我有一个问题,是一个beginer,我要尽量使该帖子给Facebook,我用的是tornado exampletornado-facebook-sdk一个简单的异步程序,这里是代码:不能获得Facebook的龙卷风连接

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) 

和我得到这个错误:

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

,因为我想了解这个例子中获得令牌,然后使用例如:

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

要在我的脸书的墙上写点东西,我用the synchronous library做了,但可惜这是封锁!

UPDATE:仍然获取和错误:

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") 

,并得到这个错误:

[E 121009 14:28:47 web:1108] Uncaught exception GET/(::1)

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

,当我去给Facebook,我看到它是我使用的Valide关键,我甚至使用生成的令牌(这里是a变量),并粘贴到Api调试,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

self加到print_callback

def print_callback(self, data): 
    print data 
    ioloop.stop() 
    graph.get_object('/facebook', callback=print_callback) 
+0

所以这是着名的“明确比实施更好”;) 谢谢 –
