      • execute

        public CloseableHttpResponse execute​(HttpHost target,
                                             HttpRequest request,
                                             HttpContext context)
                                      throws java.io.IOException,
                                             ClientProtocolException
        Executes HTTP request 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:
        java.io.IOException - in case of a problem or the connection was aborted
        ClientProtocolException - in case of an http protocol error

                      throws java.io.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.

        request - the request to execute
        responseHandler - the response handler
        Returns:
        the response object as generated by the response handler.
        Throws:
        java.io.IOException - in case of a problem or the connection was aborted
