通过经纬度转换城市 微信小程序上传腾讯经纬度 通过经纬度转换成城市

 

Java实现调用腾讯地图接口获取行政地区信息

 

开始之前做好如下准备：

腾讯地图API：http://lbs.qq.com/webservice_v1/guide-gcoder.html
腾讯地图秘钥（百度如何获取）：KEY
调用接口：http://apis.map.qq.com/ws/geocoder/v1/?location=39.984154,116.307490&key=OB4BZ-D4W3U-B7VVO-4PJWW-6TKDJ-WPB77&get_poi=1
需要的jar包：
json-lib-2.3-jdk15.jar（我用的是jdk1.8，这个jdk15我暂时不知道是啥，不过我可以正常使用）
commons-beanutils-1.8.0.jar
commons-collections-3.2.1.jar
commons-lang-2.4.jar
commons-logging-1.1.1.jar
ezmorph-1.0.6.jar
我整理好了所需的jar包，这是下载地址：https://download.csdn.net/download/blue_hh/10453610
当然，需要是maven项目的话，就简单粗暴了。以下是maven依赖：
