本文實例講述了PHP調用全國天氣預報數據接口查詢天氣。分享給大家供大家參考,具體如下:
基于PHP的聚合數據全國天氣預報API服務請求的代碼樣例
本代碼示例是基于PHP的聚合數據全國天氣預報API服務請求的代碼樣例,使用前你需要:
①:通過https://www.juhe.cn/docs/api/id/39 申請一個天氣預報API的appkey
樣例代碼包含了獲取支持城市列表、根據城市獲取天氣預報、根據IP地址請求天氣預報、根據GPS坐標請求天氣、城市3小時天氣預報的實現。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,進行修改。
首先:引入封裝好的天氣調用類
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置到自己的應用中,就不用每次都去請求API。
$citysResult = $weather->getCitys(); if($citysResult['error_code'] == 0){ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// $citys = $citysResult['result']; foreach($citys as $ckey =>$c){ echo "ID:".$c['id'].",省份:".$c['province'].",城市:".$c['city'].",區域:".$c['district']."<br>"; } }else{ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// echo $citysResult['error_code'].":".$citysResult['reason']; }
二、根據城市/ID獲取天氣預報
通過城市的名稱或城市的ID來獲取天氣預報,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){ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// $data = $cityWeatherResult['result']; echo "=======當前天氣實況=======<br>"; echo "溫度:".$data['sk']['temp']." "; echo "風向:".$data['sk']['wind_direction']." (".$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 "=======相關天氣指數=======<br>"; echo "穿衣指數:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外線強度:".$data['today']['uv_index']."<br>"; echo "舒適指數:".$data['today']['comfort_index']."<br>"; echo "洗車指數:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $cityWeatherRe }
三、根據用戶的IP地址請求對應的天氣預報
通過用戶的IP地址獲取用戶所在地的天氣預報,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){ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// $data = $ipWeatherResult['result']; echo "=======當前城市=======<br>"; echo $data['today']['city']; echo "<br><br>"; echo "=======當前天氣實況=======<br>"; echo "溫度:".$data['sk']['temp']." "; echo "風向:".$data['sk']['wind_direction']." (".$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 "=======相關天氣指數=======<br>"; echo "穿衣指數:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外線強度:".$data['today']['uv_index']."<br>"; echo "舒適指數:".$data['today']['comfort_index']."<br>"; echo "洗車指數:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $ipWeatherResult['error_code'].":".$ipWeatherResult['reason']; }
四、根據GPS坐標來獲取對應地區的天氣
無論通過二、三、四獲取的天氣預報,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 = $weather->getWeatherByGeo(116.401394,39.916042); if($geoWeatherResult['error_code'] == 0){ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// $data = $geoWeatherResult['result']; echo "=======當前城市=======<br>"; echo $data['today']['city']; echo "<br><br>"; echo "=======當前天氣實況=======<br>"; echo "溫度:".$data['sk']['temp']." "; echo "風向:".$data['sk']['wind_direction']." (".$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 "=======相關天氣指數=======<br>"; echo "穿衣指數:".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; echo "紫外線強度:".$data['today']['uv_index']."<br>"; echo "舒適指數:".$data['today']['comfort_index']."<br>"; echo "洗車指數:".$data['today']['wash_index']; echo "<br><br>"; }else{ echo $geoWeatherResult['error_code'].":".$geoWeatherResult['reason']; }
五、獲取城市三小時預報
就是城市每3小時的天氣情況
$forecastResult = $weather->getForecast("蘇州"); if($forecastResult['error_code'] == 0){ //以下可根據實際業務需求,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{ //以下可根據實際業務需求,自行改寫 ////////////////////////////////////////////////////////////////////// echo $forecastResult['error_code'].":".$forecastResult['reason']; }
通過上面的示例代碼,大家應該對如果調用聚合數據天氣預報API有了一個大體的了解。
最后放上class.juhe.weather.php完整代碼:
