Unity + PHP 互动多媒体项目的 微信公众号 模块实现

场景 :用户扫描公众号二维码,只有关注了公众号二维码才可以继续游戏

思路:

1.建一个自己的后台服务器,

2.微信公众平台设置后台服务器地址

3.用户扫描二维码之后,微信服务器会告诉后台服务器

4.服务器接收到微信服务器的消息,判断有用户关注事件之后修改Config.txt的内容为1, 1s 后修改回内容为0(后面需要修改为数据库)

5.Unity 每隔1s 去Get 这个服务器地址的 Config.txt的内容,如果为1,则判断为有用户关注

PHP

新建一个weixin.php 和一个 config.txt 

<?php
header('content-type:text/html;charset=utf-8');
//header("Content-Type:text/html;charset=gb2312");


define("TOKEN", "test"); //define your token
$wechatObj = new wechatCallbackapiTest();

  // $wechatObj->MyGetAccessToken();
if (!isset($_GET['echostr'])) {
	$wechatObj->responseMsg();
     // $wechatObj->getAccessToken();
    // $wechatObj->showAccessToken();    //本次执行showAccessToken()函数来显示access_token
     // $wechatObj->getUserOpenId();    //调用getUserOpenId()获取关注者openID列表

}else{
	$wechatObj->valid();
}

// require_once './phpServerWithUnityClient.php';
// $tool=new phpServerWithUnityClient();
// $tool->SendToUnity();



class wechatCallbackapiTest{

	private $access_token;
public function showAccessToken(){    //在浏览器中输出随机生成的access_token

	//echo "tocken = ".$this->access_token;
}

		$echoStr = $_GET["echostr"];
