通过PHP插入SQL数据库

Question

My Java code produces link like this:

addscore.php&name=Namedd&score=0&hash=b61249d0207e4734879578733a86c3d6

A PHP file(addscore.php) should work with these informations and insert it into database with an sql query.

addscore.php:

<?php
         $db = mysql_connect("host", "root", "password") or die('Could not connect: ' . mysql_error());
         mysql_select_db("db1") or die('Could not select database');

         $score = (int)$_GET['score'];
         $hash = $_GET['hash'];
         $name = mysql_real_escape_string($_GET['name'], $db);
         $timestamp = date("Y-m-d H:i:s");
         $secretKey="mySecretKey";

         $real_hash = md5($score . $hash . $secretKey);

         if($real_hash == $hash) {
             $query = "INSERT INTO highscores (id, date, score, name) VALUES (NULL, '$timestamp', '$score', '$name')";
             $result = mysql_query($query) or die('Query failed: ' . mysql_error());
         }
?>

Java code gives an error message, could not submit score to server. If I try to open given url(see above) I get a Not found error.

UPDATE: Java code:

        String hash = "";
        String name = nameText.getText();
        try{
            MessageDigest md = MessageDigest.getInstance("MD5");
            md.update((name + score + HASH_SALT).getBytes());
            byte byteData[] = md.digest();

            StringBuffer sb = new StringBuffer();
            for (int i = 0; i < byteData.length; i++) {
                sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
            }
            hash = sb.toString();
        } catch (Exception e) {
            hash = "";
        }


        try {
            String urlParameters = PARAM_NAME + name + PARAM_SCORE + score + PARAM_HASH + hash;
            URL url = new URL(HIGHSCORES_ADD + urlParameters);
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.getInputStream();
            urlConnection.disconnect();
        } catch (Exception e){
            Gdx.app.log( "HighScores", "Could not submit score" + e.getMessage());
        } finally {
            ((Game)Gdx.app.getApplicationListener()).setScreen(new MainMenu());
        }

Answer 1

Your Address should be

addscore.php?name=Namedd&score=0&hash=b61249d0207e4734879578733a86c3d6

note to first & in the URL

In your Java code make sure to have ? between HIGHSCORES_ADD and urlParameters

when you fixed that if still have error in save data A good Idea is save your $query in a text or log file and try to check query in phpmyadmin

Another Thing you must note is Your insert is via php not with java ! update your question subject
