python - 解码编码为GB2312的json

Question

通过 GET 请求，我从 Google geocode API 中提取 json:

import urllib, urllib2

url = "http://maps.googleapis.com/maps/api/geocode/json"
params = {'address': 'ivory coast', 'sensor': 'false'}
request = urllib2.Request(url + "?" + urllib.urlencode(params))
response = urllib2.urlopen(request)
st = response.read()

结果看起来像:

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Côte d'Ivoire",
               "short_name" : "CI",
               "types" : [ "country", "political" ]
            }
         ],
         "formatted_address" : "Côte d'Ivoire",
         "geometry" : { ... # rest snipped

如您所见，国家名称存在一些编码问题。我试着猜测这样的编码:

import chardet
encoding = chardet.detect(st)
print "String is encoded in {0} (with {1}% confidence).".format(encoding['encoding'], encoding['confidence']*100)

哪个返回:

String is encoded in GB2312 (with 99.0% confidence).

我想知道的是如何将其转换为具有正确显示 ô(o with circumflex)编码的字典。

我试过:

st = st.decode(encoding['encoding']).encode('utf-8')

但后来我得到:

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "C么te d'Ivoire",
               "short_name" : "CI",
               "types" : [ "country", "political" ]
            }
         ],
         "formatted_address" : "C么te d'Ivoire",
         "geometry" : { ... # rest snipped

google api 结果始终以 UTF-8 编码，您甚至可以从其 HTTP Content-Type header 中手动读取:
