做车品的网站/甘肃搜索引擎网络优化

1，先发短信
2，给手机号设置一个标识，为的是不允许重复发送，我用的是前后端分离的项目，所以代码中不会返回404,500，之类的。

  @Autowiredprivate RedisTemplate<String, String> redisTemplate;@PostMapping("/sms")
public ResponseEntity<BaseResult> sendSms(@RequestBody User user) {BaseResult br = null;try {String mobile = user.getMobile();String code = GetRandomCodeUtil.getNumber();String redisCode = redisTemplate.opsForValue().get(mobile);if (redisCode != null) {br = new BaseResult(1, "验证码在30分钟内只能发送一次");return ResponseEntity.ok(br);}//SmsUtil.sendSms(mobile, code);System.out.println(code);// 30分钟内只能发送一次redisTemplate.opsForValue().set(mobile, code, 30, TimeUnit.MINUTES);br = new BaseResult(0, "成功");return ResponseEntity.ok(br);} catch (Exception e) {e.printStackTrace();br = new BaseResult(1, "失败");return ResponseEntity.ok(br);}
}redisTemplate.opsForValue().set(mobile,code,30,TimeUnit.MINUTES);return null;
}

测试，OK
