关于python中json load出来编码为unicode的问题的解决

>>> import json
>>> import yaml
>>> list_org = ['a', 'b']>>> list_dump = json.dumps(list_org)>>> list_dump
'["a"
4000
, "b"]'>>> json.loads(list_dump)[u'a', u'b']>>> yaml.safe_load(list_dump)['a', 'b']

import json

def json_load_byteified(file_handle):
return _byteify(
json.load(file_handle, object_hook=_byteify),
ignore_dicts=True
)

def json_loads_byteified(json_text):
return _byteify(
json.loads(json_text, object_hook=_byteify),
ignore_dicts=True
)

def _byteify(data, ignore_dicts = False):
# if this is a unicode string, return its string representation
if isinstance(data, unicode):
return data.encode('utf-8')
# if this is a list of values, return list of byteified values
if isinstance(data, list):
return [ _byteify(item, ignore_dicts=True) for item in data ]
# if this is a dictionary, return dictionary of byteified keys and values
# but only if we haven't already byteified it
if isinstance(data, dict) and not ignore_dicts:
return {
_byteify(key, ignore_dicts=True): _byteify(value, ignore_dicts=True)
for key, value in data.iteritems()
}
# if it's anything else, return it in its original form
return data
