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'].
;
}
}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 = $cityweatherresult['result'];
echo =======当前天气实况=======
;
echo 温度:.$data['sk']['temp']. ;
echo 风向:.$data['sk']['wind_direction']. (.$data['sk']['wind_strength'].);
echo 湿度:.$data['sk']['humidity']. ;
echo
;
echo =======未来几天天气预报=======
;
foreach($data['future'] as $wkey =>$f){
echo 日期:.$f['date']. .$f['week']. .$f['weather']. .$f['temperature'].
;
}
echo
;
echo =======相关天气指数=======
;
echo 穿衣指数:.$data['today']['dressing_index']. , .$data['today']['dressing_advice'].
;
echo 紫外线强度:.$data['today']['uv_index'].
;
echo 舒适指数:.$data['today']['comfort_index'].
;
echo 洗车指数:.$data['today']['wash_index'];
echo
;
}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=======
;
echo $data['today']['city'];
echo
;
echo =======当前天气实况=======
;
echo 温度:.$data['sk']['temp']. ;
echo 风向:.$data['sk']['wind_direction']. (.$data['sk']['wind_strength'].);
echo 湿度:.$data['sk']['humidity']. ;
echo
;
echo =======未来几天天气预报=======
;
foreach($data['future'] as $wkey =>$f){
echo 日期:.$f['date']. .$f['week']. .$f['weather']. .$f['temperature'].
;
}
echo
;
echo =======相关天气指数=======
;
echo 穿衣指数:.$data['today']['dressing_index']. , .$data['today']['dressing_advice'].
;
echo 紫外线强度:.$data['today']['uv_index'].
;
echo 舒适指数:.$data['today']['comfort_index'].
;
echo 洗车指数:.$data['today']['wash_index'];
echo
;
}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=======
;
echo $data['today']['city'];
echo
;
echo =======当前天气实况=======
;
echo 温度:.$data['sk']['temp']. ;
echo 风向:.$data['sk']['wind_direction']. (.$data['sk']['wind_strength'].);
echo 湿度:.$data['sk']['humidity']. ;
echo
;
echo =======未来几天天气预报=======
;
foreach($data['future'] as $wkey =>$f){
echo 日期:.$f['date']. .$f['week']. .$f['weather']. .$f['temperature'].
;
}
echo
;
echo =======相关天气指数=======
;
echo 穿衣指数:.$data['today']['dressing_index']. , .$data['today']['dressing_advice'].
;
echo 紫外线强度:.$data['today']['uv_index'].
;
echo 舒适指数:.$data['today']['comfort_index'].
;
echo 洗车指数:.$data['today']['wash_index'];
echo
;
}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].
;
}
}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。
