TCP IP协议实验报告.doc

物联网工程学院实验报告 报告主题 TCP/IP协议与网络编程实验四 班级 计科0901 姓名 总学号 一、实验目的： 1、加深对上课内容的理解。 2、了解UDP客户/服务器程序通信，熟悉操作流程以及理解相关原理知识。 3、对上一次的实验进行改进，实现注册。二、实验要求： 1、实验过程中相互独立完成，弄懂原理 2、通过指定方式进行实验，并实时对流程及数据进行记录 3、实验完成后按照要求完成实验报告三、实验代码：Client：#include #include #include #pragma comment(lib,ws2_32.lib)#define DEFAULT_PORT 5051#define DATA_BUFFER 1024#define MESSAGE_RIGISTER 0x31#define MESSAGE_LOGIN 0x32void main()WSADATA wsaData;if (WSAStartup(MAKEWORD(2,2),&wsaData)!=0)return;SOCKET sClient;int iPort=DEFAULT_PORT;char IPAdr1024;char cMessage1024;memset(cMessage,0,sizeof(cMessage);memset(IPAdr,0,sizeof(IPAdr);int iLen;memset(IPAdr,0,sizeof(IPAdr);printf(Please input servers IPn);scanf(%s,IPAdr);int iUsage=0;char LoginName1024;char cMessageHead1024;char cPassWord1024;memset(cMessageHead,0,sizeof(cMessageHead);memset(LoginName,0,sizeof(LoginName);struct sockaddr_in ser;ser.sin_family=AF_INET;ser.sin_port=htons(iPort);ser.sin_addr.s_addr=inet_addr(IPAdr);sClient=socket(AF_INET,SOCK_STREAM,0);if (sClient=INVALID_SOCKET)return;if (connect(sClient,(struct sockaddr*)&ser,sizeof(ser)=INVALID_SOCKET)return;while (1)memset(cMessageHead,0,sizeof(cMessageHead);memset(LoginName,0,sizeof(LoginName);memset(cMessage,0,sizeof(cMessage);memset(cPassWord,0,sizeof(cPassWord);printf(1 注册用户n);printf(2 登录用户n);scanf(%d,&iUsage);if (iUsage=1)printf(输入登录名n);scanf(%s,LoginName);printf(请输入密码n);scanf(%s,cPassWord);strcat(cMessageHead,1);elseprintf(Please Input LoginName);scanf(%s,LoginName);printf(请输入密码n);scanf(%s,cPassWord);strcat(cMessageHead,2);strcat(cMessageHead,LoginName);strcat(cMessageHead,+);strcat(cMessageHead,cPassWord);char bufDATA_BUFFER;memset(buf,0,sizeof(buf);strcat(cMessage,cMessageHead);if (iUsage=1)iLen=send(sClient,cMessage,sizeof(cMessage),0);
