一、短信验证码（阿里云短信服务）

@Data
@ConfigurationProperties(prefix = "spring.cloud.alicloud.sms")
@Component
public class SmsComponent {private String host;private String path;private String skin;private String sign;private String appCode;public String sendSmsCode(String phone, String code){String method = "GET";Map<String, String> headers = new HashMap<String, String>();//最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105headers.put("Authorization", "APPCODE " + this.appCode);Map<String, String> querys = new HashMap<String, String>();querys.put("code", code);querys.put("phone", phone);querys.put("skin", this.skin);querys.put("sign", this.sign);HttpResponse response = null;try {response = HttpUtils.doGet(this.host, this.path, method, headers, querys);//获取response的bodyif(response.getStatusLine().getStatusCode() == 200){return EntityUtils.toString(response.getEntity());}} catch (Exception e) {e.printStackTrace();}return "fail_" + response.getStatusLine().getStatusCode();}
}

二、验证码防刷校验

@Controller
@RequestMapping("/sms")
public class SmsSendController {@Autowiredprivate SmsComponent smsComponent;/*** 提供给别的服务进行调用的*/@GetMapping("/sendcode")public R sendCode(@RequestParam("phone") String phone, @RequestParam("code") String code){if(!"fail".equals(smsComponent.sendSmsCode(phone, code).split("_")[0])){return R.ok();}return R.error(BizCodeEnum.SMS_SEND_CODE_EXCEPTION.getCode(), BizCodeEnum.SMS_SEND_CODE_EXCEPTION.getMsg());}
}

🚩思路是将每一次发的验证码存在redis，并且加上存放的当前时间，下一次发验证码请求时先判断当前时间-上一次存放时间，如果小于60秒，返回错误，否则才发验证码请求

	/** 接收到一个手机号，在此处生成验证码和缓存，然后转给第三方服务让他给手机发验证按* */@ResponseBody@GetMapping("/sms/sendcode")public R sendCode(@RequestParam("phone") String phone){//  TODO 接口防刷(冷却时长递增)，redis缓存 sms:code:电话号String redisCode = stringRedisTemplate.opsForValue().get(AuthServerConstant.SMS_CODE_CACHE_PREFIX + phone);// 如果不为空，返回错误信息if(null != redisCode && redisCode.length() > 0){long CuuTime = Long.parseLong(redisCode.split("_")[1]);if(System.currentTimeMillis() - CuuTime < 60 * 1000){ // 60sreturn R.error(BizCodeEnum.SMS_CODE_EXCEPTION.getCode(), BizCodeEnum.SMS_CODE_EXCEPTION.getMsg());}}// 生成验证码String code = UUID.randomUUID().toString().substring(0, 6);String redis_code = code + "_" + System.currentTimeMillis();// 缓存验证码stringRedisTemplate.opsForValue().set(AuthServerConstant.SMS_CODE_CACHE_PREFIX + phone, redis_code , 10, TimeUnit.MINUTES);try {// 调用第三方短信服务return thirdPartFeignService.sendCode(phone, code);} catch (Exception e) {log.warn("远程调用不知名错误 [无需解决]");}return R.ok();}

三、注册环境

	@PostMapping("/register")public String register(@Valid UserRegisterVo userRegisterVo,BindingResult result,RedirectAttributes redirectAttributes){if(result.hasErrors()){// 将错误属性与错误信息一一封装Map<String, String> errors = result.getFieldErrors().stream().collect(Collectors.toMap(FieldError::getField, fieldError -> fieldError.getDefaultMessage()));// addFlashAttribute 这个数据只取一次redirectAttributes.addFlashAttribute("errors", errors);return "redirect:http://auth.gulimall.com/reg.html";}

	/*** TODO 重定向携带数据,利用session原理 将数据放在sessoin中 取一次之后删掉** TODO 1. 分布式下的session问题* 校验* RedirectAttributes redirectAttributes ： 模拟重定向带上数据*/@PostMapping("/register")public String register(@Valid UserRegisterVo userRegisterVo,BindingResult result,RedirectAttributes redirectAttributes){if(result.hasErrors()){// 将错误属性与错误信息一一封装Map<String, String> errors = result.getFieldErrors().stream().collect(Collectors.toMap(FieldError::getField, FieldError::getDefaultMessage));// addFlashAttribute 这个数据只取一次redirectAttributes.addFlashAttribute("errors", errors);return "redirect:http://auth.gulimall.com/reg.html";}// 开始注册 调用远程服务// 1.校验验证码String code = userRegisterVo.getCode();String redis_code = stringRedisTemplate.opsForValue().get(AuthServerConstant.SMS_CODE_CACHE_PREFIX + userRegisterVo.getPhone());if(!StringUtils.isEmpty(redis_code)){// 验证码通过if(code.equals(redis_code.split("_")[0])){// 删除验证码stringRedisTemplate.delete(AuthServerConstant.SMS_CODE_CACHE_PREFIX + userRegisterVo.getPhone());// 调用远程服务进行注册R r = memberFeignService.register(userRegisterVo);if(r.getCode() == 0){// 注册成功，去登录return "redirect:http://auth.gulimall.com/login.html";}else{Map<String, String> errors = new HashMap<>();errors.put("msg",r.getData("msg",new TypeReference<String>(){}));// 数据只需要取一次redirectAttributes.addFlashAttribute("errors",errors);return "redirect:http://auth.gulimall.com/reg.html";}}else{Map<String, String> errors = new HashMap<>();errors.put("code", "验证码错误");// addFlashAttribute 这个数据只取一次redirectAttributes.addFlashAttribute("errors", errors);return "redirect:http://auth.gulimall.com/reg.html";}}else{Map<String, String> errors = new HashMap<>();errors.put("code", "验证码错误");// addFlashAttribute 这个数据只取一次redirectAttributes.addFlashAttribute("errors", errors);return "redirect:http://auth.gulimall.com/reg.html";}}
