CAS 经验收集

１，非常遗憾，经过查证，SSL协议只支持domain name，也就是你可以用你的计算机名或者localhost，我用domain name做过测试，完全正确。

假如我的电脑ip为192.168.6.110，我的电脑名为netfly
那么，在生成证书的时候，就不能输入localhost，只能输入netfly，在其他电脑上，一样可以通过ip访问我的服务。比如说，输入
http://192.168.6.110:8080/YaleCASTest/hello.jsp
http://192.168.6.110:8080/YaleCASTest/servlet/RequestInfo

都可以返回正确的信息，不过，web.xml也要改改，如下：

 

代码

2.     <filter-name>CASFilter</filter-name>

10.         <param-value>https://netfly:8443/cas/proxyValidate</param-value>  
11.     </init-param><!--这里的serName是服务端的主机名，而且必须是-->  
12.     <init-param>  
13.       <param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>  
14.       <param-value>netfly:8080</param-value><!--client:port就是需要CAS需要拦截的地址和端口，一般就是这个TOMCAT所启动的IP和port-->  
15.     </init-param>  
16. </filter>  

 ２，CAS异常问题总结

严重: edu.yale.its.tp.cas.client.CASAuthenticationException: Unable to validate ProxyTicketValidator [[edu.yale.its.tp.cas.client.ProxyTicketValidator prox
yList=[null] [edu.yale.its.tp.cas.client.ServiceTicketValidator casValidateUrl=[https://192.168.1.111:8443/cas/proxyValidate] ticket=[ST-0-9h7Mx5HK3pfsdxRv
MD3y] service=[http%3A%2F%2F192.168.1.222%3A8080%2Fservlets-examples%2Fservlet%2FHelloWorldExample] renew=false]]]


这个CAS异常是从CAS Client里面抛出，是当我们不使用证书的CN去访问域名的时候（比如下文是用IP访问而且证书的CN是该IP对应的域名而非该IP），CASClient无法信任，因为你证书的CN命名写着abc.com，192.168.1.111这个IP是无法被CAS Client识别。

解决办法：
用域名访问，域名就是证书的CN。
