uniapp app和微信小程序使用腾讯地图定位

admin • 2021-11-30 21:31 • 移动开发

1. 首先注册个腾讯地图定位的key 链接https://lbs.qq.com/dev/console/key/add2. 在官网下载好 sdk 保存到你项目里面

3.使用sdk

import QQMapWX from "./wxsdk/qqmap-wx-jssdk.min.js";
import { newModal } from './new-modal.js'
 let getLocation;
 
 // #ifdef MP-WEIXIN
getLocation = () => {
   return new Promise((resolve, reject) => {
     // 获取授权信息
     uni.getSetting({
       success: res => {
         if (res.authSetting && res.authSetting.hasOwnProperty("scope.userLocation")) {
           if (res.authSetting["scope.userLocation"]) {
             getCityInfo();
           } else {
             uni.showModal({
               title: "提示",
               content: "请重新授权获取你的地理位置，否则部分功能将无法使用",
               success: (res) => {
                 if (res.confirm) {
                   uni.openSetting({
                     success: () => getCityInfo()
                   });
                 } else {
                   reject("请授权获取你的地理位置，否则部分功能将无法使用！");
                 }
               },
             });
           }
         } else {
           getCityInfo();
         }
       }
     });
  
     // 获取地理位置信息
     const getCityInfo = () => {
       // 腾讯地图Api
 	  console.log("locaiton getting")
       const qqmapsdk = new QQMapWX({ key: "你的key" });
       // 授权
       uni.authorize({
         scope: "scope.userLocation",
         success: () => {
           uni.getLocation({
             type: "gcj02", //  wgs84: 返回GPS坐标，gcj02: 返回国测局坐标
             success: res => {
               const {latitude, longitude} = res;
               const location = {latitude, longitude};
 			  console.log(location)
               qqmapsdk.reverseGeocoder({
                 location,
                 success: res => resolve(res.result),
 				fail: err => {
 					console.log(err)
 				}
               });
             }
           });
         },
         fail: () => reject("请授权获取你的位置，否则部分功能将无法使用！"),
       });
     };
   });
 };
 // #endif
 
 // #ifdef APP-PLUS
import {gotoAppPermissionSetting, checkSystemEnableLocation} from './permission.js'
getLocation = () => {
 	const qqmapsdk = new QQMapWX({
 		key: "你的key"
 	});
	return new Promise((resolve, reject) => {
		uni.getLocation({
			type: "gcj02", //  wgs84: 返回GPS坐标，gcj02: 返回国测局坐标
			success: res => {
				const {
					latitude,
					longitude
				} = res;
				const location = {
					latitude,
					longitude
				};
				qqmapsdk.reverseGeocoder({
					location,
					success: res => {
						resolve(res.result)
					},
					fail: err => {
						console.log(err)
					}
				});
			},
			fail(err) {
				const res = checkSystemEnableLocation()
				if(!res) {
					newModal({
						title: "设备定位未开启",
						content: "是否去开启？",
						success(res) {
							if(res.confirm) {
								gotoAppPermissionSetting()
							}
						}
					})
				}
			}
		})
	})
 };
 
 // #endif
 export default getLocation;

newModal 只是一个美化的 uni.showModal 可以以此代替

对这个感兴趣的以下是它的封装

export const newModal = function(options) {

getLocation 使用

import getLocation from '../../../utils/getLocation.js'
getl() {
	const self = this
	getLocation().then(res => {
		self.address = res.address
	})
}
