如何使用天气API来创建我的天气HTML页面

您必须查看API文档，它应该告诉您如何从服务请求数据。如果没有链接，我们无法帮助你。

这应该会让你对如何在PHP中使用JSON和api有一个大致的了解，但是如果你正在寻找一个简单的拉取机制来更新页面上的天气，你不需要那么重的东西:它不需要在服务器端。

我建议使用JavaScript，就像这样:

var req = new XMLHttpRequest();
var url = "yourURL"; //it is important that you read the API docs for this, because some APIs require you to use your API key in your request
req.open('GET', url, true);
req.onload = function (e) {
    if (req.readyState == 4 && req.status == 200) {
        if (req.status == 200) {
            var response = JSON.parse(req.responseText); //response is now an object containing all of the data that the API gives you; again, you'll have to look at the API docs to see how that information is formatted
            //update your page here using response data
            }
        }
    }
};
req.send(null);

无论哪种方式，您都将返回一个JSON对象，其格式如下:

var response = [

例如，你可以用

response[0].website;

您也可以使用纯XML，但JSON是发出API请求最流行的方式。
