:mod:`SimpleHTTPServer` --- Simple HTTP request handler ======================================================= .. module:: SimpleHTTPServer :synopsis: This module provides a basic request handler for HTTP servers. .. sectionauthor:: Moshe Zadka .. note:: The :mod:`SimpleHTTPServer` 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:`SimpleHTTPServer` module defines a single class, :class:`SimpleHTTPRequestHandler`, which is interface-compatible with :class:`BaseHTTPServer.BaseHTTPRequestHandler`. The :mod:`SimpleHTTPServer` module defines the following class: .. class:: SimpleHTTPRequestHandler(request, client_address, server) This class serves files from the current directory and below, directly mapping the directory structure to HTTP requests. A lot of the work, such as parsing the request, is done by the base class :class:`BaseHTTPServer.BaseHTTPRequestHandler`. This class implements the :func:`do_GET` and :func:`do_HEAD` functions. The following are defined as class-level attributes of :class:`SimpleHTTPRequestHandler`: .. attribute:: server_version This will be ``"SimpleHTTP/" + __version__``, where ``__version__`` is defined at the module level. .. attribute:: extensions_map A dictionary mapping suffixes into MIME types. The default is signified by an empty string, and is considered to be ``application/octet-stream``. The mapping is used case-insensitively, and so should contain only lower-cased keys. The :class:`SimpleHTTPRequestHandler` class defines the following methods: .. method:: do_HEAD() This method serves the ``'HEAD'`` request type: it sends the headers it would send for the equivalent ``GET`` request. See the :meth:`do_GET` method for a more complete explanation of the possible headers. .. method:: do_GET() The request is mapped to a local file by interpreting the request as a path relative to the current working directory. If the request was mapped to a directory, the directory is checked for a file named ``index.html`` or ``index.htm`` (in that order). If found, the file's contents are returned; otherwise a directory listing is generated by calling the :meth:`list_directory` method. This method uses :func:`os.listdir` to scan the directory, and returns a ``404`` error response if the :func:`listdir` fails. If the request was mapped to a file, it is opened and the contents are returned. Any :exc:`IOError` exception in opening the requested file is mapped to a ``404``, ``'File not found'`` error. Otherwise, the content type is guessed by calling the :meth:`guess_type` method, which in turn uses the *extensions_map* variable. A ``'Content-type:'`` header with the guessed content type is output, followed by a ``'Content-Length:'`` header with the file's size and a ``'Last-Modified:'`` header with the file's modification time. Then follows a blank line signifying the end of the headers, and then the contents of the file are output. If the file's MIME type starts with ``text/`` the file is opened in text mode; otherwise binary mode is used. For example usage, see the implementation of the :func:`test` function. .. versionadded:: 2.5 The ``'Last-Modified'`` header. .. seealso:: Module :mod:`BaseHTTPServer` Base class implementation for Web server and request handler.
