I haven't used GZip, but I would assume that you should use the input stream from your <code>HttpURLConnection</code> or <code>HttpResponse</code> as <code>GZIPInputStream</code>, and not some specific other class.

blocks|key|1429883|text|您应该使用http标头来指示连接可以接受gzip编码的数据，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1429884|HttpUriRequest+request+=+new+HttpGet(url);
request.addHeader("Accept-Encoding",+"gzip");
//+...
httpClient.execute(request);|code-block|syntax|javascript|1429885|检查内容编码的响应：|1429886|InputStream+instream+=+response.getEntity().getContent();
Header+contentEncoding+=+response.getFirstHeader("Content-Encoding");
if+(contentEncoding+!=+null+&&+contentEncoding.getValue().equalsIgnoreCase("gzip"))+{
++++instream+=+new+GZIPInputStream(instream);

You should use http headers to indicate a connection can accept gzip encoded data, e.g:

<pre><code>HttpUriRequest request = new HttpGet(url);
request.addHeader("Accept-Encoding", "gzip");
// ...
httpClient.execute(request);
</code></pre>

Check response for content encoding:

<pre><code>InputStream instream = response.getEntity().getContent();
Header contentEncoding = response.getFirstHeader("Content-Encoding");
if (contentEncoding != null &amp;&amp; contentEncoding.getValue().equalsIgnoreCase("gzip")) {
 instream = new GZIPInputStream(instream);
}
</code></pre>

blocks|key|1215097|text|如果你使用的是8级或更高级别的API8，那就是AndroidHttpClient。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1215098|它有一些辅助方法，比如：|1215099|public+static+InputStream+getUngzippedContent+(HttpEntity+entity)|code-block|syntax|javascript|1215100|和|1215101|public+static+void+modifyRequestToAcceptGzipResponse+(HttpRequest+request)|1215102|导致更简洁的代码：|1215103|AndroidHttpClient.modifyRequestToAcceptGzipResponse(+request+);

If you're using API level 8 or above there's <a href="http://developer.android.com/reference/android/net/http/AndroidHttpClient.html">AndroidHttpClient</a>.

It has helper methods like:

<pre><code>public static InputStream getUngzippedContent (HttpEntity entity)
</code></pre>

and 

<pre><code>public static void modifyRequestToAcceptGzipResponse (HttpRequest request)
</code></pre>

leading to much more succinct code:

<pre><code>AndroidHttpClient.modifyRequestToAcceptGzipResponse( request );
HttpResponse response = client.execute( request );
InputStream inputStream = AndroidHttpClient.getUngzippedContent( response.getEntity() );
</code></pre>

blocks|key|1215159|text|在我的例子中是这样的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1215160|URLConnection+conn+=+...;
InputStream+instream+=+conn.getInputStream();

In my case it was like this:

<pre><code>URLConnection conn = ...;
InputStream instream = conn.getInputStream();
String encodingHeader = conn.getHeaderField("Content-Encoding");
if (encodingHeader != null &amp;&amp; encodingHeader.toLowerCase().contains("gzip"))
{
 instream = new GZIPInputStream(instream);
}
</code></pre>

I've a HTTP communication to a webserver requesting JSON data. I'd like compress this data stream with <code>Content-Encoding: gzip</code>. Is there a way I can set <code>Accept-Encoding: gzip</code> in my HttpClient? The search for <code>gzip</code> in the Android References doesn't show up anything related to HTTP, as you can see <a href="http://developer.android.com/search.html#q=gzip&amp;t=0" rel="noreferrer">here</a>.

我与请求JSON数据的‘ve服务器进行了HTTP通信。我想用Content-Encoding: gzip压缩这个数据流。有没有办法在我的HttpClient中设置Accept-Encoding: gzip？在Android参考资料中搜索gzip并没有显示任何与HTTP相关的内容，正如您所看到的。
