Flysystem Webdav service provider for Laravel 5

What is it for?

That is a ready-to-use service provider for flysystem-webdav

Why i need that?

You don't need that for sure, you can change service provider by yourself whatever you like (with installed flysystem-webdav)

Okay, I'm quite lazy guy, how to install this solution?

Now you have to be patient. It takes a couple minutes.

• This is nginx-related solution (if someone ready to test Apache or lighttpd or etc. - welcome, let's extend description), so we have to set up nginx at first

sudo apt-get install nginx nginx-common nginx-extras

• Set up nginx webdav host at first.

v1. Host for webdav server

server {
  # ssl
  #listen 443;
  #ssl on;
  #ssl_certificate      /path/to/pem/file.pem;
  #ssl_certificate_key  /path/to/key/file.key;

  listen 80;
  server_name host.name.com;

  location / {
    limit_except GET {
      auth_basic "Auth";
      auth_basic_user_file /path/to/htpasswd/file/.htpasswd;
    }

    # root folder
    root /path/to/webdav/root;
    # max upload file size 
    client_max_body_size 100m;
    # chmod for uploaded files
    dav_access group:rw all:r;
    # methods for upload
    dav_methods PUT DELETE MKCOL COPY MOVE;
    dav_ext_methods PROPFIND OPTIONS;
    # create full file path on upload (no need to create folders)
    create_full_put_path on;
    # autoindex for webdav
    autoindex off;
    autoindex_exact_size off;
    autoindex_localtime on;
    charset utf-8;
  }
}

Here we have nginx config (v1) for webdav host without subfolder for upload. Create path whatever you like from root. For all http requests that is not GET type, service user have to be authorized (limit_except directive).

REM

If you have never used .htpasswd before, you have to install apache utils

sudo apt-get install apache2-utils

And then go to manual page

v2. Host for webdav server with subfolder

server {
  # ssl
  #listen 443;
  #ssl on;
  #ssl_certificate      /path/to/pem/file.pem;
  #ssl_certificate_key  /path/to/key/file.key;

  listen 80;
  server_name host.name.com;

  location / {
    root /path/to/webdav/root/or/another/folder;
  }

  location /upload {
    limit_except GET {
      auth_basic "Auth";
      auth_basic_user_file /path/to/htpasswd/file/.htpasswd;
    }

    # root folder
    root /path/to/webdav/root;
    # max upload file size 
    client_max_body_size 100m;
    # chmod for uploaded files
    dav_access group:rw all:r;
    # methods for upload
    dav_methods PUT DELETE MKCOL COPY MOVE;
    dav_ext_methods PROPFIND OPTIONS;
    # create full file path on upload (no need to create folders)
    create_full_put_path on;
    # autoindex for webdav
    autoindex off;
    autoindex_exact_size off;
    autoindex_localtime on;
    charset utf-8;
  }
}

Here we have nginx config (v2) for webdav host with subfolder for upload. Create path whatever you like from subfolder (upload folder name is not needed, change that if you like).

• Now we have to create folder for webdav service with same access rights as nginx have

mkdir /path/to/webdav/root
chown -R www-data:www-data /path/to/webdav/root

• Ok, now test your nginx config and restart when ready

sudo nginx -t
sudo nginx -s relaod

• We've done with nginx, let's get deal with PHP side. Let's install this module for your Laravel app.

composer require ijin82/flysystem-webdav

• Now we have to set up service provider. Open your config/app.php and add new provider to providers section.

return [
    //...
    'providers' => [
        //...
        Ijin82\Flysystem\Webdav\WebdavServiceProvider::class,
        //...
    ],
    //...
];

• Let's configure new filesystem. Open your config/filesystems.php and add new fs config like this.

return [
    //...
    'avatars' => [
        'driver' => 'webdav',
        'baseUri' => 'http://host.name.com',
        'path_prefix' => 'avatar/',
        'path_alias' => '',
        'userName' => 'webdav_user_login',
        'password' => 'webdav_user_password',
    ],
    //...
];

For sure, you have to use env hepler for config, here is just an example config without it, just fyi.
Example description:

• driver - new webdav driver (check service provider source code)
• baseUri - your webdav host name
• path_prefix - files folder prefix. If you plan to upload files for nginx config v2, then you have to prefix your folder name with upload folder name, meaning upload/avatar/ for v2 nginx config, and simply avatar/ for v1 config, because this parameter using for file upload and in v2 config we have to hit upload folder according to your nginx config.
• path_alias - OPTIONAL parameter, in case if you like to access your upladed files by short path, for example your original upload prefix is upload/client/avatars/ and you want client-side file path looks like /av/file1.jpg. Then you have to create symlink from upload/client/avatars/ to av/ folder on your server (under your nginx root) and set up path_alias parameter as av/. By default, your path_prefix parameter will be user for uri generation.
• userName - user name from your .htpasswd used for file upload
• password - user password from your .htpasswd used for file upload

Upload example

public function avatarUpload(Request $request)
{
    //...
    $file = $request->file('avatar_file');
    //... check file type, build name, save name in DB, whatever you like
    $fileName = $file->getClientOriginalName(); // for example
    // https://laravel.com/docs/5.5/requests#storing-uploaded-files
    $file->storeAs('subfolder-name-or-empty', $fileName, ['disk' => 'avatars']);
    //...
    // save file name or logic to build that
    //...
}

Get file url, blade example

<a href="{{ Storage::disk('avatars')->url($fileName) }}" target="_blank">.{{ $ext }}</a>

Get file url, code example

//... fileName logic
$fileUrl = Storage::disk('avatars')->url($fileName);

Delete file example

Storage::disk('avatars')->delete($fileName);

Delete folder example

// WARNING, all files inside that also will be deleted
Storage::disk('avatars')->deleteDir('dir-name/or/path');
