NAME

Weather::WeatherKit - Apple WeatherKit REST API client

VERSION

Version 0.01

SYNOPSIS

use Weather::WeatherKit;

my $wk = Weather::WeatherKit->new(
    team_id    => $apple_team_id,          # Your 10-char Developer Team Id
    service_id => $weatherkit_service_id,  # The WeatherKit Service Id
    key_id     => $key_id,                 # ID of the WeatherKit developer key
    key        => $private_key             # Encrypted private key (PEM)
);

my $report = $wk->get(
    lat      => $lat,      # Latitude
    lon      => $lon,      # Longitude
    dataSets => $datasets  # e.g. currentWeather - comma-separated list
);

DESCRIPTION

Weather::WeatherKit provides basic access to the Apple WeatherKit REST API (v1). WeatherKit replaces the Dark Sky API and requires an Apple developer subscription.

Pease see API documentation: https://developer.apple.com/documentation/weatherkitrestapi for dataSets and usage options as well as the required attribution.

It was made to serve the apps Xasteria and Polar Scope Align, but if your service requires some extra functionality, feel free to contact the author about it.

CONSTRUCTOR METHOD

new

  my $wk = Weather::WeatherKit->new(
      team_id    => "MLU84X58U4",
      service_id => "com.domain.myweatherapp",
      key_id     => $key_id,
      key        => $private_key?,
      key_file   => $private_key_pem?,
      language   => $lang_code?,
      timeout    => $timeout_sec?,
      expiration => $expire_secs?,
      ua         => $lwp_ua?,
      curl       => $use_curl?
  );

Required parameters:

  • team_id : Your 10-character Apple developer Team Id - it can be located on the Apple developer portal.

  • service_id : The WeatherKit Service Identifier created on the Apple developer portal. Usually a reverse-domain type string is used for this.

  • key_id : The ID of the WeatherKit key created on the Apple developer portal.

  • key_file : The encrypted WeatherKit private key file that you created on the Apple developer portal. On the portal you download a PKCS8 format file (.p8), which you first need to convert to the PEM format. On a Mac you can convert it simply:

    openssl pkcs8 -nocrypt -in AuthKey_<key_id>.p8 -out AuthKey_<key_id>.pem

  • key : Instead of the .pem file, you can pass its contents directly as a string.

Optional parameters:

  • language : Language code. Default: en_US.

  • timeout : Timeout for requests in secs. Default: 30.

  • ua : Pass your own LWP::UserAgent to customise the agent string etc.

  • curl : If true, fall back to using the curl command line program. This is useful if you have issues adding http support to LWP::UserAgent, which is the default method for the WeatherKit requests.

  • expiration : Token expiration time in seconds. Tokens are cached until there are less than 10 minutes left to expiration. Default: 7200.

METHODS

get

my $report = $wk->get(
    lat      => $lat,
    lon      => $lon,
    dataSets => $datasets
    %args?
);

my %report = $wk->get( ... );

Fetches datasets (weather report, forecast, alert...) for the requested location. Returns a string containing the JSON data, except in array context, in which case, as a convenience, it will use JSON to decode it directly to a Perl hash.

If the request is not successful, it will die throwing the HTTP::Response->status_line.

  • lat : Latitude (-90 to 90).

  • lon : Longitude (-18 to 180).

  • dataSets : A comma-separated string of the dataset(s) you request. Example supported data sets: currentWeather, forecastDaily, forecastHourly, forecastNextHour, weatherAlerts. Some data sets might not be available for all locations. Will return empty results if parameter is missing.

  • %args : See the official API documentation for the supported weather API query parameters which you can can pass as key/value pairs.

get_response

my $response = $wk->get_response(
    lat      => $lat,
    lon      => $lon,
    dataSets => $datasets
    %args?
);

Same as get except it returns the full HTTP::Response from the API (so you can handle bad requests yourself).

CONVENIENCE METHODS

jwt

my $jwt = $wk->jwt(
    iat => $iat?,
    exp => $exp?
);

Returns the JSON Web Token string in case you need it. Will return a cached one if it has more than 10 minutes until expiration and you don't explicitly pass an exp argument.

  • iat : Specify the token creation timestamp. Default is time().

  • exp : Specify the token expiration timestamp. Passing this parameter will force the creation of a new token. Default is time()+7200 (or what you specified in the constructor).
