微信公眾號(hào)天氣查詢接口實(shí)例，公眾天氣查詢實(shí)例

這是來自百度API的一個(gè)天氣查詢的接口，支持歷史7天和未來4天的天氣情況查詢，接口不錯(cuò)，分享給大家。

接口申請地址：http://apistore.baidu.com/apiworks/servicedetail/112.html

首先，獲取一下apikey（貌似需要手機(jī)驗(yàn)證碼認(rèn)證下）

我調(diào)用的是歷史7天和未來4天的接口，接口地址是：

http:<span>//</span><span>apis.baidu.com/apistore/weatherservice/recentweathers</span>

我將這個(gè)天氣查詢的功能集成在了微信公眾平臺(tái)上，支持未來4天天氣查詢，包括：當(dāng)前溫度、pm值、風(fēng)向、風(fēng)力、最高溫度、最低溫度、天氣狀態(tài)的查詢，效果如下：

閑話不多說，我就喜歡來點(diǎn)直接的，核心代碼如下：
