本篇内容介绍了“怎么解决shiro会话超时302问题”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
产生异常的情况:nginx配置了https,但是nginx转发请求到web应用走的http,会话超时,shiro会重定向到登录页,这时重定向的是http地址,比如http://xxxxx/login/index ,浏览器会阻止这样的请求(从https页面发起http请求是非法的)。
重写shiro的FormAuthenticationFilter
public class MyShiroAuthcFilter extends FormAuthenticationFilter { public MyShiroAuthcFilter(String loginUrl) { super(); setLoginUrl(loginUrl); } @Override protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception { if (isLoginRequest(request, response)) { return super.onAccessDenied(request, response); } else { if (isAjax((HttpServletRequest) request)) { // 处理ajax请求 HttpServletResponse httpServletResponse = WebUtils.toHttp(response); httpServletResponse.addHeader("REQUIRE_AUTH", "true"); // ajax全局设置中有用 httpServletResponse.setStatus(HttpStatus.UNAUTHORIZED.value()); // 改变302状态码 } else { saveRequest(request); request.getRequestDispatcher(getLoginUrl()).forward(request, response); // 由于是nginx转发的,redirect 302会重定向到http协议,不是浏览器期望的https // saveRequestAndRedirectToLogin(request, response); } return false; } } private boolean isAjax(HttpServletRequest request) { String requestedWithHeader = request.getHeader("X-Requested-With"); return "XMLHttpRequest".equals(requestedWithHeader); } }
shiro的filter配置
@Bean public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) { String loginUrl = "/login/index"; ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean(); Map<String, Filter> filters = shiroFilter.getFilters(); filters.put("anon", new AnonymousFilter()); filters.put("authc", new MyShiroAuthcFilter(loginUrl)); Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>(); filterChainDefinitionMap.put("/supervisor/**", "authc"); filterChainDefinitionMap.put("/**", "anon"); shiroFilter.setSecurityManager(securityManager); shiroFilter.setLoginUrl(loginUrl); shiroFilter.setUnauthorizedUrl("/login/unauthorized"); shiroFilter.setFilters(filters); shiroFilter.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilter; }
ajax全局设置
$.ajaxSetup({ complete: function (xhr, status) { if (xhr.getResponseHeader('REQUIRE_AUTH') == 'true') { alert("未登录或登录超时!"); window.top.location.href = getHost() + '/login/index'; return; } } });
/login/index页面处理
<script type="text/javascript"> // 使登录页出现在“顶级”窗口,调整浏览器的url地址,上面的filter是forward到登录页的 if(window.top != window.self || location.pathname != '/login/index') { window.top.location = getHost() + '/login/index'; } </script>
