DHT

DHT implements the bittorrent DHT protocol in Go. Now it includes:

• BEP-3 (part)
• BEP-5
• BEP-9
• BEP-10

It contains two modes, the standard mode and the crawling mode. The standard mode follows the BEPs, and you can use it as a standard dht server. The crawling mode aims to spide as more medata info as possiple. It doesn't follow the standard BEPs protocol.

bthub.io is a BT search engine based on the crawling mode.

)

func main() {
    downloader := dht.NewWire()
    go func() {
        // once we got the request result
        for resp := range downloader.Response() {
            fmt.Println(resp.InfoHash, resp.MetadataInfo)
        }
    }()
    go downloader.Run()

    config := dht.NewCrawlConfig()
    config.OnAnnouncePeer = func(infoHash, ip string, port int) {
        // request to download the metadata info
        downloader.Request([]byte(infoHash), ip, port)
    }
    d := dht.New(config)

    d.Run()
}
