Does Apache Commons HttpClient support GZIP?
提问by benstpierre
Does the library Apache Commons HttpClient support Gzip? We wanted to use enable gzip compression on our Apache server to speed up the client/server communications (we have a php page that allows our Android application to sync files with the Server).

Apache HttpClient 4.1 supports content compression out of the box along with many other features that were previously considered out of scope.
Apache HttpClient 4.1 支持开箱即用的内容压缩以及许多以前被认为超出范围的其他功能。

It has no support for this out-of-the-box, and it seems unlikely to be added to HttpClient 3.x (see rather bitchy JIRA issue here). You can, however, do it by adding custom request readers and manual request/response stream handling, layered on top of the basic library, but it's fiddly.
它不支持这种开箱即用的功能，并且似乎不太可能将其添加到 HttpClient 3.x（请参阅此处的JIRA 问题）。但是，您可以通过添加自定义请求读取器和手动请求/响应流处理来实现，这些处理位于基本库的顶部，但这很繁琐。
It seems you can do it with HttpClient 4, but not without some effort.
似乎您可以使用 HttpClient 4 来做到这一点，但并非不费吹灰之力。
Pretty shoddy, if you ask me, this stuff really should be easier than it is.
相当粗制滥造，如果你问我，这些东西真的应该比现在更容易。

If your server is able to provide GZIPped content, with Apache Http client 4.1 all you need is to use
如果您的服务器能够提供 GZIP 压缩的内容，那么您只需要使用 Apache Http 客户端 4.1
org.apache.http.impl.client.ContentEncodingHttpClient
which is a subclass of DefaultHttpClient.
它是 的子类DefaultHttpClient。
This client will also add headers saying that it accepts GZIPped content.
此客户端还将添加标头，说明它接受 GZIP 压缩的内容。

Custom Protocol Interceptorsmay help as well.
自定义协议拦截器也可能有所帮助。

It doesn't support it out of the box but you can transform entity of returned HttpResponseinto uncompressed one by calling
它不支持开箱即用，但您可以HttpResponse通过调用将返回的实体转换为未压缩的实体
val entity = new GzipDecompressingEntity(response.getEntity)
then proceed with entity.getContentas always.
然后entity.getContent像往常一样继续。

Here is the sample scala code which uses java apache-http-client library
这是使用 java apache-http-client 库的示例 scala 代码
def createCloseableHttpClient(): CloseableHttpClient = {
val builder: HttpClientBuilder = HttpClientBuilder.create
val closableClient = builder.build()
closableClient
}
def postData(data: String): Unit = {
val entity = EntityBuilder.create()
.setText(data)
.setContentType(ContentType.TEXT_PLAIN)
.gzipCompress()
.build()
val post = new HttpPost(postURL + endPoint)
post.setEntity(entity)
post.setHeader("Content-Type", "application/gzip")
val client = createCloseableHttpClient()
client.execute(post)
client.close()
}

Since 4.1, Apache HttpClients handles request and response compression.
从 4.1 开始，Apache HttpClients 处理请求和响应压缩。
- You don't need to compress request, no need to set any "Accept-Encoding" in request headers.
- It automatically handles response decompression as well, no need to handle Decompression of response.
- Till 4.3 it handles gzip and deflate. You can check
ResponseContentEncodingapi doc here.
- 您不需要压缩请求，不需要在请求头中设置任何“Accept-Encoding”。
- 它也自动处理响应解压，无需处理响应解压。
- 直到 4.3 它处理 gzip 和 deflate。您可以在此处查看
ResponseContentEncodingapi 文档。
Just use:
只需使用：
HttpClients.custom()
which uses:
它使用：
HttpClientBuilder.create()
If you want to check in library goto HttpClientBuilderit uses RequestAcceptEncoding& ResponseContentEncoding
如果你想签入库 gotoHttpClientBuilder它使用RequestAcceptEncoding&ResponseContentEncoding
You can disable it through "disableContentCompression()"
您可以通过“disableContentCompression()”禁用它
HttpClient httpClient = HttpClients.custom()
.setConnectionManager(cm)
.disableContentCompression() //this disables compression
.build();
Please make sure if you add any interceptor it can override that, use it carefully.
请确保如果您添加任何拦截器，它可以覆盖它，请谨慎使用它。
HttpClient httpClient = HttpClients.custom()
.setConnectionManager(cm)
.setHttpProcessor(httpprocessor) //this interceptor can override your compression.
.build();
