我正在尝试Apache Thrift使用python 3.4,Thrift似乎有支持,因为它有lib.linux-x86_64-3.4
在build
目录下。但我一直在收到此错误消息
File "/home/qunzi/Downloads/thrift-0.9.2/lib/py/build/lib.linux-x86_64-3.4/thrift/transport/TTransport.py", line 163, in write
self.__wbuf.write(buf)
TypeError: string argument expected, got 'bytes'
有人知道发生了什么,可能还有解决方案吗?
以下是相关代码
socket = TSocket.TSocket('localhost', 9090)
transport = TTransport.TBufferedTransport(socket)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = Algo.Client(protocol)
transport.open()
ping_req = PingRequest()
ping_resp = client.ping(ping_req)
整个追溯:
File "py3client.py", line 36, in <module>
ping_resp = client.ping(ping_req)
File "/home/qunzi/Projects/test/sample_Test/py3.4_thrift/ib/Algo.py", line 66, in ping
self.send_ping(request)
File "/home/qunzi/Projects/test/sample_Test/py3.4_thrift/ib/Algo.py", line 70, in send_ping
self._oprot.writeMessageBegin('ping', TMessageType.CALL, self._seqid)
File "/home/qunzi/Downloads/thrift-0.9.2/lib/py/build/lib.linux-x86_64-3.4/thrift/protocol/TBinaryProtocol.py", line 46, in writeMessageBegin
self.writeI32(TBinaryProtocol.VERSION_1 | type)
File "/home/qunzi/Downloads/thrift-0.9.2/lib/py/build/lib.linux-x86_64-3.4/thrift/protocol/TBinaryProtocol.py", line 111, in writeI32
self.trans.write(buff)
File "/home/qunzi/Downloads/thrift-0.9.2/lib/py/build/lib.linux-x86_64-3.4/thrift/transport/TTransport.py", line 163, in write
self.__wbuf.write(buf)
TypeError: string argument expected, got 'bytes'
答案 0 :(得分:1)
虽然这个问题已经死了,但看起来我有一个答案:)
当前的thrift python生成器(从0.9.3开始)生成特定于python2的代码。至少我只是换了齿轮和代码给了我同样的错误,现在就像一个魅力。
错误是由(隐式)处理库中的所有类似字符串的对象(如字节对象)引起的。但是,在Python3中,StringIO类需要面向字符串的字符串(str
),而那些面向字节的字符串会导致异常。
应该向Thrift跟踪器提交一个错误,现在他/她应该使用Python2。
