基於PHP的聚合資料全國天氣預報API服務請求的程式碼範例
本程式碼範例是基於PHP的聚合資料全國天氣預報API服務請求的程式碼範例，使用前你需要：
①：透過https://www.juhe.cn/docs/api/id/39 申請一個天氣預報API的appkey
範例程式碼包含了取得支援城市清單、根據城市取得天氣預報、根據IP位址請求天氣預報、根據GPS座標請求天氣、城市3小時天氣預報的實現。範例程式碼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，可以自行參考官方的接口，進行修改。
首先：引入封裝好的天氣呼叫類別 header('Content-type:text/html;charset=utf-8'); <br>
include 'class.juhe.weather.php'; //引入天氣請求類別 <br>
<br>
//介面基本資訊配置 <br>
$appkey = '**********'; //您申請的天氣查詢appkey <br>
$weather = new weather($appkey); 一、取得支援的城市清單
由於支援的城市清單基本上不會這麼變化，大家可以取得到清單後面內建到自己的應用程式中，就不用每次都去請求API。 $citysResult = $weather->getCitys(); <br>
if($citysResult['error_code'] == 0){ //以下可依實際業務需求，並自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
$citys = $citysResult['result']; <br>
foreach($citys as $ckey =>$c){ <br>
echo "ID：".$c['id'].",省份：".$c['province'].",城市：".$c['city'].",區域：".$c ['district']."<br>"; <br>
} <br>
}else{ //以下可依實際業務需求，自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
echo $citysResult['error_code'].":".$citysResult['reason']; <br>
} 二、依城市/ID取得天氣預報
透過城市的名稱或城市的ID來取得天氣預報，城市id就是取得城市支持清單中回傳的欄位ID $cityWeatherResult = $weather->getWeather('蘇州'); <br>
if($cityWeatherResult['error_code'] == 0){ //以下可依實際業務需求，並自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
$data = $cityWeatherResult['result']; <br>
echo "=======當前天氣實況=======<br>"; <br>
echo "溫度：".$data['sk']['temp']." "; <br>
echo "風向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）"; <br>
echo "濕度：".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======未來幾天天氣預報=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "=======相關天氣指數=======<br>"; <br>
echo "穿衣指數：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br> echo "紫外線強度：".$data['today']['uv_index']."<br>"; <br>
echo "舒適指標：".$data['today']['comfort_index']."<br>"; <br>
echo "洗車指數：".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
echo $cityWeatherRe三、依使用者的IP位址請求對應的天氣預報
透過使用者的IP位址取得使用者所在地的天氣預報，由於IP位址解析可能會有誤差，所以有時定位到的城市不一定是使用者實際的所在地。 $ipWeatherResult = $weather->getWeatherByIP('58.215.154.128'); <br>
if($ipWeatherResult['error_code'] == 0){ //以下可依實際業務需求，並自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
$data = $ipWeatherResult['result']; <br>
echo "=======目前城市=======<br>"; <br>
echo $data['today']['city']; <br>
echo "<br><br>"; <br>
echo "=======當前天氣實況=======<br>"; <br>
echo "溫度：".$data['sk']['temp']." "; <br>
echo "風向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）"; <br>
echo "濕度：".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======未來幾天天氣預報=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "=======相關天氣指數=======<br>"; <br>
echo "穿衣指數：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br>
echo "紫外線強度：".$data['today']['uv_index']."<br>"; <br>
echo "舒適指標：".$data['today']['comfort_index']."<br>"; <br>
echo "洗車指數：".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
echo $ipWeatherResult['error_code'].":".$ipWeatherResult['reason']; <br>
} 四、依據GPS座標來取得對應地區的天氣
無論透過二、三、四取得的天氣預報，因為聚合格式都是統一的，所以解析的流程是一致的，所以沒有額外的操作，只是傳參上有點的差異。 $geoWeatherResult = $weather->getWeatherByGeo(116.401394,39.916042); <br>
if($geoWeatherResult['error_code'] == 0){ //以下可依實際業務需求，並自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br> $data = $geoWeatherResult['result']; <br>
echo "=======目前城市=======<br>"; <br>
echo $data['today']['city']; <br>
echo "<br><br>"; <br>
echo "=======當前天氣實況=======<br>"; <br>
echo "溫度：".$data['sk']['temp']." "; <br>
echo "風向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）"; <br>
echo "濕度：".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======未來幾天天氣預報=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "=======相關天氣指數=======<br>"; <br>
echo "穿衣指數：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br>
echo "紫外線強度：".$data['today']['uv_index']."<br>"; <br>
echo "舒適指標：".$data['today']['comfort_index']."<br>"; <br>
echo "洗車指數：".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
echo $geoWeatherResult['error_code'].":".$geoWeatherResult['reason']; <br>
} 五、取得城市三小時預報
是城市每3小時的天氣狀況 $forecastResult = $weather->getForecast("蘇州"); <br>
if($forecastResult['error_code'] == 0){ //以下可依實際業務需求，並自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
$data = $forecastResult['result']; <br>
foreach($data as $key => $d){ <br>
echo "日期：".$d['date']." (".$d['sh']."點-".$d['eh']."點) ".$d['weather' ]." ".$d['temp1']."~".$d["temp2"]."<br>"; <br>
} <br>
}else{ //以下可依實際業務需求，自行改寫 <br>
////////////////////////////////////////////////// //////////////////// <br>
echo $forecastResult['error_code'].":".$forecastResult['reason']; <br>
} 透過上面的範例程式碼，大家應該對如果呼叫聚合資料天氣預報API有了一個大致的了解。
