PHP调用全国天气预报数据接口查询天气示例
作者:yunmen 时间:2023-11-14 03:11:49
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https://www.juhe.cn/docs/api/id/39 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:
