主要记录一些日常开发中可以使用到的一些免费api接口,目前包括 ip地址查询、天气查询
通过 IP 查询地址
ip-api (不支持 https)
💡 api接口文档
🕹 调用接口
$ curl http://ip-api.com/json
📝 返回信息(位置信息,服务器的经纬度、时区)

百度地图api (支持HTTP/HTTPS)
相对于上面提到的两个api,百度地图api适合在国内使用,不支持海外场景,返回的经纬度坐标是当前城市中心点,使用时需要先申请AK,获取到国内的详细地址信息,在有些场景下还是很有用的。如果使用场景需要精确的经纬度,可以再调用一个 百度api 的 地理编码,使用详细地址转换到对应经纬度。

🗝 申请AK
创建应用
在创建应用时候可以勾选全部的基础服务
需要注意的是:ip白名单不建议使用 0.0.0.0/0 可以使用具体的ip名称。
天气查询 API
使用百度开放API,必须搭配AK使用,AK的获取方法上面已经提到了。
