[TOC] > [github](https://github.com/go-redis/redis/) ## 安裝 go 必須支持mod ``` go get github.com/go-redis/redis/v7 ``` ## 實例 ### hello word ``` func ExampleNewClient() { client := redis.NewClient(&redis.Options{ Addr: "localhost:6379", Password: "", // no password set DB: 0, // use default DB }) pong, err := client.Ping().Result() fmt.Println(pong, err) // Output: PONG <nil> } func ExampleClient() { client := redis.NewClient(&redis.Options{ Addr: "localhost:6379", Password: "", // no password set DB: 0, // use default DB }) err := client.Set("key", "value", 0).Err() if err != nil { panic(err) } val, err := client.Get("key").Result() if err != nil { panic(err) } fmt.Println("key", val) val2, err := client.Get("key2").Result() if err == redis.Nil { fmt.Println("key2 does not exist") } else if err != nil { panic(err) } else { fmt.Println("key2", val2) } // Output: key value // key2 does not exist } ``` ### 管道 管道的數據不可中途獲取 ``` func ExampleClient_TxPipeline() { pipe := rdb.TxPipeline() incr := pipe.Incr("tx_pipeline_counter") pipe.Expire("tx_pipeline_counter", time.Hour) //pipe.Get() //... _, err := pipe.Exec() fmt.Println(incr.Val(), err) //數據得最后獲取 } ```
