Quick Start

func StartAndSubscribeOpenSergoConfig() error {
	// Set OpenSergo console logger (optional)
	logging.NewConsoleLogger(logging.InfoLevel, logging.SeparateFormat, true)
	// Set OpenSergo file logger (optional)
	// logging.NewFileLogger("./opensergo-universal-transport-service.log", logging.InfoLevel, logging.JsonFormat, true)

	// Create an OpenSergoClient.
	openSergoClient, err := client.NewOpenSergoClient("127.0.0.1", 10246)
	if err != nil {
		return err
	}

	// Start the OpenSergoClient.
	err = openSergoClient.Start()
	if err != nil {
		return err
	}

	// Create a SubscribeKey for FaultToleranceRule.
	faultToleranceSubscribeKey := model.NewSubscribeKey("default", "foo-app", configkind.ConfigKindRefFaultToleranceRule{})
	// Create a Subscriber.
	sampleFaultToleranceRuleSubscriber := &samples.SampleFaultToleranceRuleSubscriber{}
	// Subscribe data with the key and subscriber.
	err = openSergoClient.SubscribeConfig(*faultToleranceSubscribeKey, api.WithSubscriber(sampleFaultToleranceRuleSubscriber))
	if err != nil {
		return err
	}

	// Create a SubscribeKey for RateLimitStrategy.
	rateLimitSubscribeKey := model.NewSubscribeKey("default", "foo-app", configkind.ConfigKindRefRateLimitStrategy{})
	// Subscribe data with the key, but without a subscriber.
	// We may pull the data from the data cache later.
	err = openSergoClient.SubscribeConfig(*rateLimitSubscribeKey))

	return err
}

Components

logger mechanism

In OpenSergo Go SDK, we provide a fundamental logger mechanism, which has the following features:

• provider a universal Logger interface. Users may register customized logger adapters.
• provider a default Logger implementation, which can be used directory.
• provider a default Logger format assembler, which can assemble two formatters of log message.
