NFD team, any suggestions on scope violation connecting to WebSocket locally?

nfd.conf is same as nfd.conf.sample.
I have confirmed the scope violation issue by disabling scope checking in NFD.
(Commented out lines 116, 227, 320, 406 in daemon/fw/forwarder.cpp.)
Then the browser gets the data.

I have tried that example and the browser does not get anything.
NFD logs show that the interest for /localhost/nfd/faces/list is dropped due to scope violation.
Is your nfd.conf modified from /usr/local/etc/ndn/nfd.conf.sample , especially in the websocket section?
In https://github.com/named-data/ndn-js/blob/master/examples/browser/test-list-faces.html#L47
it says that a Unix socket is used to connect to the local forwarder, but nfd-status shows websocket.
Whoopsie! (That’s a typo from copying from the Node.js example.) You’re right. it connects with WebSocket. I fixed the comment.
Thanks,

See the example test-list-faces:

Hi all,
I am currently playing with NDN-js library, and I was wondering if it is possible to query the localhost (e.g. ndn:/localhost/nfd/faces/list) .
I could do that with node using UnixSocket. Is it possible to do it from a browser (knowing that the browser uses WebSockets) ?
Thanks.
