Interface HttpClient

All Known Implementing Classes:
AbstractHttpClient, AndroidHttpClient, DefaultHttpClient

public interface HttpClient

Interface for an HTTP client. HTTP clients encapsulate a smorgasbord of objects required to execute HTTP requests while handling cookies, authentication, connection management, and other features. Thread safety of HTTP clients depends on the implementation and configuration of the specific client.

Since:
4.0

Method Detail

getParams

HttpParams getParams()
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.

Returns:
the default parameters

getConnectionManager

ClientConnectionManager getConnectionManager()

Returns:
the connection manager

execute

HttpResponse execute(HttpUriRequest request)
                     throws IOException,
                            ClientProtocolException
Executes a request using the default context.

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

Executes a request using the given context. The route to the target will be determined by the HTTP client.

Parameters:
request - the request to execute
context - the context to use for the execution, or null to use the default context
