request.getURL()和request.getURI() 以及通过request获得路径相关大全

request.getURL()和request.getURI()

　　如果我的请求是：http://localhost:8080/ServletTest/servlet/Hello

　　request.getRequestURI() 返回值类似：/ServletTest/servlet/Hello

　　request.getRequestURL() 返回值类似：http://localhost:8080/ServletTest/servlet/Hello

　　再如：

　　request.getContextPath() = /ServletTest

　　request.getLocalAddr() = 127.0.0.1

　　request.getPathInfo() = null

　　request.getPathTranslated() = null

　　request.getRemoteAddr() = 127.0.0.1

　　request.getRequestURI() = /ServletTest/servlet/Hello

　　request.getScheme() = http

　　request.getServerName() = 127.0.0.1

　　request.getServletPath() = /servlet/Hello

　　request.getClass() = class ornnector.RequestFacade

　　request.getHeaderNames() = org.apache.tomcat.util.http.NamesEnumerator@1fb050c

　　request.getLocale() = zh_CN

　　request.getLocales() = org.apache.catalina.util.Enumerator@1088a1b

　　request.getParameterMap() = {}

　　request.getRequestURL() =

　　request.getUserPrincipal() = null

　　request.getParameterNames() = java.util.Hashtable$EmptyEnumerator@1db6942

　　request.getRealPath("newsPub") =

　　D:\zfsca\.metadata\.plugins\com.genuitec.eclipse.easie.tomcat.myeclipse\tomcat\webapps\ServletTest\newsPub

　　request.getRealPath("/") =

　　D:\zfsca\.metadata\.plugins\com.genuitec.eclipse.easie.tomcat.myeclipse\tomcat\webapps\ServletTest\
