php日历天气预报PHP挪用全国气象预告接口查询气象示例

本代码示例是基于PHP的聚合数据全国景象预报API做事要求的代码样例，利用前你须要：

①：通过https://www.juhe.cn/docs/api/id/39 申请一个景象预报API的appkey

样例代码包含了获取支持城市列表、根据城市获取景象预报、根据IP地址要求景象预报、根据GPS坐标要求景象、城市3小时景象预报的实现。
示例代码紧张是解析一些常用字段，如须要完全或其他未包含的字段，可以自行参考官方的接口，进行修正。

首先：引入封装好的景象调用类

header('Content-type:text/html;charset=utf-8');include 'class.juhe.weather.php'; //引入景象要求类//接口基本信息配置$appkey = ''; //您申请的景象查询appkey$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革，大家可以获取到列表后内置到自己的运用中，就不用每次都去要求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 \"大众ID：\公众.$c['id'].\公众,省份：\"大众.$c['province'].\"大众,城市：\"大众.$c['city'].\"大众,区域：\"大众.$c['district'].\公众 \"大众; }}else{ //以下可根据实际业务需求，自行改写 echo $citysResult['error_code'].\"大众:\"大众.$citysResult['reason'];}

二、根据城市/ID获取景象预报

通过城市的名称或城市的ID来获取景象预报，城市id便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 = $cityWeatherResult['result']; echo \"大众=======当前景象实况======= \"大众; echo \"大众温度：\公众.$data['sk']['temp'].\"大众 \"大众; echo \"大众风向：\公众.$data['sk']['wind_direction'].\"大众（\"大众.$data['sk']['wind_strength'].\公众）\公众; echo \"大众湿度：\"大众.$data['sk']['humidity'].\"大众 \公众; echo \"大众 \"大众; echo \公众=======未来几天景象预报======= \"大众; foreach($data['future'] as $wkey =>$f){ echo \公众日期:\"大众.$f['date'].\"大众 \"大众.$f['week'].\"大众 \"大众.$f['weather'].\"大众 \"大众.$f['temperature'].\公众 \"大众; } echo \"大众 \"大众; echo \"大众=======干系景象指数======= \"大众; echo \"大众穿衣指数：\"大众.$data['today']['dressing_index'].\"大众 , \公众.$data['today']['dressing_advice'].\"大众 \"大众; echo \公众紫外线强度：\"大众.$data['today']['uv_index'].\"大众 \"大众; echo \"大众舒适指数：\公众.$data['today']['comfort_index'].\"大众 \公众; echo \"大众洗车指数：\公众.$data['today']['wash_index']; echo \"大众 \"大众;}else{ echo $cityWeatherRe}

三、根据用户的IP地址要求对应的景象预报

通过用户的IP地址获取用户所在地的景象预报，由于IP地址解析可能会有偏差，以是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 \"大众=======当前城市======= \公众; echo $data['today']['city']; echo \"大众 \"大众; echo \"大众=======当前景象实况======= \"大众; echo \"大众温度：\"大众.$data['sk']['temp'].\公众 \公众; echo \"大众风向：\公众.$data['sk']['wind_direction'].\"大众（\"大众.$data['sk']['wind_strength'].\"大众）\"大众; echo \"大众湿度：\"大众.$data['sk']['humidity'].\"大众 \"大众; echo \公众 \公众; echo \"大众=======未来几天景象预报======= \公众; foreach($data['future'] as $wkey =>$f){ echo \公众日期:\"大众.$f['date'].\"大众 \"大众.$f['week'].\"大众 \公众.$f['weather'].\"大众 \"大众.$f['temperature'].\"大众 \"大众; } echo \"大众 \公众; echo \"大众=======干系景象指数======= \"大众; echo \"大众穿衣指数：\"大众.$data['today']['dressing_index'].\公众 , \"大众.$data['today']['dressing_advice'].\"大众 \"大众; echo \公众紫外线强度：\"大众.$data['today']['uv_index'].\公众 \公众; echo \"大众舒适指数：\公众.$data['today']['comfort_index'].\"大众 \"大众; echo \"大众洗车指数：\公众.$data['today']['wash_index']; echo \"大众 \"大众;}else{ echo $ipWeatherResult['error_code'].\"大众:\"大众.$ipWeatherResult['reason'];}

四、根据GPS坐标来获取对应地区的景象

无论通过二、三、四获取的景象预报，由于聚合格式都是统一的，以是解析的流程是同等的，以是没有额外的操作，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 \公众=======当前城市======= \公众; echo $data['today']['city']; echo \"大众 \"大众; echo \公众=======当前景象实况======= \"大众; echo \"大众温度：\"大众.$data['sk']['temp'].\"大众 \"大众; echo \"大众风向：\"大众.$data['sk']['wind_direction'].\"大众（\"大众.$data['sk']['wind_strength'].\"大众）\公众; echo \公众湿度：\"大众.$data['sk']['humidity'].\"大众 \"大众; echo \"大众 \"大众; echo \"大众=======未来几天景象预报======= \公众; foreach($data['future'] as $wkey =>$f){ echo \公众日期:\公众.$f['date'].\"大众 \"大众.$f['week'].\"大众 \公众.$f['weather'].\"大众 \公众.$f['temperature'].\公众 \"大众; } echo \公众 \公众; echo \公众=======干系景象指数======= \"大众; echo \"大众穿衣指数：\"大众.$data['today']['dressing_index'].\公众 , \"大众.$data['today']['dressing_advice'].\公众 \公众; echo \公众紫外线强度：\"大众.$data['today']['uv_index'].\"大众 \公众; echo \"大众舒适指数：\"大众.$data['today']['comfort_index'].\公众 \"大众; echo \"大众洗车指数：\公众.$data['today']['wash_index']; echo \公众 \"大众;}else{ echo $geoWeatherResult['error_code'].\"大众:\"大众.$geoWeatherResult['reason'];}

五、获取城市三小时预报

便是城市每3小时的景象情形

$forecastResult = $weather->getForecast(\"大众苏州\公众);if($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 => $d){ echo \"大众日期：\"大众.$d['date'].\"大众 (\"大众.$d['sh'].\"大众点-\公众.$d['eh'].\"大众点) \"大众.$d['weather'].\公众 \"大众.$d['temp1'].\"大众~\"大众.$d[\"大众temp2\"大众].\"大众 \"大众; }}else{ //以下可根据实际业务需求，自行改写 ////////////////////////////////////////////////////////////////////// echo $forecastResult['error_code'].\"大众:\"大众.$forecastResult['reason'];}

通过上面的示例代码，大家该当对如果调用聚合数据景象预报API有了一个大体的理解。

末了放上class.juhe.weather.php完全代码：
