Unity 3D同PHP数据交互案例

会飞的鱼

Unity 3D同PHP数据交互案例
1,创建一个数据库表,使用MySql数据库.创建代码如下:
CREATE TABLE `scores` ( `id` INT( 10 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,

`name` VARCHAR( 30 ) NOT NULL ,

`password` VARCHAR( 50 ) NOT NULL

) ENGINE = innodb;
2,向数据库表中插入内容:
INSERT INTO `scores` ( `id` , `name` , `password` )

VALUES (

NULL , 'haiweisky', MD5( 'aaaaaa' )

);
3,创建一个验证用户基本信息的PHP页面，页面名字是：check_scores.php
       <?
// 联接数据库
$host = "localhost"; //主机名
$user = "root"; //用户名
$password = ""; //密码
$dbname = "unity3dTest"; //数据库名称
mysql_connect($host, $user, $password) or die("Cant connect into database");
mysql_select_db($dbname)or die("Cant connect into database");
// =============================================================================
// PROTECT AGAINST SQL INJECTION and CONVERT PASSWORD INTO MD5 formats
function anti_injection_login_senha($sql, $formUse = true)
{
$sql = preg_replace("/(from|select|insert|delete|where|drop table|show tables|,|'|#|*|--|\)/i","",$sql);
$sql = trim($sql);
$sql = strip_tags($sql);
if(!$formUse || !get_magic_quotes_gpc())
$sql = addslashes($sql);
$sql = md5(trim($sql));
return $sql;
}
// THIS ONE IS JUST FOR THE NICKNAME PROTECTION AGAINST SQL INJECTION
function anti_injection_login($sql, $formUse = true)
{
$sql = preg_replace("/(from|select|insert|delete|where|drop table|show tables|,|'|#|*|--|\)/i","",$sql);
$sql = trim($sql);
$sql = strip_tags($sql);
if(!$formUse || !get_magic_quotes_gpc())
$sql = addslashes($sql);
return $sql;
}
// =============================================================================
$unityHash = anti_injection_login($_POST["myform_hash"]);
$phpHash = "hashcode"; // same code in here as in your Unity game
$nick = anti_injection_login($_POST["myform_nick"]); //I use that function to protect against SQL injection
$pass = anti_injection_login_senha($_POST["myform_pass"]);
/*
you can also use this
$nick = $_POST["myform:_nick"];
$pass = $_POST["myform_pass"];
*/
if(!$nick || !$pass) {
    echo "npe";//昵称或密码不能为空。
} else {
    if ($unityHash != $phpHash){
        echo "HASH code is diferent from your game, you infidel.";
    } else {
        $SQL = "SELECT * FROM scores WHERE name = '" . $nick . "'";
        $result_id = @mysql_query($SQL) or die("DATABASE ERROR!");
        $total = mysql_num_rows($result_id);
        if($total) {
            $datas = @mysql_fetch_array($result_id);
            if(!strcmp($pass, $datas["password"])) {
                //echo "LOGADO - PASSWORD CORRECT";
                echo "success";
            } else {
                echo "npw"; //昵称或密码错误
            }
        } else {
            echo "nfn";//没此用户
        }
    }
}
// Close mySQL Connection
mysql_close();
?>
4，新建一个Unity 3D项目,命名为myGame;新建一个Javascript文件，命名为phpUnity(点击Project面板上的Create按钮，点击Javascript,产生一个新的javascript,按F2为其命名为phpUnity).
       在phpUnity文件上编写如下代码：

private var formNick = ""; //登录名
private var formPassword = ""; //密码
var formText = ""; //根据判断显示信息
var yyyskin:GUISkin;
var URL = "http://localhost/unity_test/check_scores.php"; //提交的URL地址
var hash = "hashcode"; //change your secret code, and remember to change into the PHP file too

private var textrect = Rect (10, 150, 500, 100); //just make a GUI object rectangle

function OnGUI() {
       if(yyyskin){
              GUI.skin = yyyskin;
          GUI.Label( Rect (10, 10, 80, 20), "姓名:"); //text with your nick
          GUI.Label ( Rect (10, 30, 80, 20), "密码:" );
          formNick = GUI.TextField ( Rect (90, 10, 100, 20), formNick ); //here you will insert the new value to variable formNick
          formPassword = GUI.PasswordField ( Rect (90, 30, 100, 20), formPassword ,"*"[0], 25);
//same as above, but for password
          if ( GUI.Button ( Rect (10, 60, 100, 20) , "登录" ) ){ //just a button
              Login();
          }
          GUI.TextArea( textrect, formText );
   }
}
function Login() {
   var form = new WWWForm(); //创建一个WWWForm对象。
   form.AddField( "myform_hash", hash ); //add your hash code to the field myform_hash, check that this variable name is the same as in PHP file
   form.AddField( "myform_nick", formNick );
   form.AddField( "myform_pass", formPassword );
   var w = WWW(URL, form); //here we create a var called 'w' and we sync with our URL and the form
   yield w; //we wait for the form to check the PHP file, so our game dont just hang
   if (w.error != null) {
      print(w.error); //if there is an error, tell us
   } else {
              var return_data=w.data;
              if(return_data=="success"){
                     Application.ExternalEval("window.location.href='game.php?username="+formNick+"'");
              }else if(return_data=="npe"){
                     print("Test ok");
                     formText = "用户名或密码不能为空!"; //here we return the data our PHP told us
                           
              }else if(return_data=="nfn"){
                     formText="用户名不存在!";
              }else if(return_data=="npw"){
                     formText="用户名或密码不正确！";
              }
              w.Dispose(); //clear our form in game
   }
   formNick = ""; //just clean our variables
   formPassword = "";
  
   }
5. 此代码放在主相机内的游戏对象上。
