:mod:`CGIHTTPServer` --- CGI-capable HTTP request handler
|
|
=========================================================
|
|
|
|
.. module:: CGIHTTPServer
|
|
:synopsis: This module provides a request handler for HTTP servers which can run CGI
|
|
scripts.
|
|
.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
|
|
|
|
.. note::
|
|
The :mod:`CGIHTTPServer` module has been merged into :mod:`http.server` in
|
|
Python 3.0. The :term:`2to3` tool will automatically adapt imports when
|
|
converting your sources to 3.0.
|
|
|
|
|
|
The :mod:`CGIHTTPServer` module defines a request-handler class, interface
|
|
compatible with :class:`BaseHTTPServer.BaseHTTPRequestHandler` and inherits
|
|
behavior from :class:`SimpleHTTPServer.SimpleHTTPRequestHandler` but can also
|
|
run CGI scripts.
|
|
|
|
.. note::
|
|
|
|
This module can run CGI scripts on Unix and Windows systems.
|
|
|
|
.. note::
|
|
|
|
CGI scripts run by the :class:`CGIHTTPRequestHandler` class cannot execute
|
|
redirects (HTTP code 302), because code 200 (script output follows) is sent
|
|
prior to execution of the CGI script. This pre-empts the status code.
|
|
|
|
The :mod:`CGIHTTPServer` module defines the following class:
|
|
|
|
|
|
.. class:: CGIHTTPRequestHandler(request, client_address, server)
|
|
|
|
This class is used to serve either files or output of CGI scripts from the
|
|
current directory and below. Note that mapping HTTP hierarchic structure to
|
|
local directory structure is exactly as in
|
|
:class:`SimpleHTTPServer.SimpleHTTPRequestHandler`.
|
|
|
|
The class will however, run the CGI script, instead of serving it as a file, if
|
|
it guesses it to be a CGI script. Only directory-based CGI are used --- the
|
|
other common server configuration is to treat special extensions as denoting CGI
|
|
scripts.
|
|
|
|
The :func:`do_GET` and :func:`do_HEAD` functions are modified to run CGI scripts
|
|
and serve the output, instead of serving files, if the request leads to
|
|
somewhere below the ``cgi_directories`` path.
|
|
|
|
The :class:`CGIHTTPRequestHandler` defines the following data member:
|
|
|
|
|
|
.. attribute:: cgi_directories
|
|
|
|
This defaults to ``['/cgi-bin', '/htbin']`` and describes directories to
|
|
treat as containing CGI scripts.
|
|
|
|
The :class:`CGIHTTPRequestHandler` defines the following methods:
|
|
|
|
|
|
.. method:: do_POST()
|
|
|
|
This method serves the ``'POST'`` request type, only allowed for CGI
|
|
scripts. Error 501, "Can only POST to CGI scripts", is output when trying
|
|
to POST to a non-CGI url.
|
|
|
|
Note that CGI scripts will be run with UID of user nobody, for security reasons.
|
|
Problems with the CGI script will be translated to error 403.
|
|
|
|
For example usage, see the implementation of the :func:`test` function.
