这是一对实现在两台计算机间传送文件的函数,我没有看到过使用CSocket进行文件传送的代码,希望此代码对你有用.代码中包含两个函数,第一个用于服务器端,第二个用于客户端. 需要说明的是本文提供的方法并不适用于大型文件的传送.下面给出服务器端代码: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(); } 以下是客户端代码 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(); }最好确认服务器端函数在客户端函数之前运行,本文的代码可以方便地添加到工程中,解决服务器/客户模型中的文件传送问题.

如果用tcp/ip协议会很安全,要根据具体的要求来处理!
需要说明的是本文提供的方法并不适用于大型文件的传送.下面给出服务器端代码: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();
}
以下是客户端代码 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();
}最好确认服务器端函数在客户端函数之前运行,本文的代码可以方便地添加到工程中,解决服务器/客户模型中的文件传送问题.
