Ask a network file transfer

jucengge

Now there are several clients, one server, and each client has some files. You need to enter the IP address on the server to display these files after connecting to the client, and select the required files to upload to the server. What do you need? Ideas to do? Thank you

Should be reversed,
1 The client connects to the server
2 The client sends the file list to the server
3. The server displays the file class table
4. Pick the file to upload
5. The server requests files from the client
6 The client sends the file requested by the server to the server
7 Perform step 5 until there are no required files

In fact, the server can actively connect to the client, as long as the communication protocol is customized. After the client receives the corresponding protocol package, it will reply its own file list information.

A simple Winsock will do, but at the application layer, you may need to set some protocols.

I ’m doing it too, but it ’s just a client-to-client file transfer, ready to be forwarded by the server, but it seems very troublesome

I am also doing it, but it is the file transfer between the client and the client, and I am going to use the server to forward it, but it seems very troublesome

you should use P2P model

Drift Bottle is an unmanned, serverless peer-to-peer communication tool.

It uses UDP high-speed transmission and verification after receiving, so the data transmission speed is extremely fast.

It combines the advantages of QQ, Diandian, and video calls. It is very suitable for friends who like to watch movies and chat online.

The more people involved, the more resources (videos, software) available

Operation: Click "Login", specify a file to use

Teaching: VC programming such as video, voice, sniffing, etc. QQ: 415159914.

As an example, the drift bottle contains the following:

1. The creation of irregular forms.
2. Custom form class.
3. Video capture
4. MPEG4 video compression and decoding
5. Voice compression and decoding.
6. Color progress bar
7. UDP large file transmission
8. Intranet penetration technology (NAT)

Sniffing programming:

1. Packet capture
2. Data packet format analysis.
3.WINPCAP fully learns.
4. Data package construction
5.Understand all network protocols such as ARP, TCP, UDP, HDCP, etc.
