Question

学习使用thrift，尝试python龙卷风教程。当我开始运行PythonClient.py时，得到错误消息如下：

ERROR:tornado.application:Exception in callback <function null_wrapper at 0x7f38de9bcd70> for <tornado.concurrent.Future object at 0x7f38de9c1110>
Traceback (most recent call last):
  File "/usr/local/python/lib/python2.7/site-packages/tornado/concurrent.py", line 300, in _set_done

    return fn(*args, **kwargs)

    if future.result() is not None:

    yielded = self.gen.throw(*exc_info)
  File "./PythonClient.py", line 58, in communicate
    yield gen.Task(client.ping)
  File "/usr/local/python/lib/python2.7/site-packages/tornado/gen.py", line 870, in run
    value = future.result()

    func(*args, callback=_argument_adapter(set_result), **kwargs)
TypeError: ping() got an unexpected keyword argument 'callback'

教程有什么问题吗？这是源代码： https://git1-us-west.apache.org/repos/asf?p=thrift.git;a=blob;f=tutorial/py.tornado/PythonClient.py;h=005ad3c4d90333946d7c7e90facfd9bc9c43c0d1;hb=HEAD

尝试thrift龙卷风教程得到一个意外的关键字参数'回调'
