Setting Versioning Status for a Bucket

You can call setBucketVersioning to set the versioning status for a bucket. OBS supports two versioning statuses.

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];
    
// Enable versioning for a bucket.
OBSBucketVersioningConfiguration *conf1 = [OBSBucketVersioningConfiguration new];
    
conf1.status = OBSVersioningStatusEnabled;
// Configure versioning.
OBSSetBucketVersioningRequest *request = [[OBSSetBucketVersioningRequest alloc] initWithBucketName:@"bucketname" configuration: conf];
[client setBucketVersioning:request completionHandler:^(OBSSetBucketVersioningResponse *response, NSError *error) {
    NSLog(@"%@",response);
}];
