org.chenile.core.interceptors.ValidateCopyHeaders

All Implemented Interfaces:

Command<ChenileExchange>

public class ValidateCopyHeaders
extends BaseChenileInterceptor

As per HTTP convention, all custom headers start with "x-" This interceptor copies all headers that start with "x-" into the context. The context can then be used to read the values by subsequent interceptors and other classes. If headers start with x-p- then they are considered protected. This means that they cannot be passed from the outside by the requester. Attempts to pass them will result in a security exception. This is because we consider such requests as attempts to hack the system. These internal headers will need to be pushed into the system by subsequent interceptors. Please see chenile headers for more details.

Method Details

doPreProcessing

protected void doPreProcessing(ChenileExchange exchange)

Description copied from class: BaseChenileInterceptor

Override this to do pre-processing. This will be called before the service is invoked. Don't expect to see exception or response being set in ChenileExchange. However you can check for ChenileExchange.getBody() to manipulate the body if this interceptor is a Chenile post processor or a service specific or operation specific interceptor.
If this interceptor is a Chenile pre-processor, then ChenileExchange.getBody() will return null. Then you need to look at headers only.

Overrides:

doPreProcessing in class BaseChenileInterceptor

doPostProcessing

protected void doPostProcessing(ChenileExchange exchange)

Description copied from class: BaseChenileInterceptor

Override this to do post processing. This will be called even if there is an exception downstream. So make sure that if you don't want to do any processing in case of exception, check if ChenileExchange.getException() returns null value. If you happen to throw an exception in this method, it will get added to the set of errors that would ultimately be returned. See also ChenileExchange.setException(Throwable)

Overrides:

doPostProcessing in class BaseChenileInterceptor

Parameters:

exchange - Chenile Exchange
