如何获得客户端IP地址与C ++在thrift [英] How to get client IP Address with C++ in thrift

问题描述

我现在在C ++中实现基于节点的（0.4.0）服务，遇到一个问题：

有一种方法可以获得客户端的IP地址从一个服务方法实现？

解决方案

$ b <在TNonblockingServer中，当TProcessor :: process（）被调用时，TProtocol.transport是一个TMemoryBuffer，所以客户端ip地址是不可能的。

但是我们可以扩展类TServerEventHandler，当客户端要调用处理器时，调用方法TServerEventHandler :: processContext（）。

  static boost :: thread_specific_ptr< std :: string> thrift_client_ip; //线程特定
类MyServerEventHandler：public TServerEventHandler 
 {
 virtual void processContext（void * serverContext，boost :: shared_ptr< TTransport> transport）
 {
 TSocket * sock = static_cast< TSocket *>（transport.get（））; 
 
 if（sock）
 {
 //thrift_client_ip.reset(new string（sock-> getPeerAddress（）））; // 0.9.2，重用TNonblockingServer :: TConnection返回脏地址，参见https://issues.apache.org/jira/browse/THRIFT-3270 
 sock-> getCachedAddress（）; // use this api instead 
} 
} 
}; 
 
 //创建非阻塞服务器
 TNonblockingServer服务器（processor，protocolFactory，port，threadManager）; 
 boost :: shared_ptr< MyServerEventHandler> eventHandler（new MyServerEventHandler（））; 
 server.setServerEventHandler（eventHandler）; 
  

I am implementing a thrift-based (0.4.0) service in C++ at the moment and encountered a question:

Is there a way to get the client's IP address from inside a service method implementation? I am using a TNonblockingServer.

Thanks in advance!

解决方案

In TNonblockingServer, When TProcessor::process() is called the TProtocol.transport is a TMemoryBuffer, so aquiring client ip address is impossible.

But We can extend class TServerEventHandler, method TServerEventHandler::processContext() is called when a client is about to call the processor.

static boost::thread_specific_ptr<std::string> thrift_client_ip; // thread specific
class MyServerEventHandler : public TServerEventHandler
{
    virtual void processContext(void* serverContext, boost::shared_ptr<TTransport> transport)
    {
        TSocket *sock = static_cast<TSocket *>(transport.get());

        if (sock)
        {
            //thrift_client_ip.reset(new string(sock->getPeerAddress())); // 0.9.2, reused TNonblockingServer::TConnection return dirty address, see https://issues.apache.org/jira/browse/THRIFT-3270
            sock->getCachedAddress(); // use this api instead
        }
    }
};

// create nonblocking server
TNonblockingServer server(processor, protocolFactory, port, threadManager);
boost::shared_ptr<MyServerEventHandler> eventHandler(new MyServerEventHandler());
server.setServerEventHandler(eventHandler);
