如何使用cURL在PHP中创建PATCH请求？

Question

我必须使用PhP cURL发出PATCH请求.我找不到任何文档,所以我尝试了以下但是它没有用.

$data = "{'field_name': 'field_value'}";
$url = "http://webservice.url";
$headers = array('X-HTTP-Method-Override: PATCH');
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($curl);
curl_close($curl);

知道为什么这不起作用吗？我该如何解决？

编辑: 我正在连接到RESTful Web服务.它为成功请求返回HTTP/1.1 200.不成功的请求返回HTTP/1.1 403.我一直收到403.

我尝试将$ data更改为:

$data = "data={'field_name': 'field_value'}";

它没有改变结果.

Edit2: 最终的工作代码.

$data = "{'field_name': 'field_value'}";
$url = "http://webservice.url";
$headers = array('Content-Type: application/json');
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PATCH');
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($curl);
curl_close($curl);

Answer 1

curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PATCH'); 应该这样做.
