PHP |卷曲 |文档中的 API 请求示例

Question

请帮助我理解 API 的文档。 我需要一个 PHP 示例，说明如何将 CURL 用于此类文档描述以准备正确的 POST 请求。 拜托！

POST /api_service/PublicAPI/createRegistry HTTP/1.1
Host: test-api.api_service:8742
Content-Type: application/xml
Authorization: Basic (as a partner)
<api_service:createRegistry xmlns:api_service="http://api_service">
    <api_service:registryID>?</api_service:registryID>
    <api_service:orders>
        <api_service:order>
            <api_service:orderID>?</api_service:orderID>
            <api_service:info>
                <api_service:accountNumber>?</api_service:accountNumber>
            </api_service:shipperInfo>
        </api_service:order>
    </api_service:orders>
</api_service:createRegistryShipment>

这是我的尝试，但我总是收到错误：400 Bad Request。普通的 HTTP 请求已发送到 HTTPS 端口

$fields = array(
        'createRegistry' => array(
            'registryID'   => '05/03/2023 17:29:05',
            'orders' => array(
                'order' => array(
                    'orderID' => '12345678',
                    'info' => array(
                        'accountNumber' => '12345678'
                    )
                )
            )
        )
    );
$fields_string = http_build_query($fields);
$curl = curl_init();
curl_setopt_array($curl, array(
        CURLOPT_PORT => "8742",
        CURLOPT_URL => "http://test-api.api_service:8742/npi/PublicAPI/createRegistry ",
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_TIMEOUT => 30,
        CURLOPT_POSTFIELDS => $fields_string,
        CURLOPT_HTTPHEADER => array(
            'POST: /npi/PublicAPI/createRegistryShipment HTTP/1.1', 
            'Host: test-api.api_service:8742',
            'Content-Type: application/xml',
            'Authorization:' . base64_encode('Username:Password')
        )
    ));

    $response = curl_exec($curl);
    $err = curl_error($curl);

    curl_close($curl);
var_dump($response);
