Kong Ext Auth

Kong plugin to authenticate requests using external HTTP service.

Description

This plugin lets you authenticate any request using a separate HTTP service.

For every incoming request, the method, path, query and headers are forwarded to the auth service (removing the body).

If the service returns 200, the token in the body of the response (json) is retrieved and returned as the header (Authorization, bearer token) of the main request which continues its normal path. In any other case, 401 (Unauthorized) is returned to the client.

Installation

$ luarocks install kong-ext-auth

Update the plugins config to add kong-ext-auth:

plugins = bundled,kong-ext-auth

Configuration

$ curl -X POST http://kong:8001/services/{service}/plugins \

  -d 'config.path=/'
