NAME

WebService::Mojang::Minecraft::UUIDLookup - look up Minecraft usernames/UUIDs

DESCRIPTION

A simple module to use Mojang's API to look up a Minecraft user's UUID from their username (and provide any previous names they've had), or given a UUID, return all names that account has had.

SYNOPSIS

use WebService::Mojang::Minecraft::UUIDLookup;

my $mojang_lookup = WebService::Mojang::Minecraft::UUIDLookup->new();

# Look up a username and get their UUID and previous names
if (my $user_details = $mojang_lookup->lookup_user($username)) {
    say "$username's UUID is " . $user_details->{uuid};
    if ($user_details->{previous_names}) {
         say "Previous names for $username: " 
            . join ',', @{ $user_details->{previous_names} };
    }
} else {
    warn "Username $username not found";
}

# Or lookup a UUID and find the current username, and any previous ones
if (my $user_details = $mojang_lookup->lookup_uuid($user_uuid)) {
    say "$user_uuid is $user_details->{username}";
    if ($user_details->{previous_names}) {
        say "Previous names for $user_details_>{username}: "
            . join ',', @{ $user_details->{previous_names} };
    }
} else {
    warn "UUID $user_uuid not found";
}

Methods

lookup_user

Given a username, return their UUID and any previous usernames they had (unless the lookup_previous_usernames option is set to a false value; it defaults to enabled, but if you don't care about previous usernames and want to save an API call you can disable it.

Returns undef if Mojang indicated no match, otherwise a hash (in list context) or hashref (in scalar context) with the keys:

uuid

The UUID for this username; this identifies the Mojang account, and does not change, even if the user renames their account.

formatted_uuid

The UUID for this username - as uuid, but formatted using Data::UUID's to_string method (e.g. 85d699cb21774d538366f2cdf9dc93cd as returned by Mojang becomes 36643538-3939-6263-3231-373734643533).

username

The current username for this account

previous_usernames

An arrayref of previous usernames this account has been known by, unless the lookup_previous_usernames attribute is set to a false value.

If the account wasn't found, returns undef. Dies if it wasn't possible to retrieve a response from Mojang.

lookup_uuid

Given a Mojang account UUID, returns a hash (in list context) or a hashref (in scalar context) with the following keys:

uuid

The account's UUID (as you supplied)

username

The account's current username

previous_usernames

Any previous usernames this account has used.

If the account wasn't found, returns undef. Dies if it wasn't possible to retrieve a response from Mojang.
