The GO language operates Redis

  • From redis.cn client -go language – select Redigo – view API: godoc.org/github.com/…

  • It is mainly divided into 3 categories:

    1. Connecting to a Database
      • In the API documentation, everything starts with Dial
    2. Operating database
      • The Do() function
      • The Send() function can be used with the Flush() and Receive() functions
    3. Reply assistant
      • Equivalent to “type assertion”. Depending on the specific data type used, the call is selected
      • Identify the interface{} returned by the DO function as a concrete type

  • Test cases:

package main

import (
	"fmt"
	"github.com/gomodule/redigo/redis"
)

func main(a) {
	// 1. Connect to the database
	conn, err := redis.Dial("tcp".": 6379")
	iferr ! =nil {
		fmt.Println("redis.Dial err: ", err)
		return
	}
	defer conn.Close()

	// 2. Operate the database
	reply, err := conn.Do("set"."test"."yaxuan")

	// 3. Revert helper class functions -- identified as concrete data types
	r, e := redis.String(reply, err)
	fmt.Println(r, e)
}
