为什么数据不传输

我正在尝试设计一个客户端服务器程序，其中双方{server，客户端}都可以与async_connect通信。 这是我的服务器程序代码：

std::string GetMessage()
{
std::string user("User");
user += client;
client++;
return user;
}
class TcpConnection
: public boost::enable_shared_from_this<TcpConnection>
{
private:
boost::asio::ip::tcp::socket socket1;
std::string message;

TcpConnection(boost::asio::io_service &io_service) :
socket1(io_service)
{
}
void Writehandler(const boost::system::error_code &errorCode, size_t size)
{
if (!errorCode)
{
Read();
}
std::cout << errorCode.message() << std::endl;
}
public:
typedef boost::shared_ptr<TcpConnection> pointer;
static pointer Create(boost::asio::io_service &io_service)
{
return pointer(new TcpConnection(io_service));
}
boost::asio::ip::tcp::socket &socket()
{
return socket1;
}
void Start()
{
message = GetMessage();
boost::asio::async_write(socket(), boost::asio::buffer(message),
boost::bind(&TcpConnection::Writehandler, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
void Read()
{
std::array<char, 65> messages{};
auto self(shared_from_this());
boost::asio::async_read(socket(),
boost::asio::buffer(messages),
[this, self](boost::system::error_code ec, std::size_t /*length*/) {
if (!ec) {
Read();
} else {
std::cout << ec.message() << std::endl;
exit(1);
}
});
}
};
class Server
{
private:
boost::asio::ip::tcp::acceptor acceptor;

public:
Server(boost::asio::io_service &io_service, unsigned short int port)
:
acceptor(io_service, boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), port))
{
startAccept();
}
void startAccept()
{
TcpConnection::pointer newConnection = TcpConnection::Create(acceptor.get_io_service());
acceptor.async_accept(newConnection->socket(),
boost::bind(&Server::Handler, this, newConnection, boost::asio::placeholders::error
));
}
void Handler(TcpConnection::pointer &newConnection, const boost::system::error_code &errorCode)
{
if (!errorCode)
newConnection->Start();
startAccept();
}
};

}

这是我的客户端代码：

class Client
: public boost::enable_shared_from_this<Client>
{
private:
boost::asio::ip::tcp::socket socket1;
std::string port;
public:
Client(boost::asio::io_service &io_service, std::string port)
: port(std::move(port)),
socket1(io_service)
{
start();
}
void handler(const boost::system::error_code &errorCode, size_t size)
{
}
boost::asio::ip::tcp::socket &socket()
{
return socket1;
}
void start()
{
try
{
boost::asio::ip::tcp::resolver resolver(socket1.get_io_service());
boost::asio::ip::tcp::resolver::query query(boost::asio::ip::tcp::v4(), port);
boost::asio::ip::tcp::resolver::iterator endpoint = resolver.resolve(query);
std::cout << exception.what() << std::endl;
}
}
void read()
{
std::array<char, 64> messages{};
boost::asio::async_read(socket(),
boost::asio::buffer(messages.data(), messages.size()),
[this](boost::system::error_code ec, std::size_t /*length*/)
{
if (!ec)
{
read();
} else
{
socket().close();
}
});
}
void write()
{
std::string message{};
getline(std::cin, message, 'n');
boost::asio::async_write(socket(),
boost::asio::buffer(message),
[this](boost::system::error_code ec, std::size_t /*length*/)
{
if (!ec)
{
write();
} else
{
socket().close();
}
});
}
};

代码没有错误。 但是当我连接两个数据时没有注入。
