Can the project run directly? What I need is to get the metadata according to infohash

Hi,

What version are you using? Are you trying to download just the metadata file, or the entire torrent? What exact error are you getting?

I just fixed a minor bug that broke magnet link downloads in the latest snapshot. #196

I will merge it once the CI passes.

At present, I only have infohash and hostname. port 。 Now I want to get the corresponding metadata. Which method do you need?

Hi, I think you'll need to write a bit of java code to do this.

First, create a torrent context with a Magnet URI. Some examples on how to do this:
https://github.com/atomashpolskiy/bt/blob/master/examples/src/main/java/peertracker/Main.java

bt/bt-tests/src/main/java/bt/it/fixture/LeecherPeer.java

Line 58 in 8fb4276

MagnetUri magnetUri = MagnetUri.torrentId(torrent.getTorrentId()).tracker(announceKey.getTrackerUrl()).buildUri();

If the hostname/port you have are for a tracker, then you'll need to add it to the magnet URI. If the hostname/port you have are of a peer, the easiest way to bootstrap this peer is with a mock tracker. See: https://github.com/atomashpolskiy/bt/blob/master/examples/src/main/java/yourip/mock/MockTracker.java

When you build a torrent context, there is a callback for when the torrent is fetched:

bt/bt-core/src/main/java/bt/TorrentClientBuilder.java

Line 202 in 8fb4276

public B afterTorrentFetched(Consumer<Torrent> torrentConsumer) {

You can write a callback method that writes the torrent to disk, and then stops the torrent.

@atomashpolskiy - perhaps this might be a good feature to have? When metadata is downloaded from a magnet link, have an option to persist it to disk.

Create a MagnetUri object with the builder (both peer and tracker addresses can be supplied) https://github.com/atomashpolskiy/bt/blob/master/bt-core/src/main/java/bt/magnet/MagnetUri.java#L108 Feed this uri to the client being constructed https://github.com/atomashpolskiy/bt/blob/master/bt-core/src/main/java/bt/TorrentClientBuilder.java#L139 Set the callback to be invoked when the metadata has been fetched (can shutdown from inside the callback) https://github.com/atomashpolskiy/bt/blob/master/bt-core/src/main/java/bt/TorrentClientBuilder.java#L202 CLI client is a good example of how to construct clients overall https://github.com/atomashpolskiy/bt/blob/master/bt-cli/src/main/java/bt/cli/CliClient.java
