## 背景 ##

H5在微信里打开，然后直接唤起APP,为了解决deeplink 在安卓里不能直接唤起APP的问题

## 开发 ##

### 前置接口请求 ###

### 封装组件 ###

<template>
        
        <div v-if="isShow" id="wxOpenInAPPVui" class="wexin-launch-btn" >
            <wx-open-launch-app :id="id" style="width: 100%; height: 100%; display: block;" :appid="appid" :extinfo="getExtinfo" >
                <script type="text/wxtag-template"> <style>.btn { width:100%;height:65px;background: #fff}</style> <button class="btn">App内查看</button> </script>
            </wx-open-launch-app>
        </div>
    </template>
    <script> import Vue from 'vue'; // 忽略自定义元素标签抛出的报错 Vue.config.ignoredElements = [ 'wx-open-launch-app' ]; let idIndex = 0; export default { name: 'my-open-label', data () { idIndex++; return { id: 'wxopenLanchAppId' + idIndex, appid: '', /* 所需跳转的AppID */ isShow: false }; }, mounted () { this.init(); }, props: { href: { type: String, default: '' } }, computed: { /* eslint-disable vue/no-side-effects-in-computed-properties */ // 跳转所需额外信息 getExtinfo () { if (this.href.length === 0) { this.isShow = false; return ''; } else { const reg = new RegExp('[?&]json=([^#]+)'); const query = this.href.match(reg); const urlArr = query ? query[1] : null; if (urlArr) { try { const json = JSON.parse(urlArr); // eslint-disable-next-line quotes return `json={}`; /* 这里要跟客户端对接，客户端需要的参数 */ } catch (err) { console.log(err); this.isShow = false; return ''; } } else { this.isShow = false; return ''; } } } /* eslint-enable vue/no-side-effects-in-computed-properties */ }, methods: { init () { // 判断微信打开并且是安卓 if (/micromessenger/i.test(navigator.userAgent) && /Android/i.test(navigator.userAgent)) { this.isShow = true; } this.$nextTick(() => { if (this.isShow) { const _this = this; const btn = document.getElementById(this.id); if (!btn) { return; } btn.addEventListener('error', function () { window.location.href = _this.href; }); } }); } } }; </script>
    <style lang="scss" scoped> .wexin-launch-btn { position: absolute; left: 0; top: 0; width: 100%; height: 100%; opacity: 0; overflow: hidden; z-index: 1; } </style>

### 使用组件 ###

<template>
        <div>
            <my-open-label :href="deeplink"></my-open-label>
        </div>
    </template>
    <script> import WXOpenApp from 'WXOpenApp.js' export default { mounted () { const wx = WXOpenApp.getInstance(); wx.init(); } } </script>
