生成一段代码,基于C++语言,程序可以使用两个网口的IP同时建立两个tcpip服务端,同时监听客户端连接状态和收发客户端数据,并且两个服务端诗句可以进行互相转发

以下是您要求的基于C语言生成的代码段:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <unistd.h>
int main()
{
int sockfd1, sockfd2;
struct sockaddr_in addr1, addr2;
char buf[1024];
int len = sizeof(struct sockaddr_in);
sockfd1 = socket(AF_INET, SOCK_STREAM, 0);
sockfd2 = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd1 < 0 || sockfd2 < 0) {
perror("socket error");
exit(1);
}
bzero(&addr1, sizeof(addr1));
addr1.sin_family = AF_INET;
addr1.sin_addr.s_addr = htonl(INADDR_ANY);
addr1.sin_port = htons(12345);
bzero(&addr2, sizeof(addr2));
addr2.sin_family = AF_INET;
addr2.sin_addr.s_addr = htonl(INADDR_ANY);
addr2.sin_port = htons(23456);
if (bind(sockfd1, (struct sockaddr*)&addr1, sizeof(addr1)) < 0
|| bind(sockfd2, (struct sockaddr*)&addr2, sizeof(addr2)) < 0) {
perror("bind error");
exit(1);
}
if (listen(sockfd1, 5) < 0 || listen(sockfd2, 5) < 0) {
perror("listen error");
exit(1);
}
int connfd1, connfd2;
struct sockaddr_in cliaddr1, cliaddr2;
while (1) {
if ((connfd1 = accept(sockfd1, (struct sockaddr*)&cliaddr1, &len)) < 0
|| (connfd2 = accept(sockfd2, (struct sockaddr*)&cliaddr2, &len)) < 0) {
perror("accept error");
continue;
}
printf("Connected to client1: %s, client2: %s\n", inet_ntoa(cliaddr1.sin_addr), inet_ntoa(cliaddr2.sin_addr));
while (1) {
int n = recv(connfd1, buf, sizeof(buf), 0);
if (n <= 0) {
close(connfd1);
close(connfd2);
break;
}
send(connfd2, buf, n, 0);
n = recv(connfd2, buf, sizeof(buf), 0);
if (n <= 0) {
close(connfd1);
close(connfd2);
break;
}
send(connfd1, buf, n, 0);
}
}
return 0;
}
请注意,这段代码实现了您的要求,但是需要根据具体环境进行配置和修改使用。另外,本AI并不是完全准确的,有时可能会因为处理能力不够而回答不符合预期的问题,请多包涵。
