基于Boost的同步TCP通信

1：客户端

　　

 #include <iostream>
 #include <boost/asio.hpp>

 using namespace boost;
 using namespace std;
 using boost::asio::ip::tcp;

 int main()
 {
         try
         {
                 typedef tcp::endpoint endpoint_type;
                 typedef tcp::socket     socket_type;
                 typedef asio::ip::address       address_type;

                 cout<<"client start."<<endl;
                 asio::io_service io;

                 socket_type sock(io);
                 endpoint_type ep(address_type::from_string("127.0.0.1"),);

                 sock.connect(ep);
                 cout<<sock.available()<<endl;

                 vector<char> str(sock.available()+,);
                 sock.receive(asio::buffer(str));

                 cout<<"receive from"<<sock.remote_endpoint().address();
                 cout<<&str[]<<endl;

         }
         catch(std::exception& e)
         {
                 cout<<e.what()<<endl;
         }
         return ;
 }

2：服务端

　　

 #include <iostream>
 #include <boost/asio.hpp>

 using namespace boost;
 using namespace std;
 using boost::asio::ip::tcp;

 int main()
 {
         try
         {
                 typedef tcp::acceptor acceptor_type;
                 typedef tcp::endpoint endpoint_type;
                 typedef tcp::socket     socket_type;

                 cout<<"server start."<<endl;
                 asio::io_service io;

                 acceptor_type acceptor(io,endpoint_type(tcp::v4(),));
                 cout<<acceptor.local_endpoint().address()<<endl;

                 for(;;)
                 {
                         socket_type sock(io);
                         acceptor.accept(sock);

                         cout<<"client:";
                         cout<<sock.remote_endpoint().address()<<endl;

                         sock.send(asio::buffer("hello asio"));
                 }
         }
         catch(std::exception& e)
         {
                 cout<<e.what()<<endl;
         }
         return ;
 }
