|
|
This module provides a minimal implementation of client side of the
|
|
the Gopher protocol. It is used by the module \code{urllib} to handle
|
|
URLs that use the Gopher protocol.
|
|
|
|
The module defines the following functions:
|
|
|
|
\begin{funcdesc}{send_selector}{selector, host\optional{, port}}
|
|
Send a \var{selector} string to the gopher server at \var{host} and
|
|
\var{port} (default \code{70}). Returns an open file object from
|
|
which the returned document can be read.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{send_query}{selector, query, host\optional{, port}}
|
|
Send a \var{selector} string and a \var{query} string to a gopher
|
|
server at \var{host} and \var{port} (default \code{70}). Returns an
|
|
open file object from which the returned document can be read.
|
|
\end{funcdesc}
|
|
|
|
Note that the data returned by the Gopher server can be of any type,
|
|
depending on the first character of the selector string. If the data
|
|
is text (first character of the selector is \samp{0}), lines are
|
|
terminated by CRLF, and the data is terminated by a line consisting of
|
|
a single \samp{.}, and a leading \samp{.} should be stripped from
|
|
lines that begin with \samp{..}. Directory listings (first character
|
|
of the selector is \samp{1}) are transferred using the same protocol.
