Class DecompressingHttpClient

java.lang.Object
  org.apache.http.impl.client.DecompressingHttpClient

All Implemented Interfaces:

HttpClient

Deprecated. (4.3) use HttpClientBuilder

@Deprecated
public class DecompressingHttpClient
extends Object
implements HttpClient

Decorator adding support for compressed responses. This class sets the Accept-Encoding header on requests to indicate support for the gzip and deflate compression schemes; it then checks the Content-Encoding header on the response to uncompress any compressed response bodies. The InputStream of the entity will contain the uncompressed content.

N.B. Any upstream clients of this class need to be aware that this effectively obscures visibility into the length of a server response body, since the Content-Length header will correspond to the compressed entity length received from the server, but the content length experienced by reading the response body may be different (hopefully higher!).

That said, this decorator is compatible with the CachingHttpClient in that the two decorators can be added in either order and still have cacheable responses be cached.

Since:

4.2

Constructor Detail

DecompressingHttpClient

public DecompressingHttpClient()

Deprecated.

Constructs a decorator to ask for and handle compressed entities on the fly.

DecompressingHttpClient

public DecompressingHttpClient(HttpClient backend)

Deprecated.

Constructs a decorator to ask for and handle compressed entities on the fly.

Parameters:

backend - the HttpClient to use for actually issuing requests

Method Detail

getParams

public org.apache.http.params.HttpParams getParams()

Deprecated.

Description copied from interface: HttpClient

Obtains the parameters for this client. These parameters will become defaults for all requests being executed with this client, and for the parameters of dependent objects in this client.

Specified by:

getParams in interface HttpClient

Returns:

the default parameters

getConnectionManager

public ClientConnectionManager getConnectionManager()

Deprecated.

Description copied from interface: HttpClient

Obtains the connection manager used by this client.

Specified by:

getConnectionManager in interface HttpClient

Returns:

the connection manager

execute

public org.apache.http.HttpResponse execute(HttpUriRequest request)
                                     throws IOException,
                                            ClientProtocolException

Deprecated.

Description copied from interface: HttpClient

Executes HTTP request using the default context.

Specified by:

execute in interface HttpClient

Parameters:

request - the request to execute

Returns:

the response to the request. This is always a final response, never an intermediate response with an 1xx status code. Whether redirects or authentication challenges will be returned or handled automatically depends on the implementation and configuration of this client.

Throws:

IOException - in case of a problem or the connection was aborted

ClientProtocolException - in case of an http protocol error

getHttpClient

public HttpClient getHttpClient()

Deprecated.

Gets the HttpClient to issue request.

Returns:

the HttpClient to issue request

execute

public org.apache.http.HttpResponse execute(HttpUriRequest request,

Specified by:

execute in interface HttpClient

Parameters:

request - the request to execute

context - the context to use for the execution, or null to use the default context

Returns:
