golang 中操作nsq隊列資料庫

這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

首先先在本地將服務跑起來，我用的是docker-compose ,一句話6666

先建立一個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"

　　然後整個資料就跑起來了

寫個生產訊息的

tproducter.gopackage mainimport(    "log"    "github.com/nsqio/go-nsq"    "encoding/json"    "strconv")type Person struct {    Id int    Name string    Age int    NickName string}func main() {    config :=nsq.NewConfig()    w,err :=nsq.NewProducer("192.168.9.111:4150",config)    if err !=nil {        log.Panic("Could not create producer.")    }    defer w.Stop()    for i :=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)        if err !=nil || jerr !=nil {            log.Panic("Could not connect.")        }    }    w.Stop()}

再寫個消費的

tconsumer.gopackage mainimport (    "log"    "github.com/nsqio/go-nsq"    "time")func main() {    config :=nsq.NewConfig()    q,err := nsq.NewConsumer("write_test","ch",config)    if err !=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",string(message.Body))        time.Sleep(5*time.Second)        return nil    }))    //err = q.ConnectToNSQD("192.168.9.111:32771");    err = q.ConnectToNSQD("192.168.9.111:4150");    if err !=nil {        log.Panic("Could not connect")    }    time.Sleep(3600*time.Second)}

然後就要以6起來了

/usr/local/go/bin/go run /Users/jackluo/Works/golang/src/nsq/tconsumer.go2017/08/29 15:29:45 INF    1 [write_test/ch] (192.168.9.111:4150) connecting to nsqd2017/08/29 15:29:45 Got a message: {"Id":0,"Name":"Jack0","Age":0,"NickName":"Luo0"}2017/08/29 15:29:50 Got a message: {"Id":1,"Name":"Jack1","Age":1,"NickName":"Luo1"}2017/08/29 15:29:55 Got a message: {"Id":2,"Name":"Jack2","Age":2,"NickName":"Luo2"}2017/08/29 15:30:00 Got a message: {"Id":3,"Name":"Jack3","Age":3,"NickName":"Luo3"}2017/08/29 15:30:05 Got a message: {"Id":4,"Name":"Jack4","Age":4,"NickName":"Luo4"}2017/08/29 15:30:10 Got a message: {"Id":5,"Name":"Jack5","Age":5,"NickName":"Luo5"}2017/08/29 15:30:15 Got a message: {"Id":6,"Name":"Jack6","Age":6,"NickName":"Luo6"}2017/08/29 15:30:20 Got a message: {"Id":7,"Name":"Jack7","Age":7,"NickName":"Luo7"}2017/08/29 15:30:25 Got a message: {"Id":8,"Name":"Jack8","Age":8,"NickName":"Luo8"}2017/08/29 15:30:30 Got a message: {"Id":9,"Name":"Jack9","Age":9,"NickName":"Luo9"}2017/08/29 15:30:35 Got a message: {"Id":10,"Name":"Jack10","Age":10,"NickName":"Luo10"}2017/08/29 15:30:40 Got a message: {"Id":11,"Name":"Jack11","Age":11,"NickName":"Luo11"}2017/08/29 15:30:45 Got a message: {"Id":12,"Name":"Jack12","Age":12,"NickName":"Luo12"}
