Devo inviare una richiesta POST a un server Web e poter leggere la risposta inviata da detto server. Ho provato ad utilizzare il lib HTTPBuilder con questo codice:Groovy HTTPBuilder: acquisizione del contenuto dell'entità da una risposta GZIPed Chunked
def http = new HTTPBuilder('http://myServer/')
http.setProxy("Proxy_IP", 8080, "http")
postBody = [cmd:'e',format:'sep',c:'a',b:'b',t:'u',r:'r',kl:'lop']
http.post(body: postBody,
requestContentType: URLENC){ resp ->
HttpEntity he = resp.getEntity()
println "${resp.getAllHeaders()}"
println he.getContentType()
println "${resp.getEntity().getContent()}"
}
ottengo un'eccezione quando viene eseguito questo codice:
ERROR errors.GrailsExceptionResolver - EOFException occurred when processing request: [GET] /PROJECT/home/index
Unexpected end of ZLIB input stream. Stacktrace follows:

ho acceso il debug per filo e le intestazioni e questo è quello che ottengo :

quindi credo che il problema deriva dal fatto che la risposta viene inviato con:
012.351.641.061.Transfer-Encoding: chunked
Content-Encoding: gzip
C'è un altro modo per farlo? Sto sbagliando? Ho provato su google per un po 'di tempo e non ho trovato un buon vantaggio. Mi sembra che la lib di HTTPBuilder stia ottenendo il contenuto dell'entità dopo la chiusura della chiusura ma una volta uscito da quella chiusura, non posso accedere al contenuto dell'entità (l'eccezione è: Impossibile accedere al flusso chiuso)
gradirei l'aiuto su questo;)
