Captcha::reCAPTCHA::V3(3pm)

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 <https://www.google.com/recaptcha/intro/v3.html>.

 my $rc = Captcha::reCAPTCHA::V3->new(
    sitekey => '__YOUR_SITEKEY__', # Optional
    secret  => '__YOUR_SECRET__',
    query_name => '__YOUR_QUERY_NAME__', # Optional
 );

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);
