twisted.protocols.haproxy._v1parser.V1Parser

PROXY protocol version one header parser.

Version one of the PROXY protocol is a human readable format represented by a single, newline delimited binary string that contains all of the relevant source and destination data.

def __init__(self):

Undocumented

def feed(self, data):

Consume a chunk of data and attempt to parse it.

Parameters	data	A bytestring. (type: `bytes`)
Returns	A two-tuple containing, in order, a `_interfaces.IProxyInfo` and any bytes fed to the parser that followed the end of the header. Both of these values are None until a complete header is parsed.
Raises	InvalidProxyHeader	If the bytes fed to the parser create an invalid PROXY header.

@classmethod
def parse(cls, line):

Parse a bytestring as a full PROXY protocol header line.

Parameters	line	A bytestring that represents a valid HAProxy PROXY protocol header line. (type: bytes)
Returns	A `_interfaces.IProxyInfo` containing the parsed data.
Raises	InvalidProxyHeader	If the bytestring does not represent a valid PROXY header.
	InvalidNetworkProtocol	When no protocol can be parsed or is not one of the allowed values.
	MissingAddressData	When the protocol is TCP* but the header does not contain a complete set of addresses and ports.

Method	__init__	Undocumented
Method	feed	Consume a chunk of data and attempt to parse it.
Class Method	parse	Parse a bytestring as a full PROXY protocol header line.
