I wrote a post that tries to explain all the crazy cases you need to
handle to dispatch Friend responses based on content type:

Liberator can be helpful for this.

Hi,
I'm trying to get a simple use case running - send a login request to
/login and get success or fail response, preferably in JSON format.
I followed the example in https://github.com/cemerick/friend#workflows
<https://github.com/cemerick/friend#workflows>
(def users {"root" {:username "root"
:password (creds/hash-bcrypt "admin_password")
:roles #{::admin}}
"jane" {:username "jane"
:password (creds/hash-bcrypt "test")
:roles #{::user}}})
(defroutes app-routes
(GET "/test" [] {:body {:my-map "helo"}})
(route/resources "/")
(route/not-found "Not found"))
(def app
(->
(handler/api app-routes)
(middleware/wrap-json-body)
(middleware/wrap-json-response)
(friend/authenticate {:credential-fn (partial
creds/bcrypt-credential-fn users)
:workflows [
(workflows/interactive-form)]})
)
)
I'm testing with curl:
curl -v --data "username=jane&password=test" http://localhost:3000/login
Or:
curl -v --request POST
"http://localhost:3000/login?username=jane&password=test
<http://localhost:3000/login?username=jane&password=test>"
And I get:
* About to connect() to localhost port 3000 (#0)
* Trying ::1...
* connected
* Connected to localhost (::1) port 3000 (#0)
> POST /login?username=jane&password=test HTTP/1.1
> User-Agent: curl/7.24.0 (x86_64-apple-darwin12.0) libcurl/7.24.0
OpenSSL/0.9.8y zlib/1.2.5
> Host: localhost:3000
> Accept: */*
>
< HTTP/1.1 302 Found
< Date: Wed, 23 Apr 2014 22:25:15 GMT
< Location: http://localhost:3000/login?&login_failed=Y&username=
<http://localhost:3000/login?&login_failed=Y&username=>
< Content-Length: 0
< Server: Jetty(7.6.8.v20121106)
<
* Connection #0 to host localhost left intact
* Closing connection #0
This looks like authentication failed, but the data is correct. I
reviewed the curl request, and this seems to be the correct way to
send a POST. But &username= gives me the impression it's not being
parsed correctly.
Also, how can I get a JSON response instead of only a header?
Thanks.
P.S. Maybe it would be positive if this library has an own Google Group.
