Convert a nested data structure to a json string.

|
|
:param obj: The Python object to convert.
|
|
:param sort_keys: Keep this False if you want order to be preserved.
|
|
:param cls: The json encoder class to use, defaults to NoNumpyEncoder which gives a warning for numpy arrays.
|
|
:param obj_encoders: Iterable of encoders to use to convert arbitrary objects into json-able promitives.
|
|
:param extra_obj_encoders: Like `obj_encoders` but on top of them: use this to add encoders without replacing defaults. Since v3.5 these happen before default encoders.
|
|
:param allow_nan: Allow NaN and Infinity values, which is a (useful) violation of the JSON standard (default False).
|
|
:param conv_str_byte: Try to automatically convert between strings and bytes (assuming utf-8) (default False).
|
|
:return: The string containing the json-encoded version of obj.
|

Other arguments are passed on to `cls`. Note that `sort_keys` should be false if you want to preserve order.
