如何用Go语言和Redis实现数据缓存

$ sudo apt-get update
$ sudo apt-get install redis-server

$ go get GitHub.com/go-redis/redis/v8

import (
    "github.com/go-redis/redis/v8"
    "context"
)

func main() {
    ctx := context.Background()
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        PassWord: "", // Redis数据库密码，如果没有密码则为空
        DB:       0,  // 默认Redis数据库
    })

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

err := client.Set(ctx, "example", "value", 0).Err()
if err != nil {
    panic(err)
}

value, err := client.Get(ctx, "example").Result()
if err != nil {
    panic(err)
}
fmt.Println("example:", value)

err := client.Del(ctx, "example").Err()
if err != nil {
    panic(err)
}

import (
    "github.com/go-redis/redis/v8"
    "context"
)

func main() {
    ctx := context.Background()
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "",
        DB:       0,
    })

    err := client.Set(ctx, "example", "value", 0).Err()
    if err != nil {
        panic(err)
    }

    value, err := client.Get(ctx, "example").Result()
    if err != nil {
        panic(err)
    }
    fmt.Println("example:", value)

    err := client.Del(ctx, "example").Err()
    if err != nil {
        panic(err)
    }
}
