NAME

POE::Component::Client::Whois::Smart - Provides very quick WHOIS queries with smart features.

DESCRIPTION

POE::Component::Client::Whois::Smart provides a very quick WHOIS queries with smart features to other POE sessions and components. The component will attempt to guess the appropriate whois server to connect to. Supports cacheing, HTTP-queries to some servers, stripping useless information, using more then one local IP, handling server's bans.

WARNING: This module changes body of POE::Filter::HTTPChunk to work correctly with DirectI SSL connection. See code for details.

            if ($result->{error}) {
                print "Can't resolve WHOIS-info for ".$result->{query}."\n";
            } else {
                print "QUERY: ".$result->{query}."\n";
                print "SERVER: ".$result->{server}."\n";
                print "WHOIS: ".$result->{whois}."\n\n";

Constructor

whois()

Creates a POE::Component::Client::Whois session. Takes two mandatory arguments and a number of optional:

query

query is an arrayref of domains, IPs or registaras to send to whois server. Required.

event

The event name to call on success/failure. Required.

session

A session or alias to send the above 'event' to, defaults to calling session. Optional.

server

Specify server to connect. Defaults try to be determined by the component. Optional.

referral

Optional.

0 - make just one query, do not follow if redirections can be done;

1 - follow redirections if possible, return last response from server; # default

2 - follow redirections if possible, return all responses;

Exapmle:

    #...
    POE::Component::Client::Whois->whois(
        query    => [ 'google.com', 'godaddy.com' ],
        event    => '_response',
        referral => 2,
    );
    #...
    sub _response {
        my $all_results = $_[ARG0];
        
        foreach my $result ( @{$all_results} ) {
            my $query = $result->{query} if $result;
            if ($result->{error}) {
                print "Can't resolve WHOIS-info for ".$result->{query}."\n";
            } else {
                print "Query for: ".$result->{query}."\n";
                # process all subqueries
                my $count = scalar @{$result->{subqueries}};
                print "There were $count subqueries:\n";
                foreach my $subquery (@{$result->{subqueries}}) {
                    print "\tTo server ".$subquery->{server}."\n";
                    # print "\tQuery: ".$subquery->{query}."\n";
                    # print "\tResponse:\n".$subquery->{whois}."\n";
                }
            }
        }

timeout

Cancel the request if connection is not made within a specific number of seconds. Default 30 sec.

local_ips

List of local IP addresses to use for WHOIS queries.

cache_dir

cache_time

Number of minutes to save cache. 1 minute by default.

exceed_wait

If exceed_wait true, will wait for for 1 minute and requery server in case if your IP banned for excessive querying. By default return 'Connection rate exceeded' in $result->{error};
