decode_json(obj)#

Custom json decoder for object, in case it is represented as complex number, ndarray or tuple. Otherwise decoder won’t be applied

Here is an example of encoded/decoded json with complex number and ndarray:

>>> import base64
>>> import numpy as np
>>> from exa.common.helpers.json_helper import decode_json
>>> complex_encoded = {'__complex__': True, 'real': 3, 'imag': 4}
>>> decode_json(complex_encoded)
(3+4j)

>>> data_b64 = base64.b64encode(np.arange(4).reshape(2, 2))
>>> ndarray_encoded = {'__ndarray__': True, 'data': data_b64.decode('utf-8'), 'dtype': 'int64', 'shape':[2, 2]}
>>> decode_json(ndarray_encoded)
array([[0, 1],
       [2, 3]])
Parameters:

obj (Any) –

Return type:
