How can I use webseed when download files with hashinfo?

[hz0324]

I just knew the concept of webseed and feel like it will solve our problem : downloading starts too late (about 1 minute)

Right now, we have parsed 1000+ files and get their hashinfo stored in our database. Users can search the filename to get the hashinfo, and then download the file using the hashinfo in a web app just like instant.io.
(when user click download, we will call the server host the files to start seeding the target file).

This works fine overall, but very slow. Usually, the downloading starts in about 1 minute.

Since we know where the files are, I think we can add some information, such as webseed url, to facilitate the downloading. But I can not find anything about "using webseed with hashinfo". Is this possible?

Thanks.

From the docs at https://webtorrent.io/docs

torrent.addWebSeed(url)

Add a web seed to the torrent swarm. For more information on BitTorrent web seeds, see BEP19.

In the browser, web seed servers must have proper CORS (Cross-origin resource sharing) headers so that data can be fetched across domain.

The url argument is the web seed URL.

 

You could also create a magnet link using the infohash and url like this

let infoHash = 'infohash here'
let webSeed = 'webseed url here'
let magnetLink = `magnet:?xt=urn:btih:${infoHash}&ws=${webSeed}` // you also need to add trackers for torrenting in browser

Thank you very much, I just knew that magnet link can be created with infohash and webseed.
It is really helpful, thank you.
Have a good day
