# Introduction
A RocketMQ client for golang supportting producer and consumer.
# Import package
import "github.com/sevenNt/rocketmq"
# Getting started
### Getting message with consumer
```
group := "dev-VodHotClacSrcData"
topic := "canal_vod_collect__video_collected_count_live"
var timeSleep = 30 * time.Second
conf := &rocketmq.Config{
Nameserver: "192.168.7.101:9876;192.168.7.102:9876;192.168.7.103:9876",
ClientIp: "192.168.1.23",
InstanceName: "DEFAULT",
}
consumer, err := rocketmq.NewDefaultConsumer(consumerGroup, consumerConf)
if err != nil {
return err
}
consumer.Subscribe(consumerTopic, "*")
consumer.RegisterMessageListener(
func(msgs []*MessageExt) error {
for i, msg := range msgs {
fmt.Println("msg", i, msg.Topic, msg.Flag, msg.Properties, string(msg.Body))
}
fmt.Println("Consume success!")
return nil
})
consumer.Start()
time.Sleep(timeSleep)
```
### Sending message with producer
- Synchronous sending
```
group := "dev-VodHotClacSrcData"
topic := "canal_vod_collect__video_collected_count_live"
conf := &rocketmq.Config{
Nameserver: "192.168.7.101:9876;192.168.7.102:9876;192.168.7.103:9876",
ClientIp: "192.168.1.23",
InstanceName: "DEFAULT",
}
producer, err := rocketmq.NewDefaultProducer(group, conf)
producer.Start()
if err != nil {
return errors.New("NewDefaultProducer err")
}
msg := NewMessage(topic, []byte("Hello RocketMQ!")
if sendResult, err := producer.Send(msg); err != nil {
return errors.New("Sync sending fail!")
} else {
fmt.Println("Sync sending success!, ", sendResult)
}
```
- Asynchronous sending
```
group := "dev-VodHotClacSrcData"
topic := "canal_vod_collect__video_collected_count_live"
conf := &rocketmq.Config{
Nameserver: "192.168.7.101:9876;192.168.7.102:9876;192.168.7.103:9876",
ClientIp: "192.168.1.23",
InstanceName: "DEFAULT",
}
producer, err := rocketmq.NewDefaultProducer(group, conf)
producer.Start()
if err != nil {
return err
}
msg := NewMessage(topic, []byte("Hello RocketMQ!")
sendCallback := func() error {
fmt.Println("I am callback")
return nil
}
if err := producer.SendAsync(msg, sendCallback); err != nil {
return err
} else {
fmt.Println("Async sending success!")
}
```
- Oneway sending
```
group := "dev-VodHotClacSrcData"
topic := "canal_vod_collect__video_collected_count_live"
conf := &rocketmq.Config{
Nameserver: "192.168.7.101:9876;192.168.7.102:9876;192.168.7.103:9876",
ClientIp: "192.168.1.23",
InstanceName: "DEFAULT",
}
producer, err := rocketmq.NewDefaultProducer(group, conf)
producer.Start()
if err != nil {
return err
}
msg := NewMessage(topic, []byte("Hello RocketMQ!")
if err := producer.SendOneway(msg); err != nil {
return err
} else {
fmt.Println("Oneway sending success!")
}
```
