Fastadmin/thinkphp 微信登录授权 Demo

由于经常用这些就搞个示例方便调用吧！

这是index里面的文件

到时候就直接访问 /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'])){
                //存数据库
                $this->add_Wxuser($user);//获取到微信用户  存数据

                // 然后继续操作
            }else{
               $this->success('error', $user);
            }

        }

    }

    public function add_Wxuser($user){
        //在你的数据库 添加用户信息
        dump($user);
    }



}

里面加载的类文件（QQ496631085）

文件名Wxsdk.php 放在extendfast目录下面看框架及版本定义
