第二周周总结

2020.02.29

本周主要内容：通过项目河北创新项目年报平台系统，其需要同一规范填报单位所在行政区划，解：通过调用百度地图API，来获取已知地域的所属行政区，例如 北京市环境卫生设计科学研究所  其所定位为：北京市朝阳区

其思路为首先通过百度api来获取该地域的经度和纬度，再根据经度纬度来识别其所在的行政区划

 public static String getDiyu(String lat,String lng){//已知经纬度，传参给该方法通过调用百度API识别出所属行政区
           String location1="";
          String url="http://api.map.baidu.com/reverse_geocoding/v3/?ak=ld0uqubVfSTAUlXH5qIMN2F3Snsp16LU&output=xml&coordtype=wgs84ll&location="+lat+","+lng;
