怎样能把浏览器地址栏中正确的路径弄错乱码

Question

比如说"http://localhost:8084/LabSite/NewJplusServlet.jsp?mode=SHOWLIST&page=1 
把它用URLEncoder.encode("http://localhost:8084/LabSite/NewJplusServlet.jsp?mode=SHOWLIST&page=1","UTF-8")变成乱码   然后放到浏览器地址栏中   然后再后台解码进行操作，怎么实现  求大神指导

Answer 1

你想问的是什么解码吗？可以用URLDecoder.decode()方法

Answer 2

你在超链接里面的url加密，后台解密这个url请求就行了

Answer 3

你是想说以这样post的方式提交请求么？public static void main(String[] args) {
  URL url = null;
  HttpURLConnection httpurlconnection = null;
  try {
   url = new URL("http://www.ip138.com/ips.asp");
   httpurlconnection = (HttpURLConnection) url.openConnection();
   httpurlconnection.setDoInput(true);
   httpurlconnection.setDoOutput(true);   httpurlconnection.setRequestMethod("POST");
   httpurlconnection.setRequestProperty("Content-Type",
     "application/x-www-form-urlencoded");   String username = "ip=192.168.0.1";
   httpurlconnection.getOutputStream().write(username.getBytes());   httpurlconnection.getOutputStream().flush();
   httpurlconnection.getOutputStream().close();
   int code = httpurlconnection.getResponseCode();
   System.out.println("code    " + code);   if (code == 200) {    String cookie = httpurlconnection.getHeaderField("Set-Cookie ");
    System.out.println(cookie);
    // httpurlconnection.setRequestProperty( "Cookie", cookie);    DataInputStream in = new DataInputStream(httpurlconnection
      .getInputStream());
    int len = in.available();
    byte[] by = new byte[len];
    in.readFully(by);
    String rev = new String(by);
    System.out.println(rev);
    in.close();
   }
  } catch (Exception e) {
   e.printStackTrace();
  } finally {
   if (httpurlconnection != null) {
    httpurlconnection.disconnect();
   }
  }
 }

我是想把网址的跳转的正确路径给掩盖住   比如说要跳转到http://localhost:8084/LabSite/NewJplusServlet.jsp?mode=SHOWLIST&page=1  这个页面    然后我把他用URLEncoder.encode("http://localhost:8084/LabSite/NewJplusServlet.jsp?mode=SHOWLIST&page=1","UTF-8"); 这个乱码后    然后我浏览这个网页  浏览器网址只会显示http%3A%2F%2Flocalhost%3A8084%2FLabSite%2FNewJplusServlet.jsp%3Fmode%3DSHOWLIST%26page%3D1 这路径给你   怎么实现
