下载地址链接：https://pan.baidu.com/s/1ramNa2o    密码：8ok8

2.把类文件放到第三方类中：  ThinkPHP\Library\Vendor\phpqrcode.php

3.首先微信公众平台账号有这个权限，没有的话去开通。

tp框架 中生成微信推广二维码

一切准备就绪开始上代码：

控制器里面方法代码为:

      //推广二维码
        public function extendewm()
        {   
            $user_id=I('get.id');//获取当前登录用户id,后以做二维码参数(scene_id)
            $usermobile=$_SESSION['usermobile'];//当前登录者用户手机号
            //获取access_token
            //请求url地址
            $appId = 'wxc7245e01b2b4b965';
            $appSecret = '5cb65e4111e750497e32fdf44c91a3b9';
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appId."&secret=".$appSecret;
            //初始化curl
            $ch = curl_init($url);
            //3.设置参数
            curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);//跳过证书验证
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
            //4.调用接口
            $res = curl_exec($ch);
            if(curl_errno($ch)){
                var_dump(curl_error($ch));
            }
            $resArr = json_decode($res,true);
            //5.关闭curl
            curl_close($ch);
            $access_token=$resArr['access_token'];
            //创建二维码ticket,根据当前登陆者角色分别生成不同的ticket,进而生成临时和永久二维码
            $usermobile=$_SESSION['usermobile'];//当前登录者用户手机号
            $user=M('user');
            $userdata=$user->where(array('tellphone'=>$usermobile))->find();
            $user_id=$userdata['id'];
            $role=$userdata['role'];
            //$arrrole=explode(",",$role);
            $url1="https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=".$access_token;
            if($role==2)//商家属性 
            {
                $dataforever = '{"action_name": "QR_LIMIT_SCENE", "action_info": {"scene": {"scene_id": "$user_id"}}}';//永久二维码请求数据(数字形式的场景值ID)
