django的json返回值带有汉字的处理

from django.http import HttpResponse
from django.utils import simplejson
from django.conf import settings

def json(data):
encode = settings.DEFAULT_CHARSET
return HttpResponse(simplejson.dumps(uni_str(data, encode)))

def uni_str(a, encoding):
if isinstance(a, (list, tuple)):
s = []
for i, k in enumerate(a):
s.append(uni_str(k, encoding))
return s
elif isinstance(a, dict):
s = ｛｝
for i, k in enumerate(a.items()):
key, value = k
s[uni_str(key, encoding)] = uni_str(value, encoding)
return s
elif isinstance(a, str) or (hasattr(a, ‘__str__’) and callable(getattr(a, ‘__str__’))):
if getattr(a, ‘__str__’):
a = str(a)
return unicode(a, encoding)
elif isinstance(a, unicode):
return a
else:
return a
