View In Hierarchy

An object representing an HTTP response received from an HTTP server.
Present Since
11.1
Method deliver​Body Register an IProtocol provider to receive the response body.
Method set​Previous​Response Set the reference to the previous IResponse.
Attribute code The HTTP status code of this response, as a int.
Attribute headers The HTTP response Headers of this response.
Attribute length The int number of bytes expected to be in the body of this response or UNKNOWN_LENGTH if the server did not indicate how many bytes to expect. For HEAD responses, this will be 0; if the response includes a Content-Length header, it will be available in headers.
Attribute phrase The HTTP reason phrase of this response, as a str.
Attribute previous​Response The previous IResponse from a redirect, or None if there was no previous response. This can be used to walk the response or request history for redirections.
Attribute request The IClientRequest that resulted in this response.
Attribute version A three-tuple describing the protocol and protocol version of the response. The first element is of type str, the second and third are of type int. For example, (b'HTTP', 1, 1).
def deliverBody(protocol): (source)

Register an IProtocol provider to receive the response body.

The protocol will be connected to a transport which provides IPushProducer. The protocol's connectionLost method will be called with:

  • ResponseDone, which indicates that all bytes from the response have been successfully delivered.
  • PotentialDataLoss, which indicates that it cannot be determined if the entire response body has been delivered. This only occurs when making requests to HTTP servers which do not set Content-Length or a Transfer-Encoding in the response.
  • ResponseFailed, which indicates that some bytes from the response were lost. The reasons attribute of the exception may provide more specific indications as to why.
def setPreviousResponse(response): (source)

Set the reference to the previous IResponse.

The value of the previous response can be read via IResponse.previousResponse.
