Chrome Extension Torrent from pirateBay to Transmission - 2017-04

This extension aims to put a context menu to chrome witch allow the user to add a torrent from magnet link (as in the PirateBay "download this torrent" button link) directly into transmission via the transmission-daemon RPC.

Pre-Requisite

• Client : Google chrome
• Server : transmission-daemon (https://doc.ubuntu-fr.org/transmission)

Install

• Goto chrome://extensions
• Check "Developer mode"
• Click on load non-packaged extension
• Put the url of the transmission-daemon server in script.js (in the var "urlTransmission") and on the manifest.json file under "permissions"
• Select this folder

Reference

• Google Chrome extension reference for context menus : https://developer.chrome.com/extensions/samples#search:contextmenus
• Transmission Web RPC reference : https://trac.transmissionbt.com/browser/trunk/extras/rpc-spec.txt
• Pirate Bay link example : magnet:?xt=urn:btih:71dac39824e6dae52a77a6a127e3593f59a4a9e8&dn=The.100.S04E08.HDTV.x264-KILLERS%5Bettv%5D&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Fzer0day.ch%3A1337&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Fexodus.desync.com%3A6969

Note

• The default url for transmission web RPC is http://hostIp:hostPort/transmission/rpc so you have to put the right url in the script.js
• To get the method right you have to stringify a json var containing arguments, ie :

params = {
       "arguments": {
           "fields": [
               "id", 
               "name"
           ]
       }, 
       "method": "torrent-get"
    };

... and send JSON.stringify(params) as request body.

Todo

• Problem with CORS (cross origin check inside chrome) prevents to send a post request from the javascript to the transmission server ! It's a ongooing bug : https://trac.transmissionbt.com/ticket/5463 -> ok you just have to put the transmission server address in the manifest under "permissions". This brings another todo :
• Set the url of the server in extension options.
• React directly to a click on a "magnet" link
• Add notification on success or error instead of alert
• Only show the context menu if the link is a torrent
