PHP调用全国天气预报数据接口查询天气示例
本文实例讲述了php调用全国天气预报数据接口查询天气。分享给大家供大家参考,具体如下:
基于php的聚合数据全国天气预报api服务请求的代码样例
本代码示例是基于php的聚合数据全国天气预报api服务请求的代码样例,使用前你需要:
①:通过 申请一个天气预报api的appkey
样例代码包含了获取支持城市列表、根据城市获取天气预报、根据ip地址请求天气预报、根据gps坐标请求天气、城市3小时天气预报的实现。示例代码主要是解析一些常用字段,如需要完整或其他未包含的字段,可以自行参考官方的接口,进行修改。
首先:引入封装好的天气调用类
header('content-type:text/html;charset=utf-8'); include 'class.juhe.weather.php'; //引入天气请求类 //接口基本信息配置 $appkey = '**********'; //您申请的天气查询appkey $weather = new weather($appkey);
一、获取支持的城市列表
由于支持的城市列表基本不会这么变化,大家可以获取到列表后内置到自己的应用中,就不用每次都去请求api。
$citysresult = $weather->getcitys(); if($citysresult['error_code'] == 0){ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// $citys = $citysresult['result']; foreach($citys as $ckey =>$c){ echo "id:".$c['id'].",省份:".$c['province'].",城市:".$c['city'].",区域:".$c['district']."<br>"; } }else{ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// echo $citysresult['error_code'].":".$citysresult['reason']; }
二、根据城市/id获取天气预报
通过城市的名称或城市的id来获取天气预报,城市id就是获取城市支持列表中返回的字段id
$cityweatherresult = $weather->getweather('苏州'); if($cityweatherresult['error_code'] == 0){ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// $data = $cityweatherresult['result']; echo "=======当前天气实况=======<br>"; echo "温度:".$data['sk']['temp']." "; echo "风向:".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; echo "湿度:".$data['sk']['humidity']." "; echo "<br><br>"; echo "=======未来几天天气预报=======<br>"; foreach($data['future'] as $wkey =>$f){ echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; } echo "<br><br>"; echo "=======相关天气指数=======<br>"; echo "穿衣指数:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外线强度:".$data['today']['uv_index']."<br>"; echo "舒适指数:".$data['today']['comfort_index']."<br>"; echo "洗车指数:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $cityweatherre }
三、根据用户的ip地址请求对应的天气预报
通过用户的ip地址获取用户所在地的天气预报,由于ip地址解析可能会有误差,所以有时定位到的城市不一定是用户实际的所在地。
$ipweatherresult = $weather->getweatherbyip('58.215.154.128'); if($ipweatherresult['error_code'] == 0){ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// $data = $ipweatherresult['result']; echo "=======当前城市=======<br>"; echo $data['today']['city']; echo "<br><br>"; echo "=======当前天气实况=======<br>"; echo "温度:".$data['sk']['temp']." "; echo "风向:".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; echo "湿度:".$data['sk']['humidity']." "; echo "<br><br>"; echo "=======未来几天天气预报=======<br>"; foreach($data['future'] as $wkey =>$f){ echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; } echo "<br><br>"; echo "=======相关天气指数=======<br>"; echo "穿衣指数:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外线强度:".$data['today']['uv_index']."<br>"; echo "舒适指数:".$data['today']['comfort_index']."<br>"; echo "洗车指数:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $ipweatherresult['error_code'].":".$ipweatherresult['reason']; }
四、根据gps坐标来获取对应地区的天气
无论通过二、三、四获取的天气预报,因为聚合格式都是统一的,所以解析的流程是一致的,所以没有额外的操作,只是传参上有点的差异。
$geoweatherresult = $weather->getweatherbygeo(116.401394,39.916042); if($geoweatherresult['error_code'] == 0){ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// $data = $geoweatherresult['result']; echo "=======当前城市=======<br>"; echo $data['today']['city']; echo "<br><br>"; echo "=======当前天气实况=======<br>"; echo "温度:".$data['sk']['temp']." "; echo "风向:".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; echo "湿度:".$data['sk']['humidity']." "; echo "<br><br>"; echo "=======未来几天天气预报=======<br>"; foreach($data['future'] as $wkey =>$f){ echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; } echo "<br><br>"; echo "=======相关天气指数=======<br>"; echo "穿衣指数:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外线强度:".$data['today']['uv_index']."<br>"; echo "舒适指数:".$data['today']['comfort_index']."<br>"; echo "洗车指数:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $geoweatherresult['error_code'].":".$geoweatherresult['reason']; }
五、获取城市三小时预报
就是城市每3小时的天气情况
$forecastresult = $weather->getforecast("苏州"); if($forecastresult['error_code'] == 0){ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// $data = $forecastresult['result']; foreach($data as $key => $d){ echo "日期:".$d['date']." (".$d['sh']."点-".$d['eh']."点) ".$d['weather']." ".$d['temp1']."~".$d["temp2"]."<br>"; } }else{ //以下可根据实际业务需求,自行改写 ////////////////////////////////////////////////////////////////////// echo $forecastresult['error_code'].":".$forecastresult['reason']; }
通过上面的示例代码,大家应该对如果调用聚合数据天气预报api有了一个大体的了解。
最后放上class.juhe.weather.php完整代码:
