[groovy-user] Problem with RESTClient oauth feature

[Anand Bhagwat]

Hi,
I am using below code to access twitter rest api.

        RESTClient restClient = new RESTClient('https://twitter.com/statuses/' )
        restClient.setProxy proxyHost, proxyPort, "http"
        restClient.auth.oauth config.twitter.consumerKey, config.twitter.consumerSecret, accessToken, accessTokenSecret

        def resp = restClient.get(path : 'public_timeline.json')
        resp.getData()

But I am getting following stacktrace.

Stacktrace follows:
java.lang.ClassCastException: org.apache.http.message.BasicHttpRequest cannot be cast to org.apache.http.client.methods.HttpUriRequest

Any idea as to what is wrong here? I am using following dependencies in my grails project.

        compile 'oauth.signpost:signpost-core:1.2.1.1'
        compile('org.openid4java:openid4java:0.9.5') {
            excludes "xml-apis"
        }
        compile('org.codehaus.groovy.modules.http-builder:http-builder:0.5.1')
        compile('org.scribe:scribe:1.0.6')
        runtime('oauth.signpost:signpost-commonshttp4:1.2.1.1')

Regards,
Anand.

It looks like it's because your request is being redirected and the intermediate BasicHttpRequest isn't what I'm expecting.  Interesting... Can you open an issue here:
http://jira.codehaus.org/browse/GMOD
and assign it to the HttpBuilder component?

I'll get it fixed in 0.5.2.

Thanks.
