基于若依框架的微信小程序登录

一、用户表结构

CREATE TABLE `bus_user` (
  `user_id` varchar(32) COLLATE utf8mb4_bin NOT NULL COMMENT '用户id',

  PRIMARY KEY (`user_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin ROW_FORMAT=DYNAMIC COMMENT='用户信息表';

三、登录时用到的SQL语句

①登录前查询用户信息是否存在
<select id="selectUserByPhone" resultMap="BusUserResult" parameterType="String">
        SELECT *
        FROM bus_user
        where phone_number = #{phoneNumber}
    </select>
  ②用户信息不存在时，新增用户
  <insert id="insertBusUser" parameterType="com.ldly.common.core.domain.entity.BusUser">
        insert into bus_user
        <trim prefix="(" suffix=")" suffixOverrides=",">

        </trim>
    </insert>
   ③用户信息存在且登录时，更新用户信息
   <update id="updateBusUser" parameterType="com.ldly.common.core.domain.entity.BusUser">
        update bus_user
        <trim prefix="SET" suffixOverrides=",">

四、微信用户登录验证

            throw new ServiceException("登录用户：" + mobile + " 不存在");
        }else if (UserStatus.DELETED.getCode().equals(busUser.getDelFlag())){
            log.info("登录用户：{} 已被删除.", mobile);
            throw new ServiceException("对不起，您的账号：" + mobile + " 已被删除");
        }else if (UserStatus.DISABLE.getCode().equals(busUser.getStatus())){
            log.info("登录用户：{} 已被停用.", mobile);
            throw new ServiceException("对不起，您的账号：" + mobile + " 已停用");
        }
        return new LoginUser(busUser);
    }

 public LoginUser(BusUser busUser) {
        SysUser sysUser = new SysUser();
        BeanUtils.copyBeanProp(sysUser,busUser);
        this.busUser = busUser;
        this.user = sysUser;
    }
 public BusUser selectUserByPhone(String phoneNumber) {
        return busUserMapper.selectUserByPhone(phoneNumber);
    }

五、创建token令牌

public String createToken(LoginUser loginUser)
    {
        String token = IdUtils.fastUUID();
        loginUser.setToken(token);
        setUserAgent(loginUser);
        refreshToken(loginUser);

        Map<String, Object> claims = new HashMap<>();
        claims.put(Constants.LOGIN_USER_KEY, token);
        return createToken(claims);
    }

  /**
     * 令牌前缀    类名：Constants
     */
    public static final String LOGIN_USER_KEY = "login_user_key";

/**
     * 从数据声明生成令牌
     *
     * @param claims 数据声明
     * @return 令牌
     */
    private String createToken(Map<String, Object> claims)
    {
        String token = Jwts.builder()
                .setClaims(claims)
                .signWith(SignatureAlgorithm.HS512, secret).compact();
        return token;
    }

/**
     * 刷新令牌有效期
     *
     * @param loginUser 登录信息
     */
    public void refreshToken(LoginUser loginUser)
    {
        loginUser.setLoginTime(System.currentTimeMillis());
        loginUser.setExpireTime(loginUser.getLoginTime() + expireTime * MILLIS_MINUTE);
        // 根据uuid将loginUser缓存
        String userKey = getTokenKey(loginUser.getToken());
        redisCache.setCacheObject(userKey, loginUser, expireTime, TimeUnit.MINUTES);
    }

    /**
     * 设置用户代理信息
     *
     * @param loginUser 登录信息
     */
    public void setUserAgent(LoginUser loginUser)
    {
        UserAgent userAgent = UserAgent.parseUserAgentString(ServletUtils.getRequest().getHeader("User-Agent"));
        String ip = IpUtils.getIpAddr();
        loginUser.setIpaddr(ip);
        loginUser.setLoginLocation(AddressUtils.getRealAddressByIP(ip));
        loginUser.setBrowser(userAgent.getBrowser().getName());
        loginUser.setOs(userAgent.getOperatingSystem().getName());
    }
  private String getTokenKey(String uuid)
    {
        return CacheConstants.LOGIN_TOKEN_KEY + uuid;
    }
