我是使用docker拉取redis镜像然后挂载本地磁盘(csdn一搜就有)
# 连接
```go
package main

import (
	"context"
	"fmt"
	"github.com/redis/go-redis/v9"
	"time"
)

func main() {
	ctx := context.Background()
	rdb := redis.NewClient(&redis.Options{
		Addr:     "localhost:6379",
		Password: "",
		DB:       0,
	})
    //键名是name,键值是123,10s后过期(过期是键跟键值全删除,不是mysql那种软删除)
	err := rdb.Set(ctx, "name", "123", 10*time.Second).Err()
	if err != nil {
		panic(err)
	}
    //通过键名访问键值
	val, err := rdb.Get(ctx, "name").Result()
	if err != nil {
		panic(err)
	}

	val2, err := rdb.Get(ctx, "key2").Result()
	if err == redis.Nil {
		fmt.Println("key2 does not exist")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2", val2)
	}
	fmt.Println("name", val)
    /*
    C:GoLand\___go_build_RedisTest_go.exe
        key2 does not exist
        name 123
    */
    //panic的会被defer,最后执行,所以先打印key2不存在

}
