篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了TCP通信聊天服务端和客户端(C/C++语言开发)附完整源码相关的知识,希望对你有一定的参考价值。
距离上次学Python写的Python实现简单聊天室已经过去好久了,现在学c++又写了一遍,其实过程差不多,无非是语法的变化,目前仅实现最简单的一对一的通信,然后改就是了,接下来应该是多线程了,话不多说直接贴上源码;
一、服务端源码
#include <stdio.h>
#include <arpa/inet.h>
// #include <sys/types.h>
// #include <sys/socket.h>
#include <netinet/in.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
int main()
//1、socket
int sfd = socket(AF_INET, SOCK_STREAM, 0);
if (sfd == -1)
perror("socket");
exit(-1);
// 2、bind ip and port
struct sockaddr_in saddr; //专用socket地址
saddr.sin_family = PF_INET;//协议族,ipv4的AF_INET也可以
// inet_pton(AF_INET, "192.168.193.128", saddr.sin_addr.s_addr);
saddr.sin_addr.s_addr = INADDR_ANY; // 监听所有外网接口, INADDR_ANY = 0
saddr.sin_port = htons(9999);//绑定的服务端口9999
int ret = bind(sfd, (struct sockaddr *)&saddr, sizeof(saddr));
if (ret == -1)
perror("bind");
exit(-1);
// 3、listen
ret = listen(sfd, 128);
if (ret == -1)
perror("listen");
exit(-1);
// 4、accept
struct sockaddr_in client_addr;
socklen_t addrlen = sizeof(client_addr);//客户端socket地址的大小
int newfd = accept(sfd, (struct sockaddr *)&client_addr, &addrlen);
if (newfd == -1)
perror("accept");
exit(-1);
// output connect message
char clientIP[16];
inet_ntop(AF_INET, &client_addr.sin_addr.s_addr, clientIP, sizeof(clientIP));
unsigned short clientPort = ntohs(client_addr.sin_port);
printf("client %s:%d is connect. \\n", clientIP, clientPort);
// 5、recv and send
char recvBuf[1024] = 0;
while(1)
memset(recvBuf, 0, sizeof(recvBuf)); //clear buffer
int num = read(newfd, recvBuf, sizeof(recvBuf));//read datas
if (num == -1)
perror("read");
exit(-1);
else if (num > 0)
printf("client message : %s\\n", recvBuf);
else if (num == 0)
printf("server close.");
break;
char respondData[] = "Your message is receive,thanks!";
write(newfd, respondData, sizeof(respondData));
// 6、close
close(sfd);
close(newfd);
return 0;
二、客户端源码
#include <stdio.h>
#include <arpa/inet.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
int main()
// 1.创建套接字
int fd = socket(AF_INET, SOCK_STREAM, 0);
if(fd == -1)
perror("socket");
exit(-1);
// 2.连接服务器端
struct sockaddr_in serveraddr;
serveraddr.sin_family = AF_INET;
inet_pton(AF_INET, "192.168.223.128", &serveraddr.sin_addr.s_addr);
serveraddr.sin_port = htons(9999);
int ret = connect(fd, (struct sockaddr *)&serveraddr, sizeof(serveraddr));
if(ret == -1)
perror("connect");
exit(-1);
// 3. 通信
char recvBuf[1024] = 0;
char client_data[1024];// 从键盘输入,给客户端发送数据
while(1)
memset(client_data, 0, sizeof(client_data));
printf("请输入发送数据:");
scanf("%s", client_data);
write(fd, client_data, strlen(client_data));
sleep(1);
int ret = read(fd, recvBuf, sizeof(recvBuf));
if(ret == -1)
perror("read");
exit(-1);
else if(ret > 0)
printf("server message : %s\\n", recvBuf);
else if(ret == 0)
printf("server closed...\\n");
break;
// 关闭连接
close(fd);
return 0;
三、效果
服务端:
客户端:
