百度地图Geocoding接口（可用于地理编码和逆地理编码）
Geocoding API 是一类简单的HTTP接口，用于提供从地址到经纬度坐标或者从经纬度坐标到地址的转换服务，用户可以使用C# 、C++、Java等开发语言发送HTTP请求且接收JSON、XML的返回数据。
Geocoding API包括地址解析和逆地址解析功能。
- 地理编码：即地址解析，由详细到街道的结构化地址得到百度经纬度信息，且支持名胜古迹、标志性建筑名称直接解析返回百度经纬度。例如：“北京市海淀区中关村南大街27号”地址解析的结果是“lng:116.31985,lat:39.959836”，“百度大厦”地址解析的结果是“lng:116.30815,lat:40.056885”
- 逆地理编码，即逆地址解析，由百度经纬度信息得到结构化地址信息。例如：“lat:31.325152,lng:120.558957”逆地址解析的结果是“江苏省苏州市虎丘区塔园路318号”。
