The problem

Every web project have different binary data to host and handle: images, PDFs, etc. In most cases those files should be converted in different ways:

• images: resize and format
• PDF to image
• Open office templates to MS Office documents and PDFs

Solution

This application can host a binary/text data (Documents) of a particular content type and convert it in requested way.

It intended to be deployed at separate hostname as bin.project-hostname. Also it is recommended to use cookieless domain for read-only serving of public content.

Installation

composer install
./phpunit

Usage

We desided to use REST interface. Here are the commands.

POST

Submitting data to the service.

Url: /
Data: Document and (optionally) variables to parse if Document is a template
Return: {id : "_auto_generated_id_string_", contentType: "_content_type_",
    ext: "_standart_file_extension_", length: _file_size_, filename: "_original_file_name_"}

GET

Getting a document.

Url: /_id_string_._ext_
Data: no
Return: Document

Example: /12wkr234ser349.pdf - get document "12wkr234ser349" as PDF

Getting a document related to some restricted group

Url: /_auth_group_3_letters_/_id_string_._ext_
Data: no
Return: Document

Example: /adm/6b12YX.pdf - get document "12wkr234ser349" as PDF

Restriction of /adm/* URIs should be done externally. See section Authorization below.

DELETE

Deleting a document.

Url: /_id_string_
Data: no
Return: {}
