如何将C/C++套接字发送和接收函数封装在一个类中？

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

class Socket {
private:
    int sockfd;
    struct sockaddr_in serverAddr;

public:
    Socket() {
        sockfd = socket(AF_INET, SOCK_STREAM, 0);
        if (sockfd == -1) {
            std::cerr << "Failed to create socket." << std::endl;
            exit(EXIT_FAILURE);
        }

        memset(&serverAddr, 0, sizeof(serverAddr));
        serverAddr.sin_family = AF_INET;
        serverAddr.sin_port = htons(8080);
        serverAddr.sin_addr.s_addr = inet_addr("127.0.0.1");
    }

    ~Socket() {
        close(sockfd);
    }

    bool connectToServer() {
        if (connect(sockfd, (struct sockaddr*)&serverAddr, sizeof(serverAddr)) == -1) {
            std::cerr << "Failed to connect to server." << std::endl;
            return false;
        }
        return true;
    }

    bool sendMsg(const char* msg) {
        if (send(sockfd, msg, strlen(msg), 0) == -1) {
            std::cerr << "Failed to send message." << std::endl;
            return false;
        }
        return true;
    }

    bool receiveMsg(char* buffer, int bufferSize) {
        int bytesRead = recv(sockfd, buffer, bufferSize - 1, 0);
        if (bytesRead == -1) {
            std::cerr << "Failed to receive message." << std::endl;
            return false;
        }
        buffer[bytesRead] = '\0';
        return true;
    }
};

int main() {
    Socket socket;
    if (socket.connectToServer()) {
        socket.sendMsg("Hello, server!");
        
        char buffer[1024];
        if (socket.receiveMsg(buffer, sizeof(buffer))) {
            std::cout << "Received message from server: " << buffer << std::endl;
        }
    }

    return 0;
}
