日志记录类库 LogUtil.class.php

<?php
/**
 * 日志 类

 */
class LogUtil{
	public static function writeLog($text){
		// 调用 error_log() 的另一种方式:
		error_log($text."\r\n", 3, "./my-errors.log");
	}
}
?>

接下来就可以写控制器了

define("TOCKEN", "huigood520");       //定义TOCKEN常量  与微信公众号配置的一致
class weixinModule extends MainBaseModule
{
    //微信直连
    public function weixinConnect(){

    	$WeiXin = new \WeiXin();
        $token = TOCKEN;
        //echo $token;
    	$WeiXin->valid();
    	$reply = $WeiXin->responseMsg($postStr);
    }
