首先需要在 Vue.js 项目中安装百度地图 JavaScript API SDK，并获取相应的密钥（ak）。然后，可以按照以下步骤使用百度地图的天气查询功能并使用 Axios 进行请求：
官网文档：https://lbsyun.baidu.com/faq/api?title=webapi/weather/base
- 在
index.html 中添加百度地图 JavaScript API SDK 的引用：
<script type="text/javascript" src="https://api.map.baidu.com/api?v=3.0&ak=YOUR_AK"></script>
请将 YOUR_AK 替换为你自己在百度地图开放平台申请的密钥。
- 在需要使用天气查询功能的组件中，用以下代码创建一个名为
map 的百度地图实例：
created() {
const map = new BMap.Map("map-container");
this.map = map;
}
其中 "map-container" 是容器元素的 ID，可以根据需要替换成其他值。同时，需要在 data 属性中添加 map 字段，以便在后续使用中保持对该实例的引用。
- 创建一个
getWeather 方法，用于向百度地图天气 API 发送请求并处理返回结果：
methods: {
async getWeather() {
try {
const res = await axios.get(
"https://api.map.baidu.com/weather/v1/?district_id=110000&data_type=all&ak=YOUR_AK"
);
// 处理返回结果
} catch (error) {
console.error(error);
}
}
}
请将 YOUR_AK 替换为你自己在百度地图开放平台申请的密钥。此处使用了 Axios 库发送 GET 请求，并将返回结果存储在 res 变量中。
- 在组件模板中，添加一个按钮来触发
getWeather 方法：
<button @click="getWeather">查询天气</button>

这样，在用户点击按钮时就会向百度地图天气 API 发送请求并处理结果。
注意：以上代码仅为示例，实际项目中可能需要根据实际情况进行修改和调整。
我们更多的是让后端在服务器进行请求，然后把数据返回给前端，这样可以减少跨域和代理的麻烦！
