I require tutorials to develop remote control usbcamera on
webserver..
When i type my ip , the leds.html is opening and able to control it. But
cant understand how it is working.Kindly provide any pdf or tutorial for
entire webserver programming
Thanks a lot in advance
Hi Arjun,
You can make web application in any language or script which can PRINT text
to screen (stdout). Your program just have to print HTML on screen - when
executed as CGI program, web server will redirect stdout to remote user -
output will go to user's browser instead of screen. For example if you are
using C language, basic program looks like this:
#include <stdio.h>
int main()
{
// This is http header and is mandatory. MUST be terminated with two
linefeed characters: \n\n
printf("Content-type: text/html\n\n");
// this is HTML content
printf("<html><body>\n");
printf("<p>Hello world!</p>\n");
printf("</body></html>\n");
// return 0 means "success"
return 0;
}
This is C example, but you can make CGI program in any language in the same
way - just print HTTP header and HTML to screen.
Here is good-old book about CGI programming:
http://oreilly.com/openbook/cgi/ch01_01.html
For receiving reqests from user (for example: data entered into form) you
need to decode environment variables which are set by web server. This is
not trivial, so you need to use some CGI library which does this job.
If you are using C/C++ language, I will suggest you CppWeb library which is
light-weight and portable - it compiles on ARM (and other systems) and has
many usefull functions for CGI/Web programming.
You can download CppWeb library here:
