Lazarus: Set User-Agent in TFPHttpClient

The TFPHttpClient provides the AddHeader function, which allows you to add any headers you want to your request.

AddHeader takes two parameters, the name of the header and the value. To set the user agent for example to Mozilla/5.0, it would be this:

AddHeader('User-Agent', 'Mozilla/5.0');

Altogether, the call can be implemented like that:

hc := TFPHttpClient.Create(Nil);
try
  hc.AddHeader('User-Agent', 'Mozilla/5.0');
  html := hc.Get(url);
finally
  hc.Free;
end;

Of course, instead of Mozilla/5.0, you can also pass any other string of your desire.
