A web server coded in C.

Provides an API and a web access.

• libevent-dev
• libconfig-dev
• libmap (https://github.com/padawin/map-structure-implementation)

In config.conf, change the values to match your environment.

Compile it:

make
make install

./server

To use the web part, you'll need a web folder and its path must be in the web_root variable in the config.cfg.

For example if you have in your web folder a test.html file, you can serve it: http://localhost:port/web/test.html

To use the API part, you'll need to call http://localhost:port/api

The api uses .so modules. The modules must be stored in the directory defined in configuration key 'api_modules_path'.

A module must have this include:

#include "webserver/module.h"

This provides the signatures for the functions:

* char *get_call(void);
* char *post_call(void);
* char *get_call(void);
* char *post_call(void);
* char *head_call(void);
* char *put_call(void);
* char *delete_call(void);
* char *options_call(void);
* char *trace_call(void);
* char *connect_call(void);
* char *patch_call(void);
* char *get_call(void);
* char *post_call(void);
* char *get_call(void);
* char *post_call(void);
* char *head_call(void);
* char *put_call(void);
* char *delete_call(void);
* char *options_call(void);
* char *trace_call(void);
* char *connect_call(void);
* char *patch_call(void);

Which are called depending on the HTTP request method. The functions' return values are the response body.

To compile a module, use the server's Makefile:

make /path/to/your/module.so

The module's source must be in /path/to/your/module.c.

To use a module, it must be registered in the configuration file in the key 'api_modules' and 'api_modules_number'. For example, if you have two modules "foo.so" and "bar.so", your configuration file must look like:

api_modules_number = 2;
api_modules: ("foo", "bar");

And then restart the server and call http://localhost:port/api/%modulename%

#include <webserver/module.h>
#include <map.h>
#include <stdlib.h>

char *get_call(map *params)
{
	char *foo;

	if ((foo = map_get_entry("foo", params)) != NULL) {
		return foo;
	}

	return (char *) "foo";
}
