twisted.web.http

HyperText Transfer Protocol implementation.

This is the basic server-side protocol implementation used by the Twisted Web server. It can parse HTTP 1.0 requests and supports many HTTP 1.1 features as well. Additionally, some functionality implemented here is also useful for HTTP clients (such as the chunked encoding parser).

Variable	CACHED	A marker value to be returned from cache-related request methods to indicate to the caller that a cached response will be usable and no response body should be generated.
Variable	FOUND	An HTTP response code indicating a temporary redirect.
Variable	NOT_MODIFIED	An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an If-Modified-Since header is present in the request) has succeeded. This indicates a response body cached by the client can be used.
Variable	PRECONDITION_FAILED	An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an If-None-Match header is present in the request) has failed. This should typically indicate that the server has not taken the requested action.
Function	urlparse	Parse an URL into six components.
Function	parse_qs	Like `cgi.parse_qs`, but with support for parsing byte strings on Python 3.
Function	datetimeToString	Convert seconds since epoch to HTTP datetime string.
Function	datetimeToLogString	Convert seconds since epoch to log datetime string.
Function	timegm	Convert time tuple in GMT to seconds since epoch, GMT
Function	stringToDatetime	Convert an HTTP date string (one of three formats) to seconds since epoch.
Function	toChunk	Convert string to a chunk.
Function	fromChunk	Convert chunk to string.
Function	parseContentRange	Parse a content-range header into (start, end, realLength).
Class	StringTransport	I am a StringIO wrapper that conforms for the transport API. I support the `writeSequence' method.
Class	HTTPClient	A client for HTTP 1.0.
Class	Request	A HTTP request.
Class	PotentialDataLoss	No summary
Class	HTTPChannel	A receiver for HTTP requests.
Function	combinedLogFormatter
Function	proxiedLogFormatter
Class	HTTPFactory	Factory for HTTP server.
Function	_parseHeader	Undocumented
Interface	_IDeprecatedHTTPChannelToRequestInterface	The interface `HTTPChannel` expects of `Request`.
Function	_getContentFile	Get a writeable file-like object to which request content can be written.
Class	_DataLoss	No summary
Class	_MalformedChunkedDataError	No summary
Class	_IdentityTransferDecoder	Protocol for accumulating bytes up to a specified length. This handles the case where no Transfer-Encoding is specified.
Class	_ChunkedTransferDecoder	No summary
Class	_NoPushProducer	A no-op version of `interfaces.IPushProducer`, used to abstract over the possibility that a `HTTPChannel` transport does not provide `IPushProducer`.
Function	_escape	Return a string like python repr, but always escaped as if surrounding quotes were double quotes.
Class	_XForwardedForAddress	`IAddress` which represents the client IP to log for a request, as gleaned from an X-Forwarded-For header.
Class	_XForwardedForRequest	Add a layer on top of another request that only uses the value of an X-Forwarded-For header as the result of `getClientAddress`.
Class	_GenericHTTPChannelProtocol	A proxy object that wraps one of the HTTP protocol objects, and switches between them depending on TLS negotiated protocol.
Function	_genericHTTPChannelProtocolFactory	Returns an appropriately initialized _GenericHTTPChannelProtocol.

CACHED =

A marker value to be returned from cache-related request methods to indicate to the caller that a cached response will be usable and no response body should be generated.

FOUND =

An HTTP response code indicating a temporary redirect.

NOT_MODIFIED =

An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an If-Modified-Since header is present in the request) has succeeded. This indicates a response body cached by the client can be used.

PRECONDITION_FAILED =

An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an If-None-Match header is present in the request) has failed. This should typically indicate that the server has not taken the requested action.

def _parseHeader(line):

Undocumented

def urlparse(url):

Parse an URL into six components.

This is similar to urlparse.urlparse, but rejects unicode input and always produces bytes output.

Returns	The scheme, net location, path, params, query string, and fragment of the URL - all as `bytes`. (type: `ParseResultBytes`)
Raises	TypeError	The given url was a `unicode` string instead of a `bytes`.

def parse_qs(qs, keep_blank_values=0, strict_parsing=0):

Like cgi.parse_qs, but with support for parsing byte strings on Python 3.

def datetimeToString(msSinceEpoch=None):

Convert seconds since epoch to HTTP datetime string.

Returns (type: bytes)

def datetimeToLogString(msSinceEpoch=None):

Convert seconds since epoch to log datetime string.

Returns (type: str)

def timegm(year, month, day, hour, minute, second):

Convert time tuple in GMT to seconds since epoch, GMT

def stringToDatetime(dateString):

Convert an HTTP date string (one of three formats) to seconds since epoch.

def toChunk(data):

Convert string to a chunk.

Returns a tuple of bytes representing the chunked encoding of data

def fromChunk(data):

Convert chunk to string.

Returns	tuple of (result, remaining) - both `bytes`.
Raises	ValueError	If the given data is not a correctly formatted chunked byte string.

def parseContentRange(header):

Parse a content-range header into (start, end, realLength).

realLength might be None if real length is not known ('*').

def _getContentFile(length):

Get a writeable file-like object to which request content can be written.

def _escape(s):

Return a string like python repr, but always escaped as if surrounding quotes were double quotes.

Parameters	s	The string to escape. (type: `bytes` or `unicode`)
Returns	An escaped string. (type: `unicode`)

@provider(IAccessLogFormatter)
def combinedLogFormatter(timestamp, request):

Returns	A combined log formatted log line for the given request.
See Also	`IAccessLogFormatter`

@provider(IAccessLogFormatter)
def proxiedLogFormatter(timestamp, request):

Returns	A combined log formatted log line for the given request but use the value of the X-Forwarded-For header as the value for the client IP address.
See Also	`IAccessLogFormatter`

def _genericHTTPChannelProtocolFactory(self):

Returns an appropriately initialized _GenericHTTPChannelProtocol.
