SpringBoot+Vue3项目邮箱验证码注册详细教程

标签：const SpringBoot 验证码 result Vue3 import data response

引言

该篇文章是以SpringBoot+Vue3技术栈搭建的项目的邮箱注册登录流程，注册用户使用邮箱校验，使用qq邮箱发送验证码，并且把验证码存入Redis以备校验使用的详细介绍

干货部分

1.在SpringBoot项目的application.yaml文件中配置qq邮箱

spring:
  # mail邮箱
  mail:
    # SMTP服务器（我用的是QQ邮箱的SMTP服务器地址，如果用的其它邮箱请另行百度搜索）
    host: smtp.qq.com
    # 发送验证码的邮箱（发件人的邮箱）
    username: ********@qq.com
    # 授权码  去qq邮箱的账户，开启服务，获取授权码
    password: ********
    # 编码
    default-encoding: utf-8
    # 其它参数
    properties:
      mail:
        smtp:
          # 如果是用SSL方式，需要配置如下属性,使用qq邮箱的话需要开启
          ssl:
            enable: true
            required: true
          # 邮件接收时间的限制，单位毫秒
          timeout: 10000
          # 连接时间的限制，单位毫秒
          connection-timeout: 10000
          # 邮件发送时间的限制，单位毫秒
          write-timeout: 10000

2.使用代码，后端代码

服务层代码，首先验证邮箱是否为空，然后在调用发送验证码业务之前，我们先从Redis通过该key获取数据，看看是否已经存在，如果已经存在，则证明已经发送过验证码并且还未使用。那么我们可以根据业务逻辑去做相应的处理，我这里是告诉前台，已经发送过了。然后调用EmailUtil工具类的生成验证码的方法，然后创建邮箱对象，填写对应参数信息。

package com.example.bootdemo.services.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.bootdemo.domain.entity.UserInfo;
import com.example.bootdemo.helper.EmailUtil;
import com.example.bootdemo.mapper.UserInfoMapper;
import com.example.bootdemo.services.IUserInfoService;
import jakarta.annotation.Resource;
import jakarta.mail.internet.InternetAddress;
import jakarta.mail.internet.MimeUtility;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;
import org.apache.commons.lang3.StringUtils;

import java.util.concurrent.TimeUnit;

@Service
public class UserInfoService extends ServiceImpl<UserInfoMapper, UserInfo> implements IUserInfoService {
    @Resource
    private StringRedisTemplate stringRedisTemplate;

    @Resource
    private JavaMailSender javaMailSender;

    @Resource
    private EmailUtil emailUtil;

    @Override
    public String sendEmail(String email) {
        if (StringUtils.isBlank(email)) {
            throw new RuntimeException("未填写收件人邮箱");
        }
        // 定义Redis的key
        String key = "msg_" + email;
        //操作字符串
        ValueOperations<String, String> valueOperations = stringRedisTemplate.opsForValue();
        String verifyCode = valueOperations.get(key);
        if (verifyCode == null) {
            // 随机生成一个6位数字型的字符串
            String code = emailUtil.generateVerifyCode(6);
            // 邮件对象（邮件模板，根据自身业务修改）
            SimpleMailMessage message = new SimpleMailMessage();
            message.setSubject("**用户注册邮箱验证码");
            message.setText("尊敬的用户您好!感谢您的注册。\n\n尊敬的: " + email + "您的校验验证码为: " + code + ",有效期5分钟，请不要把验证码信息泄露给其他人,如非本人请勿操作");
            message.setTo(email);

            try {
                // 对方看到的发送人（发件人的邮箱，根据实际业务进行修改，一般填写的是企业邮箱）
                message.setFrom(new InternetAddress(MimeUtility.encodeText("**ZWQ-INT") + "<**********@qq.com>").toString());
                // 发送邮件
                javaMailSender.send(message);
                // 将生成的验证码存入Redis数据库中，并设置过期时间
                valueOperations.set(key, code, 5L, TimeUnit.MINUTES);
                log.warn ("邮件发送成功");
                return "邮件发送成功";
            } catch (Exception e) {
                log.error("邮件发送出现异常");
                log.error("异常信息为" + e.getMessage());
                log.error("异常堆栈信息为-->");
                return "邮件发送失败";
            }
        } else {
            return "验证码已发送至您的邮箱，请注意查收";
        }
    }
}

工具类EmailUtil代码，封装了验证码校验，和生成随机验证码的功能。我们校验验证码的地方结合Redis的代码。校验成功，意味着我们已经使用了，就会去删除掉这个验证码的key。

package com.example.bootdemo.helper;

import jakarta.annotation.Resource;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;

import org.springframework.data.redis.core.StringRedisTemplate;
import java.util.Properties;
import java.util.Random;

/**
 * @ClassName EmailUtil
 * @Description 邮箱
 * @Author zhangweiqi
 * @Date 2024/9/12 下午4:09
 */
@Component
public class EmailUtil {


    @Resource
    private StringRedisTemplate stringRedisTemplate;

    /**
     * 随机生成指定长度字符串验证码
     *
     * @param length 验证码长度
     */
    public String generateVerifyCode(int length) {
        String strRange = "1234567890";
        StringBuilder strBuilder = new StringBuilder();

        for (int i = 0; i < length; ++i) {
            char ch = strRange.charAt((new Random()).nextInt(strRange.length()));
            strBuilder.append(ch);
        }
        return strBuilder.toString();
    }

    /**
     * 校验验证码（可用作帐号登录、注册、修改信息等业务）
     * 思路：先检查redis中是否有key位对应email的键值对，没有代表验证码过期；如果有就判断用户输入的验证码与value是否相同，进而判断验证码是否正确。
     */
    public Integer checkVerifyCode(String email, String code) {
        int result = 1;
        ValueOperations<String, String> valueOperations = stringRedisTemplate.opsForValue();
        String msgKey = "msg_" + email;
        String verifyCode = valueOperations.get(msgKey);
        /*校验验证码：0验证码错误、1验证码正确、2验证码过期*/
        if (verifyCode == null) {
            result = 2;
        } else if (!code.equals(verifyCode)) {
            result = 0;
        }
        // 如果验证码正确，则从redis删除
        if (result == 1) {
            stringRedisTemplate.delete(msgKey);
        }
        return result;
    }

}

注册用户，要先校验验证码，然后通过后才去注册用户

//注册用户
    @PostMapping("/registerUser")
    public Result<Boolean> registerUser(@RequestBody RegisterDTO entity){
        Result<Boolean> result = new Result<>();

        //验证码校验
        int res = emailUtil.checkVerifyCode(entity.getEmail(),entity.getCode());

        if(res == 0){
            result.setCode(StateCodeEnum.ERROR.getCode());
            result.setMsg("验证码错误！");
            result.setData(false);
            return result;
        }else if (res == 2){
            result.setCode(StateCodeEnum.ERROR.getCode());
            result.setMsg("验证码过期！");
            result.setData(false);
            return result;
        };

        //查询数据库是否已经存在
        //获取用户数据
        QueryWrapper<UserInfo> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("username", entity.getUsername()).eq("password", entity.getPassword());
        UserInfo userInfo = userInfoMapper.selectOne(queryWrapper);
        if(userInfo!=null){
            result.setCode(StateCodeEnum.ERROR.getCode());
            result.setMsg("用户已存在，注册失败！");
            result.setData(false);
            return result;
        }

        try {
            //插入用户表
            userInfoMapper.insert(BeanUtil.copyProperties(entity, UserInfo.class));
            result.setCode(StateCodeEnum.ERROR.getCode());
            result.setMsg("注册成功，请登录！");
            result.setData(true);
            return result;
        }catch (Exception e){
            result.setCode(StateCodeEnum.ERROR.getCode());
            result.setMsg(e.getMessage());
            return result;
        }
    }

效果

登陆页面

注册页面

邮箱验证码获取成功

我做了校验，重复用户信息，不准创建。

注册成功

登录成功

登陆成功，Redis的验证码清空

至此完成

总结

通过这篇文章，可以了解到，通过邮箱获取验证码，并把验证码存储到Redis里面，在注册时去Redis获取，和前端传过去的验证码做校验。来注册用户。此项目继承了JWT授权，如有想了解的，请前往Jwt授权，也是博主记录的。相对于之前的，前端接入了Element Plus UI，页面好看了不少。后端呢，封装了Result类去返回给前端。后续呢，前端会把调用接口封装一下，统一一下风格。后面这个初学项目代码会持续更新，慢慢完善。如有想要源码的，评论111。

有不对的地方欢迎指正，共同学习进步，祝您每天快乐✊。
