<p>There's a web services I want to call in my application, I can use it with importing the WSDL or by just use "HTTP GET" with the URL and parameters, so I prefer the later because it's simple thing.</p>

<p>I know I can use indy idhttp.get, to do the job, but this is very simple thing and I don't want to add complex indy code to my application.</p>

<p><strong>UPDATE</strong>: sorry if I was not clear, I meant by "not to add complex indy code", that I don't want add indy components for just this simple task, and prefer more lighter way for that.</p>

Calling a RESTful web service using Indy is pretty straight forward.
Add IdHTTP to your uses clause.  Remember that IdHTTP needs the "HTTP://" prefix on your URLs.
```
```
function GetURLAsString(const aURL: string): string;
var
  lHTTP: TIdHTTP;
begin
  lHTTP := TIdHTTP.Create;
  try
    Result := lHTTP.Get(aURL);
  finally
    lHTTP.Free;
  end;
end;
```
```
