uniapp开发app使用谷歌地图(ios跟安卓)

admin2024-04-03  0

前提条件:

谷歌地图需要翻墙,否则无法加载

谷歌地图说明

  • 设置地图语言
<script async
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&language=ja&callback=initMap">
</script>

第一种方法(web-view):

web-view 是一个 web 浏览器组件,可以用来承载网页的容器,会自动铺满整个页面(nvue 使用需要手动指定宽高),一般都会用nvue,否则默认占满页面

  • 展示目录结构:

uniapp开发app使用谷歌地图(ios跟安卓),第1张

index.nvue

<template>
	<view>
		<view style="height: 100rpx;">222222222</view>
		<view class="" v-if="isShow">
			<web-view style="background-color: #fafafa;" ref="webview" :style="{ height: statusBarHeight + 'px'}"
				@onPostMessage="getMessage" :src="webUrl"></web-view>
		</view>
	</view>
</template>

<script>
	/**
	 * 
	 * 请看这里 
	 * source :来源 根据上个界面传来的type值 实现不同的功能  
	 * 
	 * */
	import Vue from 'vue';
	export default {
		data() {
			return {
				statusBarHeight: 500, //可视屏幕的高度
				webUrl: '',
				isShow: false,
				lat:'',
				lng:'' ,
				source: "",
			};
		},
		onLoad(e) {
			console.log(e.type)
			this.source = e.type;
			// #ifdef APP-PLUS
			this.getlocetion();
			// #endif
		},
		methods: {
			getlocetion() {
				const self = this;
				self.lat = '39.906217';
				self.lng = '116.3912757';
				self.webUrl = '/hybrid/html/maps/index' + self.source + '.html?lat=' + self.lat +
					'&lng=' +
					self.lng;
				self.isShow = true
			}
		}
	};

  • <script type="text/javascript" src="https://js.cdn.aliyun.dcloud.net.cn/dev/uni-app/uni.webview.1.5.2.js"></script>是什么

uni.webview.1.5.2.js 这个 JavaScript 文件为开发者提供了在 Uni-app 中使用 Webview 组件的丰富功能和接口,方便开发者在应用中集成和控制 web 页面

  • <link href="http://fonts.googleapis.com/css?family=Roboto:300" rel="stylesheet" type="text/css"> 是什么

在网页中引入 Google Fonts 中的 Roboto 字体。Google Fonts 提供了大量免费的网页字体供开发者使用

上面代码就可以生成一个谷歌地图示例了

第二种方法(render.js)

renderjs是一个运行在视图层的js。它比WXS更加强大。它只支持app-vue和web;

在视图层操作dom,运行 for web 的 js库

googleMap.vue

app繁体语言加载地图,绘制marker,绘制轨迹

遇到的问题

  • manifest.json中不用勾选map模块,否则google地图打包时会模块冲突,导致打包失败

例如报错日志:
