ownCloud ONLYOFFICE integration app
This app enables users to edit office documents from ownCloud using ONLYOFFICE Document Server. Currently the following document formats can be edited with this app: csv, docx, pptx, txt, xlsx. The above mentioned formats are also available for viewing together with djvu, pdf, xps. The edited files of the corresponding type can be converted into the Office Open XML formats: doc, dot, dotm, dotx, epub, fodp, fods, fodt, htm, html, odp, odt, pot, potm, potx, pps, ppsm, ppsx, ppt, pptm, rtf, xls, xlsm, xlsx, xlt, xltm, xltx.
The app will create an item in the new (+) menu to create Document, Spreadsheet, Presentation. It will also create a new Open in ONLYOFFICE menu option within the document library for Office documents. This allows multiple users to collaborate in real time and to save back those changes to ownCloud.
You can also use our Docker installation to get installed and configured Document Server and ownCloud installation with a couple of commands.
Tested with ownCloud 9 and 10, the latest connector signed versions are available in the official store for ownCloud.
Installing ONLYOFFICE Document Server
You will need an instance of ONLYOFFICE 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). If that is not the case, use the official ONLYOFFICE Document Server documentation page: Document Server for Linux. ONLYOFFICE Document Server must also be able to POST to ownCloud directly.
Starting with version 4.3.0, ONLYOFFICE Document Server and ownCloud can be installed either on different computers, or on the same machine. In case you select the latter variant, you will need to set up a custom port for Document Server as by default both ONLYOFFICE Document Server and ownCloud work on port 80. Or you can use Document Server behind a proxy, please refer to this article to learn how you can configure it.
The easiest way to start an instance of ONLYOFFICE Document Server is to use Docker.
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. To start using ONLYOFFICE Document Server with ownCloud, the following steps must be performed:
Configuring ownCloud ONLYOFFICE integration app
In ownCloud open thepage 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
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:
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.
Then ONLYOFFICE Document Server downloads the document from ownCloud and the user begins editing.
ONLYOFFICE Document Server sends a POST request to the callback URL 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 callback URL 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.
