Incluye tus parámetros en el cuerpo de la solicitud. El cuerpo de la solicitud contiene la ubicación para la que deseas obtener información del pronóstico de la calidad del aire por hora y varias opciones para controlar qué información adicional se incluye en la respuesta.
Acerca de las respuestas de previsión
El cuerpo de la respuesta proporciona la fecha y hora en UTC para las que se debe mostrar la información del pronóstico de la calidad del aire, los índices de calidad del aire y la información personalizada adicional. El cuerpo de la respuesta también incluye un token para recuperar la siguiente página si la información no cabe en el tamaño de página solicitado.
Ejemplo de solicitud básica
En el siguiente código, se muestra cómo construir una solicitud de previsión. En este ejemplo, especificas la ubicación, la fecha y la hora (a partir de la próxima hora y hasta 96 horas) para las que se mostrará la información del pronóstico de la calidad del aire por hora.
{"hourlyForecasts":[{"dateTime":"2024-02-09T08:00:00Z","indexes":[{"code":"uaqi","displayName":"Universal AQI","aqi":80,"aqiDisplay":"80","color":{"red":0.34509805,"green":0.74509805,"blue":0.20784314},"category":"Excellent air quality","dominantPollutant":"pm25"}]}],"regionCode":"us"}
Ejemplo de solicitud con varios parámetros
En el siguiente código, se muestra cómo construir un cuerpo de solicitud con varios parámetros. En este ejemplo, debes especificar lo siguiente:
Ubicación
Período para el que se mostrará la información del pronóstico de la calidad del aire
Código de idioma
Cálculos adicionales (como recomendaciones de salud, la concentración del contaminante dominante y la información de contaminantes adicionales)
Esto devuelve la siguiente página de información de previsión:
