『博客开发日记-后台』之绑定或更换邮箱接口的实现

绑定或更换邮箱接口的实现

---

绑定或更换邮箱接口的需求

需求和上面的手机号差不多 都一样的 就换个参

需要注意的是复制粘贴过来一些验证和参数一定要注意

---

代码实现

在 AdminUserController 中

@PutMapping("/email")
@SystemLog(businessName = "绑定或更换邮箱接口")
@ApiOperation(value = "绑定或更换邮箱接口", notes = "个人中心绑定或更换邮箱", response = String.class)
public ResponseResult updateOrBindEmail(@Valid @RequestBody UpdateOrBindEmailDto updateOrBindEmailDto)
{
    return adminUserService.updateOrBindEmail(updateOrBindEmailDto);
}

---

创建 UpdateOrBindEmailDto

/**
 * 绑定或更换邮箱请求DTO
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
@ApiModel(description = "绑定或更换邮箱请求对象")
public class UpdateOrBindEmailDto
{
    @NotBlank(message = "邮箱不能为空")
    @Pattern(regexp = "^[A-Za-z0-9+_.-]+@[A-Za-z0-9.-]+$", message = "邮箱格式不正确")
    @ApiModelProperty(value = "邮箱", required = true, example = "2962933152@qq.com")
    private String email;

    @NotBlank(message = "验证码不能为空")
    @Pattern(regexp = "^\\d{6}$", message = "验证码必须为6位数字")
    @ApiModelProperty(value = "验证码", required = true, example = "123555")
    private String code;

    @NotBlank(message = "密码不能为空")
    @ApiModelProperty(value = "当前密码", required = true, example = "password123456")
    private String password;
}

在 AdminUserServiceImpl 中

 //绑定或更换邮箱
@Override
@Transactional(rollbackFor = Exception.class)
public ResponseResult updateOrBindEmail(UpdateOrBindEmailDto updateOrBindEmailDto)
{
    //检测用户是否登录
    Long currentUserId = SecurityUtils.getUserId();
    if (currentUserId == null) {
        return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);
    }

    //校验邮箱格式
    String email = updateOrBindEmailDto.getEmail() == null ? null : updateOrBindEmailDto.getEmail().trim();
    if (!StringUtils.hasText(email)) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "邮箱不能为空");
    }
    if (!email.matches("^[A-Za-z0-9+_.-]+@[A-Za-z0-9.-]+$")) {
        return ResponseResult.errorResult(AppHttpCodeEnum.PHONE_FORMAT_ERROR);
    }

    //验证码不能为空
    String code = updateOrBindEmailDto.getCode() == null ? null : updateOrBindEmailDto.getCode().trim();
    if (!StringUtils.hasText(code)) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "验证码不能为空");
    }

    //密码不能为空
    String password = updateOrBindEmailDto.getPassword() == null ? null : updateOrBindEmailDto.getPassword().trim();
    if (!StringUtils.hasText(password)) {
        return ResponseResult.errorResult(AppHttpCodeEnum.PASSWORD_NOT_NULL, "密码不能为空");
    }

    //验证当前用户是否存在
    SysUser currentUser = adminUserService.getById(currentUserId);
    if (currentUser == null) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "用户不存在");
    }

    //校验验证码
    String redisKey = String.format("admin:code:%s", email);
    String cacheCode = redisCache.getCacheObject(redisKey);
    if (!StringUtils.hasText(cacheCode)) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "验证码已过期，请重新获取");
    }
    if (!Objects.equals(cacheCode, code)) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "验证码错误");
    }

    //校验当前密码
    if (!passwordEncoder.matches(password, currentUser.getPassword())) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "密码错误");
    }

    //邮箱不能被其他用户占用
    LambdaQueryWrapper<SysUser> emailWrapper = new LambdaQueryWrapper<>();
    emailWrapper.eq(SysUser::getEmail, email)
            .ne(SysUser::getId, currentUserId);
    SysUser existUser = adminUserService.getOne(emailWrapper);
    if (existUser != null) {
        return ResponseResult.errorResult(AppHttpCodeEnum.PHONENUMBER_EXIST, "该邮箱已被其他用户绑定");
    }

    //更新邮箱
    LambdaUpdateWrapper<SysUser> updateWrapper = new LambdaUpdateWrapper<>();
    updateWrapper.eq(SysUser::getId, currentUserId)
            .set(SysUser::getEmail, email);
    boolean update = adminUserService.update(updateWrapper);
    if (!update) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "绑定邮箱失败");
    }

    //删除验证码缓存
    redisCache.deleteObject(redisKey);
    redisCache.deleteObject(String.format("admin:send:time:%s", email));

    return ResponseResult.okResult();
}
