Comment ajouter une fonction de classe pour obtenir les pairs terminés dans un torrent?

Question

J'ai créé un script qui génère des informations sur un fichier torrent!Mais je manque de créer des graines et des pairs affichant une fonction!Quelqu'un m'a dit qu'ils sont dans le domaine terminé défini dans le torrent.S'il vous plaît mes codes de fonction de classe à partir desquels j'affiche les informations générées à l'aide d'un bencode.php qui sort des données et de ce script, nommé torrent.php convertit sur une forme lisible!

Answer 1

Little late but the class you say to have created comes from:

https://github.com/torrage/Torrage

It's original purpose was not intended to retrieve that kind of data.

A class that gets you seeds and peers for torrent inclusive the rest of the data see:

https://github.com/adriengibrat/torrent-rw

Answer 2

That information's not stored in the .torrent file. It's highly dynamic data, which can change every microsecond on a 'busy' torrent. The server's not going to build a custom .torrent file with up-to-the-minute statistics every time someone downloads it.

Think about it for a second. You download a .torrent file on Monday, but only look at it next Friday. The stats are now a week old and stale.

You can, however, take the tracker information in the .torrent and query those trackers for the stats.
