Groovy HTTPBuilder Herstellung von Fehler beim Parsen gültiges json

Ich bin ein Groovy-Anfänger und versuche zu verbinden, um die GitHub-API von einem groovy-Skript aber ich erhalte eine seltsame Fehlermeldung, wenn HTTPBuilder versucht zum Parsen der JSON-Antwort.

Mein einfaches Skript ist wie folgt

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.2' )
import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*

def apiToken = '[api_token]'

def http = new HTTPBuilder( 'https://api.github.com/' )

//perform a GET request, expecting JSON response data
http.request( GET, JSON ) {

  uri.path = '/orgs/octokit/repos'
  headers.'Accept' = 'application/json'
  headers.'Authorization' = 'Basic ' + (apiToken + ':').bytes.encodeBase64().toString()
  headers.'User-Agent' = '[username]'

  //response handler for a success response code:
  response.success = { resp, json ->
    println resp.statusLine
  }

  //handler for any failure status code:
  response.failure = { resp ->
    println "Unexpected error: ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}"
  }
}

Aber wenn die JSON geparst bekomme ich die folgende Fehlermeldung

Sep 06, 2014 10:21:54 PM groovyx.net.http.HTTPBuilder$1 handleResponse

Den Fehler zu suggerieren scheint, ungültige JSON-ich habe jedoch bestätigt die Antwort ist in der Tat gültig, als Sie erwarten würden von der Github API.

Was ist noch seltsamer ist, wenn ich entfernen Sie die 'Authorization' - header vollständig aus und senden die Anfrage nicht authentifiziert, funktioniert es einwandfrei :S

speichern Sie die json-Antwort und versuchen Sie zu analysieren, es groovy ist json-parser
Könnten Sie bitte geben Sie die JSON-Antwort, die Sie bekommen?
Der code funktioniert gut für mich.

Es ist ein Problem mit der neuesten Version von Groovy. Ich hatte das gleiche Problem. Dein code sollte funktionieren, mit der version von Groovy vor 2.3.0. Optional können Sie versuchen, eine andere Standard-JSONParserType für HTTPBuilder.

- Spot auf, wechselte zu 2.2.2 und seine Arbeit.

Hier ist mein code zu arbeiten, um

    /*
     * Normally we would use the method "request(GET, JSON)" to return a json result, but with the release
     * of groovy 2.3.0, which included extensive changes to JSON parsing, the result returned from the
     * Artifactory REST API call 'File List' could not be parsed by HTTPBuilder's default JSON parser.
     * 
     * Specifying the content type as TEXT removes the parsing from the call. Code was added to parse the returned
     * text into JSON using the more lenient 'LAX' parser.
     */
    http.request( GET, TEXT ) {
        //Since content type is text, we need to specify that a json response is acceptable. 
        headers.Accept = 'application/json'
        headers.'User-Agent' = USER_AGENT

        response.success = { respnse, reader ->

            def jsonText = reader.text
            def parser = new JsonSlurper().setType(JsonParserType.LAX)
            def jsonResp = parser.parseText(jsonText)
            //Add up the size of all the files in this directory
            //
            jsonResp.files.each {
                directorySize = directorySize + Integer.parseInt("${it.size}".toString())
            }
        }
    }

Aktualisieren Sie Ihre bestehenden Antwort, anstatt erstellen Sie eine 2.
Ich stehe vor das gleiche problem, aber leider ändern die Groovy-version ist keine option im moment. Irgendwelche Gedanken auf, wie Sie Ihre workaround angepasst werden könnte für ein Szenario, wo ich bin Entsendung JSON an den remote-service, oder bin ich dazu verdammt, so lange als Content-Type = applicaton/json?
Ich fand diese Problemumgehung - gist.github.com/zedar/abbb3c01635c0d6a977f Response handler Verschlüsse, die nur die Leser sind aufgerufen, vor JsonSlurper.

def bufferedText = response.entity.content.getText( ParserRegistry.getCharset( response ) ).trim()
def result =  new JsonSlurper().parseText( bufferedText )

Bitte keine post-code-nur Antworten. Erklären, wie der code funktioniert.
