Quick Example
The following Go snippet shows the minimal connect / publish / subscribe flow:
go
import mqtt "github.com/eclipse/paho.mqtt.golang"
opts := mqtt.NewClientOptions().
AddBroker("tcp://localhost:1883").
SetClientID("my-client").
SetUsername("admin").
SetPassword("robustmq")
client := mqtt.NewClient(opts)
client.Connect().Wait()
// Publish
client.Publish("test/topic", 0, false, "Hello RobustMQ!")
// Subscribe
client.Subscribe("test/topic", 0, func(_ mqtt.Client, msg mqtt.Message) {
fmt.Println(string(msg.Payload()))
