Error validating access token
The Java Script code then parses the response (line 5) and sends the appropriate status code back to the so that errors can be distinguished from invalid tokens.Note: This code is provided as a proof of concept only, and is not production quality.References to NGINX Plus apply only to that product.The standard method for validating access tokens with an Id P is called , is now a widely supported standard that describes a JSON/REST interface that a Relying Party uses to present a token to the Id P, and describes the structure of the response.In the real world, there are two formats in common usage: After authentication, a client presents its access token with each HTTP request to gain access to protected resources.
Typically, a JWT also includes an expiry date which can also be checked.
These are authentication credentials passed from client to API server, and typically carried as an HTTP header.
OAuth 2.0, however, is a maze of interconnecting standards.
This can become a significant issue when the Id P in question is a hosted solution or cloud provider.
NGINX and NGINX Plus can offer optimizations to this drawback by caching the introspection responses.
