doExecute

protected abstract CloseableHttpResponse doExecute(HttpHost target,
                              HttpRequest request,
                              HttpContext context)

                                                   ClientProtocolException

Throws:

IOException

ClientProtocolException

execute

public CloseableHttpResponse execute(HttpHost target,
                            HttpRequest request,
                            HttpContext context)
                              throws IOException,
                                     ClientProtocolException

Executes a request to the target using the given context.

Specified by:

execute in interface HttpClient

Parameters:

target - the target host for the request. Implementations may accept null if they can still determine a route, for example to a default target or by inspecting the request.

request - the request to execute

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

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

execute

public CloseableHttpResponse execute(HttpUriRequest request,
                            HttpContext context)
                              throws IOException,
                                     ClientProtocolException

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

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:

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

execute

public CloseableHttpResponse execute(HttpUriRequest request)
                              throws IOException,
                                     ClientProtocolException

Executes a 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

execute

public CloseableHttpResponse execute(HttpHost target,
                            HttpRequest request)

Executes a request to the target using the default context.

Specified by:

execute in interface HttpClient

Parameters:

target - the target host for the request. Implementations may accept null if they can still determine a route, for example to a default target or by inspecting the request.

request - the request to execute

Returns:

          throws IOException,
                 ClientProtocolException

Executes a request using the default context and processes the response using the given response handler. The content entity associated with the response is fully consumed and the underlying connection is released back to the connection manager automatically in all cases relieving individual ResponseHandlers from having to manage resource deallocation internally.

Specified by:

execute in interface HttpClient

Parameters:

request - the request to execute

responseHandler - the response handler

Returns:

the response object as generated by the response handler.

Throws:

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