如何在C编程中发送文件和文件名？ [英] How to send a file along with filename in C programming?

问题描述

我在tcp / ip中从客户端向服务器发送文件，在接收端，我很难编码文件名。而不是这个我希望收到与客户端相同的文件名。如何在c编程中实现这一目标？我可以提供一些示例代码供进一步参考。

Hi,

I am sending a file from client to server in tcp/ip, in the receiving end, i am hard coding the file-name. Instead of this i would like to receive the same file name as it is in client. How can this be achieved in c programming? Can i have some sample code for further reference.

推荐答案

如果你不能像PIEBALDconsult建议的那样使用FTP或HTTP（甚至是Kermit）你可能需要派生你的自己的'迷你协议' - 即，



1）Header =发送一个固定长度的文件名和文件中的字节数，也可能是一个校验和

2）数据=以字节形式发送文件

3）响应=收到并确认后收到响应（＃bytes，checksum）



（但这一切都在重新发明轮子，当然）



'g'

If you cant use FTP or HTTP as PIEBALDconsult suggests (or even Kermit) you'd likely have to derive your own 'mini protocol' - ie,

1) Header = send a fixed length filename and the number of bytes in the file, maybe a checksum as well
2) Data = send the file as bytes
3) Response = receive a response back when its been received and acknowledged (# bytes, checksum)

(but all this is re-inventing the wheel, surely)

'g'
