\section{Standard Module \module{poplib}}
|
||||
\stmodindex{poplib}
|
||||
\label{module-poplib}
|
||||
\indexii{POP3}{protocol}
|
||||
|
||||
This module defines a class, \class{POP3}, which encapsulates a
|
||||
connection to an POP3 server and implements protocol as defined in
|
||||
\rfc{1725}. The \class{POP3} class supports both the minmal and
|
||||
optional command sets.
|
||||
|
||||
A single class is provided by the \module{poplib} module:
|
||||
|
||||
\begin{classdesc}{POP3}{host\optional{, port}}
|
||||
This class implements the actual POP3 protocol. The connection is
|
||||
created when the instance is initialized.
|
||||
If \var{port} is omitted, the standard POP3 port (110) is used.
|
||||
\end{classdesc}
|
||||
|
||||
One exception is defined as attributes of the \module{poplib} module:
|
||||
|
||||
\begin{excdesc}{error_proto}
|
||||
Exception raised on any errors. The reason for the exception is
|
||||
passed to the constructor as a string.
|
||||
\end{excdesc}
|
||||
|
||||
|
||||
\subsection{POP3 Objects}
|
||||
\label{pop3-objects}
|
||||
|
||||
All POP3 commands are represented by methods of the same name,
|
||||
in lower-case.
|
||||
|
||||
Most commands return the response text sent by the server.
|
||||
|
||||
An \class{POP3} instance has the following methods:
|
||||
|
||||
|
||||
\begin{methoddesc}{getwelcome}{}
|
||||
Returns the greeting string sent by the POP3 server.
|
||||
\end{methoddesc}
|
||||
|
||||
|
||||
\begin{methoddesc}{user}{username}
|
||||
Send user commad, response should indicate that a password is required.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{pass_}{password}
|
||||
Send password, response includes message count and mailbox size.
|
||||
Note: the mailbox on the server is locked until \method{quit()} is
|
||||
called.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{apop}{user, secret}
|
||||
Use the more secure APOP authentication to log into the POP3 server.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{rpop}{user}
|
||||
Use RPOP authentication (similar to UNIX r-commands) to log into POP3 server.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{stat}{}
|
||||
Get mailbox status. The result is a tuple of 2 integers:
|
||||
\code{(\var{message count}, \var{mailbox size})}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{list}{\optional{which}}
|
||||
Request message list, result is in the form
|
||||
\code{['response', ['mesg_num octets', ...]]}. If \var{which} is
|
||||
set, it is the message to list.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{retr}{which}
|
||||
Retrieve whole message number \var{which}. Result is in form
|
||||
\code{['response', ['line', ...], octets]}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{dele}{which}
|
||||
Delete message number \var{which}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{rset}{}
|
||||
Remove any deletion marks for the mailbox.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{noop}{}
|
||||
Do nothing. Might be used as a keep-alive.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{quit}{}
|
||||
Signoff: commit changes, unlock mailbox, drop connection.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{top}{which, howmuch}
|
||||
Retrieves the message header plus \var{howmuch} lines of the message
|
||||
after the header of message number \var{which}. Result is in form
|
||||
\code{['response', ['line', ...], octets]}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{uidl}{\optional{which}}
|
||||
Return message digest (unique id) list.
|
||||
If \var{which} is specified, result contains unique id for that
|
||||
message, otherwise result is list \code{['response',
|
||||
['mesgnum uid', ...], octets]}.
|
||||
\end{methoddesc}
|
||||
|
||||
|
||||
\subsection{POP3 Example}
|
||||
\label{pop3-example}
|
||||
|
||||
Here is a minimal example (without error checking) that opens a
|
||||
mailbox and retrieves and prints all messages:
|
||||
|
||||
\begin{verbatim}
|
||||
import getpass, poplib, string
|
||||
|
||||
M = poplib.POP3('localhost')
|
||||
M.user(getpass.getuser())
|
||||
M.pass(getpass.getpass())
|
||||
numMessages = len(M.list()[1])
|
||||
for i in range(numMessages):
|
||||
for j in M.retr(i+1)[1]:
|
||||
sys.stdout.write(j)
|
||||
\end{verbatim}
|
||||
|
||||
At the end of the module, there is a test section that contains a more
|
||||
extensive example of usage.
