小女子求救：如何取得IE地址栏中的地址！

Question

String rname = "";
        if (request.getPathInfo() != null) {
            rname = request.getPathInfo().substring(1);
        }
        if (rname.indexOf('/') > 0) {
            rname = rname.substring(0, rname.indexOf('/'));
        }
        return rname;

Answer 1

  不行，request.getPathInfo()的值是空的！：（

Answer 2

request.getRequestURL() 应该是可以的阿
这与你是否安装了apache应该没有关系
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;public class RequestHeaderExample extends HttpServlet {    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
    {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        Enumeration e = request.getHeaderNames();
        while (e.hasMoreElements()) {
            String name = (String)e.nextElement();
            String value = request.getHeader(name);
            out.println(name + " = " + value);
        }
    }
}
运行上面的servlet看看其中是否可以取得地址

Answer 3

不能吧！连查j2ee-doc的想法都没有！看一下api-doc全有了！把里面所有有Path, URI, URL的函数试一次，全有了！

Answer 5

request.getRequestURI() + "?" + request.getQueryString();
这样就可以了。

Answer 6

request.getRequestURI() + "?" + request.getQueryString();这个应该是可以的哟

Answer 7

request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort() 
+ request.getRequestURI()效果等同与window.location
