GeoCode

查询地点信息_高德地图

介绍

• 通过高德地图的 http://restapi.amap.com/v3/geocode/geo 接口获取省市等地区的详细信息.
• 示例: http://restapi.amap.com/v3/geocode/geo?key=7bb32daa7da4c202280232aeb5606cf9&s=rsv3&address=中关村 获取中关村详细信息

流程

1. 从文件中读取要查询的地点列表
2. 调用高德接口,获取查询到的地点的详细信息
3. 解析, 然后保存到Mongo.

注意

1. 编码问题(demo使用的 Python2.7)

代码
