uni-app 使用高德地图部分内容

1.申请key
高德开放平台 | 高德地图API注册申请，在管理应用里添加应用，然后根据需求申请高德地图的Key

2、新建一个动态加载高德地图的js。
 

export default function loadMap (key, plugins, v = '1.4.14') {
  return new Promise(function (resolve, reject) {
    if (typeof AMap !== 'undefined') {
      // eslint-disable-next-line no-undef
      resolve(AMap)
      return true
    }
    window.onCallback = function () {
      // eslint-disable-next-line no-undef
      resolve(AMap)
    }
    let script = document.createElement('script')
    // script.type = 'text/javascript'
    script.src = `https://webapi.amap.com/maps?v=${v}&key=${key}&plugin=${plugins}&callback=onCallback`
    script.onerror = reject
    document.head.appendChild(script)
  })
}

3、获取定位
import Gaode_loadMap from '../../common/js/gaode_loadMap'; //引入加载地图的js

Gaode_loadMap('webjs_key', ['AMap.Geolocation'], '1.4.14')
					.then(AMap => {
						var map = AMap.plugin('AMap.Geolocation', function() {
							var geolocation = new AMap.Geolocation({
								// enableHighAccuracy: true,// 是否使用高精度定位，默认：true
								// 设置定位超时时间，默认：无穷大
								timeout: 6000
							});
							geolocation.getCurrentPosition();
							AMap.event.addListener(geolocation, 'complete', onComplete);
							AMap.event.addListener(geolocation, 'error', onError);

							function onComplete(data) {
								// console.log('gen geo data===' + JSON.stringify(data));
								state.gd_loction = data.position
								console.log('state.gd_loction===' + state.gd_loction);
								let geo = state.gd_loction.toString().split(',')
								state.lnt = geo[0]
								state.lat = geo[1]
								uni.hideLoading();
							}

							function onError(data) {
								console.log(data);
								uni.showModal({
									title: '',
									content: '未获取到定位请前往选择',
									showCancel: false,
									cancelText: '取消',
									confirmText: '确定',
									success: res => {
										if (res.confirm) {
											uni.hideLoading()
											toChooseAdr()
										}
									},
									fail: () => {},
									complete: () => {}
								});
								// 定位出错
							}
						});

					})
					.catch(() => {
						console.log('地图加载失败！');
					});

 4、根据关键字获得地址
参考文档 搜索POI-API文档-开发指南-Web服务 API | 高德地图API

uni.request({
                    url: 'https://restapi.amap.com/v3/assistant/inputtips?output=JSON&city=010&type=poi&keywords=关键字' + '&key=web服务Key',
                    method: 'GET',
                    data: {},
                    success: res => {
                        state.addressList = []
                        let list = res.data.tips
                        //有时候会返回空名称
                        state.addressList = list.filter(item => item.address.length > 0) 
                    },
                    fail: () => {},
                    complete: () => {}
                });

5、小程序获取定位
相关下载-微信小程序插件 | 高德地图API 下载高德地图提供的插件
import amapFile from '@/utils/amap-wx.130.js' //引入
 

letmyAmapFun = new amapFile.AMapWX({
					key: 'key'
				})
				let that = this
				myAmapFun.getRegeo({
					success: data => {
						//成功回调
						console.log(data)						
					},
					fail: info => {
						//失败回调
						console.log(info)
					}
				})
