设置事件通知

您可以通过setBucketNotification设置桶的事件通知。以下代码展示了如何设置桶的事件通知：

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];
    
// 设置事件通知
OBSSetBucketNotificationRequest *request = [[OBSSetBucketNotificationRequest alloc]initWithBucketName:@"bucketname" ];
    
OBSNotificationFilter *filter = [OBSNotificationFilter new];
    
OBSNotificationFilterRule *rule1 = [[OBSNotificationFilterRule alloc] initWithName:@"prefix" value:@"smn/"];
OBSNotificationFilterRule *rule2 = [[OBSNotificationFilterRule alloc] initWithName:@"suffix" value:@".jpg"];
[filter.filterRuleList addObject:rule1];
[filter.filterRuleList addObject:rule2];
    
OBSNotificationTopicConfiguration *topicConf = [OBSNotificationTopicConfiguration new];
topicConf.topic = [NSString stringWithFormat:@"urn:smn:%@:%@:topic001",@"region",@"ownerID"] ;
topicConf.ID = @"Id001";
topicConf.filter = filter;
[topicConf.eventList addObject:@"Your Event Type"];

[request.configurationList addObject:topicConf];
    
[client setBucketNotification:request completionHandler:^(OBSSetBucketNotificationResponse *response, NSError *error){
    NSLog(@"%@",response);
}];
