先贴一下相关代码：

 //账号绑定

        }

        if( !$member_info ){
            if( Member::findOne([ 'mobile' => $mobile]) ){
                $this->renderJSON([], "手机号码已注册，请直接使用手机号码登录~~", -1);
            }

            $model_member = new Member();

            return $this->renderJSON([], "您的账号已被禁止，请联系客服解决~~", -1);
        }


        if( $openid ){ //用浏览器打开没有openid ,只有用微信打开才有openid
            $bind_info = OauthMemberBind::find()->where([ 'member_id' => $member_info['id'],'openid' => $openid,'type' => ConstantMapService::$client_type_wechat  ])->one();

            var_dump($bind_info);
            if( !$bind_info ){

            }
        }

//        if( UtilService::isWechat() && $member_info['nickname']  == $member_info['mobile'] ){
//            return $this->renderJSON([ 'url' => UrlService::buildMUrl( "/oauth/login",[ 'scope' => 'snsapi_userinfo' ] )  ],"绑定成功~~");
//        }
//        //todo设置登录态
//        $this->setLoginStatus( $member_info );
        return $this->renderJSON([ 'url' => UrlService::serverMUrl( "/default/index" )  ],"绑定成功~~");
    }

在网页上测试，因为没有openid ，所以虽然能正常跳转，也会提示“绑定成功”

在手机上测试，可以打印出openid

但点击绑定后：

点了绑定按钮后，没反应.....
