我知道之前会问这类问题......但是我无法弄明白......我已经阅读了这个操作系统问题link1和link2
我正在开发一个天气预报应用程序，因为我正在使用yahoo weather api。
我正在使用此网址进行回复
String url = "https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid="+woeid+
" and u='c'&format=xml&env=store://datatables.org/alltableswithkeys";
url = url.replace(" ","%20");

作为回应......我没有在摄氏度中获得温度...请帮助我
答案 0 :(得分：1)
修改的
我在控制台上尝试了您的位置，如果您请求这些项目，您会在预测和当前条件下获得摄氏度。我试过了：
select item.forecast from weather.forecast where woeid = 2295402 and u='c'
以摄氏度返回了10天的预测。 URL将是
https://query.yahooapis.com/v1/public/yql?q=select%20item.forecast%20from%20weather.forecast%20where%20woeid%20%3D%202295402%20and%20u%3D'c'&format=xml&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys
将item.forecast更改为item.conditions会对当前条件执行相同操作。我再次尝试选择*并且它给出了华氏度错误。也许对这些项目使用单独的查询可以帮到你？
答案 1 :(得分：0)
似乎返回温度是华氏温度。
您可以使用以下公式将其转换为摄氏度：
C =（F-32）×5/9
