Configuring Event Notifications

The sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in 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.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Configure event notifications.
try
{
    FilterRule filterRule1 = new FilterRule();
    filterRule1.Name = FilterNameEnum.Prefix;
    filterRule1.Value = "smn";
    TopicConfiguration topicConfiguration1 = new TopicConfiguration();
    topicConfiguration1.Id = "Id001";
    // Set the URN of the topic. You need to create a topic, for example, urn:smn:region:xxx:topicName, on SMN.
    topicConfiguration1.Topic = "your topic1 URN";
    topicConfiguration1.Events.Add(EventTypeEnum.ObjectCreatedAll);
    topicConfiguration1.FilterRules.Add(filterRule1);
    FilterRule filterRule2 = new FilterRule();
    filterRule2.Name = FilterNameEnum.Suffix;
    filterRule2.Value = ".jpg";
    TopicConfiguration topicConfiguration2 = new TopicConfiguration();
    topicConfiguration2.Id = "Id002";
    topicConfiguration2.Topic = "your topic2 URN";
    topicConfiguration2.Events.Add(EventTypeEnum.ObjectCreatedAll);
    topicConfiguration2.FilterRules.Add(filterRule2);
    NotificationConfiguration notificationConfiguration = new NotificationConfiguration();
    notificationConfiguration.TopicConfigurations.Add(topicConfiguration1);
    notificationConfiguration.TopicConfigurations.Add(topicConfiguration2);
