I guess by “HTTP protocol” you actually meant “HTTP method”. The reason
I want to add a ‘method’ attribute is that I want the controller to be
able to provide a RESTful API, where each HTTP method has semantics
attached to it [1].
The controller is where requests are dispatched to there corresponding
handler (event, service, view). Currently it is written in a RPC way
where URI refers to *actions* instead of *resources*. For example take
the Geo management from the webtools controller:
<request-map uri="LookupGeo">...</request-map>
<request-map uri="createGeo">...</request-map>
<request-map uri="updateGeo">...</request-map>
<request-map uri="deleteGeo">...</request-map>
In order to implement a RESTful API with the same capability. The idea
is to define a “geos” resouce which is a container of geo resources and
implement the different *actions* available on those resources via the
various HTTP methods available. So this would convert into something
like this:
<request-map uri="geos" method="get">...</request-map>
<request-map uri="geos" method="post">...</request-map>
<request-map uri="geos/{id}" method="update">...</request-map>
<request-map uri="geos/{id}" method="delete">...</request-map>
The last two examples requires additional changes that are not
implemented in the patches from OFBIZ-10458:
- Handling URI templates
- Replacing the overridden view URI feature with an alternate solution.
I am currently working on this in parallel of the JSON view handler.
Does this additional explanation and example help?
Thanks for the feedback.
