This is the WebDAV interface. It can only be accessed by WebDAV clients such as the ownCloud desktop sync client

falinhares72 · March 9, 2018, 6:05pm

I am having problems to access the Owncloud server WebDav through my browser. After I provide the address

http://IPADDRESS/owncloud/remote.php/dav/files/USERID/

I get the following message:

"This is the WebDAV interface. It can only be accessed by WebDAV clients such as the ownCloud desktop sync client."

Steps to reproduce

Install Owncloud 10.0.7 on a Ubuntu 16.0.4 Server
Connect a Oncloud Desktop Client with success
Log into the account and try o access the webdav through browser

Expected behaviour

I should be able to access the folder through the webdav with no problems

Actual behaviour

I get the message that I can only access WebDAV through a client

I think this message is showing you the reason why you're facing this issue. A browser is probably no WebDAV client, curl probably isn't one as well if not correctly used.

I thnik I did right because when I activated the debug function to track the problem, I was able to read correctly from webdav... but with the side effect that I was not able to download any file, not even from the owncloud official pages.

When I removed the debug function from the config.php I lost the access to the folder contents and got back the access to the files.

One another thing that I noticed from this 10.0.7 version is that the link to download a file was kept like the version 8:

http://SERVER/owncloud/remote.php/webdav/FOLDER/FILE

but to access the folder the link is different:

http://SERVER/owncloud/remote.php/dav/files/USER/FOLDER

I think the posted logentry shows again some info / pointers whats missing in your request:

falinhares72 · March 12, 2018, 11:02pm

The question is: what is missing? I've checked all my installation and found nothing so far.

DeepDiver1975 · March 12, 2018, 11:16pm

To access ownCloud via WebDav you need to use a WebDav client - e.g. cadaver.

The reason you see something in the browser in debug mode is that we add a simple but powerfull development tool which acts on top of webdav.

Maybe you explain what you are trying to do and we can find a solution.

falinhares72 · March 12, 2018, 11:21pm

I have a PHP system that uses Owncloud as a storage device. I use the system to upload/download files e show folders. So far I was using owncloud 8 at windows. Now I am trying to setup this cloud on linux/ubuntu using owncloud 10.0.7. This is my first try on using Linux. I`ve followed a guide to install owncloud and everything went fine. including setting up an owncloud client to sync files. The problem is when I use CURL at PHP to retrieve the contents of a folder. I get this message that " It can only be accessed by WebDAV clients such as the ownCloud desktop sync client." and when I set the debug on, it goes away.

DeepDiver1975 · March 12, 2018, 11:26pm

Then use the sabredav library which ships a WebDav client for php. This way you can talk proper WebDav.

see http://sabre.io/dav/davclient/

falinhares72 · March 12, 2018, 11:27pm

I am using the sabredav library

DeepDiver1975 · March 12, 2018, 11:28pm

But in all the messages above you are talking about curl and browser - this does not fit together.

falinhares72 · March 12, 2018, 11:33pm

Curl gives me the same result as the browser. Using the browser to test the sabredav is better than the code. First I thought that was something wrong in the code that works with owncloud 8 and it was not working with owncloud 10, then I found out that the problem its not with the code but with the owncloud 10 server.

DeepDiver1975 · March 12, 2018, 11:40pm

FYI: using curl to download a file via old and new webdav endpoint - maybe this helps ...
Listing folder content requires a PROPFIND request - best to be executed with a WebDav client or library

falinhares72 · March 12, 2018, 11:44pm

I am away from the desktop I use to code. Tomorrow I'll post the code used for owncloud 8 (that works) and with owncloud 10 (only works in debug mode). I do not believe the problem is with the code. I believe I missed something on the server install/config.

falinhares72 · March 13, 2018, 11:29am

Here it's the code that works on accessing a folder from owncloud8

include_once 'vendor/autoload.php';
$settings = array(
	'baseUri' => 'http://'.$GLOBALS['server_owncloud'].'/owncloud/remote.php/webdav/'.$url,
	'userName' => $GLOBALS['user_owncloud'],
	'password' => $GLOBALS['pass_owncloud'],
);               
ini_set('memory_limit', '-1');
$client1 = new Sabre\DAV\Client($settings);
$response = $client1->request('GET');

The owncloud10 code is slightly different only on the baseUri:

include_once 'vendor/autoload.php';
$settings = array(
	'baseUri' => 'http://'.$GLOBALS['server_owncloud'].'/owncloud/remote.php/dav/files/'.$GLOBALS['user_owncloud'].'/'.$url,
	'userName' => $GLOBALS['user_owncloud'],
	'password' => $GLOBALS['pass_owncloud'],
);               
ini_set('memory_limit', '-1');
$client1 = new Sabre\DAV\Client($settings);
$response = $client1->request('GET');

when I run the owncloud10 code without debug=true I get this $response:

Making progress. I was able to access the folder using propfind:

Now I am trying to put this code on PHP but got nothing as result:

include_once 'vendor/autoload.php';
$url='http://cloud.apiceflow.com.br/owncloud/remote.php/dav/files/'.$GLOBALS['user_owncloud'].'/apice/';
$settings = array(
        'baseUri' => $url,
        'userName' => $GLOBALS['user_owncloud'],
        'password' => $GLOBALS['pass_owncloud'],
    );

$client = new Sabre\DAV\Client($settings);
$response = $client->propfind($url, array(
    '{DAV:}displayname',
    '{DAV:}getcontentlength',
));
var_dump($response);
