t.w.c.HTTPPageGetter(http.HTTPClient) : class documentation

Part of twisted.web.client View Source View In Hierarchy

Known subclasses: twisted.web.client.HTTPPageDownloader

Gets a resource via HTTP, then quits.

Typically used with HTTPClientFactory. Note that this class does not, by itself, do anything with the response. If you want to download a resource into a file, use HTTPPageDownloader instead.

Method connectionMade Called when a connection is made.
Method handleHeader Called every time a header is received. Stores the header information as key-value pairs in the headers attribute.
Method handleStatus Called when the status-line is received.
Method handleEndHeaders Called when all headers have been received.
Method handleStatus_200 Undocumented
Method handleStatusDefault Undocumented
Method handleStatus_301 Undocumented
Method handleStatus_302 Undocumented
Method handleStatus_303 Undocumented
Method connectionLost When the connection used to issue the HTTP request is closed, notify the factory if we have not already, so it can produce a result.
Method handleResponse Undocumented
Method timeout Undocumented
Instance Variable _completelyDone A boolean indicating whether any further requests are necessary after this one completes in order to provide a result to self.factory.deferred. If it is False, then a redirect is going to be followed. Otherwise, this protocol's connection is the last one before firing the result Deferred. This is used to make sure the result Deferred is only fired after the connection is cleaned up.

Inherited from HTTPClient:

Instance Variable length The length of the request body in bytes. (type: int)
Instance Variable firstLine Are we waiting for the first header line? (type: bool)
Method sendCommand Undocumented
Method sendHeader Undocumented
Method endHeaders Undocumented
Method extractHeader Given a complete HTTP header, extract the field name and value and process the header.
Method lineReceived Parse the status line and headers for an HTTP request.
Method handleResponseEnd The response has been completely received.
Method handleResponsePart Undocumented
Method rawDataReceived Override this for when raw data is received.
Instance Variable __buffer The buffer that stores the response to the HTTP request. (type: A StringIO object.)
Instance Variable _header Part or all of an HTTP request header. (type: bytes)

Inherited from LineReceiver (via HTTPClient):

Class Variable delimiter The line-ending delimiter to use. By default this is b'\r\n'.
Class Variable 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.
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 HTTPClient, LineReceiver):

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via HTTPClient, LineReceiver, Protocol):

Method makeConnection Make a connection to a transport and a server.

Inherited from _PauseableMixin (via HTTPClient, LineReceiver):

Method pauseProducing Undocumented
Method resumeProducing Undocumented
Method stopProducing Undocumented
_completelyDone =
A boolean indicating whether any further requests are necessary after this one completes in order to provide a result to self.factory.deferred. If it is False, then a redirect is going to be followed. Otherwise, this protocol's connection is the last one before firing the result Deferred. This is used to make sure the result Deferred is only fired after the connection is cleaned up.
def connectionMade(self): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.web.http.HTTPClient.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 handleHeader(self, key, value): (source)
overrides twisted.web.http.HTTPClient.handleHeader
Called every time a header is received. Stores the header information as key-value pairs in the headers attribute.
ParameterskeyAn HTTP header field name. (type: str)
valueAn HTTP header field value. (type: str)
def handleStatus(self, version, status, message): (source)
overrides twisted.web.http.HTTPClient.handleStatus
Called when the status-line is received.
Parametersversione.g. 'HTTP/1.0'
statuse.g. '200' (type: bytes)
messagee.g. 'OK'
def handleEndHeaders(self): (source)
overrides twisted.web.http.HTTPClient.handleEndHeaders
Called when all headers have been received.
def handleStatus_200(self): (source)
overridden in twisted.web.client.HTTPPageDownloader

def connectionLost(self, reason): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.web.http.HTTPClient.connectionLost
When the connection used to issue the HTTP request is closed, notify the factory if we have not already, so it can produce a result.
