NAME
Captcha::reCAPTCHA::V3 - A Perl implementation of reCAPTCHA API version v3
SYNOPSIS
Captcha::reCAPTCHA::V3 provides you to integrate Google reCAPTCHA v3 for your web applications.
use Captcha::reCAPTCHA::V3;
my $rc = Captcha::reCAPTCHA::V3->new(
sitekey => '__YOUR_SITEKEY__', # Optional
secret => '__YOUR_SECRET__', # Required
);
...
my $content = $rc->verify($param{$rc});
unless ( $content->{'success'} ) {
# code for failing like below
die 'fail to verify reCAPTCHA: ', @{ $content->{'error-codes'} }, "\n";
}
DESCRIPTION
Captcha::reCAPTCHA::V3 is inspired from Captcha::reCAPTCHA::V2
This one is especially for Google reCAPTCHA v3, not for v2 because APIs are so defferent.
Basic Usage
new( secret => secret, [ sitekey => sitekey, query_name => query_name ] )
Requires only secret when constructing.
Now you can omit sitekey (from version 0.0.4).
You have to get them before running from here.
my $rc = Captcha::reCAPTCHA::V3->new(
sitekey => '__YOUR_SITEKEY__', # Optinal
secret => '__YOUR_SECRET__',
query_name => '__YOUR_QUERY_NAME__', # Optinal
);
According to the official document, query_name defaults to 'g-recaptcha-response' so if you changed it another, you have to set query_name as same.
name([name])
You can get/set query_name after constuct the object from version 0.0.4
my $query_name = $rc->name(); # defaults to 'g-recaptcha-response'
$rc->name('captcha'); # the I<query_name> is now 'captcha'
and with overlording, you can get query_name with just like below:
my $query_name = "$rc"; # means same with $rc->name();
verify( response )
Requires just only response key being got from Google reCAPTCHA API.
DO NOT add remote address. there is no function for remote address within reCAPTCHA v3.
my $content = $rc->verify($param{$rc});
The default query_name is 'g-recaptcha-response' and it is stocked in constructor.
But now string-context provides you to get query_name so we don't have to care about it.
The response contains JSON so it returns decoded value from JSON.
unless ( $content->{'success'} ) {
# code for failing like below
die 'fail to verify reCAPTCHA: ', @{ $content->{'error-codes'} }, "\n";
}
deny_by_score( response => response, [ score => expected ] )
reCAPTCHA v3 responses have score whether the request was by bot.
So this method provides evaluation by scores that 0.0~1.0(defaults to 0.5)
If the score was lower than what you expected, the verifying is fail with inserting 'too-low-score' into top of the error-codes.
verify()
requires just only one argument because of compatibility for version 0.01.
In this method, the response pair SHOULD be set as a hash argument(score pair is optional).
Additional method for lazy(not sudgested)
verify_or_die( response => response, [ score => score ] )
This method is a wrapper of deny_by_score()
, the differense is dying imidiately when fail to verify.
scripts( id => ID, [ debug => Boolen, action => action ] )
You can insert this somewhere in your <body> tag.
In ordinal HTMLs, you can set this like below:
print <<"EOL", scripts( id => 'MailForm' );
<form action="./" method="POST" id="MailForm">
<input type="hidden" name="name" value="value">
<button type="submit">send</button>
</form>
EOL
Then you might write less javascript lines.
From 0.0.4 you can set debug flag in this method. this is just comment-out the below but powerful.
//console.log(token);
NOTES
To test this module strictly, there is a necessary to run javascript in test environment.
I have not prepared it yet.
So any PRs and Issues are welcome.
