公眾號天氣查詢介面執行個體，公眾天氣查詢執行個體

這是來自百度API的一個天氣查詢的介面，支援曆史7天和未來4天的天氣情況查詢，介面不錯，分享給大家。

介面申請地址：http://apistore.baidu.com/apiworks/servicedetail/112.html

首先，擷取一下apikey（貌似需要手機驗證碼認證下）

我調用的是曆史7天和未來4天的介面，介面地址是：

http://apis.baidu.com/apistore/weatherservice/recentweathers

我將這個天氣查詢的功能整合在了公眾平台上，支援未來4天天氣查詢，包括：當前溫度、pm值、風向、風力、最高溫度、最低溫度、天氣狀態的查詢，效果如下：

閑話不多說，我就喜歡來點直接的，核心代碼如下：

 1 //接收到文本資訊 2     private function receiveText($object){ 3         //多個空格縮為一個 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]=="天氣"){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                 $out="今日溫度：".$citylowtemp."~".$cityhightemp."\n\r"."當前溫度：".$citytemp."\n\r"."天氣情況：".$citytype."\n\r"."PM2.5值：".$citypm."\n\r風向風力：".$cityfengxiang."
