asp page url见代码
使用ie打开，输入错误信息会出现下列出错信息


*** This MemberID cannot be found ***

如果在url里直接加参数传过去，返回页面是无错误信息的

用如下代码，得到的html里面却不含出错信息，怀疑是否没能正确模拟
但是使用本机的tomcat作试验，这个方法可以post数据到jsp/servlet

老板交给我的任务，大家表鄙视我~.~


try {
      
      String urlstr = "http://www.gamenz.com/Membership/Member_Log_in.asp";
      String query = "MemberID=test&Password=test";

      URL url = new URL(urlstr);
      URLConnection uc = url.openConnection();

      uc.setDoOutput(true);
      PrintStream out = new PrintStream(uc.getOutputStream());
      out.println(query);
      out.close();

      DataInputStream in = new DataInputStream(uc.getInputStream());
      String line;
      while ((line = in.readLine()) != null) {
        System.out.println(line);
      }
    } catch (MalformedURLException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
