It currently works for the GTK3 version of Turtle Blocks and # only from the GNOME desktop. # USAGE: Download this file into the gnome_plugin directory; make sure the # filename is fb_plugin.py (Mediawiki capitalizes the first letter of files). # When you launch TA from the GNOME desktop by running turtleblocks.py # you should see a new menu, Facebook, which allows you to upload your # project. Please report any problems to rgs and walter. import pycurl import sys import urlparse from gi.repository import Gtk from gi.repository import WebKit from plugin import Plugin from util.menubuilder import MenuBuilder from gettext import gettext as _ class FbUploader(): UPLOAD_URL = "https://graph.facebook.com/me/photos?access_token=%s" def __init__(self, image_path, access_token): self._image_path = image_path self._access_token = access_token def doit(self): c = pycurl.Curl() c.setopt(c.POST, 1) c.setopt(c.URL, self._get_url()) c.setopt(c.HTTPPOST, self._get_params(c)) c.perform() print c.getinfo(c.HTTP_CODE) def _get_url(self): return self.UPLOAD_URL % (self._access_token) def _get_params(self, c): params = [] params.append(('source', (c.FORM_FILE, self._image_path))) return params class Fb_plugin(Plugin): APP_ID = "172917389475707" REDIRECT_URI = "http://www.sugarlabs.org" def __init__(self, parent): self._access_token = "" self._auth_win = None def get_menu(self): menu = Gtk.Menu() MenuBuilder.make_menu_item(menu, _('Wall post'), self._post_menu_cb) upload_menu = MenuBuilder.make_sub_menu(menu, _('Facebook')) return upload_menu def set_tw(self, turtleart_window): self.tw = turtleart_window def enabled(self): return True def _post_menu_cb(self, widget): if self._access_token == "": self._grab_fb_app_token() return self._post_to_fb() def _grab_fb_app_token(self): url = self._get_auth_url() w = Gtk.Window() w.move(200, 200) w.set_size_request(800, 400) wkv = WebKit.WebView() wkv.load_uri(url) wkv.grab_focus() wkv.connect('navigation-policy-decision-requested', self._nav_policy_cb) w.add(wkv) w.show_all() self._auth_win = w def _get_auth_url(self): url = "http://www.facebook.com/dialog/oauth?client_id=%s" % (self.APP_ID) url += "&redirect_uri=%s" % (self.REDIRECT_URI) url += "&response_type=token&scope=publish_stream" return url def _nav_policy_cb(self, view, frame, req, action, param): uri = req.get_uri() if uri: url_o = urlparse.urlparse(uri) params = urlparse.parse_qs(url_o.fragment) if params.has_key('access_token'): self._access_token = params['access_token'][0] self._auth_win.hide() self._post_to_fb() def _post_to_fb(self): ta_file, image_file = self.tw.save_for_upload("ta fb") uploader = FbUploader(image_file, self._access_token) uploader.doit()
