如何使用延迟了强制下载的PHP下载文件？ [英] How to download file Using PHP that has delayed force download?

问题描述

我处于一种需要从URL下载文件的情况，使用直接文件URL（例如 https://somedomain.com/some-path/somefile.exe

I am at a situation, where I need to download files from the URL, it is easy with the direct file URLs like https://somedomain.com/some-path/somefile.exe

file_put_contents( $save_file_loc, file_get_contents($url_to_download);

但是当您延迟从实际打印HTML的URL强制下载时该怎么办，以及如何区分这些URL？

But what to do when you have delayed force download from the URL which actually prints HTML and how to differentiate those URL?

示例URL： https： //filehippo.com/download_mozilla-firefox-64/post_download/

编辑：在上述url上，文件下载开始使用JS，就像我测试了阻止JS并进行下载一样不能开始。

On above url the file download starts using JS, as I tested with blocking JS and download did not start.

在此先感谢您的帮助。

推荐答案

1. 使用 file_get_contents


2. 读取URL的html f HTML中的文件。您必须访问该页面并查看源以找到URL。在您的> https://filehippo.com/download_mozilla-firefox-64/post_download/ 在 data-qa-download-url = https://dl5.filehippo.com/367/fb9/ef3863463463b174ae36c8bf09a90145/Firefox_Installer.exe?Expires=1594425587&Signature之间找到= 18ab87cedcf3464363469231db54575665668c4f6& amp; url = https：//filehippo.com/download_mozilla-firefox-64/& amp; Filename = Firefox_Installer.exe"


3. As您可能已经注意到，该页面可能已经预先批准了请求，因此如果主机使用Cookie或其他方法进行检查，则不能保证该页面可以正常工作。


4. 基于上述内容创建一个正则表达式以使用 preg_match


5. 提取URL，然后file_get_contents下载文件的URL。

1. Read the html of the URL using file_get_contents
2. Find the URL of the file within the HTML. You'll have to visit the page and view source to locate the URL. In your example of https://filehippo.com/download_mozilla-firefox-64/post_download/ it's found in between data-qa-download-url="https://dl5.filehippo.com/367/fb9/ef3863463463b174ae36c8bf09a90145/Firefox_Installer.exe?Expires=1594425587&Signature=18ab87cedcf3464363469231db54575665668c4f6&url=https://filehippo.com/download_mozilla-firefox-64/&Filename=Firefox_Installer.exe"
3. As you may have noticed, the page may have pre-approved the request so it's not guaranteed to work if the host has checks using cookies or other methods.
4. Create a regex based on the above to extract the URL using preg_match
5. Then file_get_contents the URL of the file to download it.
