onlyoffice icon ownCloud ONLYOFFICE integration app

This app allows users to edit office documents from ownCloud using ONLYOFFICE Docs packaged as Document Server - Community or Enterprise Edition.

Features

The app allows to:

  • Create and edit text documents, spreadsheets, and presentations.
  • Share files with different permission types - viewing/editing, commenting, reviewing, filling forms. It's also possible to restrict downloading (in all editors) and modifying filters (in spreadshhets). Sharing via public link is also available.
  • Co-edit documents in real-time: use two co-editing modes (Fast and Strict), Track Changes, comments, and built-in chat. Co-editing is also available several federated ownCloud instances connected to one Document Server.

Supported formats:

  • For viewing and editing: DOCX, XLSX, PPTX, CSV, TXT.
  • For viewing only: PDF.
  • For converting to Office Open XML formats: DOC, DOCM, DOT, DOTX, EPUB, HTM, HTML, ODP, ODT, POT, POTM, POTX, PPS, PPSM, PPSX, PPT, PPTM, RTF, XLS, XLSM, XLT, XLTM, XLTX.

ODT, ODS, and ODP is also available for instant conversion. After you enable the corresponding option in the admin settings, ODF-formatted documents are immediately converted in the editor and opened after you click on it.

Installing ONLYOFFICE Docs

You will need an instance of ONLYOFFICE Docs (Document Server) that is resolvable and connectable both from ownCloud and any end clients (version 4.2.7 and later are supported for use with the app). ONLYOFFICE Document Server must also be able to POST to ownCloud directly.

ONLYOFFICE Document Server and ownCloud can be installed either on different computers, or on the same machine. If you use one machine, set up a custom port for Document Server as by default both ONLYOFFICE Document Server and ownCloud work on port 80.

You can install free Community version of ONLYOFFICE Docs or scalable Enterprise Edition with pro features.

To install free Community version, use Docker (recommended) or follow these instructions for Debian, Ubuntu, or derivatives.

To install Enterprise Edition, follow instructions here.

Community Edition vs Enterprise Edition comparison can be found here.

To use ONLYOFFICE behind a proxy, please refer to this article.

You can also use our Docker installation to install pre-configured Document Server (free version) and ownCloud with a couple of commands.

Installing ownCloud ONLYOFFICE integration app

The ownCloud administrator can install the integration app from the in-built application market. For that click the upper-left hamburger menu and select Market. After that find ONLYOFFICE in the list of available applications and install it.

If the server with the ownCloud installed does not have an Internet access, or if you need it for some other reason, the administrator can install the application manually:

  1. Go to the ownCloud server apps/ directory (or some other directory used):

    cd apps/
  2. Get the ownCloud ONLYOFFICE integration app. There are several ways to do that:

    a. Download the latest signed version from the official store for ownCloud.

    b. Or you can download the latest signed version from the application release page on GitHub.

    c. Or you can clone the application source code and compile it yourself:

    git clone https://github.com/ONLYOFFICE/onlyoffice-owncloud.git onlyoffice

    ownCloud does not work with unsigned applications giving an alert, so you will need to use either option a or b to get the application.

  3. Change the owner to update the application right from ownCloud web interface:

    chown -R www-data:www-data onlyoffice
  4. In ownCloud open the ~/settings/admin?sectionid=apps&category=disabled page with Not enabled apps by administrator and click Enable for the ONLYOFFICE application.

Configuring ownCloud ONLYOFFICE integration app

In ownCloud open the ~/settings/admin?sectionid=additional#onlyoffice page with administrative settings for ONLYOFFICE section. Enter the following address to connect ONLYOFFICE Document Server:

https://<documentserver>/

Where the documentserver is the name of the server with the ONLYOFFICE Document Server installed. The address must be accessible for the user browser and from the ownCloud server. The ownCloud server address must also be accessible from ONLYOFFICE Document Server for correct work.

Sometimes your network configuration might not allow the requests between installed ownCloud and ONLYOFFICE Document Server using the public addresses. The Advanced server settings allows to set the ONLYOFFICE Document Server address for internal requests from ownCloud server and the returning ownCloud address for the internal requests from ONLYOFFICE Document Server. You need to enter them in the appropriate fields.

To restrict the access to ONLYOFFICE Document Server and for security reasons and data integrity the encrypted signature is used. Specify the Secret key in the ownCloud administrative configuration. In the ONLYOFFICE Document Server config file specify the same secret key and enable the validation.

Enable or disable the Open file in the same tab setting.

The Open in ONLYOFFICE action will be added to the file context menu. You can specify this action as default and it will be used when the file name is clicked for the selected file types.

How it works

The ONLYOFFICE integration follows the API documented here:

  • When creating a new file, the user navigates to a document folder within ownCloud and clicks the Document, Spreadsheet or Presentation item in the new (+) menu.

  • The browser invokes the create method in the /lib/Controller/EditorController.php controller. This method adds the copy of the file from the assets folder to the folder the user is currently in.

  • Or, when opening an existing file, the user navigates to it within ownCloud and selects the Open in ONLYOFFICE menu option.

  • A new browser tab is opened and the index method of the /lib/Controller/EditorController.php controller is invoked.

  • The app prepares a JSON object with the following properties:

    • url - the URL that ONLYOFFICE Document Server uses to download the document;
    • callbackUrl - the URL that ONLYOFFICE Document Server informs about status of the document editing;
    • documentServerUrl - the URL that the client needs to respond to ONLYOFFICE Document Server (can be set at the administrative settings page);
    • key - the etag to instruct ONLYOFFICE Document Server whether to download the document again or not;
  • ownCloud takes this object and constructs a page from templates/editor.php template, filling in all of those values so that the client browser can load up the editor.

  • The client browser makes a request for the javascript library from ONLYOFFICE Document Server and sends ONLYOFFICE Document Server the DocEditor configuration with the above properties.

  • Then ONLYOFFICE Document Server downloads the document from ownCloud and the user begins editing.

  • ONLYOFFICE Document Server sends a POST request to the callbackUrl to inform ownCloud that a user is editing the document.

  • When all users and client browsers are done with editing, they close the editing window.

  • After 10 seconds of inactivity, ONLYOFFICE Document Server sends a POST to the callbackUrl letting ownCloud know that the clients have finished editing the document and closed it.

  • ownCloud downloads the new version of the document, replacing the old one.

Known issues

  • Adding the storage using the External storages app has issues with the co-editing in some cases. If the connection is made using the same authorization keys (the Username and password or Global credentials authentication type is selected), then the co-editing is available for the users. If different authorization keys are used (Log-in credentials, save in database or User entered, store in database authentication options), the co-editing is not available. When the Log-in credentials, save in session authentication type is used, the files cannot be opened in the editor.

  • ownCloud provides an option to encrypt the file storage. But if the encryption with the per-user encryption keys (used by default in ownCloud Default encryption module app) is enabled, ONLYOFFICE Document Server cannot open the encrypted files for editing and save them after the editing. The ONLYOFFICE section of the administrative settings page will display a notification about it. However if you set the encryption with the master key, ONLYOFFICE application will work as intended. The instruction on enabling master key based encryption is available in the official documentation on ownCloud websites.

  • If you are using a self-signed certificate for your Document Server, ownCloud will not validate such a certificate and will not allow connection to/from Document Server. This issue can be solved the following way: locate the ownCloud config file (/owncloud/config/config.php) and open it. Insert the following section to it:

    'onlyoffice' => array (
        'verify_peer_off' => true
    )

    This will disable the certificate verification and allow ownCloud to establish connection with Document Server, but you must remember that this is a temporary insecure solution and we strongly recommend that you replace the certificate with the one issued by some CA. Once you do that, do not forget to remove the above section from ownCloud config file.
