无法获得Facebook-Tornado连接

Question

我有一个问题，我是一个初学者，我尝试制作一个简单的异步程序发布到Facebook，我使用龙卷风示例和龙卷风-Facebook-SDK，这是代码：

class MainHandler(BaseHandler, tornado.auth.FacebookGraphMixin):
    @tornado.web.authenticated
    @tornado.web.asynchronous
    def get(self):
        self.facebook_request("/me/home", self.print_callback, access_token=self.current_user["access_token"])
        a = self.current_user["access_token"]
        #print a
    def print_callback(data):
        print data
        ioloop.stop()
        graph.get_object('/facebook', callback=print_callback)

我收到此错误：

TypeError: print_callback() takes exactly 1 argument (2 given)

因为我想了解此示例以获取令牌，然后使用示例：

def callback(response):
    # ...
graph.put_object('me', 'feed', message="Maoe!!", callback=callback)

为了在我的Facebook墙上写一些东西，我用同步库做了，但可悲的是，这是阻塞的！

更新：仍然得到和错误：

class MainHandler(BaseHandler, tornado.auth.FacebookGraphMixin):
    @tornado.web.authenticated
    @tornado.web.asynchronous
    def get(self):
        self.facebook_request("/me/home", self.print_callback, access_token=self.current_user["access_token"])
        a = self.current_user["access_token"]
        print a
    def print_callback(self, data):
        graph.post_wall(self, "heloooooooo")

并得到此错误：

    raise GraphAPIError(data)
GraphAPIError: (#200) This API call requires a valid app_id.

当我去Facebook时，我看到它是我正在使用的有效密钥，我什至使用生成的令牌（这里是a变量），并将其粘贴到Api调试中，我得到一切正常：

 Valid : True
 Origin : Web
 Scopes : create_note photo_upload publish_actions publish_stream read_stream share_item status_update video_upload

将self添加到print_callback 。

def print_callback(self, data):
    print data
    ioloop.stop()
    graph.get_object('/facebook', callback=print_callback)
