t.i.e.clientFromString(reactor, description) : function documentation

Part of twisted.internet.endpoints View Source

Construct a client endpoint from a description string.

Client description strings are much like server description strings, although they take all of their arguments as keywords, aside from host and port.

You can create a TCP client endpoint with the 'host' and 'port' arguments, like so:

   clientFromString(reactor, "tcp:host=www.example.com:port=80")

or, without specifying host and port keywords:

   clientFromString(reactor, "tcp:www.example.com:80")

Or you can specify only one or the other, as in the following 2 examples:

   clientFromString(reactor, "tcp:host=www.example.com:80")
   clientFromString(reactor, "tcp:www.example.com:port=80")

or an SSL client endpoint with those arguments, plus the arguments used by the server SSL, for a client certificate:

   clientFromString(reactor, "ssl:web.example.com:443:"

to specify your certificate trust roots, you can identify a directory with PEM files in it with the caCertsDir argument:

   clientFromString(reactor, "ssl:host=web.example.com:port=443:"

You can create a UNIX client endpoint with the 'path' argument and optional 'lockfile' and 'timeout' arguments:

   clientFromString(reactor, "unix:path=/var/foo/bar:lockfile=1:timeout=9")

or, with the path as a positional argument with or without optional arguments as in the following 2 examples:

   clientFromString(reactor, "unix:/var/foo/bar")
   clientFromString(reactor, "unix:/var/foo/bar:lockfile=1:timeout=9")

This function is also extensible; new endpoint types may be registered as IStreamClientEndpointStringParser plugins. See that interface for more information.

ParametersreactorThe client endpoint will be constructed with this reactor.
descriptionThe strports description to parse.
ReturnsA new endpoint which can be used to connect with the parameters given by by description. (type: IStreamClientEndpoint)
