decompress Apache httpclient results - apache-httpclient-4.x

Question

I'm using Apache HTTPClient 4.5.3 to make some HTTP requests, but I am getting a g-zipped response I have tried many things I found online but non of them worked. I still get gibberish when I print the response. Below are the relevant code. What do I need to do to get a human readable response?
static public CloseableHttpClient CreateHttpClient() {
// return
// HttpClients.custom().disableAutomaticRetries().setHttpProcessor(HttpProcessorBuilder.create().build())
// .build();
return HttpClientBuilder.create().disableAutomaticRetries()
.setHttpProcessor(HttpProcessorBuilder.create().build()).build();
}
static public RequestConfig GetConfig() {
return RequestConfig.custom().setSocketTimeout(READTIMEOUT).setConnectTimeout(CONNECTTIMEOUT)
.setConnectionRequestTimeout(REQUESTTIMEOUT).build();
}
static public String updates() {
String result = "";
String url = "https://example.com";
CloseableHttpClient httpClient = CreateHttpClient();
CloseableHttpResponse response = null;
URL urlObj;
RequestConfig config = GetConfig();
try {
urlObj = new URL(url);
HttpPost request = new HttpPost(url);
request.setConfig(config);
StringEntity params = new StringEntity("example");
request.addHeader("Accept-Language", "en");
request.addHeader("Content-Type", "application/json; charset=UTF-8");
request.addHeader("Content-Length", String.valueOf(params.getContentLength()));
request.addHeader("Host", urlObj.getHost());
request.addHeader("Connection", "Keep-Alive");
request.addHeader("Accept-Encoding", "gzip");
request.setEntity(params);
response = httpClient.execute(request);
int responseCode = response.getStatusLine().getStatusCode();
System.out.println("updates response code: " + responseCode);
// BufferedReader rd = new BufferedReader(new
// InputStreamReader(response.getEntity().getContent(), "UTF-8"));
result = EntityUtils.toString(response.getEntity());
// String line = "";
// while ((line = rd.readLine()) != null) {
// result.append(line);
// }
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (response != null)
response.close();
httpClient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return result;
}

You should get the content from the response entity which is an InputStream. Than you could create a String from that InputStream with BufferedReader
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String result = convertInputStreamToString(instream);
instream.close();
}
Write your own convertInputStreamToString. If you need help for doing that check here:
