這篇文章主要為大家展示了“PHP如何調(diào)用全國天氣預(yù)報數(shù)據(jù)接口進(jìn)行查詢天氣”，內(nèi)容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領(lǐng)大家一起研究并學(xué)習(xí)一下“PHP如何調(diào)用全國天氣預(yù)報數(shù)據(jù)接口進(jìn)行查詢天氣”這篇文章吧。
本文實例講述了PHP調(diào)用全國天氣預(yù)報數(shù)據(jù)接口查詢天氣。分享給大家供大家參考，具體如下：
基于PHP的聚合數(shù)據(jù)全國天氣預(yù)報API服務(wù)請求的代碼樣例
本代碼示例是基于PHP的聚合數(shù)據(jù)全國天氣預(yù)報API服務(wù)請求的代碼樣例，使用前你需要：
①：通過https://www.juhe.cn/docs/api/id/39 申請一個天氣預(yù)報API的appkey
樣例代碼包含了獲取支持城市列表、根據(jù)城市獲取天氣預(yù)報、根據(jù)IP地址請求天氣預(yù)報、根據(jù)GPS坐標(biāo)請求天氣、城市3小時天氣預(yù)報的實現(xiàn)。示例代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(jìn)行修改。
首先：引入封裝好的天氣調(diào)用類
header('Content-type:text/html;charset=utf-8');
include 'class.juhe.weather.php'; //引入天氣請求類
//接口基本信息配置
$appkey = '**********'; //您申請的天氣查詢appkey
$weather = new weather($appkey);一、獲取支持的城市列表
由于支持的城市列表基本不會這么變化，大家可以獲取到列表后內(nèi)置到自己的應(yīng)用中，就不用每次都去請求API。
$citysResult = $weather->getCitys();
if($citysResult['error_code'] == 0){ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
$citys = $citysResult['result'];
foreach($citys as $ckey =>$c){
echo "ID：".$c['id'].",省份：".$c['province'].",城市：".$c['city'].",區(qū)域：".$c['district']."<br>";
}
}else{ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
echo $citysResult['error_code'].":".$citysResult['reason'];
}二、根據(jù)城市/ID獲取天氣預(yù)報
通過城市的名稱或城市的ID來獲取天氣預(yù)報，城市id就是獲取城市支持列表中返回的字段ID
$cityWeatherResult = $weather->getWeather('蘇州');
if($cityWeatherResult['error_code'] == 0){ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
$data = $cityWeatherResult['result'];
echo "=======當(dāng)前天氣實況=======<br>";
echo "溫度：".$data['sk']['temp']." ";
echo "風(fēng)向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）";
echo "濕度：".$data['sk']['humidity']." ";
echo "<br><br>";
echo "=======未來幾天天氣預(yù)報=======<br>";
foreach($data['future'] as $wkey =>$f){
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>";
}
echo "<br><br>";
echo "=======相關(guān)天氣指數(shù)=======<br>";
echo "穿衣指數(shù)：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>";
echo "紫外線強(qiáng)度：".$data['today']['uv_index']."<br>";
echo "舒適指數(shù)：".$data['today']['comfort_index']."<br>";
echo "洗車指數(shù)：".$data['today']['wash_index'];
echo "<br><br>";
}else{
echo $cityWeatherRe
}三、根據(jù)用戶的IP地址請求對應(yīng)的天氣預(yù)報
通過用戶的IP地址獲取用戶所在地的天氣預(yù)報，由于IP地址解析可能會有誤差，所以有時定位到的城市不一定是用戶實際的所在地。
$ipWeatherResult = $weather->getWeatherByIP('58.215.154.128');
if($ipWeatherResult['error_code'] == 0){ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
$data = $ipWeatherResult['result'];
echo "=======當(dāng)前城市=======<br>";
echo $data['today']['city'];
echo "<br><br>";
echo "=======當(dāng)前天氣實況=======<br>";
echo "溫度：".$data['sk']['temp']." ";
echo "風(fēng)向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）";
echo "濕度：".$data['sk']['humidity']." ";
echo "<br><br>";
echo "=======未來幾天天氣預(yù)報=======<br>";
foreach($data['future'] as $wkey =>$f){
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>";
}
echo "<br><br>";
echo "=======相關(guān)天氣指數(shù)=======<br>";
echo "穿衣指數(shù)：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>";
echo "紫外線強(qiáng)度：".$data['today']['uv_index']."<br>";
echo "舒適指數(shù)：".$data['today']['comfort_index']."<br>";
echo "洗車指數(shù)：".$data['today']['wash_index'];
echo "<br><br>";
}else{
echo $ipWeatherResult['error_code'].":".$ipWeatherResult['reason'];
}四、根據(jù)GPS坐標(biāo)來獲取對應(yīng)地區(qū)的天氣
無論通過二、三、四獲取的天氣預(yù)報，因為聚合格式都是統(tǒng)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 = $weather->getWeatherByGeo(116.401394,39.916042);
if($geoWeatherResult['error_code'] == 0){ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
$data = $geoWeatherResult['result'];
echo "=======當(dāng)前城市=======<br>";
echo $data['today']['city'];
echo "<br><br>";
echo "=======當(dāng)前天氣實況=======<br>";
echo "溫度：".$data['sk']['temp']." ";
echo "風(fēng)向：".$data['sk']['wind_direction']." （".$data['sk']['wind_strength']."）";
echo "濕度：".$data['sk']['humidity']." ";
echo "<br><br>";
echo "=======未來幾天天氣預(yù)報=======<br>";
foreach($data['future'] as $wkey =>$f){
echo "日期:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."<br>";
}
echo "<br><br>";
echo "=======相關(guān)天氣指數(shù)=======<br>";
echo "穿衣指數(shù)：".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>";
echo "紫外線強(qiáng)度：".$data['today']['uv_index']."<br>";
echo "舒適指數(shù)：".$data['today']['comfort_index']."<br>";
echo "洗車指數(shù)：".$data['today']['wash_index'];
echo "<br><br>";
}else{
echo $geoWeatherResult['error_code'].":".$geoWeatherResult['reason'];
}五、獲取城市三小時預(yù)報
就是城市每3小時的天氣情況
$forecastResult = $weather->getForecast("蘇州");
if($forecastResult['error_code'] == 0){ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
$data = $forecastResult['result'];
foreach($data as $key => $d){
echo "日期：".$d['date']." (".$d['sh']."點-".$d['eh']."點) ".$d['weather']." ".$d['temp1']."~".$d["temp2"]."<br>";
}
}else{ //以下可根據(jù)實際業(yè)務(wù)需求，自行改寫
//////////////////////////////////////////////////////////////////////
echo $forecastResult['error_code'].":".$forecastResult['reason'];
}通過上面的示例代碼，大家應(yīng)該對如果調(diào)用聚合數(shù)據(jù)天氣預(yù)報API有了一個大體的了解。
