Question

我想创建java天气应用程序。

我有Open Weather的代码和API，但我没有jar文件。

这是我的代码

public class WeatherTest {

    public static final void main(String[] args) {
        boolean isMetric = true;
        String owmApiKey = "XXXXXXXXXXXX";

        /* YOUR OWM API KEY HERE */
        String weatherCity = "Brisbane,AU";
        byte forecastDays = 3;
        OpenWeatherMap.Units units = (isMetric)
            ? OpenWeatherMap.Units.METRIC
            : OpenWeatherMap.Units.IMPERIAL;
        OpenWeatherMap owm = new OpenWeatherMap(units, owmApiKey);
        try {
            DailyForecast forecast = owm.dailyForecastByCityName(weatherCity, forecastDays);
            System.out.println("Weather for: " + forecast.getCityInstance().getCityName());
            int numForecasts = forecast.getForecastCount();

            for (int i = 0; i < numForecasts; i++) {
                DailyForecast.Forecast dayForecast = forecast.getForecastInstance(i);
                DailyForecast.Forecast.Temperature temperature = dayForecast.getTemperatureInstance();
                System.out.println("\t" + dayForecast.getDateTime());
                System.out.println("\tTemperature: " + temperature.getMinimumTemperature()
                    + " to " + temperature.getMaximumTemperature() + "\n");
            }
        } catch (IOException | JSONException e) {
        e.printStackTrace();
        }
    }
}

OpenWeatherMap提供了一个REST API，您可以调用它来获取天气数据。有关API规范，请参阅https://openweathermap.org/api。

为了使用Java代码调用它，您必须实现REST Java客户端。有很多方法可以做到这一点，但首先，您可以参考https://www.mkyong.com/webservices/jax-rs/restfull-java-client-with-java-net-url/

或者，有许多客户开发了围绕OpenWeatherMap API。您可以在https://github.com/search?p=1&q=openweathermap&ref=cmdform&type=Repositories

进行搜索

由于您正在寻找Java，我建议您查看https://github.com/xSAVIKx/openweathermap-java-api。

此库位于https://github.com/xSAVIKx/openweathermap-java-api/blob/master/api-examples/src/main/java/org/openweathermap/api/example/DailyForecastExample.java

，可以使用此示例

哪里可以找到OpenWeatherMap jar？
