php 获取小程序二维码

我这里请求的接口是接口 B：适用于需要的码数量极多的业务场景
https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/qr-code.html这个是官方给的接口文档
下面是我的代码 需要注意的是accesstoken 存起来 设置过期时间 我这边是存在redis中

public static function wxapp_code($accesstoken,$address){
    //构建请求二维码参数
    //path是扫描二维码跳转的小程序路径，可以带参数?id=xxx
    //width是二维码宽度
    $qcode ="https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=$accesstoken";
    $param = json_encode(array("scene"=>$address[1],"page"=>$address[0],"width"=> 80));
    //POST参数
    $result = self::httpRequest( $qcode, $param,"POST");
    return $result;
}

//把请求发送到微信服务器换取二维码
    public static function httpRequest($url, $data='', $method='GET'){
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
//        curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
        if($method=='POST')
        {
            curl_setopt($curl, CURLOPT_POST, 1);
            if ($data != '')
            {
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            }
        }

        curl_setopt($curl, CURLOPT_TIMEOUT, 30);
        curl_setopt($curl, CURLOPT_HEADER, 0);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec($curl);
        curl_close($curl);
        return $result;
    }

//重新获取微信小程序access_token保证唯一性
public static function access_token(){
    //        配置APPID、APPSECRET
    $APPID = WEIXIN_OPENCOURSE_APPID;
    $APPSECRET =  WEIXIN_OPENCOURSE_APPSECRET;
    //获取access_token
    $access_token = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$APPID&secret=$APPSECRET";
    //缓存access_token
    $redis = SayRedis::get_instance('lists');
    //存俩个小时
    $operate_time = time();
    $json = self::httpRequest( $access_token );
    $json = json_decode($json,true);
    $redis->set('wxxcx_token'.WEIXIN_OPENCOURSE_APPID,$json["access_token"]);//access_token
    $redis->set('wxxcx_time',$operate_time);//access_token
    $accesstoken = $redis->get('wxxcx_token'.WEIXIN_OPENCOURSE_APPID);//access_token
    return $accesstoken;
}
