Get text from site with fetchRemote

[holuzs]

I want to get text from a page with fetchRemote. So, when a player enter a command with a code, the fetchRemote call a site with 2 GET request. How can I get a simply text from the site?

function newCommand(player, cmd, code) 
	fetchRemote('http://domain.tld/index.php?get&code='..code, function(data, error) 
		if (error) then return print(error); end
     
	end);
end 
addCommandHandler('cmd', newCommand);

If fetch was success, the 'error' equals 0. So, 'if (error) then' always true.

You need to terminate the function and print the error, if 'error' not equals or greater then 0.

 

Hungarian:

A visszakapott error változó mindig vesz fel értéket, ha minden rendben volt, akkor nullát.

Mivel 'if (error) then' mindig igaz lesz, ezért minden esetben kilépsz a funckcióból a returnal.

 

Correct:

-- SERVER SIDE

function newCommand(player, cmd, code) 
    fetchRemote('http://domain.tld/index.php?get&code='..code, function(data, error) 
        if (error ~= 0) then return print(error); end
      
        print("Result: " .. data);
    end);
end 
addCommandHandler('cmd', newCommand);
