微信公众号生成带参数二维码

/*** 生成推广二维码*/public function create_qrcode() {$res = Db::name("user")->field("reffer_code,openid")->where("id", $this->auth->id)->find();// QR_SCENE QR_STR_SCENE 临时二维码 QR_LIMIT_SCENE QR_LIMIT_STR_SCENE 永久二维码$arr = ['action_name' => 'QR_STR_SCENE','action_info' => ['scene' => ['scene_str' => $res['reffer_code']]]];$data = json_encode($arr);$url = 'https://api./cgi-bin/qrcode/create?access_token=' . $this->getAccessToken();$result = $this->CURLSend($url, 'post', $data);$results = json_decode($result, true);// echo "<pre>";var_dump( $url , $results );die;$qecodeUrl = 'https://mp./cgi-bin/showqrcode?ticket=' .

然后根据openid获取本人信息
