Obtaining Object Properties
You can call getObjectMetaData to obtain properties of an object, including the length, MIME type, and customized metadata. Sample code is as follows:
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 object properties. OBSGetObjectMetaDataRequest *request = [[OBSGetObjectMetaDataRequest alloc]initWithBucketName:@"bucketname" objectKey:@"objectname"]; [client getObjectMetaData:request completionHandler:^(OBSGetObjectMetaDataResponse *response, NSError *error){ NSLog(@"meta:%@\n storageClass:%@\n websiteRedirectlocation:%@\n size:%@",response.metaDataDict,response.storageClass,response.websiteRedirectLocation,response.size); }];
