Convert HTTP_Request2 to wp_remote_post

Question

I have some php in WordPress using HTTP_Request2 that I'm struggling to convert to use wp_remote_post.

This code currently works:

$xmlCustomerDataByAuthorLicenseID = '
    <GetCustomerDataByAuthor>
        <AuthorID>ABC123</AuthorID>
    </GetCustomerDataByAuthor>';
$requestDataLicense = new HTTP_Request2(
     $urlCustomerDataByAuthor,HTTP_Request2::METHOD_POST);
$requestDataLicense->addPostParameter(
    'xml', $xmlCustomerDataByAuthorLicenseID);  
$requestDataLicenseResponse = $requestDataLicense->send();
$xmlDataParsed = simplexml_load_string(
    $requestDataLicenseResponse->getBody());
    
foreach ($xmlDataParsed->{"Customer"} as $individualCustomer)
{
   $customerEmail = strtolower(trim($individualCustomer->Email));
}

This is my failed attempt:

$requestDataLicenseResponse = wp_remote_post(
        $urlCustomerDataByAuthor, 
        array(
            'headers' => array(
                'Content-Type' => 'text/xml'
            ),
            'body' => array('xml' => $xmlCustomerDataByAuthorLicenseID),
            'sslverify' => false
        )
    );
$xmlDataParsed = simplexml_load_string($requestDataLicenseResponse ->getBody());

foreach ($xmlDataParsed->{"Customer"} as $individualCustomer)
    {
       $customerEmail = strtolower(trim($individualCustomer->Email));
    }

The expect input for the service is

<GetCustomerDataByAuthor xmlns="">
<AuthorID>value</AuthorID>
</GetCustomerDataByAuthor>

Answer 1

The issue might be with how you're passing the XML data in the request body. In the wp_remote_post function try this"

    $xmlCustomerDataByAuthorLicenseID = '<GetCustomerDataByAuthor><AuthorID>ABC123</AuthorID></GetCustomerDataByAuthor>';

$response = wp_remote_post(
    $urlCustomerDataByAuthor,
    array(
        'method' => 'POST',
        'headers' => array(
            'Content-Type' => 'text/xml'
        ),
        'body' => $xmlCustomerDataByAuthorLicenseID,
        'sslverify' => false
    )
);

if (wp_remote_success($response)) {
    $xmlDataParsed = simplexml_load_string($response['body']);

    foreach ($xmlDataParsed->{"Customer"} as $individualCustomer) {
        $customerEmail = strtolower(trim($individualCustomer->Email));
    }
}

Answer 2

I figured it out.

$requestDataLicense = new HTTP_Request2($urlCustomerDataByAuthor,HTTP_Request2::METHOD_POST);
$requestDataLicense->addPostParameter('xml', $xmlCustomerDataByAuthorLicenseID);    
$requestDataLicenseResponse = $requestDataLicense->send();
$xmlDataParsed = simplexml_load_string($requestDataLicenseResponse->getBody())

converts to

$requestDataLicense = wp_remote_post(
    $urlCustomerDataByAuthor,
    array(
        'body' => array('xml' => $xmlCustomerDataByAuthorLicenseID)
    )
);      

$retrieveBody = wp_remote_retrieve_body($requestDataLicense);
$xmlDataParsed = simplexml_load_string($retrieveBody);
