Obtaining Bucket Metadata
You can call getBucketMetaData to obtain bucket metadata.
Sample code:
static OBSClient *client; NSString *endPoint = @"your-endpoint"; // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey. // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/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]; // Initialize identity authentication. OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK]; //Initialize service configuration. OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider]; // Initialize an instance of OBSClient. client = [[OBSClient alloc] initWithConfiguration:conf]; //Obtain the bucket metadata. OBSGetBucketMetaDataRequest *request = [[OBSGetBucketMetaDataRequest alloc]initWithBucketName:@"bucketname"]; [client getBucketMetaData:request completionHandler:^(OBSGetBucketMetaDataResponse *response, NSError *error){ NSLog(@"%@",response); }];
