Enforcing HTTP accept header

[legege]

Hi,

Is there a way to enforce the HTTP Accept header?

Thanks

[Ben R Vesco]

As in, enforce a particular value in it?

Check here:
http://wiki.restlet.org/docs_2.0/13-restlet/27-restlet/130-restlet.html

which shows us we can get the value from the header by querying the
ClientInfo object like this:
request.getClientInfo().getAcceptedMediaTypes()

Which will return a list of the media types that were sent in that
header. What you do with that info is pretty application specific.
Perhaps a Filter that verifies the value in the "beforeHandle" method
and takes some action if the values are not favorable? That would be a
way to enforce it on every request. You could also verify it per
resource or some other solution.

Hi all,

In addition to Ben's excellent reply, I would point that ServerResource
subclasses can enforce the media types they accept using annotation
parameters, such as:

@Put(xml)
public void store(Document doc){
   ...
}

More details in the Javadocs or here:

I guess the correct syntax would be:

@Put("xml")
public void store(Document doc) {
...
}

Same goes for @Get annotation.

You can get a list of supported out-of-the-box extensions here

http://www.restlet.org/documentation/2.0/jse/api/org/restlet/service/MetadataService.html#addCommonExtensions()

And use the values there as (String) parameters to the annotations.
