The REST Server provides an interface for the Services module to communicate with REST clients.

REST Server 2.x

This is a brief introduction to how the rest server works. See the [services_oop][services_oop] module to find out more about how you easily can expose functionality in a resource-oriented way.
Controllers
-------------------
Tabulation of the controller mapping for the REST server. Requests gets mapped to different controllers based on the HTTP method used and the number of parts in the path.
Count refers to the number of path parts that comes after the path that identifies the resource type. The request for `/services/rest/node/123` would have the count 1, as `/services/rest/node` identifies the resource.
    X = CRUD
    A = Action
    T = Targeted action
    R = Relationship request
    COUNT |0|1|2|3|4|N|
    -------------------
    GET   |X|X|R|R|R|R|
    -------------------
    POST  |X|A|T|T|T|T|
    -------------------
    PUT   | |X| | | | |
    -------------------
    DELETE| |X| | | | |
    -------------------
CRUD
-------------------
The basis of the REST server.
    Create:   POST /services/rest/node + body data
    Retrieve: GET /services/rest/node/123
    Update:   PUT /services/rest/node/123 + body data
    Delete:   DELETE /services/rest/node/123
And last but least, the little bastard sibling to Retrieve that didn't get it's place in the acronym:
    Index:    GET /services/rest/node
In the REST server the index often doubles as a search function. The comment resource allows queries like the following for checking for new comments on a node (where 123456 is the timestamp for the last check and 123600 is now):
    New comments: GET /services/comment?nid=123&timestamp=123456:
    Comments in the last hour: GET /services/comment?timestamp=120000:123600
Actions
-------------------
Actions are performed directly on the resource type, not a individual resource. The following example is hypothetical (but plausible). Say that you want to expose a API for the [apachesolr][apachesolr] module. One of the things that could be exposed is the functionality to reindex the whole site.
    Publish:  POST /services/rest/apachesolr/reindex
Targeted actions
-------------------
Targeted actions acts on a individual resource. A good, but again - hypothetical, example would be the publishing and unpublishing of nodes.
    Publish:  POST /services/rest/node/123/publish
Relationships
-------------------
Relationship requests are convenience methods (sugar) to get something thats related to a individual resource. A real example would be the relationship that the [comment_resource][comment_resource] module adds to the node resource:
    Get comments: GET /services/rest/node/123/comments
This more or less duplicates the functionality of the comment index:
    Get comments: GET /services/rest/comments?nid=123

REST Server 1.x

REST can use either GET or POST values, so if you request:

http://www.example.com/services/rest?method=node.load&nid=1&fields=title,body

... You will be returned the title and body of node 1 in a format that REST clients could understand. The same goes for parameters that are passed through by POST. The key here is that you request method as the service to call, and pass all the parameters as their own names.

Requirements

Drupal 7

Note that the Drupal 7 port of the REST Server is already packaged with the Services module.
