【问题描述】：

我正在尝试使用 Yahoo!以摄氏度为单位的天气 API。

我在请求中添加了&u=c，但它仍在以华氏温度返回数据。

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

然后回应：

有什么想法吗？

【问题讨论】：

你解决过这个问题吗？

【参考方案1】：

迟到总比没有好...

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=?";

如果你把它分开，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 url 的末尾。

【讨论】：

u='c' 不适合我...它钢给我的结果是 F

对我来说是 u="c" 醒来，而不是 u='c'

【参考方案2】：

我用的是yql

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

它在摄氏度的结果中运行良好。我为该区域的真实 WOEID 更改了“LEXX0003”，它似乎有效。

【参考方案3】：

每当我必须以摄氏度调用我想要的温度时，我只使用一个简单的转换函数：

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

然后，我想在华氏温度和摄氏温度之间切换。如果您只想使用摄氏温度，那么从 Yahoo 调用摄氏 JSON 元素可能会更好。

【参考方案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"

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

我刚刚尝试时的这项工作

【参考方案5】：

只要这样做，确保它会起作用

在 YQL 查询末尾添加 --> and 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"
