libevent可以快速实现一个http服务器evhttp

从张宴的http://blog.s135.com/httpsqs/

看到了libevent可以快速实现一个http服务器。后来又从搜搜evhttp的例子。拿ab测了测，速度还不错。比Nginx模块稍慢。

 

 

#include <stdlib.h>

#include <stdio.h>

#include <time.h>

 

#include <err.h>

#include <event.h>

#include <evhttp.h>

 

void now_handler(struct evhttp_request *req, void *arg)

{

        struct evbuffer *buf;

        buf = evbuffer_new();

 

        if (buf == NULL)

            err(1, "failed to create response buffer");

 

        evbuffer_add_printf(buf, "zlj");

        evhttp_send_reply(req, HTTP_OK, "OK", buf);

}

 

int main(int argc, char **argv)

{

    struct evhttp *httpd;

 

    event_init();

    httpd = evhttp_start("0.0.0.0", 6006);

    if ( httpd == NULL )

    {

        fprintf(stderr, "Start server error: %m\n");

exit(1);

    }

 

    /* Set a callback for requests to "/specific". */

    /* evhttp_set_cb(httpd, "/specific", another_handler, NULL); */

 

    /* Set a callback for all other requests. */

    evhttp_set_gencb(httpd, now_handler, NULL);

 

    event_dispatch();

 

    /* Not reached in this code as it is now. */

    evhttp_free(httpd);

 

    return 0;

}
