77 Variables
79 • typ (str) -- The unrecognized type of the JSON object.
81 • jobj -- Full JSON object.
83
85 JOSE interfaces.
86 class josepy.interfaces.JSONDeSerializable
88 Interface for (de)serializable JSON objects.
89 Please recall, that standard Python library implements json.JSO‐
91 NEncoder and json.JSONDecoder that perform translations based on
92 respective conversion tables that look pretty much like the one
93 below (for complete tables see relevant Python documentation):
94 ┌───────┬────────┐
96 │JSON │ Python │
97 ├───────┼────────┤
98 │object │ dict │
99 ├───────┼────────┤
100 │... │ ... │
101 └───────┴────────┘
102 While the above conversion table is about translation of JSON
104 documents to/from the basic Python types only,
105 JSONDeSerializable introduces the following two concepts:
106 serialization
108 Turning an arbitrary Python object into Python object
109 that can be encoded into a JSON document. Full serial‐
110 ization produces a Python object composed of only ba‐
111 sic types as required by the conversion table. Partial
112 serialization (accomplished by to_partial_json()) pro‐
113 duces a Python object that might also be built from
114 other JSONDeSerializable objects.
115 deserialization
117 Turning a decoded Python object (necessarily one of
118 the basic types as required by the conversion table)
119 into an arbitrary Python object.
120 Serialization produces serialized object ("partially serialized
122 object" or "fully serialized object" for partial and full seri‐
123 alization respectively) and deserialization produces deserial‐
124 ized object, both usually denoted in the source code as jobj.
125 Wording in the official Python documentation might be confusing
127 after reading the above, but in the light of those definitions,
128 one can view json.JSONDecoder.decode() as decoder and deserial‐
129 izer of basic types, json.JSONEncoder.default() as serializer of
130 basic types, json.JSONEncoder.encode() as serializer and en‐
131 coder of basic types.
132 One could extend json to support arbitrary object (de)serializa‐
134 tion either by:
135 • overriding json.JSONDecoder.decode() and json.JSONEn‐
137 coder.default() in subclasses
138 • or passing object_hook argument (or object_hook_pairs) to
140 json.load()/json.loads() or default argument for
141 json.dump()/json.dumps().
142 Interestingly, default is required to perform only partial seri‐
144 alization, as json.dumps() applies default recursively. This is
145 the idea behind making to_partial_json() produce only partial
146 serialization, while providing custom json_dumps() that dumps
147 with default set to json_dump_default().
148 To make further documentation a bit more concrete, please, con‐
150 sider the following imaginatory implementation example:
151 class Foo(JSONDeSerializable):
153 def to_partial_json(self):
154 return 'foo'
155 @classmethod
157 def from_json(cls, jobj):
158 return Foo()
159 class Bar(JSONDeSerializable):
161 def to_partial_json(self):
162 return [Foo(), Foo()]
163 @classmethod
165 def from_json(cls, jobj):
166 return Bar()
167 abstract to_partial_json()
169 Partially serialize.
170 Following the example, partial serialization means the
172 following:
173 assert isinstance(Bar().to_partial_json()[0], Foo)
175 assert isinstance(Bar().to_partial_json()[1], Foo)
176 # in particular...
178 assert Bar().to_partial_json() != ['foo', 'foo']
179 Raises josepy.errors.SerializationError -- in case of any
181 serialization error.
182 Returns
184 Partially serializable object.
185 to_json()
187 Fully serialize.
188 Again, following the example from before, full serializa‐
190 tion means the following:
191 assert Bar().to_json() == ['foo', 'foo']
193 Raises josepy.errors.SerializationError -- in case of any
195 serialization error.
196 Returns
198 Fully serialized object.
199 abstract classmethod from_json(jobj)
201 Deserialize a decoded JSON document.
202 Parameters
204 jobj -- Python object, composed of only other ba‐
205 sic data types, as decoded from JSON document. Not
206 necessarily dict (as decoded from "JSON object"
207 document).
208 Raises josepy.errors.DeserializationError -- if decoding
210 was unsuccessful, e.g. in case of unparseable X509
211 certificate, or wrong padding in JOSE base64 en‐
212 coded string, etc.
213 classmethod json_loads(json_string)
215 Deserialize from JSON document string.
216 json_dumps(**kwargs)
218 Dump to JSON string using proper serializer.
219 Returns
221 JSON document string.
222 Return type
224 str
225 json_dumps_pretty()
227 Dump the object to pretty JSON document string.
228 Return type
230 str
231 classmethod json_dump_default(python_object)
233 Serialize Python object.
234 This function is meant to be passed as default to
236 json.dump() or json.dumps(). They call default(python_ob‐
237 ject) only for non-basic Python types, so this function
238 necessarily raises TypeError if python_object is not an
239 instance of IJSONSerializable.
240 Please read the class docstring for more information.
242
244 JSON (de)serialization framework.
245 The framework presented here is somewhat based on Go's "json" package
247 (especially the omitempty functionality).
248 class josepy.json_util.Field(json_name, default=None, omitempty=False,
250 decoder=None, encoder=None)
251 JSON object field.
252 Field is meant to be used together with JSONObjectWithFields.
254 encoder (decoder) is a callable that accepts a single parameter,
256 i.e. a value to be encoded (decoded), and returns the serialized
257 (deserialized) value. In case of errors it should raise Serial‐
258 izationError (DeserializationError).
259 Note, that decoder should perform partial serialization only.
261 Variables
263 • json_name (str) -- Name of the field when encoded to
265 JSON.
266 • default -- Default value (used when not present in JSON
268 object).
269 • omitempty (bool) -- If True and the field value is
271 empty, then it will not be included in the serialized
272 JSON object, and default will be used for deserializa‐
273 tion. Otherwise, if False, field is considered as re‐
274 quired, value will always be included in the serialized
275 JSON objected, and it must also be present when deseri‐
276 alizing.
277 omit(value)
279 Omit the value in output?
280 decoder(fdec)
282 Descriptor to change the decoder on JSON object field.
283 encoder(fenc)
285 Descriptor to change the encoder on JSON object field.
286 decode(value)
288 Decode a value, optionally with context JSON object.
289 encode(value)
291 Encode a value, optionally with context JSON object.
292 classmethod default_decoder(value)
294 Default decoder.
295 Recursively deserialize into immutable types (
297 josepy.util.frozendict instead of dict(), tuple() instead
298 of list()).
299 classmethod default_encoder(value)
301 Default (passthrough) encoder.
302 class josepy.json_util.JSONObjectWithFieldsMeta(name, bases, dikt)
304 Metaclass for JSONObjectWithFields and its subclasses.
305 It makes sure that, for any class cls with __metaclass__ set to
307 JSONObjectWithFieldsMeta:
308 1. All fields (attributes of type Field) in the class definition
310 are moved to the cls._fields dictionary, where keys are field
311 attribute names and values are fields themselves.
312 2. cls.__slots__ is extended by all field attribute names (i.e.
314 not Field.json_name). Original cls.__slots__ are stored in
315 cls._orig_slots.
316 In a consequence, for a field attribute name some_field,
318 cls.some_field will be a slot descriptor and not an instance of
319 Field. For example:
320 some_field = Field('someField', default=())
322 class Foo(object):
324 __metaclass__ = JSONObjectWithFieldsMeta
325 __slots__ = ('baz',)
326 some_field = some_field
327 assert Foo.__slots__ == ('some_field', 'baz')
329 assert Foo._orig_slots == ()
330 assert Foo.some_field is not Field
331 assert Foo._fields.keys() == ['some_field']
333 assert Foo._fields['some_field'] is some_field
334 As an implementation note, this metaclass inherits from
336 abc.ABCMeta (and not the usual type) to mitigate the metaclass
337 conflict (ImmutableMap and JSONDeSerializable, parents of
338 JSONObjectWithFields, use abc.ABCMeta as its metaclass).
339 class josepy.json_util.JSONObjectWithFields(**kwargs)
341 JSON object with fields.
342 Example:
344 class Foo(JSONObjectWithFields):
346 bar = Field('Bar')
347 empty = Field('Empty', omitempty=True)
348 @bar.encoder
350 def bar(value):
351 return value + 'bar'
352 @bar.decoder
354 def bar(value):
355 if not value.endswith('bar'):
356 raise errors.DeserializationError('No bar suffix!')
357 return value[:-3]
358 assert Foo(bar='baz').to_partial_json() == {'Bar': 'bazbar'}
360 assert Foo.from_json({'Bar': 'bazbar'}) == Foo(bar='baz')
361 assert (Foo.from_json({'Bar': 'bazbar', 'Empty': '!'})
362 == Foo(bar='baz', empty='!'))
363 assert Foo(bar='baz').bar == 'baz'
364 encode(name)
366 Encode a single field.
367 Parameters
369 name (str) -- Name of the field to be encoded.
370 Raises
372 • errors.SerializationError -- if field cannot be
374 serialized
375 • errors.Error -- if field could not be found
377 fields_to_partial_json()
379 Serialize fields to JSON.
380 to_partial_json()
382 Partially serialize.
383 Following the example, partial serialization means the
385 following:
386 assert isinstance(Bar().to_partial_json()[0], Foo)
388 assert isinstance(Bar().to_partial_json()[1], Foo)
389 # in particular...
391 assert Bar().to_partial_json() != ['foo', 'foo']
392 Raises josepy.errors.SerializationError -- in case of any
394 serialization error.

859 Raises josepy.errors.SerializationError -- in case of any
861 serialization error.
862 Returns
864 Partially serializable object.
865 classmethod from_json(jobj)
867 Deserialize a decoded JSON document.
868 Parameters
870 jobj -- Python object, composed of only other ba‐
871 sic data types, as decoded from JSON document. Not
872 necessarily dict (as decoded from "JSON object"
873 document).
874 Raises josepy.errors.DeserializationError -- if decoding
876 was unsuccessful, e.g. in case of unparseable X509
877 certificate, or wrong padding in JOSE base64 en‐
878 coded string, etc.
879 class josepy.jws.CLI
881 JWS CLI.
882 classmethod sign(args)
884 Sign.

887 Verify.
888 classmethod run(args=None)
890 Parse arguments and sign/verify.
891
893 JOSE utilities.
894 class josepy.util.abstractclassmethod(target)
896 Descriptor for an abstract classmethod.
897 It augments the abc framework with an abstract classmethod. This
899 is implemented as abc.abstractclassmethod in the standard Python
900 library starting with version 3.2.
901 This implementation is from a StackOverflow answer that was de‐
903 rived from the implementation in the Python 3.3 abc library.
