CONSTRUCTOR
Parse
The Parse method will decode and validate a base64 encoded version of the tcf v2 string.
Will die if can't decode the string.
use GDPR::IAB::TCFv2;
my $consent = GDPR::IAB::TCFv2->Parse(
'CLcVDxRMWfGmWAVAHCENAXCkAKDAADnAABRgA5mdfCKZuYJez-NQm0TBMYA4oCAAGQYIAAAAAAEAIAEgAA.argAC0gAAAAAAAAAAAA'
);METHODS
version
Version number of the encoding format. The value is 2 for this format.
created
Epoch time format when TC String was created in numeric format. You can easily parse with DateTime if needed.
last_updated
Epoch time format when TC String was last updated in numeric format. You can easily parse with DateTime if needed.
cmp_id
Consent Management Platform ID that last updated the TC String. Is a unique ID will be assigned to each Consent Management Platform.
cmp_version
Consent Management Platform version of the CMP that last updated this TC String. Each change to a CMP should increment their internally assigned version number as a record of which version the user gave consent and transparency was established.
consent_screen
CMP Screen number at which consent was given for a user with the CMP that last updated this TC String. The number is a CMP internal designation and is CmpVersion specific. The number is used for identifying on which screen a user gave consent as a record.
consent_language
Two-letter ISO 639-1 language code in which the CMP UI was presented.
vendor_list_version
Number corresponds to GVL vendorListVersion. Version of the GVL used to create this TC String.
is_purpose_consent_allowed
The user's consent value for each Purpose established on the legal basis of consent.
my $ok = $instance->is_purpose_consent_allowed(1);is_purpose_legitimate_interest_allowed
The user's consent value for each Purpose established on the legal basis of legitimate interest.
my $ok = $instance->is_purpose_legitimate_interest_allowed(1);purpose_one_treatment
CMPs can use the PublisherCC field to indicate the legal jurisdiction the publisher is under to help vendors determine whether the vendor needs consent for Purpose 1.
Returns true if Purpose 1 was NOT disclosed at all.
Returns false if Purpose 1 was disclosed commonly as consent as expected by the Policies.
publisher_country_code
Two-letter ISO 639-1 language code of the country that determines legislation of reference. Commonly, this corresponds to the country in which the publisher's business entity is established.
max_vendor_id_consent
The maximum Vendor ID that is represented in the following bit field or range encoding.
Because this section can be a variable length, this indicates the last ID of the section so that a decoder will know when it has reached the end.
vendor_consent
The consent value for each Vendor ID
max_vendor_id_legitimate_interest
The maximum Vendor ID that is represented in the following bit field or range encoding.
Because this section can be a variable length, this indicates the last ID of the section so that a decoder will know when it has reached the end.
vendor_legitimate_interest
The legitimate interest value for each Vendor ID
