1.2 创建JavaBean

package com.czxy.zx.domain;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;

/**
 *
 */
@Data
@TableName("edu_user")
@ApiModel(value = "EduUser对象",description = "用户")
public class EduUser {

    @TableId(type = IdType.AUTO)
    private Integer id;
    //用户名
    private String username;
    //用户密码
    private String password;
    //电话
    private String phone;
    //邮箱
    private String email;
    //角色，多个值使用逗号分隔，例如：admin,editor
    private String roles;
    //创建时间
    private Date created;

}

1.3 用户服务环境

1.4 用户服务基本模块

拷贝配置类

编写mapper

package com.czxy.zx.user.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;

import com.czxy.zx.domain.EduUser;

import org.apache.ibatis.annotations.Mapper;

/**

* @author 桐叔

* @email liangtong@itcast.cn

@Mapper

public interface EduUserMapper extends BaseMapper<EduUser> {

}

编写service接口

package com.czxy.zx.user.service;

import com.baomidou.mybatisplus.extension.service.IService;

import com.czxy.zx.domain.EduUser;

/**

* @author 桐叔

* @email liangtong@itcast.cn

public interface EduUserService extends IService<EduUser> {

}

编写service实现类

package com.czxy.zx.user.service.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;

import com.czxy.zx.domain.EduUser;

import com.czxy.zx.user.mapper.EduUserMapper;

import com.czxy.zx.user.service.EduUserService;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

/**

@Service

@Transactional

public class EduUserServiceImpl extends ServiceImpl<EduUserMapper, EduUser> implements EduUserService {

}

编写controller

package com.czxy.zx.user.controller;

import com.czxy.zx.user.service.EduUserService;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**

* @author 桐叔

* @email liangtong@itcast.cn

@RestController

@RequestMapping("/user")

public class EduUserController {

@Resource

private EduUserService eduUserService;

}

2. MQ服务

创建项目： zx-mq31 编写pom文件

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-amqp</artifactId>

</dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-mail</artifactId>

</dependency>

<groupId>com.alibaba</groupId>

<artifactId>fastjson</artifactId>

</dependency>

<artifactId>zx-common31</artifactId>

default-encoding: UTF-8 #默认编码时

rabbitmq:

host: 127.0.0.1

port: 5672

username: guest

passowrd: guest

virtualHost: /

拷贝工具类

编写启动类 package com.czxy.zx;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

/**

* @author 桐叔

* @email liangtong@itcast.cn

@SpringBootApplication

public class MQApplication {

public static void main(String[] args) {

SpringApplication.run(MQApplication.class,args);

}

3. 用户登录

element ui admin 执行流程图

3.0 取消登录表单校验

3.1 发送验证码邮件

3.1.1 前端：显示表单

登录页面：@/views/login/index.vue

<!-- 邮箱 -->
      <el-form-item prop="email">
        <span class="svg-container">
          <svg-icon icon-class="email" />
        </span>
        <el-input
          ref="email"
          v-model="loginForm.email"
          placeholder="请输入邮箱"
          name="email"
          type="text"
          tabindex="3"
          style="width:70%;"
        />
        <el-button  type="primary" style="width:20%" @click.native.prevent="sendEmail">发送</el-button>
      </el-form-item>
      <!-- 验证码 -->
      <el-form-item prop="verifycode">
        <span class="svg-container">
          <svg-icon icon-class="guide" />
        </span>
        <el-input
          ref="verifycode"
          v-model="loginForm.verifycode"
          placeholder="请输入验证码"
          name="verifycode"
          type="text"
          tabindex="4"
        />
      </el-form-item>

3.1.2 前端：发送邮件

编写API，发送邮件

export function send(user) {
  return axios.post('/user-service/user/sendemail',user);
}

调用

    async sendEmail() {
      let { message } = await send( this.loginForm)
      this.$message.success( message )
    }

3.1.3 完善 EduUser

用于封装表单提交的用户数据

package com.czxy.zx.domain;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import lombok.Data;

import java.util.Date;

/**
 *
 */
@Data
//@TableName("edu_user")
@ApiModel(value = "EduUser对象",description = "用户")
public class EduUser {

    @TableId(value="id" , type = IdType.AUTO)
    private Integer id;
    //用户名
    private String username;
    //用户密码
    private String password;
    //电话
    private String phone;
    //邮箱
    private String email;
    //角色，多个值使用逗号分隔，例如：admin,editor
    private String roles;
    //创建时间
    private Date created;
    //状态：0 未激活、1已激活
    private String status;

    @TableField(exist = false)
    private String verifycode;

}

3.1.4 用于封装与MQ交互的数据

package com.czxy.zx.vo; import lombok.Data; /** * @author 桐叔 * @email liangtong@itcast.cn */ @Data public class UserEmail { private String username; private String email; private String text; }

3.1.5 编写Rabbit配置类

package com.czxy.zx.user.config;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

/**
 * @author 桐叔
 * @email liangtong@itcast.cn
 */
@Component
public class RabbitEmailConfig {
    // 队列的名称
    public static final String QUEUE_NAME = "zx-email";

    @Bean
    public Queue queue() {
        return new Queue(QUEUE_NAME);
    }
}

3.1.6 后端实现

/**
 * @author 桐叔
 * @email liangtong@itcast.cn
 */
@RestController
@RequestMapping("/user")
public class EduUserController {

    @Resource
    private EduUserService eduUserService;

    @Resource
    private StringRedisTemplate stringRedisTemplate;

    @Resource
    private RabbitTemplate rabbitTemplate;

    @PostMapping("/sendemail")
    public BaseResult sendemail(@RequestBody EduUser eduUser) {
        //1 随机字符串
        Random random = new Random();
        // [0,8999) --> [1000,9999)
        int randomNumber = random.nextInt(8999) + 1000;

        //2 发送redis一份
        stringRedisTemplate.opsForValue().set("login" + eduUser.getUsername(), randomNumber + "");

        //3 mq存放
        UserEmail userEmail = new UserEmail();
        userEmail.setUsername(eduUser.getUsername());
        userEmail.setEmail(eduUser.getEmail());
        userEmail.setText("登录验证码是：" + randomNumber);

        String userEmailStr = JSONObject.toJSONString(userEmail);
        rabbitTemplate.convertAndSend(RabbitEmailConfig.QUEUE_NAME , userEmailStr);

        return BaseResult.ok("发送中，请查收");
    }

3.2 编写MQ：发送邮件

3.2.1 拷贝配置类

与登录模块使用的配置类相同

package com.czxy.zx.config;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

/**
 * @author 桐叔
 * @email liangtong@itcast.cn
 */
@Component
public class RabbitEmailConfig {
    // 队列的名称
    public static final String QUEUE_NAME = "zx-email";

    @Bean
    public Queue queue() {
        return new Queue(QUEUE_NAME);
    }
}

3.2.2 监听器发送邮件

package com.czxy.zx.listener;

import com.alibaba.fastjson.JSONObject;
import com.czxy.zx.config.RabbitEmailConfig;
import com.czxy.zx.utils.EmailUtils;
import com.czxy.zx.vo.UserEmail;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * @author 桐叔
 * @email liangtong@itcast.cn
 */
@Component
public class RabbitEmailListener {
    @Resource
    private JavaMailSender javaMailSender;

    @RabbitListener(queues = RabbitEmailConfig.QUEUE_NAME)
    public void sendEmail(String message) {
        //1 将消息转换成 UserEmail
        UserEmail userEmail = JSONObject.parseObject(message, UserEmail.class);

        //2 发送邮件,如果邮箱为空，将出现循环异常
       if(userEmail.getEmail() != null) { EmailUtils.sendEmail(javaMailSender,userEmail.getEmail(),userEmail.getText());
       }

    }

}

3.3 后端：用户登录

3.3.0 前端登录流程

步骤一：登录页面 @/views/login/index.vue

步骤二：登录调用 vuex

步骤三：查看vuex

步骤四：调用ajax

步骤五：确定ajax发送位置

3.3.1 修改前端api

export function login(user) {
  // 真实数据
  return axios.post('/user-service/user/login',user);
  // 临时模拟
  // return axios.post('/teacher-service/user/login',user);
}

3.3.2 修改前端请求数据

3.3.2 后端实现

EduUserController 添加 login 方法

package com.czxy.zx.user.controller;

import com.alibaba.fastjson.JSON;
import com.czxy.zx.domain.EduUser;
import com.czxy.zx.user.config.RabbitEmailConfig;
import com.czxy.zx.user.service.EduUserService;
import com.czxy.zx.vo.BaseResult;
import com.czxy.zx.vo.UserEmail;
import org.apache.commons.lang3.RandomUtils;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
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;

import javax.annotation.Resource;

/**
 * @author 桐叔
 * @email liangtong@itcast.cn
 */
@RestController
@RequestMapping("/user")
public class EduUserController {

    @Resource
    private EduUserService eduUserService;

    @Resource
    private RabbitTemplate rabbitTemplate;

    @Resource
    private StringRedisTemplate stringRedisTemplate;

    @PostMapping("/send")
    public BaseResult send(@RequestBody EduUser eduUser) {
        //1 随机生成验证码
        int num = RandomUtils.nextInt(1000, 10000);
        //2 封装发送邮件的数据--
        UserEmail userEmail = new UserEmail();
        userEmail.setEmail(eduUser.getEmail());
        userEmail.setTitle("用户登录验证码");
        userEmail.setText(eduUser.getUsername() + "您好，本次验证码：" + num);

        //3 发送邮件-将邮件信息存放mq
        String jsonStr = JSON.toJSONString(userEmail);
        rabbitTemplate.convertAndSend("", RabbitEmailConfig.QUEUE_NAME, jsonStr);

        //4 将验证码存放redis
        String redisName = "login_verify_code_" + eduUser.getUsername();
        stringRedisTemplate.opsForValue().set(redisName, num + "");

        //5 提示
        return BaseResult.ok("验证码发送成功！");

    }

    @PostMapping("/login")
    public BaseResult login(@RequestBody EduUser eduUser) {
        //1 校验验证码
        // 1.1 获得redis
        String redisName = "login_verify_code_" + eduUser.getUsername();
        String redisVerifyCode = stringRedisTemplate.opsForValue().get(redisName);
        // 1.2 删除redis
        stringRedisTemplate.delete(redisName);
        // 1.3 校验：无效
        if(redisVerifyCode == null) {
            return BaseResult.error("验证码无效");
        }
        // 1.4 校验：错误
        if(!redisVerifyCode.equalsIgnoreCase(eduUser.getVerifycode())) {
            return BaseResult.error("验证码错误");
        }

        //2 通过service用户登录
        EduUser loginUser = eduUserService.login(eduUser);

        //3 提示
        if(loginUser != null) {
            // 需要设置token
            String token = "admin-token";
            return BaseResult.ok("登录成功").append("token", token);
        }
        return BaseResult.error("用户名或密码不匹配");
    }

}

3.3.4 前端修改

3.3.5 数据要求 admin-token

登录成功后，查询用户详情的使用

3.4 登录成功后查询权限

3.4.1 分析

登录时，返回一个固定的字符串：admin-token 或 editor-token
登录成功后，查询用户详情将携带固定字符串

根据固定字符串查询用户的权限，并返回固定的信息： { roles: ['admin'], //用户角色或 [editor] 或 [admin,editor] avatar: '', //头像图片地址 name: '', //用户名 }

查询详情ajax调用时机

3.4.2 前端完善

3.4.3 后端实现完善 EduUserController，添加查询详情功能

/**

* 查询详情

* @param token

* @return

@GetMapping("/info")

public BaseResult info(String token) {

System.out.println(token);

Map<String,Object> map = new HashMap<>();

// 根据固定字符串拼凑数据

if("admin-token".equals(token)) {

map.put("roles", Arrays.asList("admin"));

map.put("avatar","https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif");

map.put("name","Super Admin");

} else {

map.put("roles", Arrays.asList("editor"));

map.put("avatar","https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif");

map.put("name","Normal Editor");

}

return BaseResult.ok("成功", map);

}

        }

        return BaseResult.ok("注册失败");
    }

4.3 前端实现

4.3.1 显示页面

创建页面 @/views/edu/user/register.vue

<template>
  <div>
    注册
  </div>
</template>

<script>
export default {

}
</script>

<style>

</style>

编写路由

  {
    path: '/register',
    component: () => import('@/views/edu/user/register'),
    hidden: true			//登录成功后，左侧菜单中不显示
  }

修改登录页面

<el-button class="thirdparty-button" type="primary" style="right:80px;" @click="showDialog=true">
   三方登录
</el-button>
<el-button class="thirdparty-button" type="primary" @click="$router.push('/register')">
    注册
 </el-button>

将注册连接添加到白名单

4.3.2 前端 api

export function register(user) {
  // 真实数据
  return axios.post('/user-service/user/register',user);
}

4.3.3 注册页面

5 整合JWT

5.0 分析

5.1 搭建环境

5.1.1 拷贝坐标

        <!--JavaBean工具类，用于JavaBean数据封装-->
        <dependency>
            <groupId>commons-beanutils</groupId>
            <artifactId>commons-beanutils</artifactId>
        </dependency>
        <!--jwt工具-->
        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt</artifactId>
        </dependency>

        <!--joda 时间工具类 -->
        <dependency>
            <groupId>joda-time</groupId>
            <artifactId>joda-time</artifactId>
        </dependency>

5.1.2 复制yml配置

sc:
  jwt:
    secret: sc@Login(Auth}*^31)&czxy% # 登录校验的密钥
    pubKeyPath: D:/rsa/rsa.pub # 公钥地址
    priKeyPath: D:/rsa/rsa.pri # 私钥地址
    expire: 360 # 过期时间,单位分钟

5.1.3 拷贝配合类

拷贝：JwtProperties

package com.czxy.zx.user.config;

import com.czxy.zx.user.utils.RsaUtils;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;
import java.io.File;
import java.security.PrivateKey;
import java.security.PublicKey;

/**

 * @email liangtong@itcast.cn
 */
@Configuration
@ConfigurationProperties(prefix = "sc.jwt")
@Data
public class JwtProperties {
    private String secret;
    private String pubKeyPath;
    private String priKeyPath;
    private Integer expire;
    private PublicKey publicKey;
    private PrivateKey privateKey;

    @PostConstruct      //初始化方法注解
    public void init() {
        try {
            File pubFile = new File(pubKeyPath);
            File priFile = new File(priKeyPath);
            if(!pubFile.exists() || ! priFile.exists()) {
                RsaUtils.generateKey(pubKeyPath,priKeyPath,secret);
            }
            // 获得公钥和私钥对象
            this.publicKey = RsaUtils.getPublicKey(pubKeyPath);
            this.privateKey = RsaUtils.getPrivateKey(priKeyPath);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

5.1.4 拷贝工具类

拷贝工具类

5.1.5 生成秘钥（可选）

如果已经存在，此步省略

编写测试类，生成公钥和私钥 package com.czxy.zx.utils;

/**

* @author 桐叔

* @email liangtong@itcast.cn

public class TestRsa {

//公钥的位置

private static final String pubKeyPath = "D:\\rsa\\rsa.pub";

//私钥的位置

private static final String priKeyPath = "D:\\rsa\\rsa.pri";

public static void main(String[] args) throws Exception {

RsaUtils.generateKey(pubKeyPath,priKeyPath,"1234");

}

5.2 登录成功：生成token

准备工作已完成

登录成功，将 EduUser 转换成token，并响应给用户

 @PostMapping("/login")
    public BaseResult login(@RequestBody EduUser eduUser) {
        //1 校验验证码
        // 1.1 获得redis
        String redisName = "login_verify_code_" + eduUser.getUsername();
        String redisVerifyCode = stringRedisTemplate.opsForValue().get(redisName);
        // 1.2 删除redis
        stringRedisTemplate.delete(redisName);
        // 1.3 校验：无效
        if(redisVerifyCode == null) {
            return BaseResult.error("验证码无效");
        }
        // 1.4 校验：错误
        if(!redisVerifyCode.equalsIgnoreCase(eduUser.getVerifycode())) {
            return BaseResult.error("验证码错误");
        }

        //2 通过service用户登录
        EduUser loginUser = eduUserService.login(eduUser);

        //3 提示
        if(loginUser != null) {
            if("0".equals(loginUser.getStatus())) {
                return BaseResult.error("用户未激活，请先激活");
            }
            if("2".equals(loginUser.getStatus())) {
                return BaseResult.error("临时冻结，36小时");
            }
            if("3".equals(loginUser.getStatus())) {
                return BaseResult.error("该账号已冻结");
            }

            // 需要设置token
            //String token = "admin-token";
            String token = JwtUtils.generateToken(loginUser, jwtProperties.getExpire(), jwtProperties.getPrivateKey());
            return BaseResult.ok("登录成功").append("token", token);
        }
        return BaseResult.error("用户名或密码不匹配");
    }

5.3 查询详情：获得token

5.3.1 基本流程

登录成功后，默认跳转到 / 页面

访问 / ，在路由中配置跳转的位置

在跳转 / 页面前，执行vuex中 user/getInfo

通过vuex执行ajax请求，查询详情

5.3.2 查询详情

修改 EduUserController 添加方法

    @GetMapping("/info")
    public BaseResult info( String token) {
        try {
            //1 通过token 获得用户信息
            EduUser eduUser = JwtUtils.getObjectFromToken(token, jwtProperties.getPublicKey(), EduUser.class);

            //2 模拟数据
/*        Map<String,Object> map = new HashMap<>();
        if("admin-token".equalsIgnoreCase(token)) {
            map.put("roles", Arrays.asList("admin"));        //角色的值必须是数组
            map.put("avatar","https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif");
            map.put("name","张三三");
        } else {
            // 非管理员的权限
        }*/

            //3 真实数据
            Map<String,Object> map = new HashMap<>();
            if(eduUser.getRoles() != null) {
                map.put("roles", eduUser.getRoles().split(","));        //角色的值必须是数组
            } else {
                map.put("roles", Arrays.asList("editor"));        //没有权限的固定：editor
            }
            map.put("avatar","https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif");    //需要完善用户头像
            map.put("name",eduUser.getUsername());


            // 数据返回  baseResult.data --> Map
            return BaseResult.ok("获得权限成功", map);
        } catch (Exception e) {
            return BaseResult.error("获得权限失败");
        }
    }

6.作业：激活

6.1 分析

需求：
- 用户点击链接后可以进行账号激活，将用户的状态0改成1
- 用户重复点击，提示“账号已经激活，无需重复激活”
- 需要防止其他人帮着激活
- 激活成功了，跳转到登录页面，“账号已激活，请登录”
- 1天不激活，激活链接失效，需要重新发送

6.2 完善用户注册

@PostMapping("/register")
    public BaseResult register(@RequestBody EduUser eduUser) {
        //1 校验
        // 1.1 密码
        if(StringUtils.isBlank(eduUser.getPassword())) {
            ExceptionUtils.cast("密码不能为空");
        }
        if(! eduUser.getPassword().equals(eduUser.getRepassword())) {
            ExceptionUtils.cast("确认密码和密码不一致");
        }
        // 1.2 验证码
        // 1) 获得redis验证码
        String key = "register" + eduUser.getUsername() ;
        String redisVerifyCode = stringRedisTemplate.opsForValue().get(key);
        // 2） 删除redis验证码
        stringRedisTemplate.delete(key);
        // 3) 无效
        if(redisVerifyCode == null) {
            ExceptionUtils.cast("验证码无效");
        }
        // 4) 不对
        if(! redisVerifyCode.equalsIgnoreCase(eduUser.getVerifycode())) {
            ExceptionUtils.cast("验证码错误");
        }

        //2 注册
        boolean register = eduUserService.register(eduUser);

        //3 成功，发送激活邮件
        if(register) {
            // 成功
            // 获得uuid值
            String uuidStr = UUID.randomUUID().toString().replace("-", "");

            // 将uuid存放到redis中，设置有效时间
            stringRedisTemplate.opsForValue().set(uuidStr,eduUser.getUsername(), 24, TimeUnit.HOURS);

            // 发送激活邮件
            UserEmail userEmail = new UserEmail();
            userEmail.setEmail(eduUser.getEmail());
            userEmail.setTitle("XXX平台激活邮件");
            // TODO 作业：用户激活
            //String url = "http://localhost:10010/user-service/user/active?username=" + eduUser.getUsername();
            String url = "http://localhost:9527/#/active?uuid=" + uuidStr;
            String msg = eduUser.getUsername() + "，你好：<br/>" +
                        "<a href='"+url+"'>点击</a>链接进行账号激活。<br/>" +
                        "如果不能点击，请复制下面的连接：" + url;
            userEmail.setText(msg);
            System.out.println(eduUser.getId());

            //3 发送邮件-将邮件信息存放mq
            String jsonStr = JSON.toJSONString(userEmail);
            rabbitTemplate.convertAndSend("", RabbitEmailConfig.QUEUE_NAME, jsonStr);
            return BaseResult.ok("注册成功，请进行账号激活");
        }
        return BaseResult.error("注册失败");
    }

6.3 用户激活

6.3.1 前端实现

步骤：
- 步骤1：编写激活页面
- 步骤2：编写ajax函数
- 步骤3：添加白名单
步骤1：编写激活页面

<template>
  <div>用户激活页面</div>
</template>

<script>
import { active } from "@/api/user";
export default {
  methods: {
    async activeUserFn(uuid) {
      let baseResult = await active(uuid);
      this.$message.success(baseResult.message);
      this.$router.push('/login')
    }
  },
  mounted() {
    // 获得参数uuid
    let uuid = this.$route.query.uuid
    // 如果没有调整到登录页面
    if(! uuid) {
      this.$message.error('激活链接无效，请重新访问');
      this.$router.push('/login')
    } else {
      // 发送ajax进行激活
      this.activeUserFn(uuid);
    }
  },
}
</script>

<style>

</style>

步骤2：编写ajax函数

//激活
export function active(uuid) {
  return axios.get(`/user-service/user/active?uuid=${uuid}`)
}

步骤3：添加白名单

6.3.2 后端实现

 @GetMapping("/active")
    public BaseResult active(String uuid) {
        //1 使用uuid从redis获得信息
        String username = stringRedisTemplate.opsForValue().get(uuid);
        //2 判断，如果不存在给出提示
        if(username == null) {
            return BaseResult.ok("链接不完整or不需要激活or链接已超时");
        }
        //3 通过用户名查询用户
        QueryWrapper<EduUser> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("username", username);
        EduUser eduUser = eduUserService.getOne(queryWrapper);
        if(eduUser == null) {
            return BaseResult.ok("激活账号不存在");
        }
        //4 修改用户的状态 0 --> 1
        if(! "0".equals(eduUser.getStatus()) ) {
            return BaseResult.ok("账号不需要激活");
        }
        eduUser.setStatus("1");
        eduUserService.updateById(eduUser);
        //5 删除redis信息
        stringRedisTemplate.delete(uuid);
        //6 激活成功的提示
        return BaseResult.ok("激活成功");
    }

6.4 完善用户登录

@PostMapping("/login")
    public BaseResult login(@RequestBody EduUser eduUser) {
        //1 校验验证码
        // 1.1 获得redis
        String redisName = "login_verify_code_" + eduUser.getUsername();
        String redisVerifyCode = stringRedisTemplate.opsForValue().get(redisName);
        // 1.2 删除redis
        stringRedisTemplate.delete(redisName);
        // 1.3 校验：无效
        if(redisVerifyCode == null) {
            return BaseResult.error("验证码无效");
        }
        // 1.4 校验：错误
        if(!redisVerifyCode.equalsIgnoreCase(eduUser.getVerifycode())) {
            return BaseResult.error("验证码错误");
        }

        //2 通过service用户登录
        EduUser loginUser = eduUserService.login(eduUser);

        //3 提示
        if(loginUser != null) {
            if("0".equals(loginUser.getStatus())) {
                return BaseResult.error("用户未激活，请先激活");
            }
            if("2".equals(loginUser.getStatus())) {
                return BaseResult.error("临时冻结，36小时");
            }
            if("3".equals(loginUser.getStatus())) {
                return BaseResult.error("该账号已冻结");
            }

            // 需要设置token
            String token = "admin-token";
            return BaseResult.ok("登录成功").append("token", token);
        }
        return BaseResult.error("用户名或密码不匹配");
    }
