基于若依前后端分离框架的小程序的token验证

后端和管理端都用的若依框架。
但是前段的小程序需要微信授权登录。这时候就需要在若依框架上重新再起一套token验证。

首先创建两个类（只要放在你能够引用得到的位置就可以）：

第一个：实体

package com.ruoyi.system.toeknUnits;public class WxLoginUser{    private static final long serialVersionUID = 1L;        private Long userId;        private Long deptId;        private String token;        private Long loginTime;        private Long expireTime;        private String ipaddr;        private String loginLocation;        private String browser;        private String os;    private String openId;    private String nickName;// getset我不粘贴了， 也可以使用lombok的@Data}

第二个service：

package com.ruoyi.system.toeknUnits;import com.ruoyi.common.constant.Constants;import com.ruoyi.common.core.redis.RedisCache;import com.ruoyi.common.utils.ServletUtils;import com.ruoyi.common.utils.StringUtils;import com.ruoyi.common.utils.ip.AddressUtils;import com.ruoyi.common.utils.ip.IpUtils;import com.ruoyi.common.utils.uuid.IdUtils;import eu.bitwalker.useragentutils.UserAgent;import io.jsonwebtoken.*;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Component;import javax.servlet.http.HttpServletRequest;import java.util.HashMap;import java.util.Map;import java.util.concurrent.TimeUnit;@Componentpublic class WxTokenService{    // 令牌自定义标识    @Value("${token.header}")    private String header;    // 令牌秘钥    private String secret = "这个自己随便定义一段英文";    // 令牌有效期（默认30分钟）    @Value("${token.expireTime}")    private int expireTime;    protected static final long MILLIS_SECOND = 1000;    protected static final long MILLIS_MINUTE = 60 * MILLIS_SECOND;    private static final Long MILLIS_MINUTE_TEN = 20 * 60 * 1000L;    private static  final String wx_prefix = "tf";    @Autowired    private RedisCache redisCache;        public WxLoginUser getWxUser(HttpServletRequest request)    {        // 获取请求携带的令牌        String token = getToken(request);        if (StringUtils.isNotEmpty(token))        {            try            {                // 解析对应的权限以及用户信息                String userKey = token;                WxLoginUser user = redisCache.getCacheObject(userKey);                return user;            }            catch (Exception e)            {                e.printStackTrace();            }        }        return null;    }        public void setWxLoginUser(WxLoginUser wxUser)    {        if (StringUtils.isNotNull(wxUser) && StringUtils.isNotEmpty(wxUser.getToken()))        {            refreshToken(wxUser);        }    }        public void delWxUser(String token)    {        if (StringUtils.isNotEmpty(token))        {            String userKey = getTokenKey(token);            redisCache.deleteObject(userKey);        }    }        public String createToken(WxLoginUser wxUser)    {        String token = IdUtils.fastUUID();        wxUser.setToken(token);        setUserAgent(wxUser);        refreshToken(wxUser);        Map<String, Object> claims = new HashMap<>();        claims.put(wx_prefix, token);        return createToken(claims);    }        public void verifyToken(WxLoginUser wxUser)    {        long expireTime = wxUser.getExpireTime();        long currentTime = System.currentTimeMillis();        if (expireTime - currentTime <= MILLIS_MINUTE_TEN)        {            refreshToken(wxUser);        }    }        public void refreshToken(WxLoginUser wxUser)    {        wxUser.setLoginTime(System.currentTimeMillis());        wxUser.setExpireTime(wxUser.getLoginTime() + expireTime * MILLIS_MINUTE);        // 根据uuid将loginUser缓存        String userKey = getTokenKey(wxUser.getToken());        redisCache.setCacheObject(userKey, wxUser, expireTime, TimeUnit.MINUTES);    }        public void setUserAgent(WxLoginUser wxUser)    {        UserAgent userAgent = UserAgent.parseUserAgentString(ServletUtils.getRequest().getHeader("User-Agent"));        String ip = IpUtils.getIpAddr();        wxUser.setIpaddr(ip);        wxUser.setLoginLocation(AddressUtils.getRealAddressByIP(ip));        wxUser.setBrowser(userAgent.getBrowser().getName());        wxUser.setOs(userAgent.getOperatingSystem().getName());    }        private String createToken(Map<String, Object> claims)    {        String token = Jwts.builder()                .setClaims(claims)                .signWith(SignatureAlgorithm.HS512, secret).compact();        return token;    }        private Claims parseToken(String token)    {        JwtParser parser = Jwts.parser();        JwtParser jwtParser = parser.setSigningKey(secret);        Jws<Claims> claimsJws = jwtParser.parseClaimsJws(token);        Claims body = claimsJws.getBody();        System.out.println(body);        return Jwts.parser()                .setSigningKey(secret)                .parseClaimsJws(token)                .getBody();    }        public String getUsernameFromToken(String token)    {        Claims claims = parseToken(token);        return claims.getSubject();    }        public String getToken(HttpServletRequest request)    {        String token = request.getHeader(header);        if (StringUtils.isNotEmpty(token) && token.startsWith(wx_prefix))        {            token = token.replace(Constants.TOKEN_PREFIX, "");            return token;        }else{            return null;        }    }    private String getTokenKey(String uuid)    {        return "tf: " + uuid;    }}

下一步： 找到

com.ruoyi.framework.security.filter;

这个文件

package com.ruoyi.framework.security.filter;import java.io.IOException;import javax.servlet.FilterChain;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.ruoyi.system.toeknUnits.WxLoginUser;import com.ruoyi.system.toeknUnits.WxTokenService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;import org.springframework.security.core.context.SecurityContextHolder;import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;import org.springframework.stereotype.Component;import org.springframework.web.filter.OncePerRequestFilter;import com.ruoyi.common.core.domain.model.LoginUser;import com.ruoyi.common.utils.SecurityUtils;import com.ruoyi.common.utils.StringUtils;import com.ruoyi.framework.web.service.TokenService;@Componentpublic class JwtAuthenticationTokenFilter extends OncePerRequestFilter{    @Autowired    private TokenService tokenService;    @Autowired    private WxTokenService wxTokenService;    @Override    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)            throws ServletException, IOException    {        if( wxTokenService.getToken(request) == null){            System.out.println("管理员用户");            LoginUser loginUser = tokenService.getLoginUser(request);            if (StringUtils.isNotNull(loginUser) && StringUtils.isNull(SecurityUtils.getAuthentication()))            {                tokenService.verifyToken(loginUser);                UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(loginUser, null, loginUser.getAuthorities());                authenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));                SecurityContextHolder.getContext().setAuthentication(authenticationToken);            }        }else{//            小程序逻辑            System.out.println("微信用户");            WxLoginUser wxUser = wxTokenService.getWxUser(request);            if (StringUtils.isNotNull(wxUser) && StringUtils.isNull(SecurityUtils.getAuthentication()))            {                wxTokenService.verifyToken(wxUser);                UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(wxUser, null, null);                authenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));                SecurityContextHolder.getContext().setAuthentication(authenticationToken);            }        }        chain.doFilter(request, response);    }}

添加你获取code之类的。就是添加白名单。
