with my version of OmniHTTPd, in the cgi-bin, theres a couple of programs, which in the readme, says they're written in C++.

the program generates an image of the counter, with the current number of hits. i attached the readme, incase you dont know what i mean

how do you write CGI-Executables in C++?

the person said he has the full-source on his page, but the page was down.

also, my other question

Just write "Content-type: text/html\n\n" to STANDARD OUTPUT and then your HTML data.

Code:

#include <stdio.h> 
#include <stdlib.h>

main() {
		char *chRM;
		char *chQS;

		chRM = getenv("HTTP_USER_AGENT");
		
		//check for NULL or we'll get at error with printf
		if (chRM == NULL) {
			chRM = "NONE";
		}

		chQS = getenv("QUERY_STRING");

		if (chQS == NULL) {
			chQS = "NONE";
		}

        printf("Content-type: text/html\n\n");
        printf("<html>\n");
		printf("<head><title>CGI Test</title></head>\n");
		printf("<body>\n");
        printf("<p>Hello World!\n");
		printf("<br><b>HTTP_USER_AGENT:</b> ");
		printf(chRM);
		printf("<br><b>QUERY_STRING:</b> ");
		printf(chQS);
		printf("</p>\n");
		printf("</body>\n");
        printf("</html>\n");
		return 0;
}

thanks man

This is quite old so it's not the greatest code around - I can see some obvious optimisations it can have (not to mention some things which are evil enough to demand a rewrite), but I don't really need it anymore so I'm sure you can manage it nicely

So Ked, no jumping down my throat about any of it, k?

**parksie** · Dec 26th, 2001, 06:29 PM

And the header file...

**kedaman** · Dec 26th, 2001, 06:38 PM

spreading evil code around again parksie?

where's the headerfile`?

*prepares to write a load of comments* j/k

**nabeels786** · Dec 26th, 2001, 07:52 PM

yah, u forgot the header file

so, i just add it to my project and since its a class, i just declare and use it?

cool-o.

optimizations: err i have no clue. but that's ok

im horrible at C++

how would i process a parameter that is passed? lets say

cgiexetext.exe?URL=http://www.hotmail.com

just check for it through the void main(int argc, char *argv[]) way? like retrive it then parse it?

thx guys

Sorry I couldn't get onto VBW last night very well, and I thought it had attached it but obviously not (you might notice that this was one of my last posts yesterday).

Anyway, I didn't forget - see my post above

Code:

CLibCGI CGI;
string keyword;

CGI.Setup();

keyword = CGI.GetValueFromName("keyword");

I admit, something like this would have been better:

Code:

CLibCGI CGI;

keyword = CGI["keyword"];

But remember, I wrote this in Feb 2000 so it's getting VERY old now

**nabeels786** · Dec 27th, 2001, 11:10 AM

heh. cool thanks. so i would do

Code:

CLibCGI CGI;
string URL;

CGI.Setup();

URL = CGI.GetValueFromName("URL");

and then from there i can do what i want/need?

thanks for the help!

**nabeels786** · Dec 27th, 2001, 11:41 AM

ok i tried it like you said, and it gives an error, and it wants to send an error report to microsoft. (running win xp)

but, when i take out the CGILib stuff, it works fine, it outputs.

Code:

//#include "libcgi.cpp"
#include "libcgi.h"

void main(int argc, char *argv[]){
	CLibCGI cgi;
	string URL;

	cgi.Setup();

	printf("Content-type: text/html\n\n");
	printf("<html><head><title>Forwarding...</title></head>\n\n");


	URL = cgi.GetValueFromName("site");


	if(URL.length == 0){
		printf("<body>");
		printf("No URL was specified<br>\n\n");
		printf("</body></html>");

	}
	else{
		printf("<script>window.location = %c%s%c;</script>\n\n",39,URL,39);
		printf("</body></html>");
	}

	
}

thanks

Don't include the .cpp file - you compile that separately and link it in.

**nabeels786** · Dec 28th, 2001, 11:51 AM

ohhh ok

thanks
