Hello

Im trying to execute commands on server side. Here is my server based on other example from forum:

#!/usr/bin/rdmd

import std.stdio;
import std.socket;
import std.algorithm;
import std.conv;

void main() {
    Socket server = new TcpSocket();
    server.setOption(SocketOptionLevel.SOCKET, SocketOption.REUSEADDR, true);
    server.bind(new InternetAddress(8080));
    server.listen(1);


	Socket client = server.accept();

    while(true) {


        char[1024] buffer = 0;
        auto received = client.receive(buffer);

        writefln("The client said:\n%s", buffer[0.. received]);

        enum header =
            "HTTP/1.0 200 OK\nContent-Type: text/html; charset=utf-8\n\n";

        string response = header ~ "Hello World!\n";
        client.send(response);
	

	if(to!string(buffer) == "exit")
	{
		
		break;
	}
   }

    client.shutdown(SocketShutdown.BOTH);
    client.close();

}

When i send "exit" nothing is happening. How it should be done to make it working?

You are comparing whole buffer to "exit"

I changed my condition to:

if(to!string(buffer[0..received]) == "exit")
	{
		
		break;
	}


But it still dint help.

The client probably sends a newline; i.e. buffer[0 .. received] is "exit\n".

Or more likely it's "exit\r\n".

I changed condition to:

if(to!string(buffer[0..received]) == "exit\n")
	{
		
		break;
	}

and now it is working. Thank you all for help.

You shouldn't need that to!string by the way. I believe that will work just comparing the buffer directly.

Converting to string is more important when you are storing a copy than just comparing it.
