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： <rolerolename = " test " /><userusername = " a " password = " b " roles = " test " /> Step2)修改web.xml < security-constraint > < display-name > ExampleSecurityConstraint </ display-name > < web-resource-collection > < web-resource-name > ProtectedArea </ web-resource-name > <!-- Definethecontext-relativeURL(s)tobeprotected --> < url-pattern > /test/* </ url-pattern > <!-- Ifyoulisthttpmethods,onlythosemethodsareprotected --> < 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 > <!-- Anyonewithoneofthelistedrolesmayaccessthisarea --> < role-name > test </ role-name > </ auth-constraint > </ security-constraint > <!-- DefaultloginconfigurationusesBASICauthentication --> < login-config > < auth-method > BASIC </ auth-method > < realm-name > WebServiceForm-BasedAuthenticationArea </ 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： HttpClienthttpClient = new HttpClient();Credentialsdefaultcreds = new UsernamePasswordCredentials( " a " , " b " );httpClient.getState().setCredentials( " WebServiceForm-BasedAuthenticationArea " , " www.cat.cn " ,defaultcreds);Stringurl = " http://www.cat.cn/test/index.do " ;GetMethodmethod = new GetMethod(url);method.setDoAuthentication( true );httpClient.executeMethod(method);Strings = method.getResponseBodyAsString();System.out.println(s); 相关资源：Office2016专业增强版中文免费正式版(附安装教程)64位
