关于springboot:SpringBoot整合高德地图-天气查询

jiezi

申请 key

登录高德，注册，增加利用，创立 key

官网 api：

https://lbs.amap.com/api/webs…

调用步骤:
第一步，申请”web 服务 API”密钥（Key）；
第二步，拼接 HTTP 申请 URL，第一步申请的 Key 需作为必填参数一起发送；
第三步，接管 HTTP 申请返回的数据（JSON 或 XML 格局），解析数据。
如无非凡申明，接口的输出参数和输入数据编码全副对立为 UTF-8。

最次要的也是获取到 key

这里获取以后工夫的天气情况与将来天气情况返回数据不一样，所在写了 2 个办法，参数只有一个，城市编码.

1. 获取以后天气
http://localhost:2080/weather/getCurrent?adcode=140200

![在这里插入图片形容](https://mic-blob-bucket.oss-cn-beijing.aliyuncs.com/b2451c2b5d1d4d1aa898d87c80e89dfa.png)

2. 获取将来天气
http://localhost:2080/weather/getFuture?adcode=140200
