Subject [jira] [Commented] (SOLR-1123) Change the JSONResponseWriter content type
Date Sun, 02 Oct 2011 22:20:34 GMT


Chris Tucker commented on SOLR-1123:

JSON is certainly popular, and I agree that many users have a visceral reaction against XML.
 However, we're talking here about maintaining current behavior to support one very specific
set of users: those who (1) are not committed enough to JSON to know how to view it (a plugin,
Firebug, or what have you, which they will need for *every other case* where they get JSON
from any other service out there) but (2) are committed enough to it to not be able/willing
to use the (arguably much better) XML visualization tools built into every browser.  This
just seems like a very small population of users.  Meanwhile, the current behavior thwarts
many serious users who *do* want to use a JSON plugin, makes it impossible to write content-type
aware servlet filters (which was my use case way back when), and violates the expectation
that a response will have the RFC defined content type associated with it.  IMHO the cost
vastly outweighs the benefit here: if need be, put a note on the wiki in the tutorial where
JSON is mentioned (which, as far as I can tell, is simply to say "hey, you can get the results
in JSON, too!") pointing people to a browser plugin and be done with it.

The reason for this as I understand is to enable viewing the json response as as text in the
browser. While this is valid argument, I do believe that there should at least be an option
to configure this writer to use the JSON content type. According to [RFC4627|]
the json content type needs to be application/json (and not text/x-json). The reason this
can be very helpful is that today you have plugins for browsers (e.g. [JSONView|])
that can render any page with application/json content type in a user friendly manner (just
like xml is supported).
