NAME

WWW::Wunderground::API - Use Weather Underground's JSON/XML API

VERSION

Version 0.06

SYNOPSIS

Connects to the Weather Underground JSON/XML service and parses the data into something usable. The entire response is available in Hash::AsObject form, so any data that comes from the server is accessible. Print a Data::Dumper of ->data to see all of the tasty data bits.

use WWW::Wunderground::API;

#location
my $wun = new WWW::Wunderground::API('Fairfax, VA');

#or zipcode
my $wun = new WWW::Wunderground::API('22030');

#or airport identifier
my $wun = new WWW::Wunderground::API('KIAD');

#using the options

my $wun = new WWW::Wunderground::API(
  location=>'22152',
  api_key=>'my wunderground api key',
  auto_api=>1,
  cache=>Cache::FileCache->new({ namespace=>'wundercache', default_expires_in=>2400 }) #A cache is probably a good idea. 
);


#Check the wunderground docs for details, but here are just a few examples 
print 'The temperature is: '.$wun->conditions->temp_f."\n"; 
print 'The rest of the world calls that: '.$wun->conditions->temp_c."\n"; 
print 'Record high temperature year: '.$wun->almanac->temp_high->recordyear."\n";
print "Sunrise at:".$wun->astronomy->sunrise->hour.':'.$wun->astronomy->sunrise->minute."\n";
print "Simple forecast:".$wun->forecast->simpleforecast->forecastday->[0]{conditions}."\n";
print "Text forecast:".$wun->forecast->txt_forecast->forecastday->[0]{fcttext}."\n";
print "Long range forecast:".$wun->forecast10day->txt_forecast->forecastday->[9]{fcttext}."\n";
print "Chance of rain three hours from now:".$wun->hourly->[3]{pop}."%\n";
print "Nearest airport:".$wun->geolookup->nearby_weather_stations->airport->{station}[0]{icao}."\n";

#Conditions is autoloaded into the root of the object
print "Temp_f:".$wun->temp_f."\n";

METHODS/ACCESSORS

update()

Included for backward compatibility only. Refetches conditions data from the server. It will be removed in a future release. If you specify an api_key then this is equvilent of ->api_call('conditions') and is subject to the same cache

location()

Set the location. For example:

my $wun = new WWW::Wunderground::API('22030');
my $ffx_temp = $wun->conditions->temp_f;

$wun->location('KJFK');
my $ny_temp = $wun->conditions->temp_f;

$wun->location('San Diego, CA');
my $socal_temp = $wun->conditions->temp_f;

Valid locations can be derived from others by calling the geolookup endpoint, but you probably already know where you are.

auto_api

set auto_api to something truthy to have the module automatically make API calls without the use of api_call()

api_call( api_name, <location> )

Set api_name to any location-based wunderground api call (almanac,conditions,forecast,history...).

Location is optional and defaults to "location()". Can be any valid location (eg 22152,'KIAD','q/CA/SanFrancisco',...)

#Almanac data for 90210
$wun->api_call('almanac','90210');

#If auto_api=>1 the following is equivalent
$wun->location(90120);
$wun->almanac;

#10 day forecast for New York
$wun->api_call('forecast10day'','KJFK');

raw()

Returns raw text result from the most recent API call. This will be either xml or json depending on api_type. You can also set this to whatever json/xml you'd like, though I can't imagine why you'd want to.

cache()

Specify a cache object. Needs only to support get(key) and set (key,value) so Cache::Cache or CLI caches should work.

xml()

*Deprecated* - use "raw()" instead.

Returns raw xml result from wunderground server where applicable

json()

*Deprecated* - use "raw()" instead.

Returns raw json result from wunderground server where applicable

data()

Contains all weather data from server parsed into convenient Hash::AsObject form;

api_key()

Required for JSON api access. Defaults to $ENV{WUNDERGROUND_API}

api_type()

Defaults to json. If no api_key is specified it will be set to xml and only basic weather conditions will be available.
