Fastadmin/thinkphp 微信登录授权 Demo
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
由于經常用這些就搞個示例方便調用吧！
這是index里面的文件
到時候就直接訪問 /index.php/index/index/wxindex
<?php
namespace appindexcontroller;
use appcommoncontrollerFrontend;
use fastWxsdk;
class Index extends Frontend
{
protected $noNeedLogin = '*';
protected $noNeedRight = '*';
// protected $layout = '';
public function _initialize(){
$this->appId = 'wx63c391768f362ca8'; //wxe6747dc052817254
$this->appSecret = '512ec5eb6117b86bcaccf3f10b45edc2'; //
}
public function wxindex()
{
$this->Wxsdk = new Wxsdk($this->appId,$this->appSecret);
if(!$this->Wxsdk->islogin()){
$user = $this->Wxsdk->login();
if(!empty($user['openid'])){
//存數據庫
$this->add_Wxuser($user);//獲取到微信用戶 存數據
// 然后繼續操作
}else{
$this->success('error', $user);
}
}
}
public function add_Wxuser($user){
//在你的數據庫 添加用戶信息
dump($user);
}
}
里面加載的類文件（QQ496631085）
文件名Wxsdk.php 放在extendfast目錄下面 看框架及版本定義
