:mod:`http.server` --- HTTP servers =================================== .. module:: http.server :synopsis: HTTP server and request handlers. **Source code:** :source:`Lib/http/server.py` .. index:: pair: WWW; server pair: HTTP; protocol single: URL single: httpd -------------- This module defines classes for implementing HTTP servers (Web servers). One class, :class:`HTTPServer`, is a :class:`socketserver.TCPServer` subclass. It creates and listens at the HTTP socket, dispatching the requests to a handler. Code to create and run the server looks like this:: def run(server_class=HTTPServer, handler_class=BaseHTTPRequestHandler): server_address = ('', 8000) httpd = server_class(server_address, handler_class) httpd.serve_forever() .. class:: HTTPServer(server_address, RequestHandlerClass) This class builds on the :class:`~socketserver.TCPServer` class by storing the server address as instance variables named :attr:`server_name` and :attr:`server_port`. The server is accessible by the handler, typically through the handler's :attr:`server` instance variable. The :class:`HTTPServer` must be given a *RequestHandlerClass* on instantiation, of which this module provides three different variants: .. class:: BaseHTTPRequestHandler(request, client_address, server) This class is used to handle the HTTP requests that arrive at the server. By itself, it cannot respond to any actual HTTP requests; it must be subclassed to handle each request method (e.g. GET or POST). :class:`BaseHTTPRequestHandler` provides a number of class and instance variables, and methods for use by subclasses. The handler will parse the request and the headers, then call a method specific to the request type. The method name is constructed from the request. For example, for the request method ``SPAM``, the :meth:`do_SPAM` method will be called with no arguments. All of the relevant information is stored in instance variables of the handler. Subclasses should not need to override or extend the :meth:`__init__` method. :class:`BaseHTTPRequestHandler` has the following instance variables: .. attribute:: client_address Contains a tuple of the form ``(host, port)`` referring to the client's address. .. attribute:: server Contains the server instance. .. attribute:: close_connection Boolean that should be set before :meth:`handle_one_request` returns, indicating if another request may be expected, or if the connection should be shut down. .. attribute:: requestline Contains the string representation of the HTTP request line. The terminating CRLF is stripped. This attribute should be set by :meth:`handle_one_request`. If no valid request line was processed, it should be set to the empty string. .. attribute:: command Contains the command (request type). For example, ``'GET'``. .. attribute:: path Contains the request path. .. attribute:: request_version Contains the version string from the request. For example, ``'HTTP/1.0'``. .. attribute:: headers Holds an instance of the class specified by the :attr:`MessageClass` class variable. This instance parses and manages the headers in the HTTP request. The :func:`~http.client.parse_headers` function from :mod:`http.client` is used to parse the headers and it requires that the HTTP request provide a valid :rfc:`2822` style header. .. attribute:: rfile An :class:`io.BufferedIOBase` input stream, ready to read from the start of the optional input data. .. attribute:: wfile Contains the output stream for writing a response back to the client. Proper adherence to the HTTP protocol must be used when writing to this stream in order to achieve successful interoperation with HTTP clients. .. versionchanged:: 3.6 This is an :class:`io.BufferedIOBase` stream. :class:`BaseHTTPRequestHandler` has the following attributes: .. attribute:: server_version Specifies the server software version. You may want to override this. The format is multiple whitespace-separated strings, where each string is of the form name[/version]. For example, ``'BaseHTTP/0.2'``. .. attribute:: sys_version Contains the Python system version, in a form usable by the :attr:`version_string` method and the :attr:`server_version` class variable. For example, ``'Python/1.4'``. .. attribute:: error_message_format Specifies a format string that should be used by :meth:`send_error` method for building an error response to the client. The string is filled by default with variables from :attr:`responses` based on the status code that passed to :meth:`send_error`. .. attribute:: error_content_type Specifies the Content-Type HTTP header of error responses sent to the client. The default value is ``'text/html'``. .. attribute:: protocol_version This specifies the HTTP protocol version used in responses. If set to ``'HTTP/1.1'``, the server will permit HTTP persistent connections; however, your server *must* then include an accurate ``Content-Length`` header (using :meth:`send_header`) in all of its responses to clients. For backwards compatibility, the setting defaults to ``'HTTP/1.0'``. .. attribute:: MessageClass Specifies an :class:`email.message.Message`\ -like class to parse HTTP headers. Typically, this is not overridden, and it defaults to :class:`http.client.HTTPMessage`. .. attribute:: responses This attribute contains a mapping of error code integers to two-element tuples containing a short and long message. For example, ``{code: (shortmessage, longmessage)}``. The *shortmessage* is usually used as the *message* key in an error response, and *longmessage* as the *explain* key. It is used by :meth:`send_response_only` and :meth:`send_error` methods. A :class:`BaseHTTPRequestHandler` instance has the following methods: .. method:: handle() Calls :meth:`handle_one_request` once (or, if persistent connections are enabled, multiple times) to handle incoming HTTP requests. You should never need to override it; instead, implement appropriate :meth:`do_\*` methods. .. method:: handle_one_request() This method will parse and dispatch the request to the appropriate :meth:`do_\*` method. You should never need to override it. .. method:: handle_expect_100() When a HTTP/1.1 compliant server receives an ``Expect: 100-continue`` request header it responds back with a ``100 Continue`` followed by ``200 OK`` headers. This method can be overridden to raise an error if the server does not want the client to continue. For e.g. server can chose to send ``417 Expectation Failed`` as a response header and ``return False``. .. versionadded:: 3.2 .. method:: send_error(code, message=None, explain=None) Sends and logs a complete error reply to the client. The numeric *code* specifies the HTTP error code, with *message* as an optional, short, human readable description of the error. The *explain* argument can be used to provide more detailed information about the error; it will be formatted using the :attr:`error_message_format` attribute and emitted, after a complete set of headers, as the response body. The :attr:`responses` attribute holds the default values for *message* and *explain* that will be used if no value is provided; for unknown codes the default value for both is the string ``???``. The body will be empty if the method is HEAD or the response code is one of the following: ``1xx``, ``204 No Content``, ``205 Reset Content``, ``304 Not Modified``. .. versionchanged:: 3.4 The error response includes a Content-Length header. Added the *explain* argument. .. method:: send_response(code, message=None) Adds a response header to the headers buffer and logs the accepted request. The HTTP response line is written to the internal buffer, followed by *Server* and *Date* headers. The values for these two headers are picked up from the :meth:`version_string` and :meth:`date_time_string` methods, respectively. If the server does not intend to send any other headers using the :meth:`send_header` method, then :meth:`send_response` should be followed by an :meth:`end_headers` call. .. versionchanged:: 3.3 Headers are stored to an internal buffer and :meth:`end_headers` needs to be called explicitly. .. method:: send_header(keyword, value) Adds the HTTP header to an internal buffer which will be written to the output stream when either :meth:`end_headers` or :meth:`flush_headers` is invoked. *keyword* should specify the header keyword, with *value* specifying its value. Note that, after the send_header calls are done, :meth:`end_headers` MUST BE called in order to complete the operation. .. versionchanged:: 3.2 Headers are stored in an internal buffer. .. method:: send_response_only(code, message=None) Sends the response header only, used for the purposes when ``100 Continue`` response is sent by the server to the client. The headers not buffered and sent directly the output stream.If the *message* is not specified, the HTTP message corresponding the response *code* is sent. .. versionadded:: 3.2 .. method:: end_headers() Adds a blank line (indicating the end of the HTTP headers in the response) to the headers buffer and calls :meth:`flush_headers()`. .. versionchanged:: 3.2 The buffered headers are written to the output stream. .. method:: flush_headers() Finally send the headers to the output stream and flush the internal headers buffer. .. versionadded:: 3.3 .. method:: log_request(code='-', size='-') Logs an accepted (successful) request. *code* should specify the numeric HTTP code associated with the response. If a size of the response is available, then it should be passed as the *size* parameter. .. method:: log_error(...) Logs an error when a request cannot be fulfilled. By default, it passes the message to :meth:`log_message`, so it takes the same arguments (*format* and additional values). .. method:: log_message(format, ...) Logs an arbitrary message to ``sys.stderr``. This is typically overridden to create custom error logging mechanisms. The *format* argument is a standard printf-style format string, where the additional arguments to :meth:`log_message` are applied as inputs to the formatting. The client ip address and current date and time are prefixed to every message logged. .. method:: version_string() Returns the server software's version string. This is a combination of the :attr:`server_version` and :attr:`sys_version` attributes. .. method:: date_time_string(timestamp=None) Returns the date and time given by *timestamp* (which must be ``None`` or in the format returned by :func:`time.time`), formatted for a message header. If *timestamp* is omitted, it uses the current date and time. The result looks like ``'Sun, 06 Nov 1994 08:49:37 GMT'``. .. method:: log_date_time_string() Returns the current date and time, formatted for logging. .. method:: address_string() Returns the client address. .. versionchanged:: 3.3 Previously, a name lookup was performed. To avoid name resolution delays, it now always returns the IP address. .. 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:`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:`~os.listdir` fails. If the request was mapped to a file, it is opened and the contents are returned. Any :exc:`OSError` 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 invocation in the :mod:`http.server` module. The :class:`SimpleHTTPRequestHandler` class can be used in the following manner in order to create a very basic webserver serving files relative to the current directory:: import http.server import socketserver PORT = 8000 Handler = http.server.SimpleHTTPRequestHandler with socketserver.TCPServer(("", PORT), Handler) as httpd: print("serving at port", PORT) httpd.serve_forever() .. _http-server-cli: :mod:`http.server` can also be invoked directly using the :option:`-m` switch of the interpreter with a ``port number`` argument. Similar to the previous example, this serves files relative to the current directory:: python -m http.server 8000 By default, server binds itself to all interfaces. The option ``-b/--bind`` specifies a specific address to which it should bind. For example, the following command causes the server to bind to localhost only:: python -m http.server 8000 --bind 127.0.0.1 .. versionadded:: 3.4 ``--bind`` argument was introduced. .. 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:`SimpleHTTPRequestHandler`. .. 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 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 method: .. 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. :class:`CGIHTTPRequestHandler` can be enabled in the command line by passing the ``--cgi`` option:: python -m http.server --cgi 8000
