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：
/apistore/weatherservice/recentweathers
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 2private 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 $url = /apistore/weatherservice/recentweathers?cityname=.$city;15 $header = array(16apikey: 6512ad3a465e3a9e3d0d1da56639626c,17 );18 curl_setopt($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[ etData][city];24 $citydate=$data[ etData][ oday][date];25 $cityweek=$data[ etData][ oday][week];26 $citytemp=$data[ etData][ oday][curTemp];27 $citypm=$data[ etData][ oday][aqi];28 $cityhightemp=$data[ etData][ oday][hightemp];29 $citylowtemp=$data[ etData][ oday][lowtemp];30 $citytype=$data[ etData][ oday][ ype];31 $cityfengli=$data[ etData][ oday][fengli];32 $cityfengxiang=$data[ etData][ oday][fengxiang];33 $cityforecast=$data[ etData][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."

查询格式：“天气 城市名”
