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,

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

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);

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);

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

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

upload_session_append_v2($content, $params)

Append more data to an upload session.

When the parameter close is set, this call will close the session.

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

# File Handle
my $content = IO::File->new('./access.log.1', '<');

my $result = $dropbox->upload_session_append_v2($content, {
    cursor => {
        session_id => $session_id,

    cursor => {
        session_id => $session_id,
        offset => $offset
    },
    commit => {
        path => '/Homework/math/Matrices.txt',
        mode => 'add',
        autorename => JSON::true,
        mute => JSON::false
    }
});

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

Users

get_account($account_id)

Get information about a user's account.

my $result = $dropbox->get_account($account_id);

https://www.dropbox.com/developers/documentation/http/documentation#users-get_account

get_account_batch(\@account_ids)

Get information about multiple user accounts. At most 300 accounts may be queried per request.

my $result = $dropbox->get_account_batch($account_ids);

https://www.dropbox.com/developers/documentation/http/documentation#users-get_account_batch

get_current_account()

Get information about the current user's account.

my $result = $dropbox->get_current_account;

https://www.dropbox.com/developers/documentation/http/documentation#users-get_current_account

get_space_usage()

Get the space usage information for the current user's account.

my $result = $dropbox->get_space_usage;

https://www.dropbox.com/developers/documentation/http/documentation#users-get_space_usage

Sharing

Create a shared link with custom settings. If no settings are given then the default visibility is RequestedVisibility.public (The resolved visibility, though, may depend on other aspects such as team and shared folder settings).

my $result = $dropbox->create_shared_link_with_settings($path, $settings);

https://www.dropbox.com/developers/documentation/http/documentation#sharing-create_shared_link_with_settings

list_shared_links($path)

List shared links of this user. If no path is given, returns a list of all shared links for the current user. For members of business teams using team space and member folders, returns all shared links in the team member's home folder unless the team space ID is specified in the request header. For more information, refer to the Namespace Guide. If a non-empty path is given, returns a list of all shared links that allow access to the given path - direct links to the given path and links to parent folders of the given path. Links to parent folders can be suppressed by setting direct_only to true.

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

https://www.dropbox.com/developers/documentation/http/documentation#sharing-list_shared_links

Modify the shared link's settings. If the requested visibility conflict with the shared links policy of the team or the shared folder (in case the linked file is part of a shared folder) then the LinkPermissions.resolved_visibility of the returned SharedLinkMetadata will reflect the actual visibility of the shared link and the LinkPermissions.requested_visibility will reflect the requested visibility.

my $result = $dropbox->modify_shared_link_settings($path, $settings, $remove_expiration);

https://www.dropbox.com/developers/documentation/http/documentation#sharing-modify_shared_link_settings

revoke_shared_link($url)

Revoke a shared link. Note that even after revoking a shared link to a file, the file may be accessible if there are shared links leading to any of the file parent folders. To list all shared links that enable access to a specific file, you can use the list_shared_links with the file as the ListSharedLinksArg.path argument.

my $result = $dropbox->revoke_shared_link($url);

https://www.dropbox.com/developers/documentation/http/documentation#sharing-revoke_shared_link
