I had to remove my original one so I reuploaded this with much better quality.
(If you want it sound like previous one, try setting quality to 240p)
Yeah, I know that video sucks compared to original but no can do :(

Todo

1. Add more unit tests
2. Update documentation
3. Add more parsers

link-preview's Issues

YouTube no longer works

Message: Client error response [status code] 410 [reason phrase] Gone [url] http://gdata.youtube.com/feeds/api/videos/zCbfWGgp9qs?v=2&alt=jsonc

Small improvement for readme

The utf8_decode( ) function willl make sure that for example Russian characters get displayed properly. This is almost crucial when dealing with content that needs to be previewed coming from anywhere in the world.

A sentence like: "Священная война (The Sacred War) - Alexandrov Red Army Choir" would otherwise show up as "СвÑ�Ñ�еннаÑ� война (The Sacred War) - Alexandrov Red Army Choir".

Upgrade Guzzle

Hi Kasp3r,

Can you upgrade Guzzle to 7x?

This is why it won't work on Laravel as it depends on a later version, Laravel 8x requires Guzzle ^7.0.1.

"guzzlehttp/guzzle": "^7.0.1"

Thanks

Derek

getImage() returning shorthand protocol instead of http/https

$filename = tempnam('/tmp', '');
file_put_contents($filename . '.jpg', file_get_contents($preview->getUrl()));

$preview->getUrl() returns //s.ytimg.com/yts/img/yt_1200-vfl4C3T0K.png which causes file_get_contents($preview->getUrl()) to fail.

Concatenating http: to getUrl() works.

Redirects/requests with cookies

I noticed today that some links are not parsed correctly. Eg. Akamai specifies a cookie a shows a redirect ('Location' header) and then the next page expects to see the cookie.

Now I assume that link-preview doesn't store/use cookies so it's unable to visit the page.

Given that Facebook and others do this just fine, I assume there are no legal/whatever requirements and this can be done.

Would you do it yourself or would you prefer a PR?

Whitespaces

Some websites include many whitespaces in their tags. For example see the title tag of https://www.fressnapf.de/p/penthouse-arthur.

Maybe apply a trim on all values? I did no pull request because there is another one open and maybe you have a better solution / more generic way or just want to include all whitespaces. So, just an issue and freedom to decide 💃

How to avoid blocked port

Hi,
Is the plugin validating the blocked ports? For example, www.dinamalar.com is working, suppose if the user enters https://dinamalar.com then it will crash as the port 443 is not open on that website. How to fix this issue?
