Apache Thrift Python-Java“连接被拒绝”

Question

我最近尝试使用Thrift将Python连接到Java。我已经在Python（PyPy）上编写了服务器。我还写了一个有效的参考客户。然后，我编写了一个Java客户端，该客户端仅产生“拒绝连接”异常。这怎么了 （最近我还发现了一个封闭的问题，该问题的特征是https://issues.apache.org/jira/browse/THRIFT-1888）PS。使用过的Thrift 0.9版本，PyPy 2.0 beta 2，Java 1.7.0_11节俭namespace java com.testnamespace python testservice TestPing {   void ping()} Python服务器代码class TestPingHandler:  def ping(self):    passhandler = TestPingHandler()processor = TestPing.Processor(handler)transport = TSocket.TServerSocket(port=9091)tfactory = TTransport.TBufferedTransportFactory()pfactory = TBinaryProtocol.TBinaryProtocolFactory()server = TServer.TThreadedServer(processor, transport, tfactory, pfactory)print 'Starting the server...' server.serve()print 'done.' Java客户端代码TTransport transport;transport = new TSocket("localhost", 9091);transport.open();TProtocol protocol = new TBinaryProtocol(transport);client = new TestPing.Client(protocol);client.ping();参考Python客户端代码transport = TSocket.TSocket('localhost', 9091)transport = TTransport.TBufferedTransport(transport)protocol = TBinaryProtocol.TBinaryProtocol(transport)client = TestPing.Client(protocol)transport.open()client.ping()transport.close()

Answer 1

我遇到过同样的问题。用ip替换“ localhost”来修复它。

原因是：Python使用TCPV6，而Java使用TCP。

Python： transport = TSocket.TServerSocket(host="127.0.0.1", port = 9091)

Java的： transport = new TSocket("127.0.0.1", 9091);

Answer 2

transport = new TSocket("localhost", 9091);

TProtocol protocol = new TBinaryProtocol(transport);

transport.open();

This should work...
