此方法通用OCR的功能请求，不同的是功能请求接口，按照自己所需换一个接口地址即可：

<?php
global $_GPC, $_W;
//ocr请求地址
$url='http://style.iis7.com/uploads/2021/09/10165074599.png');
//编码后加入到请求参数中
// $params['image'] = base64_encode($image_data);
$params['image'] = '/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAUEBAQEAwUEBAQGBQUGCA0ICAcHCBALDAkNExAUExIQ
