golang operation redis： write in 、 Read hash Type data

Code

package main
import (
	"fmt"
	"github.com/garyburd/redigo/redis" // introduce redis package 
)

func main() {
    
	// adopt go  towards redis  Write data and read data 
	//1.  link to redis
	conn, err := redis.Dial("tcp", "127.0.0.1:6379")
	if err != nil {
    
		fmt.Println("redis.Dial err=", err)
		return 
	}
	defer conn.Close() // close ..

	//2.  adopt go  towards redis Write data  string [key-val]
	_, err = conn.Do("HSet", "user01", "name", "john")
	if err != nil {
    
		fmt.Println("hset err=", err)
		return 
	}

	_, err = conn.Do("HSet", "user01", "age", 18)
	if err != nil {
    
		fmt.Println("hset err=", err)
		return 
	}

	//3.  adopt go  towards redis Reading data  

	r1, err := redis.String(conn.Do("HGet","user01", "name"))
	if err != nil {
    
		fmt.Println("hget err=", err)
		return 
	}

	r2, err := redis.Int(conn.Do("HGet","user01", "age"))
	if err != nil {
    
		fmt.Println("hget err=", err)
		return 
	}

	// Because back  r yes  interface{}
	// because  name  The corresponding value is string , So we need to switch 
	//nameString := r.(string)

	fmt.Printf(" operation ok r1=%v r2=%v \n", r1, r2)
}
