Class GraphApiErrorHandler

java.lang.Object

de.juplo.facebook.client.GraphApiErrorHandler

All Implemented Interfaces:

org.springframework.web.client.ResponseErrorHandler

public class GraphApiErrorHandler
extends Object
implements org.springframework.web.client.ResponseErrorHandler

Error-Handler for error-messages from the Facebook Graph-API.

This error-handler handels responses withe the HTTP-status code 400 BAD REQUEST. It tries to extract and parse the error-message from the HTTP-body. Successfully extracted and parsed messages are mapped to a hierarchy of exceptions, that reflects the hierarchy of the error- codes and -types.

If the HTTP-status-code of the response is not 400 BAD REQUEST or the HTTP-body could not be extracted or parsed, this error-handler delegates the handling to its parent.
