返回雅虎在摄氏天气API数据，使用YQL

Question

我试图让雅虎天气API，气温摄氏度。

我在请求加入&u=c，但它仍然在华氏返回数据。

这是我使用的网址：

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

和响应：

{"query":{"count":1,"created":"2014-01-13T13:06:43Z","lang":"en-US","results":{"channel":{"item":{"title":"Conditions for Beirut, LE at 1:59 pm EET","lat":"33.82","long":"35.48","link":"http://us.rd.yahoo.com/dailynews/rss/weather/Beirut__LE/*http://weather.yahoo.com/forecast/LEXX0003_f.html","pubDate":"Mon, 13 Jan 2014 1:59 pm EET","condition":{"code":"30","date":"Mon, 13 Jan 2014 1:59 pm EET","temp":"64","text":"Partly Cloudy"},"description":"\n<img src=\"http://l.yimg.com/a/i/us/we/52/30.gif\"/><br />\n<b>Current Conditions:</b><br />\nPartly Cloudy, 64 F<BR />\n<BR /><b>Forecast:</b><BR />\nMon - Partly Cloudy.

有任何想法吗？

Answer 1

迟到总比不到好...

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=?";

它很容易，如果你打破它读取。你我们非常接近，只是需要将U = C作为查询的一部分，而不是在网址的结尾。

Answer 2

我用YQL

select item from weather.forecast where woeid=22724447 and u='c'

并在摄氏结果运行良好。我改变了“LEXX0003”该区域的实际WOEID，似乎已经奏效。

Answer 3

每当我不得不打电话给我在想摄氏度的温度下我只是用一个简单的转换功能：

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

再说，我想华氏度和摄氏度之间切换。打电话只是从雅虎摄氏JSON元素，如果你想要使用的是摄氏度可能更好。

Answer 4

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"

终点：

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

这项工作时，我尝试刚才

Answer 5

只是这样做，可以肯定它会工作

在YQL查询的末尾> {且u =“C”} - 添加此

例如：

YQL查询

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