README

An Amazon S3 component for Yii2.

Yii2 AWS S3 uses SemVer.

Version 2.x requires PHP 7. For PHP less 7.0 use 1.x.

Installation

1. Run the Composer command to install the latest version:

   composer require frostealth/yii2-aws-s3 ~2.0

2. Add the component to config/main.php

   'components' => [
       // ...
       's3' => [
           'class' => 'frostealth\yii2\aws\s3\Service',
           'credentials' => [ // Aws\Credentials\CredentialsInterface|array|callable
               'key' => 'my-key',
               'secret' => 'my-secret',
           ],
           'region' => 'my-region',
           'defaultBucket' => 'my-bucket',
           'defaultAcl' => 'public-read',
       ],
       // ...
   ],

Basic usage

Usage of the command factory and additional params

/** @var \frostealth\yii2\aws\s3\Service $s3 */
$s3 = Yii::$app->get('s3');

/** @var \Aws\ResultInterface $result */
$result = $s3->commands()->get('filename.ext')->saveAs('/path/to/local/file.ext')->execute();

$result = $s3->commands()->put('filename.ext', 'body')->withContentType('text/plain')->execute();

$result = $s3->commands()->delete('filename.ext')->execute();

$result = $s3->commands()->upload('filename.ext', '/path/to/local/file.ext')->withAcl('private')->execute();

$result = $s3->commands()->restore('filename.ext', $days = 7)->execute();

$result = $s3->commands()->list('path/')->execute();

/** @var bool $exist */
$exist = $s3->commands()->exist('filename.ext')->execute();

/** @var string $url */
$url = $s3->commands()->getUrl('filename.ext')->execute();

/** @var string $signedUrl */
$signedUrl = $s3->commands()->getPresignedUrl('filename.ext', '+2 days')->execute();

Short syntax

/** @var \frostealth\yii2\aws\s3\Service $s3 */
$s3 = Yii::$app->get('s3');

/** @var \Aws\ResultInterface $result */
$result = $s3->get('filename.ext');

$result = $s3->put('filename.ext', 'body');

$result = $s3->delete('filename.ext');

$result = $s3->upload('filename.ext', '/path/to/local/file.ext');

$result = $s3->restore('filename.ext', $days = 7);

$result = $s3->list('path/');

/** @var bool $exist */
$exist = $s3->exist('filename.ext');

/** @var string $url */
$url = $s3->getUrl('filename.ext');

/** @var string $signedUrl */
$signedUrl = $s3->getPresignedUrl('filename.ext', '+2 days');

Asynchronous execution

/** @var \frostealth\yii2\aws\s3\Service $s3 */
$s3 = Yii::$app->get('s3');

/** @var \GuzzleHttp\Promise\PromiseInterface $promise */
$promise = $s3->commands()->get('filename.ext')->async()->execute();

$promise = $s3->commands()->put('filename.ext', 'body')->async()->execute();

$promise = $s3->commands()->delete('filename.ext')->async()->execute();

$promise = $s3->commands()->upload('filename.ext', 'source')->async()->execute();

$promise = $s3->commands()->list('path/')->async()->execute();

Advanced usage

/** @var \frostealth\yii2\aws\s3\interfaces\Service $s3 */
$s3 = Yii::$app->get('s3');

/** @var \frostealth\yii2\aws\s3\commands\GetCommand $command */
$command = $s3->create(GetCommand::class);
$command->inBucket('my-another-bucket')->byFilename('filename.ext')->saveAs('/path/to/local/file.ext');

/** @var \Aws\ResultInterface $result */
$result = $s3->execute($command);

// or async
/** @var \GuzzleHttp\Promise\PromiseInterface $promise */
$promise = $s3->execute($command->async());

Custom commands

Commands have two types: plain commands that's handled by the PlainCommandHandler and commands with their own handlers. The plain commands wrap the native AWS S3 commands.

The plain commands must implement the PlainCommand interface and the rest must implement the Command interface. If the command doesn't implement the PlainCommand interface, it must have its own handler.

Every handler must extend the Handler class or implement the Handler interface. Handlers gets the S3Client instance into its constructor.

The implementation of the HasBucket and HasAcl interfaces allows the command builder to set the values of bucket and acl by default.

To make the plain commands asynchronously, you have to implement the Asynchronous interface. Also, you can use the Async trait to implement this interface.

Consider the following command:

<?php

namespace app\components\s3\commands;

use frostealth\yii2\aws\s3\base\commands\traits\Options;
use frostealth\yii2\aws\s3\interfaces\commands\Command;
use frostealth\yii2\aws\s3\interfaces\commands\HasBucket;

class MyCommand implements Command, HasBucket
{
    use Options;

    protected $bucket;

    protected $something;

    public function getBucket()
    {
        return $this->bucket;
    }

    public function inBucket(string $bucket)
    {
        $this->bucket = $bucket;

        return $this;
    }

    public function getSomething()
    {
        return $this->something;
    }

    public function withSomething(string $something)
    {
        $this->something = $something;

        return $this;
    }
}

The handler for this command looks like this:

<?php

namespace app\components\s3\handlers;

use app\components\s3\commands\MyCommand;
use frostealth\yii2\aws\s3\base\handlers\Handler;

class MyCommandHandler extends Handler
{
    public function handle(MyCommand $command)
    {
        return $this->s3Client->someAction(
            $command->getBucket(),
            $command->getSomething(),
            $command->getOptions()
        );
    }
}

And usage this command:

/** @var \frostealth\yii2\aws\s3\interfaces\Service */
$s3 = Yii::$app->get('s3');

/** @var \app\components\s3\commands\MyCommand $command */
$command = $s3->create(MyCommand::class);
$command->withSomething('some value')->withOption('OptionName', 'value');

/** @var \Aws\ResultInterface $result */
$result = $s3->execute($command);

Custom plain command looks like this:

<?php

namespace app\components\s3\commands;

use frostealth\yii2\aws\s3\interfaces\commands\HasBucket;
use frostealth\yii2\aws\s3\interfaces\commands\PlainCommand;

class MyPlainCommand implements PlainCommand, HasBucket
{
    protected $args = [];

    public function getBucket()
    {
        return $this->args['Bucket'] ?? '';
    }

    public function inBucket(string $bucket)
    {
        $this->args['Bucket'] = $bucket;

        return $this;
    }

    public function getSomething()
    {
        return $this->args['something'] ?? '';
    }

    public function withSomething($something)
    {
        $this->args['something'] = $something;

        return $this;
    }

    public function getName(): string
    {
        return 'AwsS3CommandName';
    }

    public function toArgs(): array
    {
        return $this->args;
    }
}

Any command can extend the ExecutableCommand class or implement the Executable interface that will allow to execute this command immediately: $command->withSomething('some value')->execute();.
