读取multipart / form-data请求PHP7

Question

如何从multipart / form-data请求中获取原始HTTP请求？

请求未写入test.log ..仅保存Response:？

客户端可以上传文件等，我需要检查用户是否gzip二进制数据部分..如果不是我需要抛出错误

请求

$boundary = 'jlasdifj439';
$field1 = json_encode(['test' => 123]);
$body = '--'.$boundary."\r\n"
    .'Content-Disposition: form-data; name="json"'."\r\n"
    .'Content-Type: application/json'."\r\n"
    .'Content-Length: '.strlen($field1)."\r\n\r\n"
    .$field1."\r\n"
    .'--'.$boundary.'--';

$socket = curl_init();
curl_setopt_array($socket, [
    CURLOPT_POST            => true,
    CURLOPT_RETURNTRANSFER  => true,
    CURLOPT_VERBOSE         => true,
    CURLOPT_ENCODING        => '',
    CURLOPT_HTTP_VERSION    => CURL_HTTP_VERSION_2_0,
]);
curl_setopt($socket, CURLOPT_URL, 'https://my-url');
curl_setopt($socket, CURLOPT_HTTPHEADER, [
    'Content-Type: multipart/form-data; boundary='.$boundary,
]);
curl_setopt($socket, CURLOPT_POSTFIELDS, $body);
if(!$response = curl_exec($socket)){
    echo "ERROR!";
}

echo $response;

响应

$body = file_get_contents('php://input');
file_put_contents('/var/www/test.log', "Response:\n".$body);

test.log中

Response:

curl verbose
