Part of twisted.web View Source

HTTP client.
Function urlunparse Undocumented
Class PartialDownloadError Page was only partially downloaded, we got disconnected in middle.
Class HTTPPageGetter Gets a resource via HTTP, then quits.
Class HTTPPageDownloader Undocumented
Class HTTPClientFactory Download a given URL.
Class HTTPDownloader Download to a file.
Function getPage Download a web page as a string.
Function downloadPage Download a web page to a file.
Class Response A Response instance describes an HTTP response received from an HTTP server.
Class ResponseDone ResponseDone may be passed to IProtocol.connectionLost on the protocol passed to Response.deliverBody and indicates that the entire response has been delivered.
Class ResponseFailed ResponseFailed indicates that all of the response to a request was not received for some reason.
Class WebClientContextFactory 0 A web context factory which doesn't work because the necessary SSL support is missing.
Class WebClientContextFactory A web context factory which ignores the hostname and port and does no certificate verification.
Class FileBodyProducer FileBodyProducer produces bytes from an input file object incrementally and writes them to a consumer.
Class HTTPConnectionPool A pool of persistent HTTP connections.
Class Agent Agent is a very basic HTTP client. It supports HTTP and HTTPS scheme URIs (but performs no certificate checking by default).
Class ProxyAgent An HTTP agent able to cross HTTP proxies.
Class CookieAgent CookieAgent extends the basic Agent to add RFC-compliant handling of HTTP cookies. Cookies are written to and extracted from a cookielib.CookieJar instance.
Class GzipDecoder A wrapper for a Response instance which handles gzip'ed body.
Class ContentDecoderAgent An Agent wrapper to handle encoded content.
Class RedirectAgent An Agent wrapper which handles HTTP redirects.
Class BrowserLikeRedirectAgent An Agent wrapper which handles HTTP redirects in the same fashion as web browsers.
Function readBody Get the body of an IResponse and return it as a byte string.
Class _URI A URI object.
Function _urljoin No summary
Function _makeGetterFactory Create and connect an HTTP page getting factory.
Class _WebToNormalContextFactory Adapt a web context factory to a normal context factory.
Class _HTTP11ClientFactory A factory for HTTP11ClientProtocol, used by HTTPConnectionPool.
Class _RetryingHTTP11ClientProtocol A wrapper for HTTP11ClientProtocol that automatically retries requests.
Class _AgentBase Base class offering common facilities for Agent-type classes.
Class _FakeUrllib2Request A fake urllib2.Request object for cookielib to work with.
Class _FakeUrllib2Response A fake urllib2.Response object for cookielib to work with.
Class _GzipProtocol A Protocol implementation which wraps another one, transparently decompressing received data.
Class _ReadBodyProtocol Protocol that collects data sent to it.
def urlunparse(parts): (source)
def _urljoin(base, url): (source)
Construct a full ("absolute") URL by combining a "base URL" with another URL. Informally, this uses components of the base URL, in particular the addressing scheme, the network location and (part of) the path, to provide missing components in the relative URL.

Additionally, the fragment identifier is preserved according to the HTTP 1.1 bis draft.

ParametersbaseBase URL. (type: bytes)
urlURL to combine with base. (type: bytes)
ReturnsAn absolute URL resulting from the combination of base and url.
See Alsourlparse.urljoin
def _makeGetterFactory(url, factoryFactory, *args, contextFactory=None, **kwargs): (source)
Create and connect an HTTP page getting factory.

Any additional positional or keyword arguments are used when calling factoryFactory.

ParametersfactoryFactoryFactory factory that is called with url, args and kwargs to produce the getter
contextFactoryContext factory to use when creating a secure connection, defaulting to None
ReturnsThe factory created by factoryFactory
def getPage(url, *args, contextFactory=None, **kwargs): (source)
Download a web page as a string.

Download a page. Return a deferred, which will callback with a page (as a string) or errback with a description of the error.

See HTTPClientFactory to see what extra arguments can be passed.

def downloadPage(url, file, *args, contextFactory=None, **kwargs): (source)
Download a web page to a file.
Parametersfilepath to file on filesystem, or file-like object.

See HTTPDownloader to see what extra args can be passed.

def readBody(response): (source)
Get the body of an IResponse and return it as a byte string.

This is a helper function for clients that don't want to incrementally receive the body of an HTTP response.

ParametersresponseThe HTTP response for which the body will be read. (type: IResponse provider)
ReturnsA Deferred which will fire with the body of the response.
