Supports the following objects and types by default: +-------------------+---------------+ | Python | JSON | +===================+===============+ | dict, namedtuple | object | +-------------------+---------------+ | list, tuple | array | +-------------------+---------------+ | str, unicode | string | +-------------------+---------------+ | int, long, float | number | +-------------------+---------------+ | True | true | +-------------------+---------------+ | False | false | +-------------------+---------------+ | None | null | +-------------------+---------------+ To extend this to recognize other objects, subclass and implement a ``.default()`` method with another method that returns a serializable object for ``o`` if possible, otherwise it should call the superclass implementation (to raise ``TypeError``). z, z: FTNr c C s� || _ || _|| _|| _|| _| | _| | _| | _|| _| | _ || _ || _ || _ || _ |dk rnt|t�sn|d }|| _|dk r�|\| _| _n|dk r�d| _| dk r�| | _|| _dS )a� Constructor for JSONEncoder, with sensible defaults. If skipkeys is false, then it is a TypeError to attempt encoding of keys that are not str, int, long, float or None. If skipkeys is True, such items are simply skipped. If ensure_ascii is true, the output is guaranteed to be str objects with all incoming unicode characters escaped. If ensure_ascii is false, the output will be unicode object. If check_circular is true, then lists, dicts, and custom encoded objects will be checked for circular references during encoding to prevent an infinite recursion (which would cause an OverflowError). Otherwise, no such check takes place. If allow_nan is true, then NaN, Infinity, and -Infinity will be encoded as such. This behavior is not JSON specification compliant, but is consistent with most JavaScript based encoders and decoders. Otherwise, it will be a ValueError to encode such floats. If sort_keys is true, then the output of dictionaries will be sorted by key; this is useful for regression tests to ensure that JSON serializations can be compared on a day-to-day basis. If indent is a string, then JSON array elements and object members will be pretty-printed with a newline followed by that string repeated for each level of nesting. ``None`` (the default) selects the most compact representation without any newlines. For backwards compatibility with versions of simplejson earlier than 2.1.0, an integer is also accepted and is converted to a string with that many spaces. If specified, separators should be an (item_separator, key_separator) tuple. The default is (', ', ': ') if *indent* is ``None`` and (',', ': ') otherwise. To get the most compact JSON representation, you should specify (',', ':') to eliminate whitespace. If specified, default is a function that gets called for objects that can't otherwise be serialized. It should return a JSON encodable version of the object or raise a ``TypeError``. If encoding is not None, then all input strings will be transformed into unicode using that encoding prior to JSON-encoding. The default is UTF-8. If use_decimal is true (default: ``True``), ``decimal.Decimal`` will be supported directly by the encoder. For the inverse, decode JSON with ``parse_float=decimal.Decimal``. If namedtuple_as_object is true (the default), objects with ``_asdict()`` methods will be encoded as JSON objects. If tuple_as_array is true (the default), tuple (and subclasses) will be encoded as JSON arrays. If *iterable_as_array* is true (default: ``False``), any object not in the above table that implements ``__iter__()`` will be encoded as a JSON array. If bigint_as_string is true (not the default), ints 2**53 and higher or lower than -2**53 will be encoded as strings. This is to avoid the rounding that happens in Javascript otherwise. If int_as_string_bitcount is a positive number (n), then int of size greater than or equal to 2**n or lower than or equal to -2**n will be encoded as strings. If specified, item_sort_key is a callable used to sort the items in each dictionary. This is useful if you want to sort items other than in alphabetical order by key. If for_json is true (not the default), objects with a ``for_json()`` method will use the return value of that method for encoding as JSON instead of the object. If *ignore_nan* is true (default: ``False``), then out of range :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as ``null`` in compliance with the ECMA-262 specification. If true, this will override *allow_nan*.

To embed JSON content in, say, a script tag on a web page, the characters &, < and > should be escaped. They cannot be escaped with the usual entities (e.g. &) because they are not expanded within <script> tags. This class also escapes the line separator and paragraph separator characters U+2028 and U+2029, irrespective of the ensure_ascii setting, as these characters are not valid in JavaScript strings (see http://timelessrepo.com/json-isnt-a-javascript-subset). c C s* | � |d�}| jr d�|�S d�|�S d S )NTr )rV r= rY )rO rT r[ r r r r\ � s zJSONEncoderForHTML.encodeFc # sh t t| ��||�}|D ]L}|�dd�}|�dd�}|�dd�}| js\|�dd�}|�d d �}|V qd S ) N�&z\u0026�<z\u003c�>z\u003eu z\u2028u z\u2029)�superrp rV r" r= )rO rT rU r[ �chunk�rR r r rV � s z JSONEncoderForHTML.iterencode)F)rS rm rn ro r\ rV � __classcell__r r rv r rp s rp c sP �r� d krt j� � r(t� �s(td��n|r8� s8td�� � d k rZ� dksR�� ��sZtd��� �� fdd��� �������� � ������������ � � � �!fdd��� ��������� � f dd ��� �������� � � �������������� � � � �!f d d ��� ��������� ������������ � � � � �!fd d ���S )Nz&item_sort_key must be None or callabler z1int_as_string_bitcount must be a positive integerc s` � d kp� dk }t | ��kr$t| �} |sHd� > | k rDd� > k rPn n�| �S d�| � d S )Nr ���r )r& �int)�valueZ skip_quoting)�_int_as_string_bitcountr r% r r � _encode_int� s � ��� z%_make_iterencode.<locals>._encode_intc 3 s� | sdV d S �d k r6�| �}|�kr.�d��| �|< d}�d k rh|d7 }d�| }� | }||7 }nd }� }d}| D �]�}|r�d}n|}�|��r�|�|� V qx�r̈|t �r̈d k r�|�|� V qx�|t�r�||j V qx|d k� r�|d V qx|dk�r|d V qx|dk�r&|d V qx�|���rB|�|� V qx�|���r^|�|� V qx��r��|� ��r�|�|� V qx|V ��o�t|d d �}|�r�t|��r�� |� |�} n��|���rΈ ||�} np� �o�t|d d �} | �r�t| ��r�� | � |�} n@��r �|���r � ||�} n"�|���r4� ||�} n � ||�} | D ] } | V �qBqx|�r`dV n&|d k �r�|d8 }d�| V d V �d k �r��|= d S )Nz[]�Circular reference detected�[r r TFr^ �true�falserG �_asdict�])r$ r � encoded_json�getattr�callable) Zlst�_current_indent_level�markeridZbuf�newline_indentZ separator�firstrz rG r[ r� ru )re r` r/ r| r] rZ � _floatstr� _for_json�_indent�_item_separatorrl �_iterencode_dict�_iterencode_list�_namedtuple_as_object�_tuple_as_array� _use_decimal�dictr_ �idr r# rW rk r% r rX r r r� � s� � z*_make_iterencode.<locals>._iterencode_listc s� �| � �r n��r.�| t �r.�d k r.� | ��} n��| ��rB�| �} n�| dkrPd} nv| dkr^d} nh| d krld} nZ�| ��r�t| ��kr�t| �} � | �} n2�r��| � �r�� | �} n�r�d } ntd| jj ��| S )NTr Fr� r^ z2keys must be str, int, float, bool or None, not %s)r$ r& ry rQ rR rS ��key) re r/ rZ r� � _skipkeysr� r_ r r# r% r r r �_stringify_key s0 �z(_make_iterencode.<locals>._stringify_keyc 3 s | sdV d S �d k r6�| �}|�kr.�d��| �|< dV �d k rh|d7 }d�| }� | }|V nd }� }d}�r�| � � }n| �� }� r�g }| � � D ]2\}} �|��s��|�}|d kr�q�|�|| f� q�|j� d� n|}|D �]�\} } � �s�| ���s�| �} | d k�rq�|�r d}n|V �| �V �V �| ���rN�| �V q��rv�| t��rv�d k �rv�| �V q�| t��r�| jV q�| d k�r�d V q�| dk�r�d V q�| dk�r�d V q�| ���rڈ| �V q�| ���r�| �V q��r�| � ��r�| �V q��o t| d d �} | �r@t| ��r@� | � |�} n��| ���rX� | |�} np��oht| d d �}|�r�t|��r�� |� |�} n@��r��| � ��r�� | |�} n"�| ���r�� | |�} n � | |�} | D ] }|V �q�q�|d k �r�|d8 }d�| V dV �d k �r�|= d S )Nz{}r} �{r r Tr� Fr^ r r� rG r� �}) �items� iteritems�append�sortr$ r r� r� r� )Zdctr� r� r� rK r� r� r� �k�vr� rz rG r[ r� ru ) re r` r/ r| r] rZ r� r� r� r� �_item_sort_keyrl r� r� �_key_separatorr� r� r� r� r� r_ r� r r# rW rk r% r rX r r r� ; s� � z*_make_iterencode.<locals>._iterencode_dictc 3 st �| ��r�| �V �nX�r<�| t �r<�d k r<�| �V �n4�| t�rR| jV �n | d krddV �n | dkrvdV �n�| dkr�dV �n�| ��r��| �V �nЈ| ��r��| �V �n��o�t| dd �}|r�t|�r� |� |�D ] }|V q�n��| ���r� | |�D ] }|V �q�nX� �o(t| dd �}|�rXt|��rX� |� |�D ] }|V �qF�n��r��| ���r�� | |�D ] }|V �qtn�| ���r�� | |�D ] }|V �q�nƈ�rȈ| � ��rȈ| �V n�� �rz �| �} W n tk �r� Y �qY nX � | |�D ] }|V �qd S �d k �r@�| �}|�k�r8�d��| �|< �| �} � | |�D ] }|V �qR�d k �rp�|= d S ) Nr^ Tr Fr� rG r� r} )r$ r r� r� r� rQ )rT r� rG ru r� r� )re r` r/ �_defaultr| r] rZ r� r� �_iterable_as_arrayrl r� r� r� r� r� r� r_ r� r r# �iterrW rk r% r rX r r rl � sn � z%_make_iterencode.<locals>._iterencode)rh re r� rQ r ) rk r� r] r� r� r� r� Z _sort_keysr� rU r� r� r� r{ r� rZ r� r� r/ r` r re r� r_ r� r r# rW r% rX r� r )"re r` r/ r� r| r] rZ r� r� r� r{ r� r� r� rl r� r� r� r� r� r� r� r� r� r_ r� r r# r� rW rk r% r rX r ri � s$ ��>I DZ@=ri )0ro Z __future__r �re�operatorr rh �compatr r r r r r r Zc_encode_basestring_asciirg �decoderr Zraw_jsonr �compiler, r7 r( r �range�i� setdefault�chrra rf r0 r8 r �objectr9 rp r` r� r_ r� r# rW r% rX r� ri r r r r �<module> sZ � *� ,�
