Unity+PHP+MySQ实现用户登录注册

转至（https://blog.csdn.net/MIYIshi/article/details/68950547）

PHP脚本如下：

<?php
//得到提交的用户名和密码
$uname = $_POST['uname'];//改成你自己数据库的字段
$upass = $_POST['upass'];//改成你自己数据库的字段
//action是用来判断是注册还查询
$action = $_POST['action'];

//你自己的数据库地址
$conn = mysql_connect("127.0.0.1","root","1234");
if(!$conn)
{
die("error");
}

//改成你自己的数据库名称
$result = mysql_select_db("lijia",$conn);
if(!$result)
{
mysql_close($conn);
die("error");
}

//判断用户是登录还是注册
if($action == "login")
{
//匹配用户
$sql = "select *from t_user where uname='".$uname."' and upass='".$upass."'";

//运行
$rs=mysql_query($sql);
if(!$rs)
{
mysql_close($conn);
die("error");
}
$recordCount=mysql_num_rows($rs);
if($recordCount>0)
{
echo "success";
}
else
{
echo "error";
}
}
else if($action == "regist")
{
//设定字符集
$sql = "set names utf8";
//运行
mysql_query($sql);

//查看用户是否存在
$sql = "select *from t_user where uname='".$uname."'";
//运行
$rs=mysql_query($sql);
if(!$rs)
{
mysql_close($conn);
die("error");
}
//获得数据库行数
$recordCount = mysql_num_rows($rs);
if($recordCount>0)
{
mysql_close($conn);
die("exist");
}else
{
//如果不存在就写入数据库
$sql = "insert into t_user(uname,upass) values('".$uname."','".$upass."')";
//运行
$rs=mysql_query($sql);
if(!$rs)
{
mysql_close($conn);
die("error");
}
else
{
echo "success";
}

}
//如果存在就提示

}
else
{
echo "error!";
}

//关闭数据库
mysql_close($conn);
?>

Unity界面如下：

C#脚本如下：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

/// <summary>
/// 模拟用户登录
/// unity + PHP + MySQL
/// </summary>
public class Demo : MonoBehaviour
{
   public InputField Name;
   public InputField Pass;
   public Text ShowText;
   private string Url = "http://127.0.0.1/Unity/loginregist.php";
   bool action;
   // Use this for initialization
   void Start () {

   }

   // Update is called once per frame
   void Update () {

   }

   /// <summary>
   /// 登录
   /// </summary>
   public void Btn_Login()
   {
       action = true;
       CreatWFrom (Name.text, Pass.text,action);
   }

   /// <summary>
   /// 注册
   /// </summary>
   public void Btn_Regist()
   {
       action = false;
       CreatWFrom (Name.text, Pass.text,action);
   }

   /// <summary>
   /// 创建表单
   /// </summary>
   /// <param name="name">Name.</param>
   /// <param name="pass">Pass.</param>
   public void CreatWFrom(string name,string pass,bool action)
   {
       WWWForm form = new WWWForm ();
       form.AddField ("uname",name);
       form.AddField ("upass",pass);
       if (action == true) {
           form.AddField ("action", "login");
       } else {
           form.AddField ("action", "regist");
       }
       StartCoroutine (SendPost(Url,form));
   }

   /// <summary>
   /// 提交表单
   /// </summary>
   /// <returns>The post.</returns>
   /// <param name="url">URL.</param>
   /// <param name="wForm">W form.</param>
   IEnumerator SendPost(string url,WWWForm wForm){
       WWW www = new WWW (url,wForm);
       yield return www;
       if (www.error != null) {
           Debug.Log (www.error);
       } else {
           Debug.Log (www.text);

           if (action == false) {
               if (www.text == "success") {
                   ShowText.text = "注册成功";
               } else if (www.text == "exist") {
                   ShowText.text = "用户名存在";
               }
           } else {
               if (www.text == "success") {
                   ShowText.text = "登录成功";
               } else if (www.text == "error") {
                   ShowText.text = "登录失败";
               }
           }

           Invoke ("ShowTextNull",1);
       }
   }

   void ShowTextNull(){
       ShowText.text = "";
   }
}

完美！
