Handling RESTClient post() responses with no content-type or body.

[Jon Britton]

Hi,
I'm using RESTClient from the HTTP Builder module to send a POST request to GeoServer.  However, the response to my request doesn't contain a content-type or body so I get the following followed by a number of exceptions:

05-Nov-2009 14:12:42 groovyx.net.http.ParserRegistry getContentType
WARNING: Could not parse content-type header in response

Followed by exceptions.  How can I get around this?  All I want from the response is the status code, I'm not interested in anything else.  My code is shown below.

Thanks,

Jon

Code:

def createWorkspace(def wsName, def geoserverUrl, def user, def pass){
        // setup the restclient
        def geoserver = new RESTClient(geoserverUrl)
        // do the authing
        geoserver.auth.basic user, pass
        // post it
        def res = geoserver.post( path: "geoserver/rest/workspaces",
                        requestContentType: XML,
                body: "<workspace><name>${wsName}</name></workspace>"
        )
}

def code = createWorkspace("hello", "http://localhost:8080/", "admin", "geoserver")

Hmm interesting.  I was under the assumption that a POST response
should include _some_ sort of response body, but maybe that's not
technically required by the HTTP spec.  If you can send me the
exception stack trace I'm sure I can fix it, but I can't tell you what
you yourself can do until you give me some more details.

Better yet, if you can file a JIRA here: http://jira.codehaus.org/browse/GMOD
that would be super awesome (put the bug under the "HTTPBuilder"
module).  And If you really want to earn karma points, give enough of
an example that I can reproduce the error condition myself :)  I don't
konw if GeoServer has an open API, but if they do I can add it to the
unit tests.

Thanks.

Hi Tom, thanks for the quick response.

The equivalent response using cUrl looks like:

curl -d'<workspace><name>dwins</name></workspace>' -H'Content-type: text/xml' http://admin:geoserver@localhost:8080/geoserver/rest/workspaces -D -
HTTP/1.1 201 Created
Date: Wed, 04 Nov 2009 16:19:11 GMT
Location: http://localhost:8080/geoserver/rest/workspaces/dwins
Server: Noelios-Restlet-Engine/1.0..8
Transfer-Encoding: chunked

The API reference for the GeoServer REST interface can be found here: http://docs.geoserver.org/trunk/en/user/extensions/rest/rest-config-api.html

I'm new to REST as well as Groovy so I thought it might be a problem with my code.

Anyway, I'll check out JIRA now :-)

Thanks for the help,

Jon

Nope, you're right; in that case, the response object should be
available, and the 'data' property (which is the parsed response body)
should just be null.  Definitely a bug.

However, after looking at the stack trace, I don't think you should be
getting an NPE but an IllegalArgumentException (this is still
erroneous in the case of RESTClient, but it's due to RESTClient's
underlying use of HTTPBuilder).  What version of HTTPBuilder are you
using?

In either case, the bug still stands; I'll start working on it
soon-ish.  You can work around it for now by using the HTTPBuilder
class directly, which other than being slightly more verbose can do
the exact thing you're doing with RESTClient.

import static groovyx.net.http.Method.POST
import static groovyx.net.http.ContentType.XML

def http = new HTTPBuilder(
'http://admin:geoserver@localhost:8080/geoserver/rest/workspaces' )
http.handler.SUCCESS = { return it }

def response = http.request( POST, XML ) {
  body = '<workspace><name>dwins</name></workspace>'
}

assert response.status == 201


Let me know if you have any trouble with the above example.

Hey Tom,
 
This sounds familiar to the problem I reported to you earlier in the year.  I used RESTEasy's simple example and the status code was 201 and no body returned at all.   The real case I am using does a POST and does return a body so it wasn't a real problem for me.

[Tom Nichols]

Hi Mike,

Yes, I recall your question; I fixed the NPE that Jon is seeing
(that's why I think he's using an older version of HTTPBuilder.)
However I think even after he upgrades he might still encounter an
exception.  I don't think I fully understood the context of your
problem where the 201 doesn't return any response body, but RESTClient
expects one.  At least, taking a quick look at the current source
code, I _think_ there will still be a problem once Jon upgrades to
0.5.0-RC2.  But Jon, it would be helpful to see the behavior from the
lastest version.

Thanks for pointing that out Mike.
-Tom

Hi,

I was using 0.5.0-RC2 when I send my post now I'm using 0.5.0-SNAPSHOT with the same result.

Hi Mike,

Yes, I recall your question; I fixed the NPE that Jon is seeing
(that's why I think he's using an older version of HTTPBuilder.)
However I think even after he upgrades he might still encounter an
exception.  I don't think I fully understood the context of your
problem where the 201 doesn't return any response body, but RESTClient
expects one.  At least, taking a quick look at the current source
code, I _think_ there will still be a problem once Jon upgrades to
0.5.0-RC2.  But Jon, it would be helpful to see the behavior from the
lastest version.

Thanks for pointing that out Mike.

Actually 0.5.0-RC2 should be sufficient.  But I'm still confused how
you could be seeing that NPE seeing as how in RC2 it's caught and
wrapped:
http://fisheye.codehaus.org/browse/gmod/httpbuilder/tags/0.5.0-RC2/src/main/java/groovyx/net/http/ParserRegistry.java?r=HEAD#l153
Again, not to say there isn't a bug in my parsing logic (there is!)
but I'm just confused about the exception you're seeing.

Did you happen to open up a JIRA?  I just wanted to check before I
open up a duplicate on accident.

Thanks.
-Tom

Hi again, I'm just trying your example without using RESTClient but it doesn't work. My code is below, followed by the error I receive.  What's could be causing this?

Thanks,

Jon

CODE:

def createWorkspace(def wsName, def geoserverUrl, def user, def pass){
        def http = new HTTPBuilder( "${geoserverUrl}/geoserver/rest/workspaces" )
        http.handler.SUCCESS = { return it }
       
        def response = http.request( POST, XML ) {
                body = "<workspace><name>${wsName}</name></workspace>"
        }
       
        assert response.status == 201
}

//Call method
def code = createWorkspace("hello1", "http://admin:geoserver@localhost:8080/", "admin", "geoserver")

OUTPUT:

Caught: groovy.lang.MissingMethodException: No signature of method: groovyx.net.http.HTTPBuilder.request() is applicable
 for argument types: (groovyx.net.http.Method, groovyx.net.http.ContentType, uk.ac.glam.rest.GroovyTest$_createWorkspace
_closure2) values: [POST, application/xml, uk.ac.glam.rest.GroovyTest$_createWorkspace_closure2@2fb002]
        at uk.ac.glam.rest.GroovyTest.createWorkspace(GroovyTest.groovy:54)
        at uk.ac.glam.rest.GroovyTest.run(GroovyTest.groovy:70)

Nope, you're right; in that case, the response object should be
available, and the 'data' property (which is the parsed response body)
should just be null.  Definitely a bug.

However, after looking at the stack trace, I don't think you should be
getting an NPE but an IllegalArgumentException (this is still
erroneous in the case of RESTClient, but it's due to RESTClient's
underlying use of HTTPBuilder).  What version of HTTPBuilder are you
using?

In either case, the bug still stands; I'll start working on it
soon-ish.  You can work around it for now by using the HTTPBuilder
class directly, which other than being slightly more verbose can do
the exact thing you're doing with RESTClient.

import static groovyx.net.http.Method.POST
import static groovyx.net.http.ContentType.XML

def http = new HTTPBuilder(
'http://admin:geoserver@localhost:8080/geoserver/rest/workspaces' )
http.handler.SUCCESS = { return it }

def response = http.request( POST, XML ) {
  body = '<workspace><name>dwins</name></workspace>'
}

assert response.status == 201


Let me know if you have any trouble with the above example.
-Tom

hmm, I'm not sure what to tell you; I just copied your example into a
Groovy console and ran it, and I didn't get the MissingMethodException
that you're seeing there, using 0.5.0-RC2.

Try this variation:
def http = new groovyx.net.http.HTTPBuilder(
"http://localhost:8080/geoserver/rest/workspaces" )
http.handler.SUCCESS = { return it }

def response = http.post( headers:['Content-Type': 'text/xml'],
    body: "<workspace><name>bob</name></workspace>" )

assert response.status == 201

Hi Jon,

I just deployed a new 0.5.0-SNAPSHOT release; this should fix the
empty response body issue.  For RESTClient responses, response.data
should simply be null.  But all header/ response code information
should be readily available.  Please give it a try and let me know
what you find.

Thanks.
-Tom

Not to be picky, nor I am saying the link I am providing is authoritative, but 201 SHOULD return a response which is the locations of the entity created. I realize that is being 'opinionated' and 'technical', as opposed to "Well here's the real world..."  But that has always been my understanding. CREATED means there is a new resource and a URI for it. Those representations, even if only one, should be in the entity returned with the most specific in the Location header

MMmm, you're right; in most cases, the entity is returned, not just
the Location header.  Unfortunately, REST is a somewhat loosely
defined spec and I'm sure there are going to be plenty of examples of
divergances from what "should" be done.  The RESTClient should be able
to handle a POST without a response entity, so I've updated the latest
SNAPSHOT to handle it.

Hi Tom,

I've just tried again with 0.5.0-SNAPSHOT and my original code (the RESTClient one) and I'm still getting the same exceptions (NullPointerException, IllegalArgumentException and ResponseParseException).

Again, here is the code I'm using:

def createWorkspace(workspace, geoserverUrl, user, pass){
        // setup the restclient
        def geoserver = new RESTClient(geoserverUrl)
        // do the authing
        geoserver.auth.basic user, pass
        // post it
        def res = geoserver.post( path: "/geoserver/rest/workspaces",
                        requestContentType: XML,
                body: "<workspace><name>${workspace}</name></workspace>"
        ).getStatus()
}

I guess this is all GeoServers fault?

Jon

Hi Jon,

I just deployed a new 0.5.0-SNAPSHOT release; this should fix the
empty response body issue.  For RESTClient responses, response.data
should simply be null.  But all header/ response code information
should be readily available.  Please give it a try and let me know
what you find.

Thanks.
-Tom

Hi Jon,

Are you sure you got an updated snapshot?  It was published on Nov
6th.  You can get the timestamped version of the JAR here:
http://snapshots.repository.codehaus.org/org/codehaus/groovy/modules/http-builder/http-builder/0.5.0-SNAPSHOT/http-builder-0.5.0-20091107.042829-12.jar

I'm surprised that you'd see _no_ change in the behavior.  Although
part of the problem is I'm trying to fix this "blind," so to speak,
without being able to reproduce it myself.  Can you point me to a
public GeoServer instance, or your dev server which I can use to test
things while I develop the fix?  I'm certain this is not just
GeoServer's fault.  While uncommon, it's not a requirement for a
response to contain a body.  Therefore RESTClient should be able to
handle the case and I'm more than willing to work with you to get it
fixed in the HTTPBuilder code.

Can you please also verify that the exception stack trace is
identical, once you've verified that you're using an updated snapshot?
 Thanks.

-Tom

Hi,

I used Maven to update my dependencies and I'm pretty certain that I'm using the right JAR.  I don't have access to a public GeoServer instance unfortunately, although it's pretty easy to install GeoServer on a local machine (you also need the GeoServer REST plugin which you need to put in webapps/geoserver/web-inf/lib/) especially if you happen to have Tomcat running (you can get a WAR).

One strange thing is that Eclipse seems to show http-builder-0.5.0-SNAPSHOT.jar, even though Maven downloaded the timestamped version.  I'm not sure if it actually replaced it, but it doesn't matter because I get the same result regardless of the JAR I use.

Here is the stack trace again so you can see the line numbers etc:

Hi Jon,

Are you sure you got an updated snapshot?  It was published on Nov
6th.  You can get the timestamped version of the JAR here:
http://snapshots.repository.codehaus.org/org/codehaus/groovy/modules/http-builder/http-builder/0.5.0-SNAPSHOT/http-builder-0.5.0-20091107.042829-12.jar

I'm surprised that you'd see _no_ change in the behavior.  Although
part of the problem is I'm trying to fix this "blind," so to speak,
without being able to reproduce it myself.  Can you point me to a
public GeoServer instance, or your dev server which I can use to test
things while I develop the fix?  I'm certain this is not just
GeoServer's fault.  While uncommon, it's not a requirement for a
response to contain a body.  Therefore RESTClient should be able to
handle the case and I'm more than willing to work with you to get it
fixed in the HTTPBuilder code.

Can you please also verify that the exception stack trace is
identical, once you've verified that you're using an updated snapshot?
 Thanks.

-Tom

[Tom Nichols]

Hi Jon,

I fired up a GeoServer instance to track down how the HttpClient API
behaves when there's no response body; it's slightly different than
advertised in the JavaDocs, which is what caused me grief.  Anyway, I
fixed HTTPBuilder/ RESTClient's behavior for your situation, so the
latest 0.5.0-SNAPSHOT (just deployed) should handle this gracefully
now.  When you update, use the -U maven flag to force it to check for
a new snapshot.  Maven renames the latest timestamped snapshot JAR to
artifactName-version-SNAPSHOT.jar when it's downloaded to the local
repository I think; that's why you might see Maven download a
timestamped JAR but then it shows up in the classpath as
-SNAPSHOT.jar.

Anyway, let me know if you have any troubles with it now.

-Tom
