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.
