NAME

Net::Google - simple OOP-ish interface to the Google SOAP API

SYNOPSIS

 use Net::Google;
 use constant LOCAL_GOOGLE_KEY => "********************************";

 my $google = Net::Google->new(key=>LOCAL_GOOGLE_KEY);
 my $search = $google->search();

 # Search interface

 $search->query(qw(aaron straup cope));
 $search->lr(qw(en fr));
 $search->starts_at(5);
 $search->max_results(15);

 map { print $_->title()."\n"; } @{$search->results()};

 # or...

 foreach my $r (@{$search->response()}) {
   print "Search time :".$r->searchTime()."\n";

   # returns an array ref of Result objects
   # the same as the $search->results() method
   map { print $_->URL()."\n"; } @{$r->resultElements()};
 }

 # Spelling interface

 print $google->spelling(phrase=>"muntreal qwebec")->suggest(),"\n";

 # Cache interface

 my $cache = $google->cache(url=>"http://search.cpan.org/recent");
 print $cache->get();

DESCRIPTION

Provides a simple OOP-ish interface to the Google SOAP API

ENCODING

According to the Google API docs :

 "In order to support searching documents in multiple languages 
 and character encodings the Google Web APIs perform all requests 
 and responses in the UTF-8 encoding. The parameters <ie> and 
 <oe> are required in client requests but their values are ignored.
 Clients should encode all request data in UTF-8 and should expect
 results to be in UTF-8."

(This package takes care of setting both parameters in requests.)

PACKAGE METHODS

__PACKAGE__->new(\%args)

Valid arguments are :

• key

  string. A Google API key.

• http_proxy

  url. A URL for proxy-ing HTTP requests.

• debug

  Valid options are:

  • boolean

    If true prints debugging information returned by SOAP::Lite to STDERR

  • coderef.

    Your own subroutine for munging the debugging information returned by SOAP::Lite.

Note that prior to version 0.60, arguments were not passed by reference. Versions >= 0.60 are backwards compatible.

Returns an object. Woot!

OBJECT METHODS

$obj->key($string)

Get/set the Google API key for this object.

$obj->http_proxy($url)

Get/set the HTTP proxy for this object.

Returns a string.

$obj->search(\%args)

Valid arguments are :

• key

  string. A Google API key.

  If none is provided then the key passed to the parent Net::Google object will be used.

• starts_at

  int. First result number to display.

  Default is 0.

• max_results

  int. Number of results to return.

  Default is 10.

• lr

  string or array reference. Language restrictions.

• safe

  boolean.

• filter

  boolean.

• http_proxy

  url. A URL for proxy-ing HTTP requests.

• debug

  Valid options are:

  • boolean

    If true prints debugging information returned by SOAP::Lite to STDERR

  • coderef

    Your own subroutine for munging the debugging information returned by SOAP::Lite.

Note that prior to version 0.60, arguments were not passed by reference. Versions >= 0.60 are backwards compatible.

Returns a Net::Google::Search object. Woot!

Returns undef if there was an error.

$obj->spelling(\%args)

Valid arguments are:

• key

  string. A Google API key.

  If none is provided then the key passed to the parent Net::Google object will be used.

• phrase

  string or array reference.

• http_proxy

  url. A URL for proxy-ing HTTP requests.

• debug

  • boolean

    Prints debugging information returned by SOAP::Lite to STDERR

  • coderef

    Your own subroutine for munging the debugging information returned by SOAP::Lite.

  If no option is defined then the debug argument passed to the parent Net::Google object will be used.

Note that prior to version 0.60, arguments were not passed by reference. Versions >= 0.60 are backwards compatible.

Returns a Net::Google::Spelling object. Woot!

Returns undef if there was an error.

$obj->cache(\%args)

Valid arguments are :

• key

  String. Google API key.

  If none is provided then the key passed to the parent Net::Google object will be used.

• url

  string

• http_proxy

  url. A URL for proxy-ing HTTP requests.

• debug

  Valid options are:

  • boolean

    If true, prints debugging information returned by SOAP::Lite to STDERR

  • coderef

    Your own subroutine for munging the debugging information returned by SOAP::Lite.

  If no option is defined then the debug argument passed to the parent Net::Google object will be used.

Note that prior to version 0.60, arguments were not passed by reference. Versions >= 0.60 are backwards compatible.

Returns a Net::Google::Cache object. Woot!

Returns undef if there was an error.

$obj->queries_exhausted()

Returns true or false depending on whether or not the current in-memory session has exhausted the Google API 1000 query limit.

TO DO

• Tickle the tests so that they will pass on systems without Test::More.

• Add tests for filters.

• Add some sort of functionality for managing multiple keys. Sort of like what is describe here :

  http://aaronland.net/weblog/archive/4204

  This will probably happen around the time Hell freezes over so if you think you can do it faster, go nuts.
