Question

在Google API控制台中，API访问会为server，browser，Android和iOS生成密钥。

从Google App Engine Python生成地理编码需要哪种类型的api_key？
如果答案是服务器，我是否需要找出GAE的服务器IP地址，它们是什么？我得到了74.125.129.141，这可能会改变。（或者会吗？）
如果你有一个Python GAE服务器，你能帮我找一个生成代码的例子吗？我不确定我做对了吗？

我有此代码，显示data中的result.content。我的目的是使用ndb.GeoPt(lat,lng)：

def get_geo(address):
  browser_key = "browser_key"
  server_key = "server_key"
  address = cgi.escape(address.replace(" ","+"))
  sensor = "true"
  url = "http://maps.googleapis.com/maps/api/geocode/json?key="+ server_key +"&address=" + address + "&sensor="+ sensor
  result = urlfetch.fetch(url)
  data = json.loads(result.content) # This is the error
  geo = data
  #lat = data['results'][0]['geometry']['location']['lat']
  #long = data['results'][0]['geometry']['location']['lng']
  #return ndb.GeoPt(str(lat) +","+ str(long))
  return geo

使用上面的示例时出现此错误：

  File "C:\xampp\htdocs\mapjobs\main.py", line 18, in get_geo
    data = json.loads(result.content)
  File "C:\Python27\lib\json\__init__.py", line 310, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 346, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python27\lib\json\decoder.py", line 364, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

它应包含browser_key，网址应为：

url = "http://maps.googleapis.com/maps/api/geocode/json?key="+ browser_key +"&address=" + address + "&sensor="+ sensor
