Introduction

Weimarnetz Registrator is a RESTful microservice for managing node number in our network. See https://wireless.subsignal.org/index.php?title=IP-System for more details.

Overview

HTTP verbs

Weimarnetz Registrator tries to adhere as closely as possible to standard HTTP and REST conventions in its use of HTTP verbs. To also support simple solutions like wget we wrap some verbs in GET requests.

Verb Usage

GET

Used to retrieve a resource

POST

Used to create a new resource

PUT

Used to update an existing resource, full updates only

DELETE

Used to delete an existing resource

HTTP status codes

Weimarnetz Registrator tries to adhere as closely as possible to standard HTTP and REST conventions in its use of HTTP status codes.

Status code Usage

200 OK

Standard response for successful HTTP requests.

The actual response will depend on the request method used.

In a GET request, the response will contain an entity corresponding to the requested resource.

In a POST request, the response will contain an entity describing or containing the result of the action.

201 Created

The request has been fulfilled and resulted in a new resource being created.

303 See other

400 Bad Request

The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

401 Unauthorized

404 Not Found

Time

Just returns the current server time.
