Summary: ODataResponse and POST, PUT, DELETE
Key: OLINGO-1031
URL: https://issues.apache.org/jira/browse/OLINGO-1031
Project: Olingo
Issue Type: Question
Components: odata2-core
Affects Versions: V2 2.0.1
Reporter: M Carissimi
Hello,
we have an OData 2 service which currently only supports GET requests. We are
investigating what is required to extend the service to support POST, PUT and
DELETE.
Looking at your documentation, it appears that we can use the the writeEntry()
and writeFeed() methods of the EntityProvider class to perform the required
operations. These methods return an ODataResponse. Can we use the ODataResponse
to provide error messages to the clients in case the POST/PUT operations can't
be completed successfully?
Delete operations are quite different as clients simply need to use the DELETE
method against an entry URL to delete it. In these cases how can we handle
error conditions? What error code should we return when an entry can't be
deleted and how can we tell the client the reason for the failure?
Finally, we would like to enforce that client invoking POST, PUT, DELETE
operations provide an audit message... How can we achieve this? Do we need to
get the clients to POST the audit message first and the reference it in the
other operations?
Thank you for the information
