CAS实现中文的属性
casServiceValidationSuccess.jsp页面默认编码格式为ISO-8859-1,且在表单提交到客户端页面时,也使用IS0进行编码,为了处理中文,可以在页面上使用URLEncoder对需要传递的中文时行UTF-8编码,然后从客户端取得数据时,再做URLDecoder解码:
casServiceValidationSuccess.jsp页面,真是一个奇怪的页面,由于cas使用手工解析(没有使用任何dom解析,硬编码识别标标签的开始和标签的结束)xml的方式解析xml文件,所有,在修改此文件时,一定要加以注意:
以下是源代码:
<%@ page session="false" contentType="text/xml; charset=UTF-8" import="java.net.URLEncoder"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
<cas:authenticationSuccess>
<cas:user>${fn:escapeXml(assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].principal.id)}</cas:user>
<c:if test="${not empty pgtIou}">
<cas:proxyGrantingTicket>${pgtIou}</cas:proxyGrantingTicket>
</c:if>
<c:if test="${fn:length(assertion.chainedAuthentications) > 1}">
<cas:proxies>
<c:forEach var="proxy" items="${assertion.chainedAuthentications}"
varStatus="loopStatus" begin="0"
end="${fn:length(assertion.chainedAuthentications)-2}"step="1">
<cas:proxy>${fn:escapeXml(proxy.principal.id)}</cas:proxy>
</c:forEach>
</cas:proxies>
</c:if>
<cas:attributes>
<c:forEach items="${assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].principal.attributes}"var="attr">
<c:set var="val" value="${attr.value}"/>
<cas:${attr.key}><%=URLEncoder.encode((String)pageContext.getAttribute("val"),"UTF-8")%></cas:${attr.key}>
</c:forEach>
</cas:attributes>
</cas:authenticationSuccess>
</cas:serviceResponse> 经过编码以后的XML数据如下: <cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'> <cas:authenticationSuccess> <cas:user>U003</cas:user> <cas:attributes> <cas:pwd>1111</cas:pwd> <cas:username>%E5%BC%A0%E4%B8%89</cas:username> </cas:attributes> </cas:authenticationSuccess> </cas:serviceResponse> 可见,对中文进行了UTF-8编码。 在客户端使用URLDecoder进行解码: 以下: <% Assertion assertion = AssertionHolder.getAssertion(); AttributePrincipal ap = assertion.getPrincipal(); String id = ap.getName(); Map<String,Object> att = ap.getAttributes(); out.print("<br/>"+id); out.print("<br/>"+att); String name = URLDecoder.decode(""+att.get("username"), "UTF-8"); out.println("<br/>"+name); %>
