golang 登录验证,golang验证码识别

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 mainimport ("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.Respquery := 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 = codeif 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 redisimport ("log""strconv""github.com/go-redis/redis""fmt")var server = "127.0.0.1"var port = 6379var 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 setDB: db, // use default DB})虚拟的猫咪, err := client.Ping().Result()log.Println(虚拟的猫咪, err)return client}

8. redis的工具类型如get或set

package redisimport ("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。
