从URL复制的文件将被截断

Question

我在复制文件时遇到问题.我的代码:

$file = "https://www.ilportaleofferte.it/portaleOfferte/resources/opendata/csv/offerteML/2019_1/PO_Offerte_G_MLIBERO_20190130.xml";

$newfile = $_SERVER['DOCUMENT_ROOT'] . '/input/PO_Offerte_G_MLIBERO_20190130.xml';

if(copy($file, $newfile)) {
    echo "salvato<br>";
} else {
    echo "ERROR inport file PO_Offerte_".$data.".".$ext."<br>";
    die;
}

copy() 如果是,则创建文件但文件末尾的某些行丢失...文件为3.6MB,文件末尾的0.3缺失...

如果我手动下载文件一切都很好,所以源完成...

如果我获得文件内容,我实际上有同样的问题file_get_contents(),我尝试使用文件写入功能将其保存在文件中...

我不认为upload_max_filesize并且post_max_size实际参与其中,copy()但它们是20MB设置

任何提示？

谢谢

我能够使用file_get_contents 和强制HTTP/1.1协议:

$context = stream_context_create([
    'http' => [
      'protocol_version' => '1.1',
      'header' => 'Connection: Close'
    ],
]);
$content = file_get_contents('https://www.ilportaleofferte.it/portaleOfferte/resources/opendata/csv/offerteML/2019_1/PO_Offerte_G_MLIBERO_20190130.xml', false, $context);
file_put_contents('document.xml', $content);

话虽如此,我建议使用CURL:

$ch = curl_init();
$curlopts = array();
$curlopts[CURLOPT_RETURNTRANSFER] = true;
$curlopts[CURLOPT_VERBOSE] = true;
$curlopts[CURLOPT_URL] = 'https://www.ilportaleofferte.it/portaleOfferte/resources/opendata/csv/offerteML/2019_1/PO_Offerte_G_MLIBERO_20190130.xml';
curl_setopt_array($ch, $curlopts);
$content = curl_exec($ch);
file_put_contents('document.xml', $content);
curl_close($ch);
