1. 调用的时序图

2. 安装redis

因为短息验证码是存在redis服务中，所以需要安装redis，redis的安装比较简单可以自行安装即可。

3.  启动redis

4. 监听端口代码

package main
    
    import (
    	"fmt"
    	"log"
    	"net/http"
    	"src/login"
    )
    
    func main() {
    	fmt.Println("server start")
    	http.HandleFunc("/login", loginByPassword)
    	// 获取验证码
    	http.HandleFunc("/getPhoneCode", getPhoneCode)
    	// 校验验证码
    	http.HandleFunc("/checkCode", checkCode)
    	if err := http.ListenAndServe(":8888", nil); err != nil{
    		log.Fatal("Server error", err)
    	}
    	fmt.Println("server out")
    }
    
    func loginByPassword(w http.ResponseWriter, r *http.Request)  {
    	login.Login(w, r)
    }
    
    func getPhoneCode(w http.ResponseWriter, r *http.Request)  {
    	login.GetPhoneCode(w, r)
    }
    
    func checkCode(w http.ResponseWriter, r *http.Request)  {
    	login.CheckCode(w, r)
    }

5. 获取验证码及调用短息服务

// 获取手机号验证码
    func GetPhoneCode(w http.ResponseWriter, r *http.Request)  {
    	var result pojo.Resp
    	query := r.URL.Query()
    	phone := query["phone"][0]
    	// 1.手机号校验
    	// 2.获取随机验证码
    	code := randCode()
    	// 3. redis记录
    	redis.SetMini(phone, code,5)
    	// 4. 异步发送验证码
    	go func() {
    		// time.Sleep(time.Duration(10)*time.Second)
    		send(phone, code)
    	}()
    	// 5.返回
    	result.Msg = "success"
    	result.Data = code
    	if err := json.NewEncoder(w).Encode(result); err != nil {
    		log.Fatal(err)
    	}
    }

6. 随机生成6位数短息验证码

// 6位随机验证码
    func randCode() string {
    	rnd := rand.New(rand.NewSource(time.Now().UnixNano()))
    	rndCode := fmt.Sprintf("%06v", rnd.Int31n(1000000))
    	fmt.Println(rndCode)
    	return rndCode
    }

7. redis的连接

package redis
    import (
    	"log"
    	"strconv"
    	"github.com/go-redis/redis"
    	"fmt"
    )
    
    var server = "127.0.0.1"
    var port = 6379
    var password = ""
    var db = 0
    // 注意int转字符串
    var addr  = server + ":" + strconv.Itoa(port)
    
    /*
     基于go-redis
     github地址:https://github.com/go-redis/redis
     redis连接demo，连接数等自行设置
    */
    func  GetClient() (clint *redis.Client) {
    	fmt.Println(addr)
    	fmt.Println(port)
    	client := redis.NewClient(&redis.Options{
    		Addr:     addr,
    		Password: password, // no password set
    		DB:       db,  // use default DB
    	})
    
    	pong, err := client.Ping().Result()
    	log.Println(pong, err)
    	return client
    }

8. redis的工具类型如get或set

package redis
    
    import (
    	"github.com/go-redis/redis"
    	_ "github.com/go-redis/redis"
    	"time"
    )
    
    /*
     基于go-redis
     github地址:https://github.com/go-redis/redis
     设置小时demo
    */
    func SetHour() (result *redis.StatusCmd) {
    	client := GetClient()
    	// 注意time.Hour 要乘以一个具体的数值
    	set := client.Set("hour", "3个小时", time.Hour*3)
    	return set
    }
    
    /*
     基于go-redis
     github地址:https://github.com/go-redis/redis
     设置分钟demo
    */
    func SetMini(key string, value string, i int64) (result *redis.StatusCmd) {
    	client := GetClient()
    	// 注意time.Minute 要乘以一个具体的数值
    	set := client.Set(key, value, time.Duration(i) * time.Minute)
    	return set
    }
    
    /*
     基于go-redis
     github地址:https://github.com/go-redis/redis
     get的demo
    */
    func Get(key string) string {
    	c := GetClient()
    	get := c.Get(key)
    	result, _ := get.Result()
    	return result
    }

9. 基本的代码如上，如有疑问或需要源码欢迎留言沟通。
