twisted.web._newclient.HTTPParser : API documentation

HTTPParser handles the parsing side of HTTP processing. With a suitable subclass, it can parse either the client side or the server side of the connection.

Instance Variables	headers	All of the non-connection control message headers yet received.
	state	State indicator for the response parsing state machine. One of `STATUS`, `HEADER`, `BODY`, `DONE`.
	_partialHeader	`None` or a `list` of the lines of a multiline header while that header is being received.

Method	connectionMade	Called when a connection is made.
Method	switchToBodyMode	Switch to body parsing mode - interpret any more bytes delivered as part of the message body and deliver them to the given decoder.
Method	lineReceived	Handle one line from a response.
Method	rawDataReceived	Pass data from the message body to the body decoder object.
Method	isConnectionControlHeader	Return `True` if the given lower-cased name is the name of a connection control header (rather than an entity header).
Method	statusReceived	Callback invoked whenever the first line of a new message is received. Override this.
Method	headerReceived	Store the given header in `self.headers`.
Method	allHeadersReceived	Callback invoked after the last header is passed to `headerReceived`. Override this to change to the `BODY` or `DONE` state.

Inherited from LineReceiver:

Method	clearLineBuffer	Clear buffered data.
Method	dataReceived	Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method	setLineMode	Sets the line-mode of this receiver.
Method	setRawMode	Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.
Method	sendLine	Sends a line to the other end of the connection.
Method	lineLengthExceeded	Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Inherited from Protocol (via LineReceiver):

Method

connectionLost

Called when the connection is shut down.

Inherited from BaseProtocol (via LineReceiver, Protocol):

Method

makeConnection

Make a connection to a transport and a server.

Inherited from _PauseableMixin (via LineReceiver):

Method	pauseProducing	Undocumented
Method	resumeProducing	Undocumented
Method	stopProducing	Undocumented

def connectionMade(self): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

Called when a connection is made.

This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.

def isConnectionControlHeader(self, name): (source)

overridden in twisted.web._newclient.HTTPClientParser

Return True if the given lower-cased name is the name of a connection control header (rather than an entity header).

According to RFC 2616, section 14.10, the tokens in the Connection header are probably relevant here. However, I am not sure what the practical consequences of either implementing or ignoring that are. So I leave it unimplemented for the time being.

def allHeadersReceived(self): (source)

overridden in twisted.web._newclient.HTTPClientParser

Callback invoked after the last header is passed to headerReceived. Override this to change to the BODY or DONE state.
