我有一个问题,我是初学者,我尝试制作一个简单的异步程序来发布到 facebook,我使用tornado 示例tornado-facebook-sdk,这里是代码:

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来获取token,然后使用例子:

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

为了在我的 facebook 墙上写点东西,我用同步库做到了,但遗憾的是这被阻塞了!

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 Facebook 时,我看到它是我正在使用的验证密钥,我什至使用生成的令牌(这里是a变量),并将其粘贴到 Api Debug,我得到了一切正常:

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

添加selfprint_callback.

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