同一个历史协商接口里面两个数据

下面的media_id 就可以正常访问，但是上面带有%2F 的图片就无法访问

获取图片地址的代码如下

$stack = clone $this->builder->getDriver()->select()->getConfig('handler');
$stack->remove('verifier');
//  下载接口都是非标接口，要特殊搞一下 要 {+media_slot_url} 这样的语法结构
$response = $this->builder->chain('v3/merchant-service/images/{+media_slot_url}')->get([
    'handler' => $stack,
    'media_slot_url' => $mediaId,
]);

if ($response->getStatusCode() == 200) {
    return [current($response->getHeader('Content-Type')), base64_encode($response->getBody()->getContents())];
}
