微信公众号天气查询接口实例，公众天气查询实例

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。

接口申请地址：http://apistore.baidu.com/apiworks/servicedetail/112.html

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：

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：

 1 //接收到文本信息
 2     private function receiveText($object){
 3         //多个空格缩为一个
 4         $keyword = $object->Content;
 5         $keyword=preg_replace("/\s(?=\s)/","\\1",$keyword);
 6         $funcFlag = 0;
 7         if(strpos($keyword," ")){
 8             //echo '有空格';
 9             $arr = explode(" ",$keyword);
10             if($arr[0]=="天气"){
11                 $dateArray = array();
12                 $ch = curl_init();
13                 $city=urlencode($arr[1]);
14                 $url = 'http://apis.baidu.com/apistore/weatherservice/recentweathers?cityname='.$city;
15                 $header = array(
16                     'apikey: 6512ad3a465e3a9e3d0d1da56639626c',
17                 );
18                 curl_setopt($ch, CURLOPT_HTTPHEADER  , $header);
19                 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
20                 curl_setopt($ch , CURLOPT_URL , $url);
21                 $res = curl_exec($ch);
