def tornado.httputil._get_content_range (   start,
  end,
  total 
) [private]
Returns a suitable Content-Range header:

>>> print(_get_content_range(None, 1, 4))
bytes 0-0/4
>>> print(_get_content_range(1, 3, 4))
bytes 1-2/4
>>> print(_get_content_range(None, None, 4))
bytes 0-3/4

def tornado.httputil._int_or_none (   val) [private]

Definition at line 655 of file httputil.py.

def tornado.httputil._parse_header (   line) [private]
Parse a Content-type like header.

Return the main content-type and a dictionary of options.

Definition at line 821 of file httputil.py.

def tornado.httputil._parse_request_range (   range_header) [private]
Parses a Range header.

Returns either ``None`` or tuple ``(start, end)``.
Note that while the HTTP headers use inclusive byte positions,
this method returns indexes suitable for use in slices.

>>> start, end = _parse_request_range("bytes=1-2")
>>> start, end
(1, 3)
>>> [0, 1, 2, 3, 4][start:end]
[1, 2]
>>> _parse_request_range("bytes=6-")
(6, None)
>>> _parse_request_range("bytes=-6")
(-6, None)
>>> _parse_request_range("bytes=-0")
(None, 0)
>>> _parse_request_range("bytes=")
(None, None)
>>> _parse_request_range("foo=42")
>>> _parse_request_range("bytes=1-2,6-10")

Note: only supports one range (ex, ``bytes=1-2,6-10`` is not allowed).

See [0] for the details of the range header.

def tornado.httputil._parseparam (   s) [private]

Definition at line 808 of file httputil.py.

Definition at line 842 of file httputil.py.

Formats a timestamp in the format used by HTTP.

The argument may be a numeric timestamp as returned by `time.time`,
a time tuple as returned by `time.gmtime`, or a `datetime.datetime`
object.

>>> format_timestamp(1359312200)
'Sun, 27 Jan 2013 18:43:20 GMT'

Definition at line 741 of file httputil.py.

def tornado.httputil.parse_body_arguments (   content_type,
  body,
  arguments,
  files,
  headers = None 
)
Parses a form request body.

Supports ``application/x-www-form-urlencoded`` and
``multipart/form-data``.  The ``content_type`` parameter should be
a string and ``body`` should be a byte string.  The ``arguments``
and ``files`` parameters are dictionaries that will be updated
with the parsed contents.

Definition at line 662 of file httputil.py.

def tornado.httputil.parse_multipart_form_data (   boundary,
  data,
  arguments,
  files 
)
Parses a ``multipart/form-data`` body.

The ``boundary`` and ``data`` parameters are both byte strings.
The dictionaries given in the arguments and files parameters
will be updated with the contents of the body.

Definition at line 695 of file httputil.py.

Returns a (method, path, version) tuple for an HTTP 1.x request line.

The response is a `collections.namedtuple`.

>>> parse_request_start_line("GET /foo HTTP/1.1")
RequestStartLine(method='GET', path='/foo', version='HTTP/1.1')

Definition at line 766 of file httputil.py.

Returns a (version, code, reason) tuple for an HTTP 1.x response line.

The response is a `collections.namedtuple`.

>>> parse_response_start_line("HTTP/1.1 200 OK")
ResponseStartLine(version='HTTP/1.1', code=200, reason='OK')

Definition at line 788 of file httputil.py.

def tornado.httputil.url_concat (   url,
  args 
)
Concatenate url and argument dictionary regardless of whether
url has existing query parameters.

>>> url_concat("http://example.com/foo?a=b", dict(c="d"))
'http://example.com/foo?a=b&c=d'
