记录一些免费的 API接口

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。

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。
