Re: Problems with URL params and http-agent
Hmm, this is a good idea and I got the GET request string as...
*/exist/rest/rootDir/system.main.system/aauthentication.main.authentication/users.aauth.users/user.one/user.one?_wrap=no_query=declare
default element namespace 'com/interrupt/bookkeeping/users';//user[
@id='one']*
This exact URI (behind http://localhost:8080) works when used by the
browser, or wget. The service is a RESTful interface around the eXist XML
DB. And I'm suspecting the DB is returning the correct result, I'm just not
handling it somehow in clojure. I though my code was pretty straight forward
(carbon copy of Stuart Halloway's handler).
(clojure.contrib.http.agent/result (clojure.contrib.http.agent/http-agent
http://localhost:6300/exist/rest/rootDir/system.main.system/aauthentication.main.authentication/users.aauth.users/user.one/user.one?_wrap=no_query=declaredefault
element namespace 'com/interrupt/bookkeeping/users';//user[
@id='one']
:method GET
:header {Content-Type text/xml}
:handler (fn [agnt]
(with-open [w (clojure.contrib.io/writer /tmp/out)]
(clojure.contrib.io/copy (clojure.contrib.http.agent/stream agnt) w))
)
)
)
Hmmm

It's hard to say without the specific error you're seeing and what
service you're hitting, but one technique I've used for debugging HTTP
calls is to setup netcat on another port. Then make the same requests
with the browser and library to the new port and compare netcat's
output. Perhaps they are escaping the paths differently. Cheers,

Oh... and the /tmp/out file is empty.

Re: Problems with URL params and http-agent
That's a good idea which I tried. But no dice. I have a feeling I'm not handling the response properly in Clojure. See my other posts here.
