hmrc增值税mtd-不接受发布

Question

尝试连接到HMRC MTD增值税申报表。

$access_token = $_SESSION['access_token'];

$handle = curl_init();

$url = "https://test-api.service.hmrc.gov.uk/organisations/vat/643159930/returns";

$postData = array(
  'Accept' => 'application/vnd.hmrc.1.0+json',
  'Authorization'  => 'Bearer '.$access_token,
  'Content-Type'    => 'application/json'
);

print_r($postData);

curl_setopt_array($handle,
  array(
     CURLOPT_URL => $url,
     // Enable the post response.
    CURLOPT_POST       => true,
    // The data to transfer with the response.
    CURLOPT_POSTFIELDS => $postData,
    CURLOPT_RETURNTRANSFER     => true,
  )
);

$data = curl_exec($handle);

curl_close($handle);

echo $data;

我收到回信：

Array（[Accept] => application / vnd.hmrc.1.0 + json [Authorization] =>承载3f69148194dfd7dffddc237cc1388df [Content-Type] => application / json）{“ code”：“ MISSING_CREDENTIALS”，“ message”： “未提供身份验证信息”}

知道为什么吗？
