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 app\index\controller; use app\common\controller\Frontend; use fast\Wxsdk; 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extend\fast\目录下面 看框架及版本 定义

然后就可以继续操作了
