这是来自百度api的一个天气查询的接口，支持历史7天和未来4天的天气情况查询，接口不错，分享给大家。

首先，获取一下apikey（貌似需要手机验证码认证下）

我调用的是历史7天和未来4天的接口，接口地址是：

http:<span style="color: #008000;">//</span><span style="color: #008000;">apis.baidu.com/apistore/weatherservice/recentweathers</span>

我将这个天气查询的功能集成在了微信公众平台上，支持未来4天天气查询，包括：当前温度、pm值、风向、风力、最高温度、最低温度、天气状态的查询，效果如下：

闲话不多说，我就喜欢来点直接的，核心代码如下：
