Shiro重构：整合token和cookie实现登陆及验证
认证服务开始只支持PC端的cookie认证方式，因业务需要，要对小程序、H5、App等移动端设备进行认证，这里复用认证服务。由于小程序不支持cookie认证方式，采用token认证方式，这里对认证服务进行重构。认证服务主要是有Shiro框架研发，我们简单熟悉下cookie的认证流程。
Shiro的cookie认证流程我们简单说明下，
- shiro是在其默认的会话管理器DefaultWebSessionManager中获取请求携带过来的cookie。主要的功能是添加、删除SessionId到cookie、读取cookie获得SessionId。
用户首先通过用户名口令或手机号+验证码方式，调用认证服务接口进行登陆操作。
Subject subject = SecurityUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken(username,password); subject.login(token);//当调用subject的登入方法时，会跳转到认证的方法上 User user = (User) subject.getPrincipal();//获取当前登陆对象 //TODO: 做之后的事情
这里用户登陆成功后，会将通过DefaultWebSessionManager，生成SessionId，并将sid做为key保存在redis缓存中（通过redis做session共享）。并将sid保存到cookie中，返回浏览器。
- 浏览器发起请求，传递cookie，Shiro框架通过DefaultWebSessionManager中的getSessionId方法，获取cookie中的Sid.
public Serializable getSessionId(SessionKey key) {
Serializable id = super.getSessionId(key);
if (id == null && WebUtils.isWeb(key)) {
ServletRequest request = WebUtils.getRequest(key);
ServletResponse response = WebUtils.getResponse(key);
id = this.getSessionId(request, response);
}
return id;
}
获取到sid后，到redis中查询用户信息，如果能获取到则通过，否则进行拦截处理。
一、重写DefaultWebSessionManager方法
用户请求到服务端后，首先判断该请求是否需要鉴权，如果不需要鉴权则直接放行。如果需要鉴权，则进入DefaultWebSessionManager中的getSessionId方法。这里我们重新定义个SessionManager，重写getSessionId方法。
我们定义个CustomerWebSessionManager继承DefaultWebSessionManager，重写getSessionId方法，我们首先从请求头中判断是否存在token,如果存在我们直接获取请求头中的token信息，并将token设置到请求头中request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, token)。
public class CustomerWebSessionManager extends DefaultWebSessionManager {
private static final String AUTH_TOKEN = "token";
private static final String DEVICE = "device";
private static final String MOBILE = "mobile";
public CustomerWebSessionManager() {
super();
}
@Override
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
if (!(request instanceof HttpServletRequest)) {
log.debug("Current request is not an HttpServletRequest - cannot get session ID. Returning null.");
return null;
}
HttpServletRequest httpRequest = WebUtils.toHttp(request);
if (StringUtils.hasText(httpRequest.getHeader(AUTH_TOKEN))) {
//从header中获取token
String token = httpRequest.getHeader(AUTH_TOKEN);
// 每次读取之后都把当前的token放入response中
HttpServletResponse httpResponse = WebUtils.toHttp(response);
if (StringUtils.hasText(token)) {
httpResponse.setHeader(AUTH_TOKEN, token);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, "header");
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, token);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
}
//sessionIdUrlRewritingEnabled的配置为false,不会在url的后面带上sessionID
request.setAttribute(ShiroHttpServletRequest.SESSION_ID_URL_REWRITING_ENABLED, isSessionIdUrlRewritingEnabled());
return token;
}
return getReferencedSessionId(request, response);
}
}
如果请求头中的token不存在，则走getReferencedSessionId方法，获取cookie中的信息。
private Serializable getReferencedSessionId(ServletRequest request, ServletResponse response) {
String id = getSessionIdcookievalue(request, response);
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
ShiroHttpServletRequest.cookie_SESSION_ID_SOURCE);
} else {
//not in a cookie, or cookie is disabled - try the request URI as a fallback (i.e. due to URL rewriting):
//try the URI path segment parameters first:
id = getUriPathSegmentParamValue(request, ShiroHttpSession.DEFAULT_SESSION_ID_NAME);
if (id == null) {
//not a URI path segment parameter, try the query parameters:
String name = getSessionIdName();
id = request.getParameter(name);
if (id == null) {
//try lowercase:
id = request.getParameter(name.toLowerCase());
}
}
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
ShiroHttpServletRequest.URL_SESSION_ID_SOURCE);
}
}
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
//automatically mark it valid here. If it is invalid, the
//onUnknownSession method below will be invoked and we'll remove the attribute at that time.
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
}
// always set rewrite flag - SHIRO-361
request.setAttribute(ShiroHttpServletRequest.SESSION_ID_URL_REWRITING_ENABLED, isSessionIdUrlRewritingEnabled());
return id;
}
这里验证请求头中的token方法重构完成。
@Override
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
if (!(request instanceof HttpServletRequest)) {
log.debug("Current request is not an HttpServletRequest - cannot get session ID. Returning null.");
return null;
}
HttpServletRequest httpRequest = WebUtils.toHttp(request);
if (StringUtils.hasText(httpRequest.getHeader(AUTH_TOKEN))) {
//从header中获取token
String token = httpRequest.getHeader(AUTH_TOKEN);
// 每次读取之后都把当前的token放入response中
HttpServletResponse httpResponse = WebUtils.toHttp(response);
if (StringUtils.hasText(token)) {
httpResponse.setHeader(AUTH_TOKEN, token);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, "header");
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, token);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
}
//sessionIdUrlRewritingEnabled的配置为false,不会在url的后面带上sessionID
request.setAttribute(ShiroHttpServletRequest.SESSION_ID_URL_REWRITING_ENABLED, isSessionIdUrlRewritingEnabled());
return token;
}
return getReferencedSessionId(request, response);
}
private Serializable getReferencedSessionId(ServletRequest request, ServletResponse response) {
String id = getSessionIdcookievalue(request, response);
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
ShiroHttpServletRequest.cookie_SESSION_ID_SOURCE);
} else {
//not in a cookie, or cookie is disabled - try the request URI as a fallback (i.e. due to URL rewriting):

}
}
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
ShiroHttpServletRequest.URL_SESSION_ID_SOURCE);
}
}
if (id != null) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
//automatically mark it valid here. If it is invalid, the
//onUnknownSession method below will be invoked and we'll remove the attribute at that time.
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
}
// always set rewrite flag - SHIRO-361
request.setAttribute(ShiroHttpServletRequest.SESSION_ID_URL_REWRITING_ENABLED, isSessionIdUrlRewritingEnabled());
return id;
}
private String getSessionIdcookievalue(ServletRequest request, ServletResponse response) {
if (!isSessionIdcookieEnabled()) {
log.debug("Session ID cookie is disabled - session id will not be acquired from a request cookie.");
return null;
}
if (!(request instanceof HttpServletRequest)) {
log.debug("Current request is not an HttpServletRequest - cannot get session ID cookie. Returning null.");
return null;
}
HttpServletRequest httpRequest = (HttpServletRequest) request;
return getSessionIdcookie().readValue(httpRequest, WebUtils.toHttp(response));
}
private String getUriPathSegmentParamValue(ServletRequest servletRequest, String paramName) {
if (!(servletRequest instanceof HttpServletRequest)) {
return null;
}
HttpServletRequest request = (HttpServletRequest) servletRequest;
String uri = request.getRequestURI();
if (uri == null) {
return null;
}
int queryStartIndex = uri.indexOf('?');
if (queryStartIndex >= 0) {
uri = uri.substring(0, queryStartIndex);
}
int index = uri.indexOf(';');
if (index < 0) {
//no path segment params - return:
return null;
}
//there are path segment params, let's get the last one that may exist:
final String TOKEN = paramName + "=";
uri = uri.substring(index + 1);
//we only care about the last JSESSIONID param:
index = uri.lastIndexOf(TOKEN);
if (index < 0) {
//no segment param:
return null;
}
uri = uri.substring(index + TOKEN.length());
index = uri.indexOf(';');
if (index >= 0) {
uri = uri.substring(0, index);
}
return uri;
}
private String getSessionIdName() {
String name = this.getSessionIdcookie() != null ? this.getSessionIdcookie().getName() : null;
if (name == null) {
name = ShiroHttpSession.DEFAULT_SESSION_ID_NAME;
}
return name;
}
二、登陆将token设置到响应头中
我们编写用户登陆接口，在用户登陆时，cookie方式是将sid直接写入到浏览器cookie中，这样前端人员无法获取token值。需要我们将token返回给前端。这里我们将token放到响应头中。
我们登陆时无cookie和token,当shiro取不到sessionid时,会调用DelegatingSubject类中的getSession(true)方法创建一个新的session.
public Session getSession(boolean create) {
if (log.isTraceEnabled()) {
log.trace("attempting to get session; create = " + create +
"; session is null = " + (this.session == null) +
"; session has id = " + (this.session != null && session.getId() != null));
}
if (this.session == null && create) {
//added in 1.2:
if (!isSessionCreationEnabled()) {
String msg = "Session creation has been disabled for the current subject. This exception indicates " +
"that there is either a programming error (using a session when it should never be " +
"used) or that Shiro's configuration needs to be adjusted to allow Sessions to be created " +
"for the current Subject. See the " + DisabledSessionException.class.getName() + " JavaDoc " +
"for more.";
throw new DisabledSessionException(msg);
}
log.trace("Starting session for host {}", getHost());
SessionContext sessionContext = createSessionContext();
Session session = this.securityManager.start(sessionContext);
this.session = decorate(session);
}
return this.session;
}
会调用Session session = this.securityManager.start(sessionContext);方法，最终调用的是DefaultWebSessionManager中的onStart方法。所以我们要重写这个方法,将产生的sessionid放到response header中.另外当session失效或销毁时的相关方法也需重新实现,具体代码如下：
这里我们在存储sid增加了判断逻辑，如请求头中包含设备信息，则将sid存在到响应头中，否则存在到cookie中。
private void storeSessionId(Serializable currentId, HttpServletRequest request, HttpServletResponse response) {
if (currentId == null) {
String msg = "sessionId cannot be null when persisting for subsequent requests.";
throw new IllegalArgumentException(msg);
}
String idString = currentId.toString();
//增加判断，如果请求头中包含DEVICE=MOBILE，则将sessionId放在header中返回
if (StringUtils.hasText(request.getHeader(DEVICE)) && MOBILE.equals(request.getHeader(DEVICE))) {
response.setHeader(AUTH_TOKEN, idString);
} else {
cookie template = getSessionIdcookie();
cookie cookie = new Simplecookie(template);
cookie.setValue(idString);
cookie.saveTo(request, response);
}
log.trace("Set session ID cookie for session with id {}", idString);
}
private void removeSessionIdcookie(HttpServletRequest request, HttpServletResponse response) {
if (StringUtils.hasText(request.getHeader(AUTH_TOKEN))) {
response.setHeader(AUTH_TOKEN, cookie.DELETeD_cookie_VALUE);
} else {
getSessionIdcookie().removeFrom(request, response);
}
}
@Override
protected void onStart(Session session, SessionContext context) {
super.onStart(session, context);
if (!WebUtils.isHttp(context)) {
log.debug("SessionContext argument is not HTTP compatible or does not have an HTTP request/response " +
"pair. No session ID cookie will be set.");
return;
}
HttpServletRequest request = WebUtils.getHttpRequest(context);
HttpServletResponse response = WebUtils.getHttpResponse(context);
if (isSessionIdcookieEnabled()) {
Serializable sessionId = session.getId();
storeSessionId(sessionId, request, response);
} else {
log.debug("Session ID cookie is disabled. No cookie has been set for new session with id {}", session.getId());
}
request.removeAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_IS_NEW, Boolean.TRUE);
}
@Override
protected void onExpiration(Session s, ExpiredSessionException ese, SessionKey key) {
super.onExpiration(s, ese, key);
onInvalidation(key);
}
@Override
protected void onInvalidation(Session session, InvalidSessionException ise, SessionKey key) {
super.onInvalidation(session, ise, key);
onInvalidation(key);
}
private void onInvalidation(SessionKey key) {
ServletRequest request = WebUtils.getRequest(key);
if (request != null) {
request.removeAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID);
}
if (WebUtils.isHttp(key)) {
log.debug("Referenced session was invalid. Removing session ID cookie.");
removeSessionIdcookie(WebUtils.getHttpRequest(key), WebUtils.getHttpResponse(key));
} else {
log.debug("SessionKey argument is not HTTP compatible or does not have an HTTP request/response " +
"pair. Session ID cookie will not be removed due to invalidated session.");
}
}
@Override
protected void onStop(Session session, SessionKey key) {
super.onStop(session, key);
if (WebUtils.isHttp(key)) {
HttpServletRequest request = WebUtils.getHttpRequest(key);
HttpServletResponse response = WebUtils.getHttpResponse(key);
log.debug("Session has been stopped (subject logout or explicit stop). Removing session ID cookie.");
removeSessionIdcookie(request, response);
} else {
log.debug("SessionKey argument is not HTTP compatible or does not have an HTTP request/response " +
"pair. Session ID cookie will not be removed due to stopped session.");
}
}
最后再在springboot中做如下配置:
@Bean("sessionManager")
public SessionManager sessionManager() {
DefaultWebSessionManager sessionManager = new CustomerWebSessionManager();
Collection listeners = new ArrayList();
//配置监听
listeners.add(sessionListener());
sessionManager.setSessionListeners(listeners);
cookie sessionIdcookie = sessionManager.getSessionIdcookie();
sessionIdcookie.setName("sid");
sessionManager.setGlobalSessionTimeout(EXPIRE_SECOND * 1000); // 超时时间
sessionManager.setDeleteInvalidSessions(true);
sessionManager.setSessionIdcookie(sessionIdcookie);
sessionManager.setSessionDAO(sessionDAO());
sessionManager.setCacheManager(cacheManager());
//全局会话超时时间（单位毫秒），默认30分钟 暂时设置为10秒钟 用来测试
sessionManager.setGlobalSessionTimeout(EXPIRE_SECOND * 1000);
//是否开启删除无效的session对象 默认为true
sessionManager.setDeleteInvalidSessions(true);
//是否开启定时调度器进行检测过期session 默认为true
sessionManager.setSessionValidationSchedulerEnabled(true);
//设置session失效的扫描时间, 清理用户直接关闭浏览器造成的孤立会话 默认为 1个小时
//设置该属性 就不需要设置 ExecutorServiceSessionValidationScheduler 底层也是默认自动调用ExecutorServiceSessionValidationScheduler
sessionManager.setSessionValidationInterval(600000);
//取消url 后面的 JSESSIonID
sessionManager.setSessionIdUrlRewritingEnabled(false);
return sessionManager;
}
我们使用PostMain测试下：
WX20211016-171120@2x
我们使用token测试下能否通过验证：
WX20211016-171425@2x
可以看到验证通过。使用错误的token验证下：
WX20211016-171530@2x
我们将token的最后一位2改成3后，验证失败。需要重新登陆。
自此我们改造完成。附上完整代码：
