See SocketServerBase::Message::fin_rsv_opcode. For instance inside the onmessage lamda: message->fin_rsv_opcode
. If I remember correctly, the codes are the same as when sending to the client: https://github.com/eidheim/Simple-WebSocket-Server/blob/master/server_ws.hpp#L224
from simple-websocket-server.
Yes, fin_rsv_opcode is a way to check if the data is binary or not. https://github.com/eidheim/Simple-WebSocket-Server/blob/master/server_ws.hpp#L117 subclasses std::istream, so you can use std::istream::read (Message::read). You can also use the Message::string() method as it does not matter if its return is binary or text, the only difference is how you would use it. For instance, you would not try to output binary data to a terminal.

Thanks.
Do you mean we can use fin_rsv_opcode to test if the message contains binary data? I guess my problem is that I know for sure the message will contain binary data, but I want to get the data. I check the source (https://github.com/eidheim/Simple-WebSocket-Server/blob/master/server_ws.hpp#L117) and found the class Message doesn't seem to provide a way to access the data (string() will just return the data parsed as string, right?). I guess maybe I need to modify class Message a bit to access the data? I am new to C++, so my question may sound stupid :)

I see. Thank you so much for the help. I will test it after work.
