RAC-Hub/WRAC.md

WRACv2.0 Protocol

Uses websocket for connections, and sends binary data only (works in packet-way manner)

Totally inherits all packets of RACv2, except of reading messages

Sending messages

Client sends:

• Byte 0x01
• Message text

Sending authorized messages

Client sends:

• Byte 0x02
• Username
• \n
• Password
• \n
• Message

Server sends:

• nothing if message was sent successfully
• 0x01 if the user does not exists
• 0x02 if the password is incorrect

Registration users

Client sends:

• Byte 0x03
• Username
• \n
• Password

Server sends:

• nothing if user was registered successfully
• 0x01 if the username is already taken

Reading messages

Getting message length

Client sends:

• Byte 0x00

Server sends:

• Size of all messages in ASCII (data_size)

Normal reading

This packet is independent from getting message length packet.

Client sends:

• Byte 0x00
• Byte 0x01

Server sends:

• All messages

Chunked reading

This packet is independent from getting message length packet.

Client sends:

• Byte 0x00
• Byte 0x02
• Size of messages you have in ASCII (last_size)

Server sends:

• All new messages

for example: if you want to read last N bytes, last_size = data_size - N
