客户端和服务器端交互时,必须使用Socket中提供得网络流,不能使用自己创建的流对象 当我们创建客户端Socket对象时,就会使用TCP协议与服务器建立连接通路,若服务器没有启动,就会抛出异常。 服务器类:ServerSocket类 TCP通信的服务器端:接受客户端的请求,读取客户端发送的数据,给客户端回写数据,两次IO流,一直处于等待状...

编写一个程序,使用udp通信,client是10.21.1.142, server是10.21.1.229,port是3000. client发送end能使得程序结束。 客户端: #include <stdio.h> #include <sys/socket.h> #include <sys/types.h> #include <string.h> #include <netinet/in.h>
创建socket: int server_fd = socket(AF_INET, SOCK_STREAM, 0); if (server_fd == -1) { perror("socket failed"); exit(EXIT_FAILURE); } 其中,AF_INET表示IPv4,SOCK_STREAM表示TCP协议。 准备地址结构体: struct sockaddr_in server_addr; ...
