I was just wondering how I can get post and get variables from a website when writing a CGI app.

Generally you look in environment variables for the data but I can't see how purebasic reads Environment variables...

anyone have a real simple CGI example?

There is a usermade library avaiable to use CGI.

http://www.reelmediaproductions.com/pb/

Just type 'CGI' in the search box at the top, and you'll find it.

Thanks, I'll take a look

Is a whole lib really needed? Other languages have a GetEnv or Environ$() call to get the data, after that it's all your own working code and print statemements isn't it?

Does PB not have a way to get an environment var? :roll:

The lib doesn't do much more than that. There are functions to
decode/encode Urls, and one to send the Output back, that's all.

and, no PB doesn't have a way for that, why else should there be a lib for it?

Thanks!

I wonder if there an API call for getting an environment Var?

Sorry, another question.

Would the lib work with Linux too or would I need to find a separate linux lib?

PureBasic will (usually) just include the command data from a lib into
your final exe (if the lib is coded that way). So no, using one command
from a library doesn't always include the whole library code in your exe.

Not as a native command, but you can do it with the API:
viewtopic.php?t=7019

Remember: if PureBasic lacks a command, you can almost always use
an API command (or two) to do the job instead.

(Although this is
only for Windows).

Nope, well...maybe (I dunno if the lib format differs from Win and Linux versions)
Anyway, it`s a definate no if the lib uses any OS API calls or calls to 3rd party shared librarys.

Hi,

This is, more or less, what the StdIn command of the CGI lib does, translated to PB+Win32API:

Code: Select all

bRead.l
hInput = GetStdHandle_(#STD_INPUT_HANDLE)
GetSystemInfo_(sinf.SYSTEM_INFO)
SetConsoleMode_(hInput, #ENABLE_LINE_INPUT|#ENABLE_ECHO_INPUT|#ENABLE_PROCESSED_INPUT)
Buffer = AllocateMemory(0, sinf\dwPageSize)
While ReadFile_(hInput, Buffer, sinf\dwPageSize-1, @bRead, 0) And bRead
  Text$+PeekS(Buffer)
Wend
FreeMemory(0)
Debug Text$ ; there it is

This code is useless if ran as is, in console mode, but it's helpful if you use it as CGI input.

I think it should be easy to do this in Linux (should be easier, so they say

Regards,

CGI

Solved!
