Yahoo Weather Query by Latitude and Longitude

2019-03-10 04:31发布

问题:

I want to fetch some weather data via latitude and longitude using yahoo query. but it seems this query is not available now. the query is below:

select * from weather.forecast where woeid in (SELECT woeid FROM geo.placefinder WHERE text="{lat},{lon}" and gflags="R")

is this query is changed to new one or something? or it didn't exist anymore? last time I use this format was about 2 months ago and it worked well. but now it can't fetch any data. result from YQL console is as below:

{
 "error": {
  "lang": "en-US",
  "description": "Tenant 'query_yahooapis_com' access to 'Resource [tenantName=query_yahooapis_com, type=TABLE, name=geo.placefinder, locatorType=FILE, url=/home/y/share/manhattan/application/tenantBundles/yql_query_yahooapis_com_manhattan_v2/YQL-INF/restdefs/geo.placefinder.xml, useUrl=false]' is denied."
 }
}

I already make some research, including this post: How to get Yahoo's woeid by location?

Is that true that yahoo already terminate this latitude longitude query for fetching weather?

According to the latest reply to this answer, you should switch to the table geo.places and remove the gflags="R" part. I tried it in the YQL console and it seems to work:

select * from weather.forecast where woeid in (SELECT woeid FROM geo.places WHERE text="(latitude,longitude)")

This works for me(you should switch to the table geo.places(1)):

...

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

... and then:

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