流程如下：

1、安装百度地图

先在根目录上（或者public中）的index.html文件的body标签中加入

<script  src="https://api.map.baidu.com/api?v=3.0&ak=你在百度地图申请的Ak"></script>

然后，新建一个bdmap.js文件，放入以下内容，并且在你要使用的页面中引入，

export default {
    init: function () {
        const AK = "EAG3waLsHfeWew8ZjxlvQgvxuqXY5moB"; //AK
        const BMap_URL =
            "https://api.map.baidu.com/api?v=2.0&ak=" +
            AK +
            "&s=1&callback=onBMapCallback";
        return new Promise((resolve, reject) => {
            // 如果已加载直接返回
            if (typeof BMap !== "undefined") {
                resolve(BMap);
                return true;
            }
            // 百度地图异步加载回调处理
            window.onBMapCallback = function () {
                resolve(BMap);
            };

            // 插入script脚本
            let scriptNode = document.createElement("script");
            // scriptNode.setAttribute(type, 'text/javascript');
            scriptNode.setAttribute("src", BMap_URL);
            document.body.appendChild(scriptNode);
        });
    },
};

2、结合浏览器获取你所在城市位置

3、通过位置获取城市ID

4、通过城市ID获取城市天气状况

<template>
  <div></div>
</template>

<script>
import { ref, reactive, onMounted } from "vue";
import myBMap from "./bmap.js"; // 引入刚才创建的bmap.js文件
import axios from "axios";
export default {
  //props: {},
  components: {},
  setup() {
    let weather = ref(""); // 天气
    let temperature = ref(""); // 温度

    // 结合浏览器获取城市位置(我只需要获取省和市,具体看个人需求)
    const getCity = () => {
      // const BMap = (window as any).BMapGL;
      myBMap.init().then((BMap) => {
        let myCity = new BMap.LocalCity();
        myCity.get(
          (result) => {
            let geoc = new BMap.Geocoder();
            geoc.getLocation(result.center, (res) => {
              // 位置信息
              console.log("位置", res.addressComponents);

              getLocationId(
                res.addressComponents.province,
                res.addressComponents.city
              );
            });
          },
          { enableHighAccuracy: true }
        );
      });
    };

    // 获取城市id
    const getLocationId = (province, city) => {
      axios({
        method: "get",
        url:
          "https://geoapi.qweather.com/v2/city/lookup?key=56a14978f76747a8897384f7bef56c20&adm=" +
          province +
          "&location=" +
          city,
      }).then((res) => {
        getWeather(res.data.location[0].id);
        console.log(res.data.location[0]);
      });
    };

    // 获取天气
    const getWeather = (id) => {
      axios({
        method: "get",
        url:
          "https://devapi.qweather.com/v7/weather/now?key=56a14978f76747a8897384f7bef56c20&location=" +
          id,
      }).then((res) => {
        temperature.value = res.data.now.temp;
        weather.value = res.data.now.text;
        console.log(res.data, 1213);
      });
    };

    onMounted(async () => {
      getCity(); // 获取城市
      // var result = await axios.get(
      //   "http://wthrcdn.etouch.cn/weather_mini?city=" + "杭州"
      // );
      // console.log(result.data.data.forecast);
    });

    return {
      getWeather,
      getLocationId,
      getCity,
      weather,
      temperature,
    };
  },
};
</script>

<style scoped lang="less"></style>
