    public static void main(String[] args) {

        System.out.println("请用户输入一个手机号，此时会返回一个生成的验证码");
        String userPhone = scanner.next();
        String generateCode = generateNewCode(userPhone);
        System.out.println(generateCode);
        System.out.println("请输入您收到的验证码信息");
        String userInputCode = scanner.next();
        // 验证用户手动输入的数字 与 redis中的该手机号对应的验证码是否一致，是则提示验证成功，否则提示验证失败
        Verify(generateCode, userInputCode, userPhone);
    }

    // 生成当前最新验证码
    private static String generateNewCode(String input) {
        Jedis jedis = new Jedis("127.0.0.1", 6379);
        jedis.auth("你的密码");

        Random random = new Random();
        StringBuilder generageCode = new StringBuilder();
        for (int i = 0; i < 6; i++) {
            generageCode.append(random.nextInt(10));
        }

        Long Usercount = jedis.hincrBy(input, "Verify" + input + ":count", 1);
        jedis.hset(input, "Verify" + input + ":count", String.valueOf(Usercount));

        }
        if (Integer.parseInt(count) > 3) {
            System.out.println("您今日已超过三次验证，明天再来吧~");
        }
        if (myInput.equals(generateCode) && Integer.parseInt(count) <= 3) {
            System.out.println("验证成功");
            jedis.close();
            return;
        }
        System.out.println("验证失败");

    }
