GO获取rabbitMQ
go get github.com/streadway/amqp
1、创建连接
1
2
3
| conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/")
failOnError(err, "Failed to connect to RabbitMQ")
defer conn.Close()
|
2、创建管道
1
2
3
| ch, err := conn.Channel()
failOnError(err,"Failed to open a channel")
defer ch.Close()
|
3、创建queueDeclare这一步相当于设定一个key 设置一个queue的key

| q,err := ch.QueueDeclare(
"queue",
true,
false,
false,
false,
nil,
)
failOnError(err,"Failed To declare a queue")
|
4、存值调用

| body := `定义value值将值push到rabbitmq中`
err = ch.Publish("",q.Name,false,false,amqp.Publishing{
ContentType: "texp/plain",
Body: []byte(body),
})
|
5、取值调用

| msgs, err := ch.Consume(
q.Name, // queue
"", // consumer
true, // auto-ack
false, // exclusive
false, // no-local
false, // no-wait
nil, // args
)
failOnError(err, "Failed to register a consumer")
forever := make(chan bool)
go func() {
for d := range msgs {
log.Printf("Received a message: %s", d.Body)
}
}()
log.Printf(" [*] Waiting for messages. To exit press CTRL+C")
<-forever

6、task_work存值

| err = ch.Publish(
"",
q.Name,
false,
false,
amqp.Publishing{
ContentType: "text/plain",
DeliveryMode: amqp.Persistent,
Body: []byte(body),
},
)
|
7、work取值 可这只多个worker执行task队列

| err = ch.Qos(

false,
)
failOnError(err,"Failed to Set Qos")
msgs, err := ch.Consume(
q.Name, // queue
"", // consumer
false, // auto-ack
false, // exclusive
false, // no-local
false, // no-wait
nil, // args
)
failOnError(err,"Failed to regster a consumer")
forever:= make(chan bool)
go func() {
for d := range msgs {
log.Printf("Received a message: %s", d.Body)
dot_count := bytes.Count(d.Body, []byte("."))
t := time.Duration(dot_count)
time.Sleep(t * time.Second)
d.Ack(false)
}
}()
