SFML网络C ++客户端无法连接

Question

目前我正在尝试学习SFML网络，但我遇到了客户端问题（我认为）。

#include <iostream>
#include <SFML/Network.hpp>
#include <SFML/System.hpp>

int main()
{
    sf::TcpSocket sock;
    sf::Packet backpack;
    sf::Thread Thread;
    std::cout <<"Attempting to connect to server" << std::endl;
    sf::Socket::Status status = sock.connect("127.0.0.1", 25568);
    if (status != sf::Socket::Done){
    std::cout << "Could Not Connect to server" << std::endl;
    } else {
        std::cout << "Connected to server" << std::endl;
    }
    backpack << 9;
    std::cout << "Sending data" << std::endl;
    sock.send(backpack);
    std::cout << "Sent the data" << std::endl;


    std::cout << "Client task completed" << std::endl;
    return 0;
}

这是服务器代码

#include <iostream>
#include <SFML/Network.hpp>

int main()
{
    std::cout << "Server Has started" << std::endl;
    sf::TcpSocket peer;
    sf::TcpListener ear;
    sf::Packet backpack;

    if (ear.listen(25568) != sf::Socket::Done){
        std::cout << "Listerner failed to be setup, another program may be using that port." << std::endl;


    } else {
        std::cout << "Server is ready" << std::endl;

    }
    if (ear.accept(peer) != sf::Socket::Done){
        std::cout << "Client refused connection" << std::endl;

    } else {
        std::cout << "Client connection Accepted" << std::endl;

    }
    peer.receive(backpack);
    std::cout << "Data recieved" << std::endl;
    int num;
    backpack >> num;
    std::cout << num << std::endl;

    std::cout << "hello world" << std::endl;

    return 0;
}

运行服务器和客户端时（按任意顺序）客户端将在消息后输出任何内容＆＃34;尝试连接到服务器＆＃34;出现，并且服务器在消息＆＃34;服务器准备就绪后输出任何内容＆＃34;请帮助=）我一直坚持这个问题。
