Object storage plugin for CakePHP

This plugin offers an implementation of an object storage for CakePHP applications.

Features

This plugin provides:

• migration for creating the files table
• entity and table classes for Files model
• REST controller
• default routing
• service provider for the storage service using CakePHP's service container
• event listener to inject the service container in table instance on initialization
• modeless forms to handle file operations
• shell command to cleanup incomplete multipart uploads

Installation

You can install this plugin using composer:

To use AWS S3 as a backend storage, the SDK is also needed:

Usage

Add the plugin in your Application.php bootstrap:

Run the migration to create the files table:

Add the configuration for the backend storage in your app.php:

See chialab/php-object-storage library's README for more information on the adapters.

Disable routing

Use ['routes' => false] when adding the plugin to implement your own routes. You can still use Chialab/CakeObjectStorage.Files as controller if you only want to change the paths, or implement your own controller.

Disable event listener

Use ['bootstrap' => false] when adding the plugin to disable automatically adding the event listener. If you're using the plugin's FilesTable, you are required to set the DI container to its instances, or implement your own service handling.

Disable service provider

Use ['services' => false] when adding the plugin to disable automatically adding the storage service provider. You are required to provide a MultipartUploadInterface implementation to FilesTable instances, or implement your own service handling.

Upload

See File::getMultipartChunkSize() for the threshold between small file and multipart upload.

Create file entity

The default controller accepts a request like the following:

The response is like the following:

The file entity in the response has a property is_multipart to let the client know if a multipart upload is required. In this case, the response will also contain a chunk_size property with the maximum file part size, and a finalize URL to call after all parts have been uploaded.

Upload file

To upload the file, make a request like the following with the file as body:

Multipart upload

To upload a part of a multipart upload, add the part query parameter to the request:

The parameter is an incremental number starting from 1, which represent the "index" of the part currently uploading.

The endpoint will respond with a hash of the uploaded part that needs to be stored to finalize the upload later:

To finalize the upload:

To abort a multipart upload:
