class documentation

class HTTPClient(basic.LineReceiver): (source)

Known subclasses: twisted.protocols.shoutcast.ShoutcastClient, twisted.web.client.HTTPPageGetter, twisted.web.proxy.ProxyClient, twisted.web.xmlrpc.QueryProtocol

View In Hierarchy

A client for HTTP 1.0.

Notes: You probably want to send a 'Host' header with the name of the site you're connecting to, in order to not break name based virtual hosting.

Method	`connectionLost`	Called when the connection is shut down.
Method	`connectionMade`	Called when a connection is made.
Method	`endHeaders`	Undocumented
Method	`extractHeader`	Given a complete HTTP header, extract the field name and value and process the header.
Method	`handleEndHeaders`	Called when all headers have been received.
Method	`handleHeader`	Called every time a header is received.
Method	`handleResponseEnd`	The response has been completely received.
Method	`handleResponsePart`	Undocumented
Method	`handleStatus`	Called when the status-line is received.
Method	`lineReceived`	Parse the status line and headers for an HTTP request.
Method	`rawDataReceived`	Override this for when raw data is received.
Method	`sendCommand`	Undocumented
Method	`sendHeader`	Undocumented
Instance Variable	`firstLine`	Are we waiting for the first header line?
Instance Variable	`length`	The length of the request body in bytes.
Instance Variable	`__buffer`	The buffer that stores the response to the HTTP request.
Instance Variable	`_header`	Part or all of an HTTP request header.

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	`lineLengthExceeded`	Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.
Method	`sendLine`	Sends a line to the other end of the connection.
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.
Constant	`MAX_LENGTH`	The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Class Variable	`delimiter`	The line-ending delimiter to use. By default this is `b'\r\n'`.
Instance Variable	`line_mode`	Undocumented
Instance Variable	`_buffer`	Undocumented
Instance Variable	`_busyReceiving`	Undocumented

Inherited from Protocol (via LineReceiver):

Method	`logPrefix`	Return a prefix matching the class name, to identify log messages related to this protocol instance.
Class Variable	`factory`	Undocumented

Inherited from BaseProtocol (via LineReceiver, Protocol):

Method	`makeConnection`	Make a connection to a transport and a server.
Instance Variable	`connected`	Undocumented
Instance Variable	`transport`	Undocumented

Inherited from _PauseableMixin (via LineReceiver):

Method	`pauseProducing`	Undocumented
Method	`resumeProducing`	Undocumented
Method	`stopProducing`	Undocumented
Instance Variable	`paused`	Undocumented

def connectionLost(self, reason): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.Protocol.connectionLost

overridden in twisted.web.client.HTTPPageGetter, twisted.web.xmlrpc.QueryProtocol

Called when the connection is shut down.

Clear any circular references here, and any external references to this Protocol. The connection has been closed.

Parameters
reason:`twisted.python.failure.Failure`	Undocumented

def connectionMade(self): (source)

from twisted.internet.interfaces.IProtocol

overrides twisted.internet.protocol.BaseProtocol.connectionMade

overridden in twisted.protocols.shoutcast.ShoutcastClient, twisted.web.client.HTTPPageGetter, twisted.web.proxy.ProxyClient, twisted.web.xmlrpc.QueryProtocol

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 endHeaders(self): (source)

Undocumented

def extractHeader(self, header): (source)

Given a complete HTTP header, extract the field name and value and process the header.

Parameters
header:`bytes`	a complete HTTP request header of the form 'field-name: value'.

def handleEndHeaders(self): (source)

overridden in twisted.protocols.shoutcast.ShoutcastClient, twisted.web.client.HTTPPageGetter

Called when all headers have been received.

def handleHeader(self, key, val): (source)

overridden in twisted.protocols.shoutcast.ShoutcastClient, twisted.web.client.HTTPPageGetter, twisted.web.proxy.ProxyClient

Called every time a header is received.

def handleResponseEnd(self): (source)

overridden in twisted.web.client.HTTPPageDownloader, twisted.web.proxy.ProxyClient

The response has been completely received.

This callback may be invoked more than once per request.

def handleResponsePart(self, data): (source)

overridden in twisted.web.client.HTTPPageDownloader, twisted.web.proxy.ProxyClient

Undocumented

def handleStatus(self, version, status, message): (source)

overridden in twisted.web.client.HTTPPageGetter, twisted.web.proxy.ProxyClient, twisted.web.xmlrpc.QueryProtocol

Called when the status-line is received.

Parameters
version	e.g. 'HTTP/1.0'
status:`bytes`	e.g. '200'
message	e.g. 'OK'

def lineReceived(self, line): (source)

overrides twisted.protocols.basic.LineReceiver.lineReceived

overridden in twisted.protocols.shoutcast.ShoutcastClient

Parse the status line and headers for an HTTP request.

Parameters
line:`bytes`	Part of an HTTP request header. Request bodies are parsed in `HTTPClient.rawDataReceived`.

def rawDataReceived(self, data): (source)

overrides twisted.protocols.basic.LineReceiver.rawDataReceived

Override this for when raw data is received.

def sendCommand(self, command, path): (source)

Undocumented

def sendHeader(self, name, value): (source)

Undocumented

firstLine: bool = (source)

Are we waiting for the first header line?

length: int = (source)

The length of the request body in bytes.

__buffer: A BytesIO object. = (source)

The buffer that stores the response to the HTTP request.

_header: bytes = (source)

Part or all of an HTTP request header.
