Supports constructing :class:`~urllib3.fields.RequestField` from parameter of key/value strings AND key/filetuple. A filetuple is a (filename, data, MIME type) tuple where the MIME type is optional. For example:: 'foo': 'bar', 'fakefile': ('foofile.txt', 'contents of foofile'), 'realfile': ('barfile.txt', open('realfile').read()), 'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'), 'nonamefile': 'contents of nonamefile field', Field names and filenames must be unicode. � N)r )� content_type)r �tuple�lenr �make_multipart)�clsZ fieldnamer r r r" Z request_paramr r r � from_tuplesG s zRequestField.from_tuplesc C s t ||�S )a Overridable helper function to format a single header parameter. :param name: The name of the parameter, a string expected to be ASCII only. :param value: The value of the parameter, provided as a unicode string. )r )r r r r r r � _render_parti s zRequestField._render_partc C sP g }|}t |t�r|j� }x*|D ]"\}}|dk r |j| j||�� q W dj|�S )aO Helper function to format and quote a single header.
