返回Yahoo!使用YQL以Celsius为天气API数据

我想要雅虎!天气API,温度为摄氏度。

我在请求中添加了&u=c,但它仍然以华氏度返回数据。

这是我正在使用的网址:

  

http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location=%22LEXX0003%22&format=json&u=c

有什么想法吗?

迟到总比不上......

var locationQuery = escape("select item from weather.forecast where woeid in (select woeid from geo.places where text='GB-LND') and u='c'"),
    locationUrl = "http://query.yahooapis.com/v1/public/yql?q=" + locationQuery + "&format=json&callback=?";

如果你分手,它会更容易阅读。你我们非常接近,只需要u = c作为查询的一部分,而不是在网址的末尾。

我使用了yql

maxlength

它在Celsius中的效果很好。我将“LEXX0003”更改为该区域的真实WOEID,似乎已经有效。

答案 2 :(得分:1)

每当我必须在Celsius中调用我想要的温度时,我只使用了一个简单的转换函数:

function FtoC(temp) {return Math.round((temp - 32) / (9 / 5));}

然后,我想在华氏和摄氏之间切换。如果您想要使用的只是Celsius,那么从Yahoo调用Celsius JSON元素可能会更好。

答案 3 :(得分:1)

你可以试试这个:

YQL查询:

select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="jiangmen,cn") and u="c"

端点:

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%22jiangmen%2Ccn%22)%20and%20u%3D%22c%22&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

刚刚尝试时的这项工作

答案 4 :(得分:-1)

只需执行此操作,确保它可以工作

在YQL查询末尾添加-> {和u =“ c” }

例如:

YQL查询

select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="greenland") and u="c"
