这是完整代码，下面的是绑定ip和端口的部分
setsockopt(listenfd, SOL_SOCKET, SO_REUSEADDR, &opt, sizeof(opt));
memset(&servaddr, 0, sizeof(struct sockaddr_in));
port = atoi(argv[1]);
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons(port);
servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
port的值是预定义的8080；
INADDR_ANY意思是本机ip，你也可以用数字，不过要符合标准追问你这是socket的服务器部分，上面的绑定IP是0.0.0.0IP地址，就是全接收，那客户端那边怎么从外部填入客户端地址？
