Linux + socket多线程并发服务端+ 聊天室
对于在Linux上开发网络聊天室,使用Socket编程是一个常见的方法。Socket编程允许应用程序在网络上进行通信。在Linux下,可以使用C语言的Socket库来实现网络聊天室。
以下是一个简单的示例代码,演示了如何在Linux上使用Socket编程创建一个基本的网络聊天室:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <arpa/inet.h>
#include <sys/socket.h>
#define MAX_CLIENTS 10
#define BUFFER_SIZE 1024
int main() {
int server_socket, client_socket;
struct sockaddr_in server_address, client_address;
socklen_t client_address_length;
char buffer[BUFFER_SIZE];
// 创建服务器套接字
server_socket = socket(AF_INET, SOCK_STREAM, 0);
if (server_socket == -1) {
perror("Failed to create socket");
exit(EXIT_FAILURE);
}
// 设置服务器地址
server_address.sin_family = AF_INET;
server_address.sin_addr.s_addr = INADDR_ANY;
server_address.sin_port = htons(8888);
// 绑定服务器套接字到指定地址和端口
if (bind(server_socket, (struct sockaddr *)&server_address, sizeof(server_address)) < 0) {
perror("Failed to bind socket");
exit(EXIT_FAILURE);
}
// 监听传入的连接请求
if (listen(server_socket, MAX_CLIENTS) < 0) {
perror("Failed to listen");
exit(EXIT_FAILURE);
}
printf("Server started. Waiting for connections...\n");
while (1) {
// 接受客户端连接
client_address_length = sizeof(client_address);
client_socket = accept(server_socket, (struct sockaddr *)&client_address, &client_address_length);
if (client_socket < 0) {
perror("Failed to accept connection");
exit(EXIT_FAILURE);
}
printf("New connection accepted\n");
// 处理客户端消息
while (1) {
memset(buffer, 0, BUFFER_SIZE);
ssize_t bytes_received = recv(client_socket, buffer, BUFFER_SIZE, 0);
if (bytes_received < 0) {
perror("Failed to receive data from client");
exit(EXIT_FAILURE);
} else if (bytes_received == 0) {
printf("Client disconnected\n");
break;
}
printf("Received message: %s", buffer);
// 回复客户端消息
if (send(client_socket, buffer, strlen(buffer), 0) < 0) {
perror("Failed to send data to client");
exit(EXIT_FAILURE);
}
}
// 关闭客户端套接字
close(client_socket);
}
// 关闭服务器套接字
close(server_socket);
return 0;
}
```
这段代码创建了一个基本的服务器,通过监听指定的端口来接受客户端的连接。一旦有客户端连接成功,服务器将接收客户端发送的消息,并将其回显给客户端。当客户端断开连接时,服务器将关闭与该客户端的连接。
需要注意的是,这只是一个基本的示例,缺乏错误处理和安全性考虑。在实际开发中,你可能需要添加更多的功能和验证逻辑以满足你的需求。
