Send在第二个条件下不能工作在php中提交它的结果给android

我编写了以下代码。由于java代码是通过POST的方式发送数据的，所以不应执行php文件中的第一个条件，而应执行第二个条件。但是我在android上看不到echo "$name";的结果。但是当我在第一条件下使用POST而不是GET时，我可以在android中看到第一条件的结果。

 public  void  GetText()  throws UnsupportedEncodingException
    {
        // Get user defined values
        Name = fname.getText().toString();
        Email   = email.getText().toString();
        Login   = login.getText().toString();
        Pass   = pass.getText().toString();
        // Create data variable for sent values to server
        String data = URLEncoder.encode("name", "UTF-8")
                + "=" + URLEncoder.encode(Name, "UTF-8");
        data += "&" + URLEncoder.encode("email", "UTF-8") + "="
                + URLEncoder.encode(Email, "UTF-8");
        data += "&" + URLEncoder.encode("user", "UTF-8")
                + "=" + URLEncoder.encode(Login, "UTF-8");
        data += "&" + URLEncoder.encode("pass", "UTF-8")
                + "=" + URLEncoder.encode(Pass, "UTF-8");
        String text = "";
        BufferedReader reader=null;
        // Send data
        try
        {
            // Defined URL  where to send data
            URL url = new URL("http://127.0.0.1:8080/apps/reg.php");
            // Send POST data request
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
            wr.write( data );
            wr.flush();
            // Get the server response
            reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line = null;
            // Read Server Response
            while((line = reader.readLine()) != null)
            {
                // Append server response in string
                sb.append(line + "'n");
            }

            text = sb.toString();
        }
        catch(Exception ex)
        {
        }
        finally
        {
            try
            {
                reader.close();
            }
            catch(Exception ex) {}
        }
        // Show response on activity
        content.setText( text  );
    }

和

<?php 
if ($_SERVER["REQUEST_METHOD"] == "GET") {     
$name   = urldecode($_POST['name']);
       $user   = urldecode($_POST['user']);
       $email  = urldecode($_POST['email']);
       $pass   = urldecode($_POST['pass']);
       print " ==== POST DATA =====
       Name  : $name
       Email : $email
       User  : $user
       Pass  : $pass"; 
 }
else if($_SERVER["REQUEST_METHOD"] == "POST") { echo "$name"; }
?>
