thinkphp5.0 + 微信分享

gushengyan 2018-05-09 10:24 原文

因为是做微信公众号好友助力的活动和游戏,所以有个需要分享的页面,判定谁分享出去的,然后谁帮助了好友,和之前获取userinfo的一起贴出来.

1.入口文件(名字随便取,你开心就好.下面只贴文件里的方法)

    //获取用户头像和微信号
    public  function getUserInfo(){
//        $appid='wxa037f5cede358c84';
//        $appsecret='e4cdd89734bae590bce8abbcfda82940';

        $appid = $app['appid'];
        $appsecret = $app['appsecret'];

        if(!$appid || !$appsecret){
            self::alter("请配置appid和appsecret");exit;
        }

            $request=Request::instance();
            $code=$request->param('code');
            if (!$code) {

            } else {
