设置桶标签

您可以通过setBucketTagging设置桶标签。以下代码展示了如何设置桶标签：

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];
    
// 设置桶标签
OBSSetBucketTaggingRequest *request = [[OBSSetBucketTaggingRequest alloc]initWithBucketName:@"bucketname"];
[request.tagList addObject:[[OBSBucketTag alloc]initWithKey:@"tagkey" value:@"tagvalue"]];
[request.tagList addObject:[[OBSBucketTag alloc]initWithKey:@"tagkey1" value:@"tagvalue1"]];
    
[client setBucketTagging:request completionHandler:^(OBSSetBucketTaggingResponse *response, NSError *error){
    NSLog(@"%@",response);
 }];
