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); 22 $data = json_decode($res,true); 23 $cityname=$data['retData']['city']; 24 $citydate=$data['retData']['today']['date']; 25 $cityweek=$data['retData']['today']['week']; 26 $citytemp=$data['retData']['today']['curTemp']; 27 $citypm=$data['retData']['today']['aqi']; 28 $cityhightemp=$data['retData']['today']['hightemp']; 29 $citylowtemp=$data['retData']['today']['lowtemp']; 30 $citytype=$data['retData']['today']['type']; 31 $cityfengli=$data['retData']['today']['fengli']; 32 $cityfengxiang=$data['retData']['today']['fengxiang']; 33 $cityforecast=$data['retData']['forecast']; 34 35 $out="今日温度：".$citylowtemp."~".$cityhightemp."\n\r"."当前温度：".$citytemp."\n\r"."天气情况：".$citytype."\n\r"."PM2.5值：".$citypm."\n\r风向风力：".$cityfengxiang."
