這是一對(duì)實(shí)現(xiàn)在兩臺(tái)計(jì)算機(jī)間傳送文件的函數(shù),我沒(méi)有看到過(guò)使用CSocket進(jìn)行文件傳送的代碼,希望此代碼對(duì)你有用.代碼中包含兩個(gè)函數(shù),第一個(gè)用于服務(wù)器端,第二個(gè)用于客戶(hù)端.
需要說(shuō)明的是本文提供的方法并不適用于大型文件的傳送.
下面給出服務(wù)器端代碼:
void SendFile()
{
#define PORT 34000 /// Select any free port you wish
AfxSocketInit(NULL);
CSocket sockSrvr;
sockSrvr.Create(PORT); // Creates our server socket
sockSrvr.Listen(); // Start listening for the client at PORT
CSocket sockRecv;
sockSrvr.Accept(sockRecv); // Use another CSocket to accept the connection
CFile myFile;
myFile.Open("C:\\ANYFILE.EXE", CFile::modeRead | CFile::typeBinary);
int myFileLength = myFile.GetLength(); // Going to send the correct File Size
sockRecv.Send(&myFileLength, 4); // 4 bytes long
byte* data = new byte[myFileLength];
myFile.Read(data, myFileLength);
sockRecv.Send(data, myFileLength); //Send the whole thing now
myFile.Close();
delete data;
sockRecv.Close();
}
以下是客戶(hù)端代碼
void GetFile()
{
#define PORT 34000 /// Select any free port you wish
AfxSocketInit(NULL);
CSocket sockClient;
sockClient.Create();
// "127.0.0.1" is the IP to your server, same port
sockClient.Connect("127.0.0.1", PORT);
int dataLength;
sockClient.Receive(&dataLength, 4); //Now we get the File Size first
byte* data = new byte[dataLength];
sockClient.Receive(data, dataLength); //Get the whole thing
CFile destFile("C:\\temp\\ANYFILE.EXE",
CFile::modeCreate | CFile::modeWrite | CFile::typeBinary);
destFile.Write(data, dataLength); // Write it
destFile.Close();
delete data;
sockClient.Close();
