[Go] golang连接redis测试

go-redis的使用
1.下载代码到GOPATH环境变量指定的目录
比如我的是进入目录D:\golang\code\src\github.com\go-redis,执行git clone https://github.com/go-redis/redis.git

2.redis设置过期时间的命令是: setex name 10 taoshihan ;设置10秒过期

 

package main

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

func main() {
	ExampleNewClient()
	ExampleClient()
}

//ping pong测试
func ExampleNewClient() {
	client := redis.NewClient(&redis.Options{
		Addr:     "115.159.128.112:6379",Password: "",// no password set
		DB:       0,// use default DB
	})

	pong,err := client.Ping().Result()
	fmt.Println(pong,err)
	// Output: PONG <nil>
}

//set和get测试
func ExampleClient() {
	client := redis.NewClient(&redis.Options{
		Addr:     "115.159.128.112:6379",// use default DB
	})
	//第三个参数是过期时间
	err := client.Set("name","taoshihan",10*time.Second).Err()
	if err != nil {
		panic(err)
	}

	val,err := client.Get("name").Result()
	if err != nil {
		panic(err)
	}
	fmt.Println("name:",val)
	//检测key是否存在
	val2,err := client.Get("key2").Result()
	if err == redis.Nil {
		fmt.Println("key2 不存在")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2",val2)
	}
}
