Go Redis Queue: Setup & Usage Guide

In Go language, using a Redis queue can be achieved by following these steps:

1. To install the redis-go client library: Start by installing the Redis client library for Go language, which can be done using github.com/go-redis/redis library.

go get github.com/go-redis/redis

1. Connect to Redis server: Establish a connection with a Redis server in a Go program.

import (
    "github.com/go-redis/redis"
    "fmt"
)

func main() {
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "", // no password
        DB:       0,  // use default DB
    })

    pong, err := client.Ping().Result()
    fmt.Println(pong, err)
}

1. Utilize Redis queues: Implement Redis’s list data structure as a queue.

import (
    "github.com/go-redis/redis"
    "fmt"
)

func main() {
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "", // no password
        DB:       0,  // use default DB
    })

    // 从队列左侧插入数据
    err := client.LPush("my_queue", "item1", "item2").Err()
    if err != nil {
        panic(err)
    }

    // 从队列右侧弹出数据
    val, err := client.RPop("my_queue").Result()
    if err != nil {
        panic(err)
    }
    fmt.Println(val)
}

By following the above steps, you can implement a message queue functionality in Go using a Redis queue.
