无法编译boost :: asio :: basic_datagram_socket <boost::asio::ip::udp> :: basic_datagram_socket（）

Question

我正在尝试制作一个合适的udpServer类，该类将成为udpServerBoost的父级。 （udpServer未实现atm）

而且由于我尝试更改类构造函数以让它自己创建io_service，所以在编译src时出现错误

我已经用g ++编译了boost库，并且可以正常工作。 所以我知道问题并非来自此:(

这就是我的来源！ 感谢阅读^^

祝你今天愉快

这是我的udpServerBoost.cpp

UdpServerBoost::UdpServerBoost()
{
    boost::asio::io_service io_service;
    socket_ = udp::socket(&io_service, udp::endpoint(udp::v4(), 1300));

    memset(&recv_buffer_, 0, 2048);
    clientList_ = std::vector<ClientBoost>();
    startReceive();
    io_service.run();
}

和.hpp

class UdpServerBoost
{
  public:
    UdpServerBoost();
    ~UdpServerBoost() {};

  private:
    void startReceive();

    void handleReceive(const boost::system::error_code &error,
                       std::size_t bytes_transferred);

    void handleSend(boost::shared_ptr<std::string> /*message*/,
                    const boost::system::error_code & /*error*/,
                    std::size_t /*bytes_transferred*/);

    ClientBoost getClient();

    void treatMessage(std::string mess);
    void sendToClient(ClientBoost client, std::string mess);

    std::vector<ClientBoost> clientList_;
    udp::socket socket_;
    udp::endpoint remote_endpoint_;
    boost::array<char, 2048> recv_buffer_;
};

Answer 1

您正在默认构造套接字。 那是不允许的。 您至少必须提供对其执行程序（io_service）的引用。

尝试这样的事情：

class UdpServerBoost
{
  UdpServerBoost();

  boost::asio::io_service my_io_service_;
  udp::socket my_socket_;
};

UdpServerBoost::UdpServerBoost()
: my_io_service_()
, my_socket_(my_io_service_)
{
}
