-------------------------------------
Summary: If setting Exchange.REST_HTTP_URI the RestProducer should
remove Exchange.HTTP_PATH header
Key: CAMEL-11092
URL: https://issues.apache.org/jira/browse/CAMEL-11092
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Zoran Regvart
Assignee: Zoran Regvart
One of patterns in using microservices is consuming REST and producing from
REST resources using REST component. For instance have a frontend exposed API
using REST DSL and calling backend using REST producer.
As most HTTP components generate URIs by concatenating
{{Exchange.REST_HTTP_URI}} and {{Exchange.HTTP_PATH}} when the REST producer
generates {{Exchange.REST_HTTP_URI}} header that contains the whole URI to be
used it should remove the {{Exchange.HTTP_PATH}} header in order to prevent
incorrect URIs.
For example {{Exchange.HTTP_PATH}} is set by the REST consumer to
{{/api/pet/123}}, and REST producer is configured with
{{Exchange.REST_HTTP_URI}} with URI {{/api/pet/{petId}}} if the
{{Exchange.HTTP_PATH}} is not removed HTTP component (IMHO all except for
Restlet) would try to send the request to
{{/api/pet/{petId}/api/pet/123}}.
