java request擷取路徑

標籤：結果   res   out   tom   nbsp   gets   string   get   port   

從Request對象中可以擷取各種路徑資訊，以下例子：

假設請求的頁面是index.jsp,項目是WebDemo，則在index.jsp中擷取有關request對象的各種路徑資訊如下

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

String remoteAddress=request.getRemoteAddr();

String servletPath=request.getServletPath();

String realPath=request.getRealPath("/");

String remoteUser=request.getRemoteUser();

String requestURI=request.getRequestURI();

 

out.println("path:"+path+"<br>");

out.println("basePath:"+basePath+"<br>");

out.println("remoteAddr:"+remoteAddress+"<br>");

out.println("servletPath:"+servletPath+"<br>");

out.println("realPath:"+realPath+"<br>");

out.println("remoteUser:"+remoteUser+"<br>");

out.println("requestURI:"+requestURI+"<br>");

 

結果：

path:/WebDemo
basePath:http://localhost:8683/WebDemo/
remoteAddr:127.0.0.1
servletPath:/index.jsp
realPath:D:\apache-tomcat-6.0.13\webapps\WebDemo\
remoteUser:null
requestURI:/WebDemo/index.jsp
