redis实现手机验证码功能

实现功能

1、输入手机号，点击发送后随机生成6位数字码，2分钟有效
2、输入验证码，点击验证，返回成功或失败
3、每个手机号每天只能输入3次

具体实现

package com.ricky.jedis;

import redis.clients.jedis.Jedis;

import java.util.Random;

public class PhoneCode {
    
    

    public static void main(String[] args) {
    
    

        //verifyCode("13678765435");
        getRedisCode("13678765435","863820");

    }

    // 1.生成验证码
    public static String getCode() {
    
    

        Random random = new Random();
        String code = "";

        for (int i = 0; i < 6; i++) {
    
    
            int rand = random.nextInt(10);
            code += rand;
        }

        return code;
    }

    // 验证码放入redis中，设置发送次数及过期时间
    public static void verifyCode(String phone) {
    
    
   		//连接redis
        Jedis jedis = new Jedis("192.168.38.128", 6379);
        jedis.auth("123456");

        // 手机发送次数key
        String countKey = "VerifyCode" + phone + ":count";
        // 验证码key
        String codeKey = "VerifyCode" + phone + ":code";

        String count = jedis.get(countKey);
        if (count == null) {
    
    
            jedis.setex(countKey, 24 * 60 * 60, "1");
        } else if (Integer.parseInt(count) < 3) {
    
    
            jedis.incr(countKey);
        } else {
    
    
            System.out.println("今天发送次数已超过三次！！");
        }
		//发送验证码放到redis里面
        String vcode = getCode();
        jedis.setex(codeKey, 120, vcode);
        jedis.close();
    }

    // 3.验证码校验
    public static void getRedisCode(String phone, String code) {
    
    
    	// 从redis获取验证码
        Jedis jedis = new Jedis("192.168.38.128", 6379);
        // redis密码
        jedis.auth("123456");
        //验证码key
        String codeKey = "VerifyCode" + phone + ":code";
        String redisCode = jedis.get(codeKey);
       
        if (redisCode.equals(code)) {
    
    
            System.out.println("成功");
        } else {
    
    
            System.out.println("失败");
        }
		 jedis.close();

    }
