| :mod:`httplib` --- HTTP protocol client |
| ======================================= |
| |
| .. module:: httplib |
| :synopsis: HTTP and HTTPS protocol client (requires sockets). |
| |
| |
| .. index:: |
| pair: HTTP; protocol |
| single: HTTP; httplib (standard module) |
| |
| .. index:: module: urllib |
| |
| This module defines classes which implement the client side of the HTTP and |
| HTTPS protocols. It is normally not used directly --- the module :mod:`urllib` |
| uses it to handle URLs that use HTTP and HTTPS. |
| |
| .. note:: |
| |
| HTTPS support is only available if the :mod:`socket` module was compiled with |
| SSL support. |
| |
| The module provides the following classes: |
| |
| |
| .. class:: HTTPConnection(host[, port[, strict[, timeout]]]) |
| |
| An :class:`HTTPConnection` instance represents one transaction with an HTTP |
| server. It should be instantiated passing it a host and optional port number. |
| If no port number is passed, the port is extracted from the host string if it |
| has the form ``host:port``, else the default HTTP port (80) is used. When True, |
| the optional parameter *strict* causes ``BadStatusLine`` to be raised if the |
| status line can't be parsed as a valid HTTP/1.0 or 1.1 status line. If the |
| optional *timeout* parameter is given, connection attempts will timeout after |
| that many seconds (if it is not given or ``None``, the global default timeout |
| setting is used). |
| |
| For example, the following calls all create instances that connect to the server |
| at the same host and port:: |
| |
| >>> h1 = httplib.HTTPConnection('www.cwi.nl') |
| >>> h2 = httplib.HTTPConnection('www.cwi.nl:80') |
| >>> h3 = httplib.HTTPConnection('www.cwi.nl', 80) |
| >>> h3 = httplib.HTTPConnection('www.cwi.nl', 80, timeout=10) |
| |
| |
| .. class:: HTTPSConnection(host[, port[, key_file[, cert_file[, strict[, timeout]]]]]) |
| |
| A subclass of :class:`HTTPConnection` that uses SSL for communication with |
| secure servers. Default port is ``443``. *key_file* is the name of a PEM |
| formatted file that contains your private key. *cert_file* is a PEM formatted |
| certificate chain file. |
| |
| .. warning:: |
| |
| This does not do any certificate verification! |
| |
| |
| .. class:: HTTPResponse(sock[, debuglevel=0][, strict=0]) |
| |
| Class whose instances are returned upon successful connection. Not instantiated |
| directly by user. |
| |
| |
| The following exceptions are raised as appropriate: |
| |
| |
| .. exception:: HTTPException |
| |
| The base class of the other exceptions in this module. It is a subclass of |
| :exc:`Exception`. |
| |
| |
| .. exception:: NotConnected |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: InvalidURL |
| |
| A subclass of :exc:`HTTPException`, raised if a port is given and is either |
| non-numeric or empty. |
| |
| |
| .. exception:: UnknownProtocol |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: UnknownTransferEncoding |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: UnimplementedFileMode |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: IncompleteRead |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: ImproperConnectionState |
| |
| A subclass of :exc:`HTTPException`. |
| |
| |
| .. exception:: CannotSendRequest |
| |
| A subclass of :exc:`ImproperConnectionState`. |
| |
| |
| .. exception:: CannotSendHeader |
| |
| A subclass of :exc:`ImproperConnectionState`. |
| |
| |
| .. exception:: ResponseNotReady |
| |
| A subclass of :exc:`ImproperConnectionState`. |
| |
| |
| .. exception:: BadStatusLine |
| |
| A subclass of :exc:`HTTPException`. Raised if a server responds with a HTTP |
| status code that we don't understand. |
| |
| The constants defined in this module are: |
| |
| |
| .. data:: HTTP_PORT |
| |
| The default port for the HTTP protocol (always ``80``). |
| |
| |
| .. data:: HTTPS_PORT |
| |
| The default port for the HTTPS protocol (always ``443``). |
| |
| and also the following constants for integer status codes: |

| .. data:: responses |
| |
| This dictionary maps the HTTP 1.1 status codes to the W3C names. |
| |
| Example: ``httplib.responses[httplib.NOT_FOUND]`` is ``'Not Found'``. |
| |
| |
| .. _httpconnection-objects: |
| |
| HTTPConnection Objects |
| ---------------------- |
| |
| :class:`HTTPConnection` instances have the following methods: |
| |
| |
| .. method:: HTTPConnection.request(method, url[, body[, headers]]) |
| |
| This will send a request to the server using the HTTP request method *method* |
| and the selector *url*. If the *body* argument is present, it should be a |
| string of data to send after the headers are finished. Alternatively, it may |
| be an open file object, in which case the contents of the file is sent; this |
| file object should support ``fileno()`` and ``read()`` methods. The header |
| Content-Length is automatically set to the correct value. The *headers* |
| argument should be a mapping of extra HTTP headers to send with the request. |
| |
| |
| .. method:: HTTPConnection.getresponse() |
| |
| Should be called after a request is sent to get the response from the server. |
| Returns an :class:`HTTPResponse` instance. |
| |
| .. note:: |
| |
| Note that you must have read the whole response before you can send a new |
| request to the server. |
| |
| |
| .. method:: HTTPConnection.set_debuglevel(level) |
| |
| Set the debugging level (the amount of debugging output printed). The default |
| debug level is ``0``, meaning no debugging output is printed. |
| |
| |
| .. method:: HTTPConnection.connect() |
| |
| Connect to the server specified when the object was created. |
| |
| |
| .. method:: HTTPConnection.close() |
| |
| Close the connection to the server. |
| |
| As an alternative to using the :meth:`request` method described above, you can |
| also send your request step by step, by using the four functions below. |
| |
| |
| .. method:: HTTPConnection.putrequest(request, selector[, skip_host[, skip_accept_encoding]]) |
| |
| This should be the first call after the connection to the server has been made. |
| It sends a line to the server consisting of the *request* string, the *selector* |
| string, and the HTTP version (``HTTP/1.1``). To disable automatic sending of |
| ``Host:`` or ``Accept-Encoding:`` headers (for example to accept additional |
| content encodings), specify *skip_host* or *skip_accept_encoding* with non-False |
| values. |
| |
| |
| .. method:: HTTPConnection.putheader(header, argument[, ...]) |
| |
| Send an :rfc:`822`\ -style header to the server. It sends a line to the server |
| consisting of the header, a colon and a space, and the first argument. If more |
| arguments are given, continuation lines are sent, each consisting of a tab and |
| an argument. |
| |
| |
| .. method:: HTTPConnection.endheaders() |
| |
| Send a blank line to the server, signalling the end of the headers. |
| |
| |
| .. method:: HTTPConnection.send(data) |
| |
| Send data to the server. This should be used directly only after the |
| :meth:`endheaders` method has been called and before :meth:`getresponse` is |
| called. |
| |
| |
| .. _httpresponse-objects: |
| |
| HTTPResponse Objects |
| -------------------- |
| |
| :class:`HTTPResponse` instances have the following methods and attributes: |
| |
| |
| .. method:: HTTPResponse.read([amt]) |
| |
| Reads and returns the response body, or up to the next *amt* bytes. |
| |
| |
| .. method:: HTTPResponse.getheader(name[, default]) |
| |
| Get the contents of the header *name*, or *default* if there is no matching |
| header. |
| |
| |
| .. method:: HTTPResponse.getheaders() |
| |
| Return a list of (header, value) tuples. |
| |
| |
| .. attribute:: HTTPResponse.msg |
| |
| A :class:`mimetools.Message` instance containing the response headers. |
| |
| |
| .. attribute:: HTTPResponse.version |
| |
| HTTP protocol version used by server. 10 for HTTP/1.0, 11 for HTTP/1.1. |
| |
| |
| .. attribute:: HTTPResponse.status |
| |
| Status code returned by server. |
| |
| |
| .. attribute:: HTTPResponse.reason |
| |
| Reason phrase returned by server. |
| |

| Here is an example session that shows how to ``POST`` requests:: |
| |
| >>> import httplib, urllib |
| >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) |
| >>> headers = {"Content-type": "application/x-www-form-urlencoded", |
| ... "Accept": "text/plain"} |
| >>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80") |
| >>> conn.request("POST", "/cgi-bin/query", params, headers) |
| >>> response = conn.getresponse() |
| >>> print(response.status, response.reason) |
| 200 OK |
| >>> data = response.read() |
| >>> conn.close() |
