Android:HTTP 通信应使用“Accept-Encoding: gzip"； [英] Android: HTTP communication should use "Accept-Encoding: gzip"

问题描述

我有一个与请求 JSON 数据的网络服务器的 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 References 中搜索 gzip 没有显示任何与 HTTP 相关的内容，如您所见 此处.

I've a HTTP communication to a webserver requesting JSON data. I'd like compress this data stream with Content-Encoding: gzip. Is there a way I can set Accept-Encoding: gzip in my HttpClient? The search for gzip in the Android References doesn't show up anything related to HTTP, as you can see here.

推荐答案

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:

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

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

检查内容编码的响应:

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