ksoap2 (Android) and GZIPped BasicHttpBinding

Question

I want to consume a BasicHttp WCF web service with ksoap2 that is compressed by GZIP.

Is there a way to do this in the Android version of ksoap2 (http://code.google.com/p/ksoap2-android/) or is there another way?

Answer 1

I have create a class that extend the HTTPTransportSe and overrode the call() method and added this line to the code (taken from here https://github.com/mosabua/ksoap2-android/blob/master/ksoap2-j2se/src/main/java/org/ksoap2/transport/HttpTransportSE.java)

connection.setRequestProperty("Accept-Encoding","[Here you have to put the encoding]");

Then when I get the InputStream I use the retHeaders variable to check if there's the encoding.

if (retHeaders != null){
            Iterator it = retHeaders.iterator();
            boolean found = false;
            String encoding = "";
            while (it.hasNext()){
                HeaderProperty temp = (HeaderProperty) it.next();
                if (temp.getKey().contentEquals("content-encoding")){
                    found = true;
                    encoding = temp.getValue();
                }
            }
            if (found){
                is = new GZIPInputStream(is, new Inflater(true));
                ByteArrayOutputStream bos = new ByteArrayOutputStream();
                byte[] buf = new byte[256];
                while (true) {
                    int rd = is.read(buf, 0, 256);
                    if (rd == -1)
                        break;
                    bos.write(buf, 0, rd);
                }
                bos.flush();
                buf = bos.toByteArray();
               is.close();
                is = new ByteArrayInputStream(buf);
            }
        }
        parseResponse(envelope, is);

And then you have to pass the "is" to the parser. If there's a better way to code it I will happy to know about it. .))
