如何从在 Laravel 中重定向的 url 下载文件? [英] How to download file from url that redirects in Laravel?

问题描述

我在从 summernote 下载内嵌图像时遇到问题从 GMAIL 复制图像时.

Gmail 返回这样的链接:

https://mail.google.com/mail/u/0?ui=2&ik=d3d2b70b46&attid=0.2&permmsgid=msg-f:1651797278805284123&th=16ec5cdf9c&view=fimg;sz=s0-l75-ft&attbid=ANGjdJ9_MfHq-YioubDagNZ5h216toG9gPg11wV4SkG0Q73urVHcSFnjGKdM4b6b7BfEir0xUp3f4A2ULo9A2srvL7svlpHpZ3RampLdPhlpHpHpZ3RampLvLvlpHpLz&L&L&L

像这样重定向到动态 URL:

<预> <代码> https://gm1.ggpht.com/puicw0cCLZ4huu-Pwk3VHJ8R-wdB2bIHYi4v4F8yUxSnt0UpQQ5LArR9szM5JIqNHPo7JBUbFIf0nsh4JKakewl91Zl08pnNcxmMah6tAFNFWOFaiVJDhxA4RGHvyFxP90HR2DLKHL1MAz8TC9zY8qEliO3vxCv-KqNfq0WBvkFY2fb2GvAWtSTNhksmSHV8_pAKVRyT5aGnbmlH1SWRk_HmTfH27aoslF1P_Lc0245h2nwuhBQ6WpoMgE8eij_Z0QWrHqJWHB0xhAIFAdtIb5E

我使用这个file_get_contents($link)失败了，因为我无法获得图片的原始链接

如何在 Laravel 控制器中获取图片的原始链接?

注意:这些只是虚拟网址.

我的问题与此类似:如何从 url 下载文件重定向?但我似乎无法找到它的 Laravel 版本.

解决方案

我们需要启用重定向.

$opts = array('http' =>大批('follow_location' =>1、));$context = stream_context_create($opts);$result = file_get_contents('http://example.com/', false, $context);

默认情况下，根据 docs 文档，重定向是已启用，但我出于教育目的在上面明确启用了它.

I'm having a problem with downloading an inline image from summernote when the image is copied from GMAIL.

The Gmail returns link like this:

https://mail.google.com/mail/u/0?ui=2&ik=d3d2b70b46&attid=0.2&permmsgid=msg-f:1651797278805284123&th=16ec5cdf9c25551b&view=fimg&sz=s0-l75-ft&attbid=ANGjdJ9_MfHq-YioubDagNZ5h216toG9gPg11wV4SkG0Q73urVHcSFnjGKdM4b6b7BfEir0xUp3f4A2ULo9A2srvLz4hlMdP727bJYHpSyL92kesSl3W74lRZFs9HBU&disp=emb&rv71

Which redirects to dynamic URL like this:

https://gm1.ggpht.com/puicw0cCLZ4huu-Pwk3VHJ8R-wdB2bIHYi4v4F8yUxSnt0UpQQ5LArR9szM5JIqNHPo7JBUbFIf0nsh4JKakewl91Zl08pnNcxmMah6tAFNFWOFaiVJDhxA4RGHvyFxP90HR2DLKHL1MAz8TC9zY8qEliO3vxCv-KqNfq0WBvkFY2fb2GvAWtSTNhksmSHV8_pAKVRyT5aGnbmlH1SWRk_HmTfH27aoslF1P_Lc0245h2nwuhBQ6WpoMgE8eij_Z0QWrHqJWHB0xhAIFAdtIb5E

I failed using this file_get_contents($link) because I can't get the original link of the image

How can I get the original link of the image in the Laravel Controller?

Note: These are just dummy URLs.

My question is similar to this: How to download file from url that redirects? But I can't seem to find a Laravel version of that.

解决方案

We need to enable redirection.

$opts = array('http' =>
    array(
        'follow_location' => 1,
    )
);
$context = stream_context_create($opts);
$result = file_get_contents('http://example.com/', false, $context);

By default, according to the docs docs, redirection is enabled, however I explicitly enabled it above for educational purposes.
