VCMFC下实现简单的socket发送接收文件.doc

最简单的发送接收文件(VC6.0下编译通过):

Server:
#include<afx.h>
#include<winsock2.h>
#pragmacomment(lib,"WS2_32.lib")
intmain()
{
WSADATAdata;
intm;
WORDw=MAKEWORD(2,0);
::WSAStartup(w,&data);
SOCKETs,s1;
s=::socket(AF_INET,SOCK_STREAM,0);//IPPROTO_TCP);
sockaddr_inaddr2,addr;
chartext[100]={0};
intn=sizeof(addr2);
addr.sin_family=AF_INET;
addr.sin_port=htons(75);
addr.sin_addr.S_un.S_addr=INADDR_ANY;
::bind(s,(sockaddr*)&addr,sizeof(addr));
::listen(s,5);
printf("服务器已经启动\r\n");
s1=::accept(s,(sockaddr*)&addr2,&n);
if(s1!=NULL){
printf("%s已经连接上\r\n",inet_ntoa(addr2.sin_addr));
::recv(s1,text,100,0);
//CFilefile((LPSTR)text,CFile::modeReadWrite);
if(text!=0){
MessageBox(NULL,text,"xiaoxi",MB_OK);
CFilefile1(text,CFile::modeCreate|CFile::modeReadWrite);
if(file1!=NULL){
do{
m=::recv(s1,text,100,0);
file1.Write(text,100);
}while(m==100);

}
file1.Close();
}
}
::closesocket(s);
::closesocket(s1);
::WSACleanup();
::WSACleanup();
return1;
}

Client:
#include<afx.h>
#include<winsock2.h>
#pragmacomment(lib,"WS2_32.lib")
intmain(){
WSADATAdata;
WORDw=MAKEWORD(2,0);
::WSAStartup(w,&data);
SOCKETs;
chartext[100];
charfilename[100];
printf("输入文件名:\n");
gets(filename);
CFilefile(filename,CFile::modeReadWrite);
CStringstr;
s=::socket(AF_INET,SOCK_STREAM,0);
sockaddr_inaddr;

addr.sin_family=AF_INET;
addr.sin_port=htons(75);
addr.sin_addr.S_un.S_addr=inet_addr("服务器IP");//本机程序服务器IP为你的机子IP或127.0.0.1;
printf("客户端已经启动\r\n");
intm=::connect(s,(sockaddr*)&addr,sizeof(addr));
if(m!=-1)
{
intm;
str=file.GetFileName();
MessageBox(NULL,str,"xiaoxi",MB_OK);
::send(s,str,str.GetLength(),0);
file.Read(text,100);
do{
::send(s,text,100,0);
m=file.Read(text,100);
printf("%d\n",m);
}while(m);

}
file.Close();
::closesocket(s);
::WSACleanup();
return1;
}
