Mailchimp v3 - Retrieve only members names and email from an specific list

我想从特定列表中检索成员数组。但是，我只对他们的名字，电子邮件以及他们的ID感兴趣，而不是一个大的回应。

我得到了这段代码，可以很好地检索列表中成员的每个详细信息

$ch = curl_init(REQUEST_URL.$list.'/members/');
  curl_setopt($ch, CURLOPT_USERPWD, 'user:' . API_KEY);
  curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $result = curl_exec($ch);
  $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $error = curl_error ( $ch );
  curl_close($ch);

但是，如果我尝试在请求 URL 中添加所需的字段，则会收到 422 错误：

"请求的字段无效" "请求的某些字段无效： member.first_name"

提出此请求的正确方法是什么？仅特定列表中所有成员中的某些字段？

谢谢你们！

以下是传递必填字段的方法

$ch = curl_init(REQUEST_URL.$list.'/members/?fields=members.id,members.email_address');
  curl_setopt($ch, CURLOPT_USERPWD, 'user:' . API_KEY);
  curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $result = curl_exec($ch);
  $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $error = curl_error ( $ch );
  curl_close($ch);
