HTTP responses without content-type sometimes returned as Clojure HashMap

[Francis Hitchens]

Hi,

I am receiving responses from a downstream server that have identical HTTP headers (neither have a content-type header). One message gets converted back to a proper HTTP response at the client by the compojure route, the other always returns to the client as a Clojure HashMap. I have tried (conj {:content-type :text/xml} response) but still I get a HashMap coming back.

Any ideas?

regards, Francis.

What exactly do you mean by this? Could you provide a code sample?

Sure, sorry I was a bit vague.

What is happening is that the Clojure HashMap response I am getting back from clj-http.client/post is not getting converted at all to a proper HTTP response when seen by the curl client. 

This is the curl response...

{:content-type-params {} :content-type :text/html :body etc}

It's a valid clojure.lang.PersistentArrayMap and identical to what came back from the client/post call.

I must somehow have screwed up something in the defroutes macro that is bypassing the clojure to HTTP response conversion. I can't see it though. Looks identical to all other routes I have set up.

You'll need to provide some code, I'm afraid. I can't think of anything obvious that would cause this.

Ha, got it.

I had a 

(for [[env host] (get-host)]

Ha, got it.

I had a 

(for [[env host] (get-hosts) :while (= env e) ]

  (do

     (log env)

     (post-to host)))

type of thing that I guess was returning the Clojure HashArray response plus a nil, causing me hours of confusion.
