yql - 使用 Yql 查询 lat,long parms 获取天气信息

Question

我正在使用以下 YQL 查询来获取天气信息

http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3D%2248907%22&format=json

有没有办法使用经度、纬度作为 YQL 查询参数来获取天气信息。

Answer 1

You could use a sub-select to go from a latitude/longitude pair to a WOEID like

SELECT * FROM weather.woeid 
WHERE w IN (
    SELECT place.woeid 
    FROM flickr.places(1) 
    WHERE (lat,lon) in (55.948503,-3.198931)
);

(Try in YQL console)

Answer 2

这对我有用：

...

query = "SELECT * FROM weather.forecast " +
            "WHERE woeid in (" +
            "SELECT woeid " +
            "FROM geo.places(1) " +
            "WHERE text=\"(%1$s,  %2$s)\") " +
            "AND u='c'";

... 接着：

query = String.format(query, location.getLatitude(), location.getLongitude());
