[jboss-jira] [JBoss JIRA] (WFWIP-151) HTTP Verb OPTIONS requires to have Accept header defined, response should provide some guidance about this

[Jeff Mesnil (Jira)]

     [ https://issues.jboss.org/browse/WFWIP-151?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jeff Mesnil resolved WFWIP-151.
-------------------------------
    Resolution: Deferred


This type of enhancement should be done at the MP Metrics level (or at least in SmallRye implementation) which is where the HTTP endpoints are specified.

Once they are specified, we can then support them in WildFly.

> HTTP Verb OPTIONS requires to have Accept header defined
> {code}
> $ curl -X OPTIONS http://127.0.0.1:10090/metrics/vendor
> No exporter found for method OPTIONS and media type

> I have to specify json mediatype

> curl -X OPTIONS -H "Accept: application/json" http://127.0.0.1:10090/metrics/vendor

> Error 406: CWMMC0000I: The accept header format */* is incorrect.
> {code}

> Update:
> Spec requires header to be defined, so WF could be a bit more helpful in the response message
> {code}
> The implementation must return a 406 response code if the request’s HTTP Accept header 
> for an OPTIONS request does not match application/json.
