节俭：从 tSimpleServer 更改为 TNonblockingServer

Question

我有一个简单的节俭服务器：

  shared_ptr<TProcessor> processor(new MyProcessor(handlerTrace));
  shared_ptr<TServerTransport>  serverTransport(new TServerSocket(port));
  shared_ptr<TTransportFactory> transportFactory(new TBufferedTransportFactory());
  shared_ptr<TProtocolFactory>  protocolFactory(new TBinaryProtocolFactory());

  TSimpleServer server(processor, serverTransport,
               transportFactory, protocolFactory);

并能够与以下线路连接：

   boost::shared_ptr<TSocket> socket(new TSocket("localhost", port));
   boost::shared_ptr<TTransport> transport(new TBufferedTransport(socket));
   boost::shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport));

   MyClient client(protocol);

现在我想将服务器更改为TNonblockingServer. 因此，我将服务器代码更改为以下内容：

  shared_ptr<TServerTransport>  serverTransport(new TServerSocket(port));
  shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory());
  TNonblockingServer server(processor,
                protocolFactory,
                port);

客户端不变。现在服务器抱怨客户端并显示以下错误消息：

Thrift: Mon Aug 19 22:55:43 2013 TNonblockingServer: Serving on port 9990, 1 io threads.
Thrift: Mon Aug 19 22:55:43 2013 TNonblockingServer: using libevent 2.0.16-stable method epoll

我做错了什么？注释？我正在使用 1.0-dev 版本的 thrift 因为只有这个版本支持多路复用..

Answer 1

尝试在您的客户端中使用 TFramedTransport 而不是 TBufferedTransport。看这个例子：http : //wiki.apache.org/thrift/ThriftUsageC%2B%2B

要注意的另一件事是，根据上面的示例，TNonblockingServer 将 ThreadManager 作为参数。
