NAME

Yahoo::BBAuth - Perl interface to the Yahoo! Browser-Based Authentication.

SYNOPSIS

      my $bbauth = Yahoo::BBAuth->new(
          appid  => $appid,
          secret => $secret,
      );
      # Get your appid and secret by registering your application here:
      # https://developer.yahoo.com/wsregapp/index.php
      # Create an authentication link
      printf '<a href="%s">Click here to authorize</a>', $bbauth->auth_url; 
      # You can include some application data or return a user hash using optional params:
      printf '<a href="%s">Click here to authorize</a>', $bbauth->auth_url(
          send_userhash  => '1',
          appdata => 'someappdata',
          );  
      # After the user authenticates successfully, Yahoo returns the user to the page you
      # dictated when you signed up. To verify whether authentication succeeded, you need to
      # validate the signature:
      if (!$bbauth->validate_sig()) {
      print '<h2>Authentication Failed. Error is: </h2>'.$bbauth->{sig_validation_error};
      exit(0);
      }
      # You can then make an authenticated web service call on behalf of the user
      # For Yahoo! Mail:
      my $json = $bbauth->make_jsonrpc_call('ListFolders', [{}] );
      if (!$json) {
            print '<h2>Web services call failed. Error is:</h2> '. $bbauth->{access_credentials_error};
            exit(0);
      }
      # For Yahoo! Photos:
      my $url = 'http://photos.yahooapis.com/V3.0/listAlbums?';
      my $xml = $bbauth->auth_ws_get_call($url);
      if (!$xml) {
          print '<h2>Web services call failed. Error is:</h2> '. $bbauth->{access_credentials_error};
          exit(0);
      }

DESCRIPTION

This module priovides an Object Oriented interface for Yahoo! Browser-Based Authentication.

This module is ported from the official PHP class which is located on this page: http://developer.yahoo.com/php

METHODS

new(appid => $appid, secret => $secret)

Returns an instance of this module. You must set the your application id and shared secret.

auth_url(%param)

Create the Login URL used to fetch authentication credentials. This is the first step in the browser authentication process.

You can set the %param to send_userhash and appdata if you need(optional).

The appdata typically a session id that Yahoo will transfer to the target application upon successful authentication.

If send_userhash set, the send_userhash=1 request will be appended to the request URL so that the userhash will be returned by Yahoo! after successful authentication.

validate_sig

Validates the signature returned by Yahoo's browser authentication services.

Returns false if the sig is invalid. Returns 0 if any error occurs. If 0 is returned, $self->sig_validation_error should contain a string describing the error.

Make an authenticated web services call using HTTP GET. Returns response if successful, a string is returned containing the web service response which might be XML, JSON, or some other type of text. If an error occurs, 0 is returned, and the error is stored in $self->access_credentials_error.

ACCESSORS
