Hi all,
I'm now learning how to use fpWeb. But for some reasons, I don't want to use
Lazarus. Instead, I want to write the program using plain text editor or
console text editor (like vim, nano, etc), in case I need to do it remotely.
It's now just a simple Hello World program, so it must be simple enough to
write the program as a single file without Lazarus. However, I failed. There
must be something stupid that I forgot to write but I don't know what that is.
So here's my code: program HelloWeb;
{$MODE OBJFPC}{$H+}{$J-}
uses Classes, HTTPDefs, fpHTTP, fpCGI, fpWeb;
type THelloModule = class(TFPWebModule) procedure HelloReq(Sender: TObject;
ARequest: TRequest; AResponse: TResponse; var Handled:
Boolean); end;
var HelloModule: THelloModule;
procedure THelloModule.HelloReq(Sender: TObject; ARequest: TRequest;
AResponse: TResponse; var Handled: Boolean);begin
AResponse.ContentType := 'text/html;charset=utf-8'; AResponse.Content :=
'<html><body>Hello World!</body></html>'; Handled := true;end;
begin HelloModule := THelloModule.Create(nil); HelloModule.ActionVar := 'm';
HelloModule.OnRequest := @HelloModule.HelloReq;
RegisterHTTPModule('THelloModule',THelloModule,true);
Application.Title := 'Hello World'; Application.Initialize;
Application.Run;end.
It was compiled fine without any errors using -XXs -CX -O3 parameters. But when
the executable is deployed and then accessed from the browser, it returns 500
internal server error. I don't know what to do as I saw nothing is wrong.
That's the first problem. The second one is a question. I'd like to use fpWeb
components in plain procedural way, without using the TApplication
infrastructure, especially for simple CGI apps/services. Is it possible? Any
advices?
I'm using a Linux Ubuntu 14.04 machine with Apache web server. I believe the
problem has nothing to do with the OS nor the web server because my plain
Pascal CGI (without using fpWeb) is running just fine.
Any hints to solve the problem is really appreciated.
Thank you.
Regards,
–Mr Bee
