当 TFramedTransport 打开时，thrift 中的 TNonblockingServer 崩溃

Question

我一直在尝试用 C++ 实现一个 thrift 服务器来与 Python 客户端通信。

这是我的代码：

C++ 服务器：

shared_ptr<ThriftHandler> _handler (new myHandler());
shared_ptr<TProcessor> _processor (new myService(_handler));
shared_ptr<TProtocolFactory> _protocolFactory (new TBinaryProtocolFactory());
shared_ptr<ThreadManager> _threadManager = ThreadManager::newSimpleThreadManager(15);
shared_ptr<PosixThreadFactory> _threadFactory(new PosixThreadFactory());
_threadManager->threadFactory(_threadFactory);
_threadManager->start();

shared_ptr<TNonblockingServer> _server(new TNonblockingServer(_processor, _protocolFactory, 9090 ,_threadManager));;
_server->serve();

Python 客户端代码：

transport = TSocket.TSocket(host, port)
transport = TTransport.TFramedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = MyService.Client(protocol)
transport.open()
log.info("connection success!")

当我启动服务器然后启动客户端时，我得到以下信息：

在客户端（Python）：

./myPythonExec.py
connection success!
socket.error: [Errno 104] Connection reset by peer

在服务器端（c++）：

assertion " 0 " failed

5  0x00007ffff11ed94c in event_base_loop () from /usr/lib/libevent-2.0.so.5

我正在使用 libthrift 0.8.0，并且与 libthrift 0.9.1 具有相同的 pb

在 C++ 上使用 TSimpleServer 并在客户端使用 TBufferedTransport 时，它可以完美运行

抱歉，之前没见过，但看起来是同样的问题： Service Multiplexing using Apache Thrift

简而言之，您必须使用两侧有框架的，或者不使用。

shared_ptr<TTransportFactory> _transportFactory(new TFramedTransportFactory());
shared_ptr<TNonblockingServer> _server(
   new TNonblockingServer(
     _processor, 
     _transportFactory,
     _transportFactory,
     _protocolFactory, 
     _protocolFactory, 
     9090,
     _threadManager));
_server->serve();
