Helper function to format and quote a single header parameter using the strategy defined in RFC 2231. Particularly useful for header parameters which might contain non-ASCII values, like file names. This follows `RFC 2388 Section 4.4 <https://tools.ietf.org/html/rfc2388#section-4.4>`_. :param name: The name of the parameter, a string expected to be ASCII only. :param value: The value of the parameter, provided as ``bytes`` or `str``. :ret: An RFC-2231-formatted unicode string. �utf-8c 3 s | ]}|� kV qd S �Nr )�.0�ch��valuer r � <genexpr>+ s z.format_header_param_rfc2231.<locals>.<genexpr>z"\ �%s="%s"�asciiz%s*=%s) � isinstancer � binary_type�decode�any�encode�UnicodeEncodeError�UnicodeDecodeError�PY2�email�utils�encode_rfc2231)�namer �resultr r r �format_header_param_rfc2231 s r# z%22z\\)�"�\c C s& i | ] }|d krt �|�d�|��qS ))� z%{:02X})r �unichr�format)r �ccr r r � <dictcomp>J s � r* � c s: � fdd�}t �d�dd� � �� D ���}|�|| �}|S )Nc s � | � d� S )Nr )�group)�match��needles_and_replacementsr r �replacerS s z#_replace_multiple.<locals>.replacer�|c S s g | ]}t �|��qS r )�re�escape)r �needler r r � <listcomp>W s z%_replace_multiple.<locals>.<listcomp>)r2 �compile�join�keys�sub)r r/ r0 �patternr" r r. r �_replace_multipleR s � r; c C s, t |tj�r|�d�}t|t�}d| |f S )a� Helper function to format and quote a single header parameter using the HTML5 strategy. Particularly useful for header parameters which might contain non-ASCII values, like file names. This follows the `HTML5 Working Draft Section 4.10.22.7`_ and matches the behavior of curl and modern browsers. .. _HTML5 Working Draft Section 4.10.22.7: https://w3c.github.io/html/sec-forms.html#multipart-form-data :param name: The name of the parameter, a string expected to be ASCII only. :param value: The value of the parameter, provided as ``bytes`` or `str``. :ret: A unicode string, stripped of troublesome characters. r r )r r r r r; �_HTML5_REPLACEMENTS)r! r r r r �format_header_param_html5_ s r= c @ sR e Zd ZdZddefdd�Zeefdd��Zdd� Zd d � Z d d � Z dd d�Z dS )� RequestFielda A data container for request body parameters. :param name: The name of this request field.

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 rD )� content_type)r �tuple�lenr �make_multipart)�cls� fieldnamer rD r rA rH � request_paramr r r � from_tuples� s � zRequestField.from_tuplesc C s | � ||�S )aI Overridable helper function to format a single header parameter.
