Vue如何写一个好看的天气组件

给大家分享一下我写的网站日期组件

主要是使用了和风天气的api，首先新建一个noAuthAxios.js 用来存放api, 确保不会被其他属性影响。

//天气api
import axios from 'axios'

const noAuthAxios = axios.create({
    baseURL: 'https://devapi.qweather.com', // 可设置第三方API基础路径
    timeout: 8000
})

export default noAuthAxios

根据和风天气的图标说明，天气状况分为白天和夜晚，每种天气状况都有对应的图标代码。以下是常见的天气状况及其图标分配：

vue组件代码具体如下：

模板部分

• 根据 weatherIcon 的值动态渲染对应的天气图标（sunny、cloudy、snowy、stormy、supermoon）。
• 显示加载状态或错误信息。

​JS部分

• temperature：从 weatherData 中提取温度。
• weatherStatus：从 weatherData 中提取天气描述。
• weatherIcon：根据天气描述和时间（夜晚时强制显示 supermoon）返回对应的图标类型。
• isNight：判断当前时间是否为夜晚（18:00 到 06:00）。
• fetchWeather：调用 API 获取天气数据并更新 weatherData。
