Apache Modules

tame1 has asked for the wisdom of the Perl Monks concerning the following question:

I followed a small tutorial and was able to modify my Apache to write accesses to one certain directory into a database, by makeing a

Everything is fine, accept one small thing: I cannot seem to grab the environment variable REMOTE_USER no matter what method I use.

I know for a fact that it is set, as I had to enter a username/pass combo just to access the directory I am logging.

Here is the code I am using:

package Apache::TaartsLog; use CGI qw(:cgi); use Apache (); use Apache::Constants qw(:common &OPT_EXECCGI &REDIRECT); use DBI; my $query = new CGI(); $dbh = DBI->connect("dbi:mysql:taarts","jrobiso2","") || die "$DBI::er +rstr: $!\n"; sub handler { my $r = shift; # @_[0] contains a reference to # the current request handler my ($request); my ($hostname); # Returns a blessed reference if ($r->main) { # unless this is the main request $orig = $r->main; } else { $orig = $r; } $hostname = $orig->get_remote_host; $request = $orig->filename; $user = $query->remote_user(); # this apparently fails. unless (($request =~ /jpg/) || ($request =~ /gif/)) { $dbh->do("insert into logs (host,request,time_stamp,cdsid) +VALUES ('$hostname','$request',NOW(),'$user')"); } } END { undef($dbh); } 1;

Can anyone tell me why the $query->remote_user() is failing? The other three fields get written to the database just fine. Only the remote_user is always blank.

    And now that I think about it a bit more... If all you're using the CGI object for is to get the remote user name, why not just use:
    instead? That will return the user name typed in for Basic authentication. You can also get the password from:
    ($ret,$pw) = $r->get_basic_auth_pw().


      Thanks for the $r->connection->user(); It worked!

      I had searched through, etc. looking for such a thing. Is there a better write-up somewhere? (Before you answer, I own "Programming Apache Modules with Perl" but just haven't read it yet!)

    The code outside your handler ( my $query = new CGI() ) will get executed at server startup. Only code inside your handler gets executed on each request. Try moving that line inside your handler and see what happens.

    The basic problem is that you are using in a non-CGI environment. When invoking a CGI the apache server handler for CGIs sets up the environment variables and STDIN/STDOUT filehandles just before it executes the CGI program. The CGI apache handler sets up the CGI runtime environment *from* the info contained/accessable in the $r request object.

    The big "Ahha!" experience for me was to realize that the $r request object is the rough equivalent of the $q query object. Actually the $r request object has alot more info in it, which is great.
