Extracting gzip data from Apache-httpclient without decompression

问题

I'm using apache httpclient 4.3.5 to send a request to an upstream server which returns a gzipped response. I need to pass this response AS-IS to a downstream server without any form of decompression. However, httpclient is far too helpful and insists on decompressing the response and I can't find any way of persuading it to stop.

CloseableHttpClient client = HttpClients.createDefault();
CloseableHttpResponse serverResponse = client.execute(serverRequest);
try {
    HttpEntity entity = serverResponse.getEntity();
    downstreamResponse.setStatus(serverResponse.getStatusLine().getStatusCode());
    for (Header header : serverResponse.getAllHeaders()) {
        downstreamResponse.setHeader(header.getName(), header.getValue());
    }
    entity.writeTo(downstreamResponse.getOutputStream());
    downstreamResponse.flushBuffer();
} finally {
    serverResponse.close();
}

I'm sure that there is some way of configuring the client using some form of the construct

return HttpClients.custom()
    ....
    .build();

but I can't find it. Can the experts please advise?

回答1:

CloseableHttpClient client = HttpClients.custom()
        .disableContentCompression()
        .build();
