使用c++实现一个tcp socket的服务端程序，实现一下功能：1、在某一个接口内服务端能够接收客户端的请求信息 2、将接收的请求信息传参传出

以下是一个简单的C++ TCP Socket服务端程序，可以实现接收客户端请求信息，并将信息打印出来。

#include <iostream>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <unistd.h>
#include <cstring>

int main()
{
    // 创建socket
    int server_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (server_socket == -1)
    {
        std::cerr << "Failed to create socket!" << std::endl;
        return -1;
    }

    // 绑定地址和端口
    struct sockaddr_in server_addr;
    memset(&server_addr, 0, sizeof(server_addr));
    server_addr.sin_family = AF_INET;
    server_addr.sin_addr.s_addr = htonl(INADDR_ANY);
    server_addr.sin_port = htons(8888);
    if (bind(server_socket, (struct sockaddr*)&server_addr, sizeof(server_addr)) == -1)
    {
        std::cerr << "Failed to bind address and port!" << std::endl;
        close(server_socket);
        return -1;
    }

    // 监听端口
    if (listen(server_socket, 10) == -1)
    {
        std::cerr << "Failed to listen!" << std::endl;
        close(server_socket);
        return -1;
    }

    // 等待客户端连接
    struct sockaddr_in client_addr;
    socklen_t client_addr_len = sizeof(client_addr);
    int client_socket = accept(server_socket, (struct sockaddr*)&client_addr, &client_addr_len);
    if (client_socket == -1)
    {
        std::cerr << "Failed to accept client connection!" << std::endl;
        close(server_socket);
        return -1;
    }

    // 接收客户端请求信息
    char buffer[1024];
    int recv_len = recv(client_socket, buffer, sizeof(buffer), 0);
    if (recv_len > 0)
    {
        buffer[recv_len] = '\0';
        std::cout << "Received message: " << buffer << std::endl;
    }

    // 关闭套接字
    close(client_socket);
    close(server_socket);

    return 0;
}

在该程序中，首先创建了一个TCP Socket，并绑定了地址和端口，然后监听该端口，等待客户端连接。当有客户端连接时，接受客户端请求信息，并将其打印出来。最后关闭客户端和服务端的套接字。
