实时空气质量

平台: API iOS Android

实时空气质量API，支持中国3000+市县区以及1700+国控站点实时空气质量的查询，包括AQI数值、空气质量等级、首要污染物、PM10、PM2.5、臭氧、二氧化氮、二氧化硫、一氧化碳数值。

注意：空气质量API v1（新版）现已发布，请尝试使用并升级到新版本。

请求URL 

https://api.qweather.com/v7/air/now

如果是免费订阅，将上述API Host更改为devapi.qweather.com。参考免费订阅可用的数据。

请求参数

请求参数包括必选和可选参数，参数之间使用&进行分隔。

  • location(必选)需要查询地区的LocationID或以英文逗号分隔的经度,纬度坐标（十进制，最多支持小数点后两位），LocationID可通过GeoAPI获取。例如 location=101010100 或 location=116.41,39.92
  • lang多语言设置，请阅读多语言文档，了解我们的多语言是如何工作、如何设置以及数据是否支持多语言。

请求示例 

curl -X GET --compressed \
-H 'Authorization: Bearer your_token' \
