利用高德地图API实现实时天气

前言

闲来无事，利用摸鱼时间实现实时天气的小功能

目录

效果图

这里样式我就不做处理了，地图可以不用做展示，只需要拿到获取到天气的结果，结合自己的样式展示就可以了，未来天气可以结合echarts进行展示，页面效果更佳

实现

这里应用名称可以随便取（个人建议功能名称或者项目称）

3.获取 key 和密钥

4.获取当前城市定位

首先，先安装依赖

npm install @amap/amap-jsapi-loader --save

或者

pnpm add @amap/amap-jsapi-loader --save

页面使用时引入即可 import AMapLoader from "@amap/amap-jsapi-loader"

/**在index.html引入密钥,不添加会导致某些API调用不成功*/


<script type="text/javascript">window._AMapSecurityConfig = 

{securityJsCode: "安全密钥"}</script>

  /** 1.  调用AMapLoader.load方法，通过传入一个对象作为参数来指定加载地图时的配置信息。

   *  -   key: 申请好的Web端开发者Key，是必填项，用于授权您的应用程序使用高德地图API。

   *  -   version: 指定要加载的JSAPI版本，不指定时默认为1.4.15。

   *  -   plugins: 需要使用的插件列表，如比例尺、缩放控件等。

   */
function initMap() {
AMapLoader.load({
key: "申请好的Web端开发者Key", // 申请好的Web端开发者Key，首次调用 load 时必填
version: "2.0", // 指定要加载的 JSAPI 的版本，缺省时默认为 1.4.15
plugins: [
"AMap.ToolBar",
"AMap.Scale",
"AMap.HawkEye",
"AMap.MapType",
"AMap.Geolocation",
"AMap.Geocoder",
"AMap.Weather",
"AMap.CitySearch",
"AMap.InfoWindow",
"AMap.Marker",
"AMap.Pixel",

    ], // 需要使用的的插件列表，如比例尺'AMap.Scale'等

  })

    .then((AMap) => {

      map.value = new AMap.Map("container", {
//设置地图容器id
resizeEnable: true,
viewMode: "3D", //是否为3D地图模式
zoom: 10, //初始化地图级别
center: locationArr.value, //初始化地图中心点位置

      });

getGeolocation(AMap);
getCitySearch(AMap, map.value);

    })

    .catch((e) => {
console.log(e);

    });

}

// 浏览器定位
const getGeolocation = (AMap: any) => {
const geolocation = new AMap.Geolocation({
enableHighAccuracy: true, //是否使用高精度定位，默认:true
timeout: 1000, //超过10秒后停止定位，默认：5s
position: "RB", //定位按钮的停靠位置
offset: [10, 20], //定位按钮与设置的停靠位置的偏移量，默认：[10, 20]
zoomToAccuracy: true, //定位成功后是否自动调整地图视野到定位点

  });

  map.value.addControl(geolocation);

  geolocation.getCurrentPosition(function (status: string, result: any) {
if (status == "complete") {
onComplete(result);

    } else {
onError(result);

    }

  });

};

// IP定位获取当前城市信息
const getCitySearch = (AMap: any, map: any) => {
const citySearch = new AMap.CitySearch();

  citySearch.getLocalCity(function (

    status: string,

    result: {

      city: string;

      info: string;

    }
) {
if (status === "complete" && result.info === "OK") {
console.log(
"🚀 ~ file: map-container.vue:88 ~ getCitySearch ~ result:",

        result

      );
// 查询成功，result即为当前所在城市信息
getWeather(AMap, map, result.city);

    }

  });

};


onMounted(() => {
initMap();

});

5.通过定位获取城市名称、区域编码，查询目标城市/区域的实时天气状况

const getWeather = (AMap: any, map: any, city: string) => {
const weather = new AMap.Weather();

  weather.getLive(

    city,
function (

      err: any,

      data: {

        city: string;

        weather: string;

        temperature: string;

        windDirection: string;

        windPower: string;

        humidity: string;

        reportTime: string;

      }
) {
if (!err) {
const str = [];

        str.push("<h4 >实时天气" + "</h4><hr>");

        str.push("<p>城市/区：" + data.city + "</p>");

        str.push("<p>天气：" + data.weather + "</p>");

        str.push("<p>温度：" + data.temperature + "℃</p>");

        str.push("<p>风向：" + data.windDirection + "</p>");

        str.push("<p>风力：" + data.windPower + " 级</p>");

        str.push("<p>空气湿度：" + data.humidity + "</p>");

        str.push("<p>发布时间：" + data.reportTime + "</p>");
const marker = new AMap.Marker({
map: map,
position: map.getCenter(),

        });
const infoWin = new AMap.InfoWindow({
content:
'<div class="info" style="position:inherit;margin-bottom:0;background:#ffffff90;padding:10px">' +

            str.join("") +
'</div><div class="sharp"></div>',
isCustom: true,
offset: new AMap.Pixel(0, -37),

        });

        infoWin.open(map, marker.getPosition());

        marker.on("mouseover", function () {

          infoWin.open(map, marker.getPosition());

        });

      }

    }

  );

 }
