Question

我正在运行官方节俭py：tornado demo，在客户关闭运输后引发异常。

示例：https://github.com/apache/thrift/tree/master/tutorial/py.tornado

Starting the server...

calculate(1, Work(comment=None, num1=1, num2=0, op=4))
calculate(1, Work(comment=None, num1=15, num2=10, op=2))

TTransportException: Stream is closed

有没有办法避免这个错误消息或如何捕获它？

Answer 1

很多原因会导致StreamClosedError。

检查节俭服务器端，可能会引发异常。
经过测试，我发现节俭THttpServer无法提供Tornado客户端流。
并且，当我将龙卷风版本从4.4.3升级到4.5时，StreamClosedError消失了。

客户端Thrift版本：0.10.0

龙卷风版：4.5

客户端Python版本：3.5.2

系统版本：Ubuntu 16.04

与龙卷风示例服务器的thrift引发异常
