Plone support for HTTP verbs.

Project description

Plone REST

Purpose

plone.rest allows you to use HTTP verbs such as GET, POST, PUT, DELETE, etc. in Plone.

REST stands for Representational State Transfer. It is a software architectural principle to create loosely coupled web APIs.

plone.rest provides the basic infrastructure that allows us to build RESTful endpoints in Plone.

The reason for separating this infrastructure into a separate package from the ‘main’ full Plone REST API is so you can create alternative endpoints tailored to specific usecases. A number of these specific end points are already in active use.

Audience

plone.rest is for experienced web developers who want to build their own endpoints on top of Plone.

If you want to use a ready-made full RESTful Plone API, you should use plone.restapi. That package uses, and depends upon, this one.

Features

plone.rest currently supports the following HTTP verbs:

  • GET

  • POST

  • PUT

  • DELETE

  • PATCH

  • OPTIONS

Those verbs can be registered for Dexterity content objects and the Plone site root. The only format that is currently supported via HTTP content negotiation is ‘application/json’.

Registering RESTful Service Endpoints

plone.rest allows you to register HTTP verbs for Plone content with ZCML.

This is how you would register a PATCH request on Dexterity content:

<plone:service
  method="PATCH"
  for="plone.dexterity.interfaces.IDexterityContent"
  factory=".service.Patch"
  />

You have to specify the HTTP verb (GET, POST, PUT, DELETE, HEAD, OPTIONS), the interface for the content objects and the factory class that actually returns the content.

The factory class needs to inherit from the plone.rest ‘Service’ class and to implement a render method that returns a list or a dict:

from plone.rest import Service

class Patch(Service):

    def render(self):
        return {'message': 'PATCH: Hello World!'}

The return value (list or dict) will be automatically transformed into JSON.

Content Negotiation

To access the service endpoint we just created we have to send a GET request to a Dexterity object by setting the ‘Accept’ header to ‘application/json’:

PATCH /Plone/doc1 HTTP/1.1
Host: localhost:8080
Accept: application/json

The server then will respond with ‘200 OK’:

HTTP/1.1 200 OK
Content-Type: application/json

{
  'message': 'PATCH: Hello World!'
}

You can try this out on the command line:

$ http --auth admin:admin PATCH localhost:8080/Plone/doc1 Accept:application/json

Here is a list of examples for all supported HTTP verbs:

GET:

$ http --auth admin:admin GET localhost:8080/Plone/doc1 Accept:application/json

POST:

$ http --auth admin:admin POST localhost:8080/Plone/doc1 Accept:application/json

PUT:

$ http --auth admin:admin PUT localhost:8080/Plone/doc1 Accept:application/json

DELETE:

http --auth admin:admin DELETE localhost:8080/Plone/doc1 Accept:application/json

PATCH:

http --auth admin:admin PATCH localhost:8080/Plone/doc1 Accept:application/json

OPTIONS:

http --auth admin:admin OPTIONS localhost:8080/Plone/doc1 Accept:application/json

Installation
