twisted.web._newclient

The way to use the functionality provided by this module is to:

Connect a HTTP11ClientProtocol to an HTTP server
Create a Request with the appropriate data
Pass the request to HTTP11ClientProtocol.request
The returned Deferred will fire with a Response object
Create a IProtocol provider which can handle the response body
Connect it to the response with Response.deliverBody
When the protocol's connectionLost method is called, the response is complete. See Response.deliverBody for details.

Various other classes in this module support this usage:

HTTPParser is the basic HTTP parser. It can handle the parts of HTTP which are symmetric between requests and responses.
HTTPClientParser extends HTTPParser to handle response-specific parts of HTTP. One instance is created for each request to parse the corresponding response.

Class	BadHeaders	Headers passed to `Request` were in some way invalid.
Class	ExcessWrite	The body `IBodyProducer` for a request tried to write data after indicating it had finished writing data.
Class	ParseError	Some received data could not be parsed.
Class	BadResponseVersion	The version string in a status line was unparsable.
Class	ConnectionAborted	The connection was explicitly aborted by application code.
Class	WrongBodyLength	An `IBodyProducer` declared the number of bytes it was going to produce (via its `length` attribute) and then produced a different number of bytes.
Class	RequestNotSent	No summary
Class	HTTPParser	`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.
Class	HTTPClientParser	An HTTP parser which only handles HTTP responses.
Class	Request	A `Request` instance describes an HTTP request to be sent to an HTTP server.
Class	LengthEnforcingConsumer	An `IConsumer` proxy which enforces an exact length requirement on the total data written to it.
Function	makeStatefulDispatcher	No summary
Class	ChunkedEncoder	Helper object which exposes `IConsumer` on top of `HTTP11ClientProtocol` for streaming request bodies to the server.
Class	TransportProxyProducer	An `twisted.internet.interfaces.IPushProducer` implementation which wraps another such thing and proxies calls to it until it is told to stop.
Class	HTTP11ClientProtocol	`HTTP11ClientProtocol` is an implementation of the HTTP 1.1 client protocol. It supports as few features as possible.
Class	_WrapperException	`_WrapperException` is the base exception type for exceptions which include one or more other exceptions as the low-level causes.
Function	_callAppFunction	Call `function`. If it raises an exception, log it with a minimal description of the source.
Function	_ensureValidMethod	An HTTP method is an HTTP token, which consists of any visible ASCII character that is not a delimiter (i.e. one of `"(),/:;<=>?@[\]{}`.)
Function	_ensureValidURI	A valid URI cannot contain control characters (i.e., characters between 0-32, inclusive and 127) or non-ASCII characters (i.e., characters with values between 128-255, inclusive).

def _callAppFunction(function):

Call function. If it raises an exception, log it with a minimal description of the source.

Returns None

def _ensureValidMethod(method):

An HTTP method is an HTTP token, which consists of any visible ASCII character that is not a delimiter (i.e. one of "(),/:;<=>?@[\]{}.)

Parameters	method	the method to check (type: `bytes`)
Returns	the method if it is valid (type: `bytes`)
Raises	ValueError	if the method is not valid
See Also	https://tools.ietf.org/html/rfc7230#section-3.1.1, https://tools.ietf.org/html/rfc7230#section-3.2.6, https://tools.ietf.org/html/rfc5234#appendix-B.1

def _ensureValidURI(uri):

A valid URI cannot contain control characters (i.e., characters between 0-32, inclusive and 127) or non-ASCII characters (i.e., characters with values between 128-255, inclusive).

Parameters	uri	the URI to check (type: `bytes`)
Returns	the URI if it is valid (type: `bytes`)
Raises	ValueError	if the URI is not valid
See Also	https://tools.ietf.org/html/rfc3986#section-3.3, https://tools.ietf.org/html/rfc3986#appendix-A, https://tools.ietf.org/html/rfc5234#appendix-B.1

def makeStatefulDispatcher(name, template):

Given a dispatch name and a function, return a function which can be used as a method and which, when called, will call another method defined on the instance and return the result. The other method which is called is determined by the value of the _state attribute of the instance.

Parameters	name	A string which is used to construct the name of the subsidiary method to invoke. The subsidiary method is named like `'_%s_%s' % (name, _state)`.
	template	A function object which is used to give the returned function a docstring.
Returns	The dispatcher function.
