NAME Net::Google::Drive::Simple - Simple modification of Google Drive data SYNOPSIS use feature 'say'; use Net::Google::Drive::Simple; # requires a ~/.google-drive.yml file with an access token, # see description below. my $gd = Net::Google::Drive::Simple->new( 'version' => 3 ); # v3 interface (RECOMMENDED!) my $gd = Net::Google::Drive::Simple->new(); # v2 interface (OUTDATE!) my $children = $gd->children( "/" ); # or any other folder /path/location foreach my $item ( @$children ) { # item is a Net::Google::Drive::Simple::Item object if ( $item->is_folder ) { say "** ", $item->title, " is a folder"; } else { say $item->title, " is a file ", $item->mimeType; eval { # originalFilename not necessary available for all files say $item->originalFilename(), " can be downloaded at ", $item->downloadUrl(); }; } } DESCRIPTION Net::Google::Drive::Simple authenticates with a user's Google Drive and offers several convenience methods to list, retrieve, and modify the data stored in the 'cloud'. See "eg/google-drive-upsync" as an example on how to keep a local directory in sync with a remote directory on Google Drive. All methods are documented based on the version you use: * V3 (recommended) # Create default V3 API: my $gd = Net::Google:Drive::Simple->new( 'version' => 3 ); The methods available are documented in Net::Google::Drive::Simple::V3. * V2 (default, outdated) # Create default V2 API: my $gd = Net::Google:Drive::Simple->new(); # or: my $gd = Net::Google:Drive::Simple->new( 'version' => 2 ); The methods available are documented in Net::Google::Drive::Simple::V2. GETTING STARTED To get the access token required to access your Google Drive data via this module, you need to run the script "eg/google-drive-init" in this distribution. Before you run it, you need to register your 'app' with Google Drive and obtain a client_id and a client_secret from Google: https://developers.google.com/drive/web/enable-sdk Click on "Enable the Drive API and SDK", and find "Create an API project in the Google APIs Console". On the API console, create a new project, click "Services", and enable "Drive API" (leave "drive SDK" off). Then, under "API Access" in the navigation bar, create a client ID, and make sure to register a an "installed application" (not a "web application"). "Redirect URIs" should contain "http://localhost". This will get you a "Client ID" and a "Client Secret". Then, replace the following lines in "eg/google-drive-init" with the values received: # You need to obtain a client_id and a client_secret from # https://developers.google.com/drive to use this. my $client_id = "XXX"; my $client_secret = "YYY"; Then run the script. It'll start a web server on port 8082 on your local machine. When you point your browser at http://localhost:8082, you'll see a link that will lead you to Google Drive's login page, where you authenticate and then allow the app (specified by client_id and client_secret above) access to your Google Drive data. The script will then receive an access token from Google Drive and store it in ~/.google-drive.yml from where other scripts can pick it up and work on the data stored on the user's Google Drive account. Make sure to limit access to ~/.google-drive.yml, because it contains the access token that allows everyone to manipulate your Google Drive data. It also contains a refresh token that this library uses to get a new access token transparently when the old one is about to expire. METHODS "new()" Constructor, creates a helper object to retrieve Google Drive data later. While v2 (the outdated version) is still supported by Google, we recommend you use v3: # Returns object of Net::Google::Drive::Simple::V3 my $gd = Net::Google::Drive::Simple->new( 'version' => 3 ); # Returns object of Net::Google::Drive::Simple::V2 my $gd = Net::Google::Drive::Simple->new( 'version' => 2 ); # or: my $gd = Net::Google::Drive::Simple->new(); Read up on the methods in each class: Net::Google::Drive::Simple::V3 and Net::Google::Drive::Simple::V2. Error handling In case of an error while retrieving information from the Google Drive API, the methods above will return "undef" and a more detailed error message can be obtained by calling the "error()" method: print "An error occurred: ", $gd->error(); LOGGING/DEBUGGING Net::Google::Drive::Simple is Log4perl-enabled. To find out what's going on under the hood, turn on Log4perl: use Log::Log4perl qw(:easy); Log::Log4perl->easy_init($DEBUG); LEGALESE Copyright 2012-2019 by Mike Schilli, all rights reserved.
