Weather::Bug - Provide an object oriented interface to the WeatherBug API.
This document describes Weather::Bug version 0.25
use Weather::Bug; my $wxbug = Weather::Bug->new( -key => 'YOURKEYHERE' );
The Weather::Bug module provides an object-oriented wrapper around the WeatherBug web API. An object of this class performs requests and parses the output to provide an easier interface for retrieving weather information.
Use of this module requires registering with WeatherBug to acquire a license key. This key provides a developer with access to the API.
The module supports several methods that access the WeatherBug API. In addition, the module supports a few convenience methods that simplify access to the underlying functionality by other classes.
The object is created using the
new class method. It takes a single required named parameter -key, whose value is the license key you obtained from WeatherBug.
The constructor also supports an optional parameter -getsub whose value is a
coderef that works as a standin for LWP::Simple::get. This is useful for testing, or if you need to get your data from somewhere other than an HTTP request.
These methods provide high-level access to the WeatherBug API.
This method takes one parameter, a US zipcode giving a start location to look for WeatherBug stations. The method returns a list of Weather::Bug::Station objects representing the stations near the requested location. The definition of near and the number of stations returned depends on the density of stations in the area of interest.
On failure, the method returns an empty list.
Retrieve the 7-day forecast for the supplied zipcode as a Weather::Bug::SevenDayForecast object.
On failure, the method returns
This method takes one parameter, a US zipcode giving a location to check for alerts. The method returns a list of Weather::Bug::Alert objects representing alerts that apply at the current time.
If there are no alerts, the method returns an empty list.
This method requires two named parameters: zipcode and StationID. The method provides access to what WeatherBug refers to as Live Compact Weather as a Weather::Bug::CompactWeather object.
This method requires two named parameters: zipcode and StationID. The method provides access to what WeatherBug refers to as Live Weather as a Weather::Bug::Weather object.
These utility methods are used by some of the other Weather::Bug classes to do their work. Some of these methods may be used for lower-level access to the WeatherBug API.
This method takes two parameters, a
cmd name and a hash containing parameters to pass to the command.
cmd parameter is the filename used in the URL for that API method, without the extension. Supported commands are:
This allows an extension point in the class. If WeatherBug extends their API, this method can be used to make a call in the same way as any of the other methods.
Using this method, the URL is created mostly automatically including the hostname, the file extension, and the acode parameter supplying the license key.
On success, the method returns the body of the response as a string. On failure, the method
This section lists error messages that this module may display.
Request for '%s' failed.
The request to the WeatherBug API was not successful. The
%s is the name of the page that failed.
Unable to parse output from '%s' request.
Although the WeatherBug API did return successfully, the output could not be parsed as well-formed XML. The
%s is the name of the page that failed.
No '%s' node found.
Although the WeatherBug API did return successfully, the output XML did not contain the specified node.
Weather::Bug requires no configuration files or environment variables.
