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