1，PHP登录代码【login.php】

完整代码如下

<?php


$name=$_POST[‘pname‘];

$password=$_POST[‘ppwd‘];


if ($name && $password){


$conn=mysql_connect("xxxxxxxx","Mysql用户名","MYsql密码") or die("SomeConstrError");


mysql_select_db("getfh_15188775_linmdb");


mysql_query("set names utf8");


$sql="SELECT * FROM `getfh_15188775_linmdb`.`u_table` WHERE pname = ‘$name‘ and ppwd=‘$password‘";
 $res = mysql_query($sql);
 $rows=mysql_num_rows($res);


mysql_query($sql);

  if($rows){
     echo "Login--okokok--";
  
    }
     else{
      echo "error--1--";
     }
}
else {
 echo "error--2--";
}



?>

上传到虚拟主机服务器，代码很简单，不懂的自己百度PHP基础，网上一堆

2，Unity3D登录代码【Login.cs】

代码如下

using UnityEngine;
using System.Collections;

public class Login : MonoBehaviour {

    public string  Server_url = "";
    
    // Use this for initialization
    void Start ()
    {
        Server_url = "http://linm123.getfreehosting.co.uk/login.php";
    }
    
    // Update is called once per frame
    void Update ()
    {
    
    }
    
    public string Pname = "";
    public string Ppwd = "";
    public bool isClicked;
    
    
    public string TempMessage="--Login-XX--";
    void OnGUI ()
    {
        
        Pname = GUI.TextField (new Rect (130, 0, 100, 50), Pname);
        
        Ppwd = GUI.TextField (new Rect (130, 60, 100, 50), Ppwd);
        
        if (isClicked == false) {
            if (GUI.Button (new Rect (130, 120, 100, 50), "Login")) {
                
                isClicked = true;
                
                StartCoroutine (RegisterData ());
            }
            
        }
        
        GUI.Label( new Rect  (130, 180, 150, 50), TempMessage );
        
        
    }
    
    WWWForm form;
    WWW logindownload;

    IEnumerator RegisterData ()
    {
        form = new WWWForm ();
    
        form.AddField ("pname", Pname);
    
        form.AddField ("ppwd", Ppwd);

        // Create a download object
        //创建一个下载对象
        logindownload = new WWW (Server_url, form);

        // Wait until the download is done
        //等待直到下载完成
        yield return logindownload;
        
        
        Debug.Log ("LoginOK - - " + logindownload.text);
     
         TempMessage = logindownload.text;
         isClicked = false;
    }
}

运行测试

输入用户名 admin

密码 123

bubuko.com,布布扣

点击登录

bubuko.com,布布扣

服务器给我们相应 Login-okokok-了，证明账号密码正确

下面我们再来看登录并读取数据

3，PHP登录并循环读取表中所有数据代码【logingetdata.php】

完整代码如下

<?php


$name=$_POST[‘pname‘];

$password=$_POST[‘ppwd‘];

if ($name && $password){


$conn=mysql_connect("XXXXMYSQL服务器地址","gMysql账号","MYsql密码c") or die("SomeConstrError");


mysql_select_db("getfh_15188775_linmdb");


mysql_query("set names utf8");


$sql="SELECT * FROM `getfh_15188775_linmdb`.`u_table` WHERE pname = ‘$name‘ and ppwd=‘$password‘";
 $res = mysql_query($sql);
 $rows=mysql_num_rows($res);


mysql_query($sql);

  if($rows){
   /*  
echo "Login--okokok--";
  
*/

$dbh = @mysql_connect("XXXXMYSQL服务器地址","gMysql账号","MYsql密码c"); 

if(!$dbh) { die("error"); } 
@mysql_select_db("getfh_15188775_linmdb", $dbh); 

$q = "SELECT * FROM u_table"; 

$rs = mysql_query($q, $dbh); 

while($row = mysql_fetch_row($rs)) { 

echo "name--:".$row[0]."--pwd--:".$row[1]."\r\n--- "; } 

/*ssssssend*/ 
} 
else

{ echo "error--1--"; } }
 else { echo "error--2--"; } 

?>

代码原理就是先检查用户名密码是否正确，如果进入到正确的 if语句里面，再检索数据库表中所有数据，循环所有的数据传回

上传该文件到你的虚拟主机PHP服务器

4，Unity3D登录并读取所有数据代码【LoginGetAllData.cs】

using UnityEngine;
using System.Collections;

public class LoginGetAllData : MonoBehaviour {

    public string  Server_url = "";
    
    // Use this for initialization
    void Start ()
    {
        Server_url = "http://linm123.getfreehosting.co.uk/logingetdata.php";
    }
    
    // Update is called once per frame
    void Update ()
    {
    
    }
    
    public string Pname = "";
    public string Ppwd = "";
    public bool isClicked;
    
    
    public string TempMessage="--GetAllData-XX--";
    void OnGUI ()
    {
        
        Pname = GUI.TextField (new Rect (310, 0, 100, 50), Pname);
        
        Ppwd = GUI.TextField (new Rect (310, 60, 100, 50), Ppwd);
        
        if (isClicked == false) {
            if (GUI.Button (new Rect (310, 120, 100, 50), "LoginAllData")) {
                
                isClicked = true;
                
                StartCoroutine (RegisterData ());
            }
            
        }
        
        GUI.TextArea( new Rect  (50, 220, 450, 200), TempMessage );
        
        
    }
    
    WWWForm form;
    WWW logindownload;

    IEnumerator RegisterData ()
    {
        form = new WWWForm ();
    
        form.AddField ("pname", Pname);
    
        form.AddField ("ppwd", Ppwd);

        // Create a download object
        //创建一个下载对象
        logindownload = new WWW (Server_url, form);

        // Wait until the download is done
        //等待直到下载完成
        yield return logindownload;
        
        
        Debug.Log ("GetOK - - " + logindownload.text);
     
         TempMessage = logindownload.text;
         isClicked = false;
    }
}
