簡要說明
本次主要說的是微信授權擷取使用者基本資訊，還有就是日志回報系統。利用微信自帶的消息及時通知開發人員程式的報錯。可達到快速收到問題解決問題，有助于建立一個可靠的風控體系
注意這裡代碼隻有隐性授權 顯性授權自己加上即可 原理一樣
系統告警通知是使用的微信模闆消息進行一個告警的通知
基本model 不同的架構稍微改改就可以直接用（如：緩存方法哪裡需要自己根據自己架構特點進行改動）

控制器總的授權調用
第一步
public function indexOp() {
if(empty($_COOKIE['unionid'])){
// 授權擷取使用者的unionid
$this->check_back_url();
// 開始調用授權
$wx_model = Model('wx_center');
$wx_model->set('redirect_uri',BASE_SITE_URL."/mobile/index.php?act=goods_wx&op=get_unionid");
$wx_model->silent_outh_step1();
}else{
// 直接傳回
header('Location: '.$this->check_back_url());
}
}
第二步 $re = $wx_model->silent_outh_step2()->get_user_info(); 就是傳回使用者的基本資訊
/**
* 微信擷取使用者的資訊
*/
public function get_unionidOp() {
$wx_model = Model('wx_center');
$wx_model->set('code',$_GET['code']);
$re = $wx_model->silent_outh_step2()->get_user_info();
if(empty($re)||!$re['unionid']){
echo '<meta charset="utf-8">';
die('<center><h1>抱歉，您的網絡逾時，請稍後重試</h1></center>');
}
$_SESSION['my_userinfo'] = $re;
setcookie("unionid",$re['unionid'],time()+365*3600*12,'/');
header('Location: '.htmlspecialchars_decode(urldecode($_COOKIE['GobackUrl'])));die;
}
告警消息的發送demo
$join_ceshi['商城告警測試'] = '成功成功';
$join_ceshi['登陸錯誤'] = '10分鐘多個注冊導緻系統故障';
$join_ceshi['訂單告警'] = '10分鐘内10000個下單';
$join_ceshi['下單錯誤'] = '參數錯誤';
$wx_model->make_log('這是一條測試資料',$join_ceshi,'notice',$re['openid']);
這個是我自己架構中model的調用 （邏輯處理model 類似于ThinkPHP中的大D方法）
$wx_model = Model('wx_center');
