DESCRIPTION

Mojolicious::Plugin::BlogSpam is a plugin for Mojolicious to test comments or posts for spam against a BlogSpam instance (see Blog::Spam::API for the codebase). It supports blocking as well as non-blocking requests.

  log_level => 'debug',
  exclude   => 'badip',
  mandatory => [qw/name subject/]
});

# Mojolicious::Lite
plugin 'BlogSpam' => {
  site => 'http://grimms-abenteuer.de/'
};

# Or in your config file

  BlogSpam => {
    url => 'blogspam.sojolicious.example',
    site => 'http://grimms-abenteuer.de/',
    port => '8888'
  }
}

HELPERS

blogspam

# In controller:
my $bs = $c->blogspam(
  comment => 'This is a comment to test the system',
  name => 'Akron'
);

Returns a new blogspam object, based on the given attributes.

OBJECT ATTRIBUTES

These attributes are primarily based on the BlogSpam API.

agent

my $agent = $bs->agent;

The user-agent sending the comment. Defaults to the user-agent of the request.

comment

my $comment_text = $bs->comment;

The comment text.

email

$bs->email('spammer@sojolicious.example');
my $email = $bs->email;

The email address of the commenter.

hash

my $hash = $bs->hash;

Returns a hash representation of the comment.

ip

$bs->ip('192.168.0.1');
my $ip = $bs->ip;

The ip address of the commenter. Defaults to the ip address of the request. Supports X-Forwarded-For proxy information.

my $link = $bs->link;

Homepage link given by the commenter.

my $name = $bs->name;

Name given by the commenter.

subject

$bs->subject('Fun');
my $subject = $bs->subject;

OBJECT METHODS

These methods are based on the BlogSpam API.

test_comment

# Blocking
if ($bs->test_comment(
       mandatory => 'name',
       blacklist => ['192.168.0.1']
    )) {
  print 'Probably ham!';
} else {
  print 'Spam!';
};

# Non-blocking
$bs->test_comment(
  mandatory => 'name',
  blacklist => ['192.168.0.1'],
  sub {
    my $result = shift;
    print ($result ? 'Probably ham!' : 'Spam!');
  }
);

Test the comment of the blogspam object for spam or ham. It's necessary to have a defined comment text and an IP address. The method returns nothing in case the comment is detected as spam, 1 if the comment is detected as ham and -1 if something went horribly, horribly wrong. Accepts additional option parameters as defined in the BlogSpam API.

blacklist

Blacklist an IP or an array reference of IPs. This can be either a literal IP address ("192.168.0.1") or a CIDR range ("192.168.0.1/8").

exclude

Exclude a plugin or an array reference of plugins from testing. See "get_plugins" for installed plugins of the BlogSpam instance.

fail

Boolean flag that will, if set, return every comment as spam.

mandatory

Define an attribute (or an array reference of attributes) of the blogspam object, that should be treated as mandatory (e.g. "name" or "subject").

The maximum number of links allowed in the comment. This defaults to 10.

max-size

The maximum size of the comment text allowed, given as a byte expression (e.g. "2k").

min-size

The minimum size of the comment text needed, given as a byte expression (e.g. "2k").

min-words

The minimum number of words of the comment text needed. Defaults to 4.

whitelist

Whitelist an IP or an array reference of IPs. This can be either a literal IP address ("192.168.0.1") or a CIDR range ("192.168.0.1/8").

For a non-blocking request, append a callback function. The parameters of the callback are identical to the method's return values in blocking requests.

classify_comment

$bs->classify_comment('ok');
$bs->classify_comment(ok => sub {
  print 'Done!';
});

Train the BlogSpam instance based on your comment definition as ok or spam. This may help to improve the spam detection. Expects a defined comment attribute and a single parameter, either ok or spam.

For a non-blocking request, append a callback function. The parameters of the callback are identical to the method's return values in blocking requests.

get_plugins

my @plugins = $bs->get_plugins;
$bs->get_plugins(sub {
  print join ', ', @_;
});

Requests a list of plugins installed at the BlogSpam instance.

For a non-blocking request, append a callback function. The parameters of the callback are identical to the method's return values in blocking requests.

get_stats

my $stats = $bs->get_stats;
my $stats = $bs->get_stats('http://sojolicious.example/');
$bs->get_stats(sub {
  my $stats = shift;
  ...
});

Requests a hash reference of statistics for your site regarding the number of comments detected as ok or spam. If no site attribute is given (whether as a parameter or when registering the plugin), this will return nothing.

For a non-blocking request, append a callback function. The parameters of the callback are identical to the method's return values in blocking requests.
