C端登录注册功能

项目结构

发送验证码

由于我们前面已经讲了很多后端代码相关内容了，相信大家学到这里的时候应该对代码很熟悉了，就不做详细讲解，看代码直接懂就好了

Controller

import com.bite.common.core.controller.BaseController;
import com.bite.common.core.domain.R;
import com.bite.friend.model.DTO.UserDTO;
import com.bite.friend.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/user")
public class UserController extends BaseController {@Autowiredprivate IUserService userService;//  /user/sendCode@PostMapping("sendCode")public R<Void> sendCode(@RequestBody UserDTO userDTO) {return toR(userService.sendCode(userDTO)) ;}
}

DTO

@Getter
@Setter
public class UserDTO {private String phone;private String code;
}

Service

我们这里首先对传过来的手机号进行验证验证，看是否符合一个手机号的格式，然后生成一个随机验证码，至于发送验证码，我们需要用到阿里云短信服务（但是，我们发现，阿里云的短信服务居然不允许个人使用了）

import cn.hutool.core.util.RandomUtil;
import com.bite.common.core.enums.ResultCode;
import com.bite.common.security.EXCEPTION.ServiceException;
import com.bite.friend.model.DTO.UserDTO;
import com.bite.friend.service.IUserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;import java.util.regex.Matcher;
import java.util.regex.Pattern;@Service
@Slf4j
public class UserServiceImpl implements IUserService {@Overridepublic int sendCode(UserDTO userDTO) {if (!checkPhone(userDTO.getPhone())) {throw new ServiceException(ResultCode.FAILED_USER_PHONE);}String phoneCodeKey = getPhoneCodeKey(userDTO.getPhone());Long expire = redisService.getExpire(phoneCodeKey, TimeUnit.SECONDS);if (expire != null && (phoneCodeExpiration * 60 - expire) < 60 ){throw new ServiceException(ResultCode.FAILED_FREQUENT);}//每天的验证码获取次数有一个限制  50次  第二天  计数清0 重新开始计数     计数  怎么存  存在哪//操作这个次数数据频繁   、 不需要存储、  记录的次数 有有效时间的（当天有效） redis  String  key：c:t:手机号//获取已经请求的次数  和50 进行比较     如果大于限制抛出异常。如果不大于限制，正常执行后续逻辑，并且将获取计数 + 1String codeTimeKey = getCodeTimeKey(userDTO.getPhone());Long sendTimes = redisService.getCacheObject(codeTimeKey, Long.class);if (sendTimes != null && sendTimes >= sendLimit) {throw new ServiceException(ResultCode.FAILED_TIME_LIMIT);}String code=RandomUtil.randomNumbers(6);System.out.println("密码："+code);redisService.setCacheObject(phoneCodeKey, code, phoneCodeExpiration, TimeUnit.MINUTES);redisService.increment(codeTimeKey);if (sendTimes == null) {  //说明是当天第一次发起获取验证码的请求long seconds = ChronoUnit.SECONDS.between(LocalDateTime.now(),LocalDateTime.now().plusDays(1).withHour(0).withMinute(0).withSecond(0).withNano(0));redisService.expire(codeTimeKey, seconds, TimeUnit.SECONDS);}return 1;}
}

我们这里需要保证几点：

1.检查这个手机号是否为正确的

2.获得当前验证码还剩多少秒，如果一分钟内有5次以上，则抛出异常

3.查看一天内发送了多少次，如果超过一定限度则抛出异常，每次发送后++；

mapper

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.bite.friend.model.User;public interface UserMapper  extends BaseMapper<User> {}

User

package com.bite.friend.model;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import com.bite.common.core.domain.BaseEntity;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import lombok.Getter;
import lombok.Setter;@Getter
@Setter
@TableName("tb_user")
public class User extends BaseEntity {@JsonSerialize(using = ToStringSerializer.class)@TableId(value = "USER_ID", type = IdType.ASSIGN_ID)private Long userId;private String nickName;private String headImage;private Integer sex;private String phone;private String code;private String email;private String wechat;private String schoolName;private String majorName;private String introduce;private Integer status;
}

配置文件bootstrap.yml

server:port: 9202
# Spring

nacos配置文件

除此之外我们还需要配置gateway的白名单以及路由

server:port: 19090

security:ignore:whites:- /system/sysUser/login- /friend/user/sendCode- /friend/user/code/login- /friend/user/test
jwt:secret: zxsksjdjoss

登录注册接口

登录流程设计

  • 点击登录按钮后，系统会执行以下验证和操作流程
  • 验证码校验阶段： 从Redis缓存中获取当前手机号对应的验证码，与用户输入的验证码进行比对。若验证失败则立即终止流程
  • 用户验证阶段： 通过手机号查询数据库用户表。若用户存在则识别为老用户，不存在则进入新用户注册流程
  • 老用户处理： 生成新的访问令牌（Token），将完整的用户信息存入Redis缓存，设置合理的过期时间
  • 新用户处理： 自动完成新用户注册，为手机号创建基础用户记录并保存到数据库。随后执行与老用户相同的令牌生成和缓存操作

 @Overridepublic String codeLogin(String phone, String code) {checkCode(phone, code);User user = userMapper.selectOne(new LambdaQueryWrapper<User>().eq(User::getPhone, phone));if (user == null) {  //新用户//注册逻辑user = new User();user.setPhone(phone);user.setStatus(UserStatus.Normal.getValue());user.setCreateBy(Contants.SYSTEM_USER_ID);userMapper.insert(user);}return tokenService.createToken(user.getUserId(), secret, UserIdentity.ORDINARY.getCode(), user.getNickName(), user.getHeadImage());}

其余方法

方法1： 验证码校对

方法2： 获得手机号::密码key

方法3：获得密码：：时间key

方法4：校验手机号格式是否正确

    private void checkCode(String phone, String code) {String phoneCodeKey = getPhoneCodeKey(phone);String cacheCode = redisService.getCacheObject(phoneCodeKey, String.class);if (StrUtil.isEmpty(cacheCode)) {throw new ServiceException(ResultCode.FAILED_INVALID_CODE);}if (!cacheCode.equals(code)) {throw new ServiceException(ResultCode.FAILED_ERROR_CODE);}//验证码比对成功redisService.deleteObject(phoneCodeKey);}private String getPhoneCodeKey(String phone) {return CacheConstants.PHONE_CODE_KEY + phone;}private String getCodeTimeKey(String phone) {return CacheConstants.CODE_TIME_KEY + phone;}public static boolean checkPhone(String phone) {Pattern regex = Pattern.compile("^1[2|3|4|5|6|7|8|9][0-9]\\d{8}$");Matcher m = regex.matcher(phone);return m.matches();}

退出登录

点击退出按钮时，系统会先检查token是否为空。若token存在且包含预设前缀，则先去除前缀，再执行token删除操作。具体流程为：解析token获取对应的redis键值，然后在redis中删除该键值。

  @DeleteMapping("/logout")public R<Void> logout(@RequestHeader(HttpConstants.AUTHENTICATION) String token) {return toR(userService.logout(token));}
 @Overridepublic boolean logout(String token) {if (StrUtil.isNotEmpty(token) && token.startsWith(HttpConstants.PREFIX)) {token = token.replaceFirst(HttpConstants.PREFIX, StrUtil.EMPTY);}return tokenService.deleteLoginUser(token, secret);}

获得信息

从请求头中提取token并解析后，若未能从Redis获取到对应的LoginUser信息，则返回错误响应；若成功获取，则将LoginUser中的相关数据映射到返回给前端的VO对象中。

  @GetMapping("/info")public R<LoginUserVO> info(@RequestHeader(HttpConstants.AUTHENTICATION) String token) {return userService.info(token);}
 @Overridepublic R<LoginUserVO> info(String token) {if (StrUtil.isNotEmpty(token) && token.startsWith(HttpConstants.PREFIX)) {token = token.replaceFirst(HttpConstants.PREFIX, StrUtil.EMPTY);}LoginUser loginUser = tokenService.getLoginUser(token, secret);System.out.println(loginUser);if (loginUser == null) {return R.fail();}LoginUserVO loginUserVO = new LoginUserVO();loginUserVO.setNickName(loginUser.getNickName());loginUserVO.setHeadImage(loginUser.getHeadImage());System.out.println(loginUserVO);return R.ok(loginUserVO);}

request.js

和之前学的一样，不做多余解释

import axios from 'axios'
import { getToken, removeToken } from './cookie'
import router from '@/router';//不同的功能，通过axios请求的是不同接口的地址
//127.0.0.1:19090
const service = axios.create({baseURL:"/dev-api",timeout:5000,

service.interceptors.request.use((config) => {if (getToken()) {config.headers["Authorization"] = "Bearer " + getToken();}return config;},(error) => {console.log(error)Promise.reject(error);}
);//响应拦截器
service.interceptors.response.use((res) => {  //res : 响应数据// 未设置状态码则默认成功状态const code = res.data.code;const msg = res.data.msg;if (code === 3001) {ElMessage.error(msg);removeToken()return Promise.reject(new Error(msg));} else if (code !== 1000) {ElMessage.error(msg);return Promise.reject(new Error(msg));} else {return Promise.resolve(res.data);}},(error) => {return Promise.reject(error);}
);export default service

cookie.js

和之前系统用户那里一样，不做多余解释

import Cookies from "js-cookie";
const TokenKey = "Oj-c-Token";export function getToken() {return Cookies.get(TokenKey);
}export function setToken(token) {return Cookies.set(TokenKey, token);
}export function removeToken() {return Cookies.remove(TokenKey);
}

index.js

路由功能，不做多余解释

import { createRouter, createWebHistory } from 'vue-router'const router = createRouter({history: createWebHistory(import.meta.env.BASE_URL),routes: [{path: "/",redirect: '/c-oj/home',},{path: "/c-oj/home",name: "home",component: () => import("@/views/Home.vue"),},{path: "/c-oj/login",name: "login",component: () => import("@/views/Login.vue"),},{path: "//c-oj/test",name: "test",component: () => import("@/views/Test.vue"),}],
})export default router

vite.config.js

配置功能，不多余解释

import { fileURLToPath, URL } from 'node:url'import { defineConfig } from 'vite'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
import vue from '@vitejs/plugin-vue'// https://vitejs.dev/config/
export default defineConfig({plugins: [vue(),AutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],resolve: {alias: {'@': fileURLToPath(new URL('./src', import.meta.url))}},server: {proxy: {"/dev-api": {target: "http://127.0.0.1:19090/friend",rewrite: (p) => p.replace(/^\/dev-api/, ""),},},},
})
