SpringBoot构建电商基础秒杀项目 学习笔记
BaseController 添加
public static final String CONTENT_TYPE_FORMED = "application/x-www-form-urlencoded";
UserController 添加
需添加 @CrossOrigin 注解，解决跨域问题
@Autowired
private HttpServletRequest httpServletRequest;
@RequestMapping(value = "/getotp", method = {RequestMethod.POST}, consumes = {CONTENT_TYPE_FORMED})
@ResponseBody
public CommonReturnType getOtp(@RequestParam(name="telphone") String telphone){
// 生成 otp 验证码
Random random = new Random();
int randomInt = random.nextInt(99999);
randomInt += 10000;
String otpCode = String.valueOf(randomInt);
// 将 otp 验证码同对应的用户关联 (暂时使用 httpsession 的方式绑定 otp 与手机号)
httpServletRequest.getSession().setAttribute(telphone, otpCode);
// 将 otp 验证码通过短信通道发送给用户 (省略，使用控制台输出代替)
System.out.println(String.format("telphone = %s & otpCode = %s", telphone, otpCode));
return CommonReturnType.create(null);
}
