小试tomcat基本安全认证
背景:tomcat-5.5.12设置为远程服务器 服务端设置: Step 1) 打开${tomcat_home}/conf/tomcat-users.xml加入如下代码:<role rolename="test"/><user username="a" password="b" roles="test"/>
Step2)修改web.xml<security-constraint>
<display-name>Example Security Constraint</display-name>
<web-resource-collection>
<web-resource-name>Protected Area</web-resource-name>
<!-- Define the context-relative URL(s) to be protected -->
<url-pattern>/test/*</url-pattern>
<!-- If you list http methods, only those methods are protected -->
<http-method>DELETE</http-method>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
</web-resource-collection>
<auth-constraint>
<!-- Anyone with one of the listed roles may access this area -->
<role-name>test</role-name>
</auth-constraint>
</security-constraint>
<!-- Default login configuration uses BASIC authentication -->
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>WebService Form-Based Authentication Area</realm-name>
</login-config> 对网站/test/下的任何请求采用基本安全认证 客户端编程:客户端通过httpclient-2.0.2请求该url,方法如下: HttpClient httpClient = new HttpClient();
Credentials defaultcreds = new UsernamePasswordCredentials("a", "b");
httpClient.getState().setCredentials("WebService Form-Based Authentication Area","www.cat.cn",defaultcreds);
String url = "http://www.cat.cn/test/index.do";
GetMethod method = new GetMethod(url);
method.setDoAuthentication( true );
httpClient.executeMethod(method);
String s = method.getResponseBodyAsString();
System.out.println(s);
