Tomas Von Veschler commented on DTACLOUD-53:
--------------------------------------------
A curious finding, if I use the same User-Agent as Chrome, the content of the
response changes:
$ curl --url http://192.168.0.194/api/hardware_profiles --show-error --header
"Accept: application/json" -s -v --header "User-Agent:Mozilla/5.0 (X11; Linux
x86_64) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.74" 2>&1 | egrep
'(Accept|Content-Type)'
> Accept: application/json
< Content-Type: text/html;charset=utf-8
This is also preventing XMLHttpRequest calls from Chrome to work, while it's
working on Firefox.
> Wrong content type selected if multiple media types are supplied

> Key: DTACLOUD-53
> URL: https://issues.apache.org/jira/browse/DTACLOUD-53
> Project: DeltaCloud
> Issue Type: Bug
> Components: Server
> Reporter: Tomas Von Veschler
> Assignee: David Lutterkort
> Priority: Minor
>
> When setting the Accept header as for example: application/json, */* , seems
> that */* is picked up and XML content is returned instead of JSON. This
> doesn't follow the HTTP RFC (http://tools.ietf.org/html/rfc2616#section-14.1):
> Media ranges can be overridden by more specific media ranges or
> specific media types. If more than one media range applies to a given
> type, the most specific reference has precedence. For example,
> Accept: text/*, text/html, text/html;level=1, */*
> have the following precedence:
> 1) text/html;level=1
> 2) text/html
> 3) text/*
> 4) */*
> How to test it:
> $ curl --url http://192.168.0.194/api/hardware_profiles --show-error --header
> "Accept: application/json, */*" -s -v 2>&1 | egrep '(Accept|Content-Type)'
> > Accept: application/json, */*
> < Content-Type: application/xml;charset=utf-8
> $ curl --url http://192.168.0.194/api/hardware_profiles --show-error --header
> "Accept: application/json" -s -v 2>&1 | egrep '(Accept|Content-Type)'
> > Accept: application/json
> < Content-Type: application/json;charset=utf-8
> This causes problems to all jQuery users, as it sends
> "Accept:application/json, text/javascript, */*"
