Liferay嵌套方式集成三方应用

Liferay系统中添加三方应用的菜单

1. Liferay新建一个嵌入式页面
2. 填写URL内容，注意URL的域名一定要与liferay应用同域或子域，否则cookie无法获取到

   http://www.yicj1.com:9090/hello-web/index.jsp
   

3. 选择高级选项卡，填写JavaScript内容

   function getCookie(c_name){
   if (document.cookie.length>0){
       c_start=document.cookie.indexOf(c_name + "=") ;
       if (c_start!=-1){ 
           c_start=c_start + c_name.length+1 ;
           c_end=document.cookie.indexOf(";",c_start) ;
           if (c_end==-1){
             c_end=document.cookie.length ;
           } 
           return unescape(document.cookie.substring(c_start,c_end)) ;
       } 
     }
     return ""
   }
   var token = getCookie('token') ;
   var testsrc = document.getElementById('embeddedIframe');
   testsrc.src = testsrc.src+'?token='+token;
   

LoginPortlet将token写入cookies

1. 在登录完成后将token写入cookies

   /**
   * 登录完成后向浏览器写入token
   * 如果在此方法中添加cookies，必须在doview中同步清除
   * @author cx
   * @throws UnsupportedEncodingException 
   */
   private void addCookies(String token, HttpServletResponse response) 
       throws UnsupportedEncodingException {
   	String userToken = URLEncoder.encode(token, "utf-8");
   	response.addHeader("Set-Cookie", 
   	    "usertokenUrl=" + userToken + "; Path=/; Domain=yicj1.com");
   }
   

三方应用添加Filter根据token登录

1. 添加根据token登录的Filter

   public class TokenLoginFilter extends OncePerRequestFilter {
   	private Logger log = LoggerFactory.getLogger(TokenLoginFilter.class) ;
   	@Override
   	protected void doFilterInternal(HttpServletRequest request, 
   		HttpServletResponse response, FilterChain filterChain)
   			throws ServletException, IOException {
   		//log.info("========> TokenLoginFilter exec ");
   		String url = request.getRequestURL().toString() ;
   		log.info("request url : {}", url);
   		// 如果用户未登录则根据token登录
   		String token = request.getParameter("token") ;
   		HttpSession session = request.getSession() ;
   		log.info("session id : {}, request token : {}", session.getId(), token);
   		if (!StringUtils.isEmpty(token)) {
   			// 根据token解析出用户信息,并保存到session
   			log.info("用户信息保存到session中...");
   			User user = new User() ;
   			user.setUsername(token);
   			request.getSession().setAttribute("user", user);
   		}
   		// 执行下一个过滤器
   		filterChain.doFilter(request, response);
   	}
   }
   

2. 添加认证Filter（如三方应用存在则不需要重复添加）

   public class AuthenticationFilter extends OncePerRequestFilter {
   	private Logger log = LoggerFactory.getLogger(AuthenticationFilter.class) ;
   	@Override
   	protected void doFilterInternal(HttpServletRequest request, 
   	    HttpServletResponse response, FilterChain filterChain)
   			throws ServletException, IOException {
   		//log.info("====> AuthenticationFilter exec () ");
   		String url = request.getRequestURL().toString() ;
   		log.info("request url : {}", url);
   		String contextpath = request.getContextPath() ;
   		HttpSession session = request.getSession() ;
   		User user = (User)session.getAttribute("user") ;
   		log.info(session.getId() + " <==> log user info : {}", user);
   		// 如果用户未登录则跳转到登录页面
   		if (!isLoginOper(request) && user == null) {
   			response.sendRedirect(contextpath + "/login.jsp");
   		}else {
   			filterChain.doFilter(request, response);
   		}
   	}
   	/**
   	 * 判断是否为登录操作
   	 * @param request
   	 * @return
   	 */
   	private boolean isLoginOper(HttpServletRequest request) {
   		String uri = request.getRequestURI() ;
   		String contextpath = request.getContextPath() ;
   		//log.info("uri : {}", uri);
   		//log.info("contextpath : {}", contextpath);
   		return uri.startsWith(contextpath +"/login.jsp") 
   		       || uri.contentEquals(contextpath + "/login");
   	}
   }
   

注意事项

1. Liferay中配置的三方应用的URL一定要与Liferay应用同域或则为子域。（可通过nginx反向代理三方应用的域名）
2. 经测试发现不同域时，三方应用内部任意一次请求sessionId都会变化（三方应用内部后台请求或超链接）。
