保存推送头文件以强制下载的远程文件 [英] Save remote file that pushes headers to force download

问题描述

我可以使用PHP下载远程文件，但是如何从一个将头插入的链接下载？我的意思是，您可以点击一些链接，它将强制下载并提供对话框来保存文件。如何使用PHP 下载并保存这样的东西？

I can download remote files using PHP but how do you download from a link that pushes headers out? I mean, you can click on some links and it will force a download and present you with dialog box to save the file. How can I download and save this sort of thing using PHP?

任何示例或教程链接将是非常好的，因为我找不到

Any examples or links to tutorials would be great since I couldn't find anything useful on this topic.

感谢您的帮助

<?php

set_time_limit(300);

// File to download
$remoteFile = $_GET['url'];

$file = fopen($remoteFile, "r");


if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
}
$line = '';

while (!feof ($file)) {
    $line .= fgets ($file, 4096);
}

//readfile($line);
file_put_contents('here2.mp4',  $line);

fclose($file);

?>

推荐答案

只是试图重现情况。 Gubmo是对的，这种下载方式适用于我的内容类型：应用程序/八位字节流和内容类型：应用程序/强制下载标题。

Just tried to reproduce situation. Gubmo is right, this download method works for me with Content-Type: application/octet-stream and Content-type: application/force-download headers.

如 here 所述HTTP 410意味着客户端请求的URL不再可用于该系统。这不是一个从未听说过的回应，而是不再在这里生活的回应。也许他们有某种反垄断制度。

As explained here, HTTP 410 means that URL requested by the client is no longer available from that system. This is not a 'never heard of it' response, but a 'does not live here any more' response. Maybe they have some kind of antileach system.

应该进行调查。如果他们需要Cookie - stream-context-create 可以帮忙或者也许他们检查引用。但是我几乎肯定问题不在标题中。

This should be investigated. If they need cookies -- stream-context-create can help. Or maybe they check referer. But I am almost sure that problem is not in headers.

希望这有帮助。

UPD 您要询问的示例代码。

UPD Sample code you've asked about.

// file to download -- application/octet-stream
$remoteFile = 'http://dev/test/remote/send.php';
// file to download -- application/force-download
$remoteFile = 'http://chtyvo.org.ua/authors/Skriabin_Kuzma/Ya_Pobieda_i_Berlin.rtf.zip';
// file to store
$localFile = 'kuzma.zip';

$fin = fopen($remoteFile, "r");
if (!$fin) {
    die("Unable to open remote file");
}

$fout = fopen($localFile, "w");
if (!$fout) {
    die("Unable to open local file");
}

while (!feof($fin)) {
    $line = fgets($fin, 1024);
    fwrite($fout, $line, 1024);
}

fclose($fout);
fclose($fin);

与您的相同。
