两个都是非常优秀的redisclient库,也是redis官网上推荐,笔者选择是的是go-redis,因为go-redis封装了redis的大部分命令,不用关心redis的命令的细节,直接调用相应接口就行;redigo是基于命令的,发送一个命令,然后在解析reply;所以相对而言,笔者觉得go-redis接口更友好;
这里也稍微做个广告,如果有朋友是用c++的,可以尝试下笔者开源的一个c++版的redisclient:redis_cpp, 跟go-redis类似,封装了redis大部分的命令,支持redis standalone, sentinel, cluster mode, 接口友好好用
1. go-redis的安装
go get https://github.com/go-redis/redis
2. 测试代码
// redis_test project main.gopackage main import ( "fmt" "time" "github.com/go-redis/redis") func err_handler(err error) { fmt.Printf("err_handler, error:%s\n", err.Error()) panic(err.Error()) } func standalon_redis_test() { fmt.Printf("standalon_redis_test") client := redis.NewClient(&redis.Options{ Addr: "localhost:6379", Password: "", DB: 0, }) defer client.Close() pong, err := client.Ping().Result() if err != nil { fmt.Printf("ping error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("ping result: %s\n", pong) fmt.Printf("----------------------------------------\n") // set / get test fmt.Printf("set/get test\n") err = client.Set("foo", "bar", 0).Err() if err != nil { fmt.Printf("try set key[foo] to value[bar] error[%s]\n", err.Error()) err_handler(err) } err = client.Set("foo1", "bar1", time.Hour*2).Err() if err != nil { fmt.Printf("try set key[foo1] to value[bar1] error[%s]\n", err.Error()) err_handler(err) } // get value value, err := client.Get("foo").Result() if err != nil { fmt.Printf("try get key[foo] error[%s]\n", err.Error()) // err_handler(err) } fmt.Printf("key[foo]'s value is %s\n", value) value, err = client.Get("foo1").Result() if err != nil { fmt.Printf("try get key[foo1] error[%s]\n", err.Error()) // err_handler(err) } fmt.Printf("key[foo1]'s value is %s\n", value) value, err = client.Get("foo2").Result() if err != nil { fmt.Printf("try get key[foo2] error[%s]\n", err.Error()) // err_handler(err) } fmt.Printf("key[foo2]'s value is %s\n", value) // get ttl duration, err := client.TTL("foo").Result() if err != nil { fmt.Printf("try get ttl of key[foo] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("key[foo]' ttl is [%s] %fs\n", duration.String(), duration.Seconds()) duration, err = client.TTL("foo1").Result() if err != nil { fmt.Printf("try get ttl of key[foo1] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("key[foo1]' ttl is [%s] %ds\n", duration.String(), int64(duration.Seconds())) fmt.Printf("----------------------------------------\n") // list test fmt.Printf("list test\n") err = client.RPush("tqueue", "tmsg1").Err() if err != nil { fmt.Printf("rpush list[tqueue] error[%s]\n", err.Error()) err_handler(err) } list_len, err := client.LLen("tqueue").Result() if err != nil { fmt.Printf("try get len of list[tqueue] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("len of list[tqueue] is %d\n", list_len) result, err := client.BLPop(time.Second*1, "tqueue").Result() if err != nil { fmt.Printf("blpop list[tqueue] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("blpop list[tqueue], value[%s]\n", result[1]) fmt.Printf("----------------------------------------\n") fmt.Printf("hmap test\n") err = client.HSet("tmap", "1", "f1").Err() if err != nil { fmt.Printf("try hset map[tmap] field[1] error[%s]\n", err.Error()) err_handler(err) } err = client.HSet("tmap", "2", "f2").Err() if err != nil { fmt.Printf("try hset map[tmap] field[2] error[%s]\n", err.Error()) err_handler(err) } kv_map := make(map[string]interface{}) kv_map["3"] = "f3" kv_map["4"] = "f4" err = client.HMSet("tmap", kv_map).Err() if err != nil { fmt.Printf("try mset map[tmap] field[3] field[4] error[%s]\n", err.Error()) err_handler(err) } map_len, err := client.HLen("tmap").Result() if err != nil { fmt.Printf("try get len of map[tmap] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("len of map[tmap] is %d\n", map_len) // get map value value, err = client.HGet("tmap", "1").Result() if err != nil { fmt.Printf("try get field[1] value of map[tmap] error[%s]\n", err.Error()) err_handler(err) } fmt.Printf("field[1] value of map[tmap] is %s\n", value) // hgetall result_kv, err := client.HGetAll("tmap").Result() if err != nil { fmt.Printf("try hgetall map[tmap] error[%s]\n", err.Error()) err_handler(err) } for k, v := range result_kv { fmt.Printf("map[tmap] %s = %s\n", k, v) } fmt.Printf("----------------------------------------\n") fmt.Printf("pubsub test\n") pubsub := client.Subscribe("test_channel") _, err = pubsub.Receive() if err != nil { fmt.Printf("try subscribe channel[test_channel] error[%s]\n", err.Error()) err_handler(err) } // go channel to used to receive message ch := pubsub.Channel() // publish a message err = client.Publish("test_channel", "hello").Err() if err != nil { fmt.Printf("try publish message to channel[test_channel] error[%s]\n", err.Error()) err_handler(err) } time.AfterFunc(time.Second*2, func() { _ = pubsub.Close() }) // consume message for { msg, ok := <-ch if !ok { break } fmt.Printf("recv message[%s] from channel[%s]\n", msg.Payload, msg.Channel) } } func main() { fmt.Println("redis_test!") standalon_redis_test() }
