KHTTPBASIC_VALIDATE(3)

NAME
khttpbasic_validate - validate an HTTP basic authorisation request

LIBRARY
libkcgi

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
int
khttpbasic_validate(struct kreq *req, const char *user, const char *password);

DESCRIPTION
The khttpbasic_validate() function validates the given user and password with the HTTP basic-authorised request req as returned by khttp_parse(3) or khttp_fcgi_parse(3).

RETURN VALUES
khttpbasic_validate() will return zero if validation failed, less than zero if the request was not properly set up for HTTP basic validation (no HTTP method, not a basic request, not already authenticated by the web server), or greater than zero if the validation succeeded.

EXAMPLES
In the following fragment, assume r a pointer to a struct kreq successfully initialised by khttp_parse(3). If validation is not provided, it returns an HTTP 401. The expected principle is "james", password "bond". Otherwise, it returns an HTTP 200.

    if (khttpbasic_validate(r, "james", "bond") <= 0) {
      khttp_head(r, kresps[KRESP_STATUS],
        "%s", khttps[KHTTP_401]);
      khttp_head(r, kresps[KRESP_WWW_AUTHENTICATE],
        "basic realm=\"%s\"", "some realm");
    } else
      khttp_head(r, kresps[KRESP_STATUS],
        "%s", khttps[KHTTP_200]);
