A simple Delphi CGI application.

Posted on 2001-09-13

Could someone do me a walk-through description of creating a Delphi CGI application that simply accepts a variable (person's name) and creates a HTML page that says hello to that person?

My server-side scripting is okay, and I get how it works, but don't know how to create it in Delphi.  (Just got some web space on an NT server.)

I prefer to use ISAPI, it's better than CGI and have more benefits more than the CGI

here's a good site for ISAPI Tutorials, it fully made by delphi

and here's some link for CGI

Hi John,

1.From File-New select 'Web server app'.
2.From the next menu select 'CGI standalone exe'.
3.You will see a tree WebModule1-Actions. Select 'Actions', right-click on it and select 'Add Item' from the popup menu. WebActionItem1 appears.
4.Select that item and change its 'Default' property to True - this means that that item will be executed on every request.
5.Create an OnAction event handler for that item like the following:

procedure TWebModule1.WebModule1WebActionItem1Action(Sender: TObject;
  Request: TWebRequest; Response: TWebResponse; var Handled: Boolean);
  UserName : string;
  UserName := Request.QueryFields.Values['name'];
  Response.Content := '<HTML><BODY>Hello ' + UserName + '</BODY></HTML>';
  Handled := True;

6.Build the CGI app as 'MyCGI.exe' for example and place it on the server.

7. Calling your app from a html page:
Your html link to call that CGI should look like:

<A HREF="">Click me</A>

Here 'name' is a query field and 'John' is its value, which value will be passed to your app.

Another way:
If you want to use a html form for calling your app, then 1.Change the WebActionItem1 'MethodType' property from mtAny to mtPost. (optional)
2.In the code above use 'ContentFields' instead of 'QueryFields'.
3.Call the app from a html page like:

<INPUT TYPE=text NAME="name"  VALUE="">
<INPUT TYPE=submit VALUE="Submit">
