              {{errorMsg.message}}
          
        

3.2后端

 生成短信验证码，保存在redis中

@RestController
@RequestMapping("/sms")
public class SmsController {
    @Resource
    private StringRedisTemplate stringRedisTemplate ;

    @PostMapping("/code")
    public BaseResult sendSms(@RequestBody TbUser user){
        //获取当前毫秒值
        long start = System.currentTimeMillis();
        try {
            //发送短信
            //1.生成验证码，随机4位数
            String code = RandomStringUtils.randomNumeric(4);
            System.out.println("短信验证码：" + code);
            //存放在redis中
            stringRedisTemplate.opsForValue().set("smsPhone"+user.getTelephone(),code,1, TimeUnit.HOURS);
            //发送短信
            SendSmsResponse smsResponse = SmsUtil.sendSms(user.getTelephone(), user.getUserName(), code, "", "");
            if ("OK".equalsIgnoreCase(smsResponse.getCode())){

        } catch (ClientException e) {
            //获取结束时间毫秒值
            long end = System.currentTimeMillis();
            System.out.println(end -start);
            return BaseResult.error("短信发送失败！");
        }
    }

}

            }
        }

        //登录对用户名和密码进行判断
