Question

它是怎么回事我试图改变这个我从华氏教程到摄氏温度建立的网络应用程序可能非常容易但我在编码方面是一个菜鸟所以对我很好:)。

我搜索了高低，我遇到的一些网站说改变了API网址中的查询，这对他们起了作用。这取自API文档本身（可以选择通过使用查询参数修改API请求。它将响应以下内容）通过添加？units = si 对于url查询它应该工作，但它对我不起作用我已经尝试过这么多不同的方式，所以我很丢失，说实话，任何帮助都会很好，试着想出来，谢谢你。< / p>

Answer 1

没有必要使用任何API查询或键来解决此问题，您只需使用数学方程式将华氏温度转换为cesius：

fahrenheit = cesius * 1.8 + 32

因此，在您的success:函数中，只需进行转换：

success: function(json) {
    json.currently.temperature = json.currently.temperature * 1.8 + 32;
    ...
}

华氏度到摄氏度
