Decompression of GZIP:ed response (Grails / Groovy)

Question

I'm consuming a REST api using the RestBuilder plugin. I get a response where the body is compressed:

Content-Encoding=[gzip]

Does groovy/Grails provide any easy access / native methods for decoding gzip compression? The only thing I found is the native Java zip api (ex. GZIPInputStream). Does someone have a better idea?

Answer 1

Spring and HttpComponents will handle the decoding automatically:

HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory(HttpClientBuilder.create().build());
RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);

ResponseEntity<String> response = restTemplate.exchange(
        "some/url/", HttpMethod.GET, new HttpEntity<Object>(requestHeaders),
        String.class);
