Php 未过帐的Curl POST字段

我已经验证了

$requestDom->saveXml（）

正在返回有效的XML，但是在目标URL上我有print\r（$\u POST），它没有收到任何内容。我是不是遗漏了什么-\

    $connection = curl_init();
    curl_setopt($connection, CURLOPT_POSTFIELDS, array(
        'xml' => $requestDom->saveXml()
    ));
    curl_setopt($connection, CURLOPT_HEADER, false); //with or without this option, it doesn't work
    curl_setopt($connection, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($connection, CURLOPT_POST, true);
    curl_setopt($connection, CURLOPT_URL, 'http://sample.com');

    $response = curl_exec($connection);

---

我可以重现这个问题。在EFnet上的#php.pecl频道寻求帮助。

经过进一步研究，我发现将xml发布到目标URL的正确方法是

$connection = curl_init();
curl_setopt($connection, CURLOPT_POSTFIELDS, $requestDom->saveXml());
curl_setopt($connection, CURLOPT_HEADER, false); //with or without this option, it doesn't work
curl_setopt($connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($connection, CURLOPT_POST, true);
curl_setopt($connection, CURLOPT_URL, 'http://sample.com');

$response = curl_exec($connection);

然后在接收此信息的文件上，使用：

            $post = file_get_contents("php://input");
            $request = simplexml_load_string($post);
