REST::Google::Search - OO interface to Google Search API
use REST::Google::Search;
REST::Google::Search->http_referer('http://example.com');
my $res = REST::Google::Search->new(
q => 'Larry Wall',
);
die "response status failure" if $res->responseStatus != 200;
my $data = $res->responseData;
my $cursor = $data->cursor;
my $pages = $cursor->pages;
printf "current page index: %s\n", $cursor->currentPageIndex;
printf "estimated result count: %s\n", $cursor->estimatedResultCount;
my @results = $data->results;
foreach my $r (@results) {
printf "\n";
printf "title: %s\n", $r->title;
printf "url: %s\n", $r->url;
}
"REST::Google::Search" provides OO interface
to Google REST (aka AJAX) API for searching.
- __PACKAGE__->service()
- Get/set service to use.
The following table lists the URL used to access Google search
services:
service address
------- ------------------------------------------------------
WEB http://ajax.googleapis.com/ajax/services/search/web
VIDEO http://ajax.googleapis.com/ajax/services/search/video
NEWS http://ajax.googleapis.com/ajax/services/search/news
LOCAL http://ajax.googleapis.com/ajax/services/search/local
IMAGES http://ajax.googleapis.com/ajax/services/search/images
BOOKS http://ajax.googleapis.com/ajax/services/search/books
BLOGS http://ajax.googleapis.com/ajax/services/search/blogs
PATENT http://ajax.googleapis.com/ajax/services/search/patent
Service constants are exported on demand, so you can use the
constants instead of service URLs:
use REST::Google::Search qw/VIDEO/;
REST::Google::Search->service( VIDEO );
Default service is
"WEB".
- __PACKAGE__->http_referer()
- Get/set HTTP "Referer" header.
Note: Google says that you should supply a valid HTTP
referer header each time you perform a request to their AJAX API, so
"new()" raises warning unless referer
is specified.
- __PACKAGE__->new()
- The constructor use it's arguments to build a valid HTTP GET request to
Google Search service, so it takes the same arguments as the web service
takes. Please refer to 'Google Search AJAX API' documentation for complete
list of arguments for Google Search. E.g.:
my $res = REST::Google::Search->new(
q => 'Pamela Anderson',
start => 4,
hl => 'fr'
);
If you're using the default (WEB) search, the code above will
perform a following HTTP GET request:
http://ajax.googleapis.com/ajax/services/search/web?hl=fr&q=Pamela+Anderson&v=1.0&start=4
Note: You can left protocol version number unspecified
while making your searches since
"v=1.0" is passed by default.
"REST::Google::Search" contains dedicated
classes for each of supported search services. You may use them instead of
specifying certain service with "service"
class method. E.g:
use REST::Google::Search::Blogs;
# ...
# set referer, etc
my $r = REST::Google::Search::Blogs->new( q => 'foobar' );
is the same as:
use REST::Google::Search qw/BLOGS/;
REST::Google::Search->service( BLOGS );
# ...
# set referer, etc
my $r = REST::Google::Search->new( q => 'foobar' );
Available classes:
- REST::Google::Search::Web
- REST::Google::Search::Blogs
- REST::Google::Search::Books
- REST::Google::Search::Images
- REST::Google::Search::Local
- REST::Google::Search::Video
- REST::Google::Search::News
- REST::Google::Search::Patent
