前言
目前公司Vue H5项目,用webview打包成APP,现产品提出这样打包出来的app运行较慢,需要用uniapp方式(即使用HBuilder编辑器来打包H5)来打包,那需要的基座就不是安卓的基座而是uniapp的基座,而H5项目实现手机扫描功能就需要调用uniapp的基座的方法。
具体步骤
一、Uniapp Webview 源码
<template><view><web-view :webview-styles="webviewStyles" :src="src" @message="showMessage"></web-view></view></template><script>export default {data() {return {webviewStyles: {progress: {color: '#FF3333'}},src:'http://******/', // H5项目地址qrCodeWv: null}},onReady() {// #ifdef APP-PLUSlet currentWebview = this.$scope.$getAppWebview()setTimeout(() => {this.wv = currentWebview.children()[0]this.qrCodeWv = currentWebview.children()[0]this.wv.setStyle({scalable:true})},1000)// #endif},methods: {showMessage(event) {if(event.detail.data && event.detail.data.length >0){let dataInfo = event.detail.data[0]console.log(dataInfo)let type = dataInfo.typeif(type==='scan') {this.startScanCode()}}},startScanCode() {const self = this uni.scanCode({onlyFromCamera: false,scanType: ['qrCode'],success: function(res) {setTimeout(() => {const result = res.result.replace(/'/g,'"')self.qrCodeWv.evalJS(`appScanCodeResult('${result}')`)})},complete: function(args){console.log(args)}})}}}</script>
二、H5 Vue项目引入js
1、在public新建js文件夹uni.webview.1.5.4.js文件,uni.webview.js 最新版地址
https://gitee.com/dcloud/uni-app/raw/dev/dist/uni.webview.1.5.4.js
2、index.html 引入 public/js 下文件
<script src="<%= BASE_URL %>js/uni.webview.1.5.4.js"></script>
3、main.js 定义回调方法和对象
window.appScanCodeResult = function (val) { window.appScanCodeResultString = val window.dispatchEvent(new CustomEvent("scanCodeResult"))}
4、Vue扫码页面代码
created() { window.addEventListener("scanCodeResult", this.handleAppScanCode, false) },onBeforeDestroy() { window.removeEventListener("scanCodeResult", this.handleAppScanCode) },methods: { handleAppScanCode() { const result = window.appScanCodeResultString console.log('扫码返回值---result',result) }, // 点击扫码按钮 saoCode() { uni.postMessage({ data: { type: "scan" } }) }}
