vue 中使用腾讯地图（动态引用腾讯地图及使用签名验证）

在这里插入图片描述

在设置定位的时候使用腾讯地图选择地址
在 mounted中引入腾讯地图：
this.website.mapKey 为地图的 key

// 异步加载腾讯地图APIconst script = document.createElement('script');script.type = 'text/javascript';script.src = 'https://map.qq.com/api/js?v=2.exp&key='+this.website.mapKey+'&callback=init';document.body.appendChild(script);// 回调函数，初始化地图window.init = () => {this.initMap();this.$nextTick(()=>{if(this.map){//   // 监听中心点变化事件，更新marker的位置this.listener=qq.maps.event.addListener(this.map, 'dragend', ()=>this.centerChanged());}})};

在 destroyed 卸载

 destroyed(){let scripts = document.querySelectorAll('script');// 遍历所有找到的<script>元素并移除它们scripts.forEach((script)=> {let src=script.getAttribute('src');if(src&&src.indexOf('qq')>=0){script.parentNode.removeChild(script);}});qq.maps.event.removeListener(this.listener)},

弹框组件代码为：

以逆地址解析为例写法为：

import request from "@/axios";
//逆地址解析
export const getAddressByLat = (params) =>{return request.jsonp('/ws/geocoder/v1', {output: "jsonp",...params})
}

axios 调用 jsonp 方法

import axios from 'axios';
import {serialize} from '@/util/util';
import {Message} from 'element-ui';
axios.jsonp = function(url,data){if(!url) throw new Error('接口地址错误')function sortObjectByKeys(obj) {return Object.keys(obj).sort().reduce((sortedObj, key) => {sortedObj[key] = obj[key];return sortedObj;}, {});}const callback = 'CALLBACK' + Math.random().toString().substr(9,18)const time=Date.now();let newData=sortObjectByKeys({...data,callback,time});let sign=md5(`${url}?${serialize(newData)}YOUR_SK`);const JSONP = document.createElement('script')JSONP.setAttribute('type','text/javascript')const headEle = document.getElementsByTagName('head')[0];JSONP.src = `https://apis.map.qq.com${url}?${serialize(newData)}&sig=${sign}`;return new Promise( (resolve) => {window[callback] = r => {if(r.status!='0'){Message({message: r.message,type: 'warning'});}resolve(r)headEle.removeChild(JSONP)delete window[callback]}headEle.appendChild(JSONP)})
}
export default axios;
