如果您想使用Google Maps API来查看其REST API，则无需安装Google Maps API，只需发送以下请求即可

If you want to use the Google Maps API have a look at their REST API, you don't need to install a Google Maps API just send a Request like

http://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true_or_false

and you will get a response XML.

对于响应JSON:
