A set of factories to build Flysystem adapters from DSN strings, like:

  • s3://user:pass@endpoint?region=region&bucket=bucket
  • local://some/path
  • sftp://user@host:port/absolute/path?private_key=secret.pem
  • and more...

Installation

$ composer require webalternatif/flysystem-dsn

Because this package does not explicitely require inner adapters, you will have to composer require them yourself in your project.
See the adapters section to know how to install them.

Usage

use Webf\Flysystem\Dsn\AdapterFactory\AwsS3AdapterFactory;
use Webf\Flysystem\Dsn\AdapterFactory\FlysystemAdapterFactory;
use Webf\Flysystem\Dsn\AdapterFactory\OpenStackSwiftAdapterFactory;

$factory = new FlysystemAdapterFactory([
    new AwsS3AdapterFactory(),
    new OpenStackSwiftAdapterFactory(),
]);

$adapter = $factory->createAdapter($dsn);

Adapters

AWS S3

Inner adapter league/flysystem-aws-s3-v3
Install composer require league/flysystem-aws-s3-v3
Factory class Webf\Flysystem\Dsn\AdapterFactory\AwsS3AdapterFactory
DSN s3://username:password@endpoint?region=region&bucket=bucket
  • Use s3+http:// if the endpoint does not support https.
  • s3:// is equivalent to s3+https://.
  • username is the access key id.
  • password is the secret access key.

Optional DSN parameters

  • version (default: latest)

Failover

Inner adapter webalternatif/flysystem-failover-bundle
Install composer require webalternatif/flysystem-failover-bundle
Factory class Webf\Flysystem\Dsn\AdapterFactory\FailoverAdapterFactory
DSN failover(inner1:// inner2:// ...)?name=name
  • There must be at least two DSN arguments for the failover DSN function.
  • The name parameter is used for the failover adapter's name in the failover bundle (used to identify adapters in Symfony commands).
  • For each inner DSN, you can specify a time_shift parameter (see configuration section of the failover bundle for more info). This parameter is removed from the inner DSN when it's built.

Ftp

Inner adapter league/flysystem-ftp
Install composer require league/flysystem-ftp
Factory class Webf\Flysystem\Dsn\AdapterFactory\FtpAdapterFactory
DSN ftp://username:password@host:port/absolute/path
  • Port is optional and defaults to 21
  • If the path contains spaces, replace each one by %20.

Optional DSN parameters

  • ssl: whether to use ftp_ssl_connect instead of ftp_connect (default: false)
  • timeout: timeout for all network operations (default: 90)
  • utf8: whether to enable the UTF-8 mode or not (default: false)
  • passive: whether to enable the passive mode or not (default: true)
  • transfer_mode: transfer mode used for ftp_fget and ftp_fput calls (must be ascii or binary, default: binary)
  • system_type: system type of the ftp server (must be unix or windows)
  • ignore_passive_address: whether to set the FTP_USEPASVADDRESS option to the opposite
  • timestamps_on_unix_listings: whether to set last modified in metadata or not for unix systems (default: false)
  • recurse_manually: whether to recurse directories "manually" instead of using the FTP option when the $deep parameter of listContents() is set to true (default: false)
  • public_file_permission: unix permission for public files (default: 0644)
  • private_file_permission: unix permission for public files (default: 0600)
  • public_dir_permission: unix permission for public files (default: 0755)
  • private_dir_permission: unix permission for public files (default: 0700)
  • default_dir_visibility: default visibility for automatically created directories (must be public or private, default: private)

In memory

Inner adapter league/flysystem-memory
Install composer require league/flysystem-memory
Factory class Webf\Flysystem\Dsn\AdapterFactory\InMemoryAdapterFactory
DSN in-memory://

Optional DSN parameters

  • default_visibility: default visibility of created files and directories (must be public or private, default: public)

Lazy

This adapter allows deferring the creation of the inner adapter until it is actually used (i.e., when Flysystem's methods are called). This is useful when you don't want an adapter to be created, but you need to have it somewhere (e.g., in a service container), and the creation of the adapter is expensive (e.g., it makes a network request).

The drawback is that you have to make sure the DSN of the inner adapter is valid, otherwise an exception will be thrown at "usage" time.

Inner adapter Webf\Flysystem\Dsn\Adapter\LazyAdapter
Factory class Webf\Flysystem\Dsn\AdapterFactory\LazyAdapterFactory
DSN lazy(inner://)
  • There must be exactly one DSN argument for the lazy DSN function.

Local

Inner adapter Built-in with league/flysystem
Factory class Webf\Flysystem\Dsn\AdapterFactory\LocalAdapterFactory
DSN local://absolute_or_relative_path
  • If the path contains spaces, replace each one by %20.

Optional DSN parameters

  • public_file_permission: unix permission for public files (default: 0644)
  • private_file_permission: unix permission for public files (default: 0600)
  • public_dir_permission: unix permission for public files (default: 0755)
  • private_dir_permission: unix permission for public files (default: 0700)
  • default_dir_visibility: default visibility for automatically created directories (must be public or private, default: private)

OpenStack Swift

Inner adapter webalternatif/flysystem-openstack-swift
Install composer require webalternatif/flysystem-openstack-swift
Factory class Webf\Flysystem\Dsn\AdapterFactory\OpenStackSwiftAdapterFactory
DSN swift://username:password@endpoint?region=region&container=container
  • Use swift+http:// if the endpoint does not support https.
  • swift:// is equivalent to swift+https://.
  • username is optional if parameter user_id is present.
  • temp_url_key (see below) is required to be able to generate temporary URLs.

Optional DSN parameters

  • user_id: auth.identity.password.user.id value sent to Keystone v3 API
  • user_domain_id: auth.identity.password.user.domain.id value sent to Keystone v3 API (default: default if user_id and user_domain_name are not defined)

Tests

To run all tests, execute the command:

composer test

This will run Psalm, PHPUnit, Infection and a PHP-CS-Fixer check, but you can run them individually like this:

composer psalm
composer phpunit
composer infection
composer cs-check
