from portal.generic.plugin_interfaces import IPluginBlock

class MyBlockPlugIn(Plugin):
    """ PLUGIN EXAMPLE

        the pluginblock "myblock"
    """

    implements(IPluginBlock)

        self.plugin_guid = '53D22AB9-EDB6-4388-8A9A-D752A81D7040'

    def return_string(self, tagname, *args):
        from urllib.request import urlopen
        f = urlopen("http://www.google.com")
        encoding = f.headers['content-type'].split('charset=')[-1]
        s = str(f.read(), encoding)
        f.close()
        return s
