National Weather Forecast Data Interface Calling PHP Example
Oct 22, 2016 am 12:00 AM
Code sample for PHP-based aggregated data national weather forecast API service request
This code sample is a code sample for PHP-based aggregate data national weather forecast API service request. Before using it, you need:
①: Apply for a weather forecast API appkey through https://www.juhe.cn/docs/api/id/39
The sample code includes the implementation of obtaining the list of supported cities, obtaining the weather forecast based on the city, requesting the weather forecast based on the IP address, requesting the weather based on the GPS coordinates, and the 3-hour weather forecast for the city. The sample code mainly parses some common fields. If you need complete or other fields not included, you can refer to the official interface and make modifications.
First: introduce the encapsulated weather calling class header('Content-type:text/html;charset=utf-8'); <br>
include 'class.juhe.weather.php'; //Introduce weather request class <br>
<br>
//Interface basic information configuration <br>
$appkey = '************'; //The weather query appkey you applied for <br>
$weather = new weather($appkey); 1. Get the list of supported cities
Since the list of supported cities will basically not change like this, you can get the list and build it into your own application, so you don't have to request the API every time. $citysResult = $weather->getCitys(); <br>
if($citysResult['error_code'] == 0){ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
$citys = $citysResult['result']; <br>
foreach($citys as $ckey =>$c){ <br>
echo "ID: ".$c['id'].", Province: ".$c['province'].", City: ".$c['city'].", Region: ".$c ['district']."<br>"; <br>
} <br>
}else{ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
echo $citysResult['error_code'].":".$citysResult['reason']; <br>
} 2. Get weather forecast based on city/ID
Get the weather forecast through the name of the city or the ID of the city. The city ID is the field ID returned in the city support list $cityWeatherResult = $weather->getWeather('Suzhou'); <br>
if($cityWeatherResult['error_code'] == 0){ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
$data = $cityWeatherResult['result']; <br>
Echo "=======Current weather conditions=======<br>"; <br>
echo "Temperature: ".$data['sk']['temp']." "; <br>
echo "Wind direction: ".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; <br>
echo "Humidity:".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======Weather forecast for the next few days=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "Date:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."< br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "========Related weather index=======<br>"; <br>
echo "Dressing index: ".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br>echo "UV intensity:".$data['today']['uv_index']."<br>"; <br>
echo "Comfort index:".$data['today']['comfort_index']."<br>"; <br>
echo "Car wash index:".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
Echo $cityWeatherRe3. Request the corresponding weather forecast based on the user’s IP address
The weather forecast for the user's location is obtained through the user's IP address. Since there may be errors in IP address resolution, sometimes the city located is not necessarily the user's actual location. $ipWeatherResult = $weather->getWeatherByIP('58.215.154.128'); <br>
if($ipWeatherResult['error_code'] == 0){ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
$data = $ipWeatherResult['result']; <br>
Echo "========Current city=======<br>"; <br>
Echo $data['today']['city']; <br>
echo "<br><br>"; <br>
Echo "=======Current weather conditions=======<br>"; <br>
echo "Temperature: ".$data['sk']['temp']." "; <br>
echo "Wind direction: ".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; <br>
echo "Humidity:".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======Weather forecast for the next few days=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "Date:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."< br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "========Related weather index=======<br>"; <br>
echo "Dressing index: ".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br>
echo "UV intensity:".$data['today']['uv_index']."<br>"; <br>
echo "Comfort index:".$data['today']['comfort_index']."<br>"; <br>
echo "Car wash index:".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
echo $ipWeatherResult['error_code'].":".$ipWeatherResult['reason']; <br>
} 4. Get the weather in the corresponding area based on GPS coordinates
Regardless of the weather forecast obtained through 2, 3, or 4, because the aggregation format is unified, the parsing process is consistent, so there are no additional operations, except for some differences in parameter transmission. $geoWeatherResult = $weather->getWeatherByGeo(116.401394,39.916042); <br>
if($geoWeatherResult['error_code'] == 0){ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>$data = $geoWeatherResult['result']; <br>
Echo "========Current city=======<br>"; <br>
Echo $data['today']['city']; <br>
echo "<br><br>"; <br>
Echo "=======Current weather conditions=======<br>"; <br>
echo "Temperature: ".$data['sk']['temp']." "; <br>
echo "Wind direction: ".$data['sk']['wind_direction']." (".$data['sk']['wind_strength'].")"; <br>
echo "Humidity:".$data['sk']['humidity']." "; <br>
echo "<br><br>"; <br>
<br>
echo "=======Weather forecast for the next few days=======<br>"; <br>
foreach($data['future'] as $wkey =>$f){ <br>
echo "Date:".$f['date']." ".$f['week']." ".$f['weather']." ".$f['temperature']."< br>"; <br>
} <br>
echo "<br><br>"; <br>
<br>
echo "========Related weather index=======<br>"; <br>
echo "Dressing index: ".$data['today']['dressing_index']." , ".$data['today']['dressing_advice']."<br>"; <br>
echo "UV intensity:".$data['today']['uv_index']."<br>"; <br>
echo "Comfort index:".$data['today']['comfort_index']."<br>"; <br>
echo "Car wash index:".$data['today']['wash_index']; <br>
echo "<br><br>"; <br>
<br>
}else{ <br>
echo $geoWeatherResult['error_code'].":".$geoWeatherResult['reason']; <br>
} 5. Get the three-hour city forecast
It is the city’s weather conditions every 3 hours $forecastResult = $weather->getForecast("Suzhou"); <br>
if($forecastResult['error_code'] == 0){ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
$data = $forecastResult['result']; <br>
foreach($data as $key => $d){ <br>
echo "Date:".$d['date']." (".$d['sh']."point-".$d['eh']."point) ".$d['weather' ]." ".$d['temp1']."~".$d["temp2"]."<br>"; <br>
} <br>
}else{ //The following can be rewritten according to actual business needs <br>
///////////////////////////////////////////////////// ///////////////////// <br>
echo $forecastResult['error_code'].":".$forecastResult['reason']; <br>
} Through the above sample code, everyone should have a general understanding of how to call the aggregated data weather forecast API.

Guidance and Examples: Learn to implement the selection sort algorithm in Java
Feb 18, 2024 am 10:52 AM
Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
