PHP修补程序产品PayPal目录API格式错误请求错误

Question

我有一个让我发疯的问题。我正在尝试使用PayPal目录API更新产品。这是一个相当基本的cURL调用，使用以下代码：

$authorization="Authorization: Bearer ".$authorization;

curl_setopt($ch, CURLOPT_URL, 'https://api.sandbox.paypal.com/v1/catalogs/products/RBW00002');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PATCH');
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"op": "replace", "path": "/description", "value": "xxx"}');
curl_setopt($ch, CURLOPT_POST, 1);

$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = $authorization;

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);

if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}

$editproduct= json_decode($result);

print_r($editproduct );
echo "<br><br>";

print_r($json);
echo "<br><br>";

unset($headers);
curl_close($ch);

但它总是返回以下错误：

stdClass对象（[名称]=

有人能帮忙吗？谢谢！

从更新产品详细信息的文档中，顶级项应该是一个带有[]括号的数组

'[
  {
    "op": "replace",
    "path": "/description",
    "value": "Premium video streaming service"
  }
]'
