域下的存储空间，并指定列举的最大个数为500。

OSSGetServiceRequest * getService = [OSSGetServiceRequest new];
// 列举当前账号所有地域下的存储空间，限定此次列举存储空间的最大个数为500。默认值为100，最大值为1000。
getService.maxKeys = 500;
    
OSSTask * getServiceTask = [client getService:getService];
[getServiceTask continueWithBlock:^id(OSSTask *task) {
    if (!task.error) {
        OSSGetServiceResult * result = task.result;
        NSLog(@"buckets: %@", result.buckets);
        NSLog(@"owner: %@, %@", result.ownerId, result.ownerDispName);
        [result.buckets enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
            NSDictionary * bucketInfo = obj;
            NSLog(@"BucketName: %@", [bucketInfo objectForKey:@"Name"]);
            NSLog(@"CreationDate: %@", [bucketInfo objectForKey:@"CreationDate"]);
            NSLog(@"Location: %@", [bucketInfo objectForKey:@"Location"]);
        }];
    } else {
        NSLog(@"get service failed, error: %@", task.error);
    }
    return nil;
}];
