Operating NSQ Queue database in Golang

This is a creation in Article, where the information may have evolved or changed.

First in the local service run up, I use docker-compose, a sentence 6666

First create a new docker-compose.ymlversion: ' 2 ' services:  nsqlookupd:    image:nsqio/nsq    command:/NSQLOOKUPD    Ports:      -"192.168.9.111:4160:4160"      -"192.168.9.111:4161:4161"  nsqd:    image:nsqio/nsq    command :/nsqd--lookupd-tcp-address=nsqlookupd:4160    depends_on:      -nsqlookupd    ports:      -" 192.168.9.111:4150:4150 "      -" 192.168.9.111:4151:4151 "  nsqadmin:    image:nsqio/nsq    Command:/ Nsqadmin--lookupd-http-address=nsqlookupd:4161    depends_on:      -nsqlookupd    ports:      -" 192.168.9.111:4171:4171 "

And then the entire data ran.

Write a production message.

tproducter.gopackage Mainimport ("Log" "GITHUB.COM/NSQIO/GO-NSQ" "Encoding/json" "StrConv") type person struct {IdintName String ageintnickname String}func Main () {config:=nsq. Newconfig () W,err:=nsq. Newproducer ("192.168.9.111:4150", config)ifErr! =Nil {log. Panic ("Could not create producer.")} defer w.stop () forI: =0;i<100;i++{p:=&person{} p.id=I p.name= "Jack" +StrConv. Itoa (i) P.nickname= "Luo" +StrConv. Itoa (i) P.age=I info,jerr:=JSON. Marshal (P) Err:=w.publish ("Write_test", info)ifErr!=nil | | Jerr! =Nil {log. Panic ("Could not connect.")}} w.stop () }

and write a consumer.

tconsumer.gopackage Mainimport ("Log" "GITHUB.COM/NSQIO/GO-NSQ" "Time"Func Main () {config:=nsq. Newconfig () Q,err:= nsq. Newconsumer ("Write_test", "ch", config)ifErr! =nil{Log. Panic ("Could not create consumer.")} defer Q.stop () Q.addhandler (nsq. Handlerfunc (func (Message*nsq. Message) error{log. Printf ("Got a message:%v"a string (message. Body) time. Sleep (5*Time . Second)returnnil})) //err = Q.CONNECTTONSQD ("192.168.9.111:32771");Err = Q.CONNECTTONSQD ("192.168.9.111:4150"); ifErr! =Nil {log. Panic ("Could Not Connect")} time. Sleep (3600*Time . Second)}

And then we're going to get 6.
