DESCRIPTION

WebService::Dropbox is Perl interface to Dropbox API

- Support Dropbox v2 REST API

- Support Furl (Fast!!!)

- Streaming IO (Low Memory)

API v1 => v2 Migration guide

Migration API

files => download, files_put => upload ...etc

https://www.dropbox.com/developers/reference/migration-guide

Migration OAuth1 Token => OAuth2 Token

use WebService::Dropbox::TokenFromOAuth1;

my $oauth2_access_token = WebService::Dropbox::TokenFromOAuth1->token_from_oauth1({
    consumer_key    => $dropbox->key,
    consumer_secret => $dropbox->secret,
    access_token    => $access_token,  # OAuth1 access_token
    access_secret   => $access_secret, # OAuth1 access_secret
});

warn $oauth2_access_token;

Use API v1

Dropbox will be turning off API v1 on 6/28/2017.

print "Please Input Code: ";

chomp( my $code = <STDIN> );

unless ($dropbox->token($code)) {
    die $dropbox->error;
}

for Web Sample

use Amon2::Lite;
use WebService::Dropbox;

__PACKAGE__->load_plugins('Web::JSON');

my $key = $ENV{DROPBOX_APP_KEY};
my $secret = $ENV{DROPBOX_APP_SECRET};
my $dropbox = WebService::Dropbox->new({ key => $key, secret => $secret });

my $redirect_uri = 'http://localhost:5000/callback';

get '/' => sub {
    my ($c) = @_;

    my $url = $dropbox->authorize({ redirect_uri => $redirect_uri });

    return $c->redirect($url);
};

get '/callback' => sub {
    my ($c) = @_;

    my $code = $c->req->param('code');

    my $token = $dropbox->token($code, $redirect_uri);

    my $account = $dropbox->get_current_account || { error => $dropbox->error };

    return $c->render_json({ token => $token, account => $account });
};

__PACKAGE__->to_app();

authorize(\%optional_params)

# for Simple CLI
my $url = $dropbox->authorize();

# for Other
my $url = $dropbox->authorize({
    response_type => 'code', # code or token
    redirect_uri => '',
    state => '',
    require_role => '',
    force_reapprove => JSON::false,
    disable_signup => JSON::false,
});

https://www.dropbox.com/developers/documentation/http/documentation#oauth2-authorize

token($code [, $redirect_uri])

This endpoint only applies to apps using the authorization code flow. An app calls this endpoint to acquire a bearer token once the user has authorized the app.

Calls to /oauth2/token need to be authenticated using the apps's key and secret. These can either be passed as POST parameters (see parameters below) or via HTTP basic authentication. If basic authentication is used, the app key should be provided as the username, and the app secret should be provided as the password.

# for CLI
my $token = $dropbox->token($code);

# for Web
my $token = $dropbox->token($code, $redirect_uri);

https://www.dropbox.com/developers/documentation/http/documentation#oauth2-token

revoke

Disables the access token used to authenticate the call.

my $result = $dropbox->revoke;

https://www.dropbox.com/developers/documentation/http/documentation#auth-token-revoke

Files

copy($from_path, $to_path)

my $result = $dropbox->copy($from_path, $to_path);

https://www.dropbox.com/developers/documentation/http/documentation#files-copy

copy_reference_get($path)

Get a copy reference to a file or folder. This reference string can be used to save that file or folder to another user's Dropbox by passing it to copy_reference/save.

my $result = $dropbox->copy_reference_get($path);

https://www.dropbox.com/developers/documentation/http/documentation#files-copy_reference-get

copy_reference_save($copy_reference, $path)

https://www.dropbox.com/developers/documentation/http/documentation#files-list_folder-continue

list_folder_get_latest_cursor($path [, \%optional_params])

A way to quickly get a cursor for the folder's state. Unlike list_folder, list_folder/get_latest_cursor doesn't return any entries. This endpoint is for app which only needs to know about new files and modifications and doesn't need to know about files that already exist in Dropbox.

my $result = $dropbox->list_folder_get_latest_cursor($path);

my $result = $dropbox->list_folder_get_latest_cursor($path, {

list_folder_longpoll($cursor [, \%optional_params])

A longpoll endpoint to wait for changes on an account. In conjunction with list_folder/continue, this call gives you a low-latency way to monitor an account for file changes. The connection will block until there are changes available or a timeout occurs. This endpoint is useful mostly for client-side apps. If you're looking for server-side notifications, check out our webhooks documentation.

my $result = $dropbox->list_folder_longpoll($cursor);

});

upload_session_start($content [, \%optional_params])

Upload sessions allow you to upload a single file using multiple requests. This call starts a new upload session with the given data. You can then use upload_session/append_v2 to add more data and upload_session/finish to save all the data to a file in Dropbox.

A single request should not upload more than 150 MB of file contents.

# File Handle
my $content = IO::File->new('./access.log', '<');

$dropbox->upload_session_start($content);

$dropbox->upload_session_start($content, {
    close => JSON::true
});

https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-start

my $result = $dropbox->upload_session_append_v2($content, {
    cursor => {
        session_id => $session_id,
        offset => $offset
    },
    close => JSON::true
});

https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-append_v2

upload_session_finish($content, $params)

    cursor => {
        session_id => $session_id,
        offset => $offset
    },
    commit => {
        path => '/Homework/math/Matrices.txt',
        mode => 'add',
