android点击跳转页面(使用微信wx-open-launch-app标签实现微信网页打开App)

前提须知

笔者公司的项目在微信端的功能定位为基础功能交易及服务,通知用户交易提醒、交易流水等,而 APP 为主要的交易功能。之前是在多个页面有引流按钮跳转至 App,功能点比较粗暴,直接 location.href = 应用宝链接。现在产品有需求,说要用微信提供的标签来唤起 App

需求点:

所有跳转至 App 下载页面的部分,改成

需求点

Demo 先行

遇事不决,官网文档。查看后与微信 JS-SDK 功能点很像,这里我不废话,直接跳过。按照官网 demo,把示例写进业务代码中

import React, { useEffect, useRef } from 'react'; import { toDownloadApp, isWechat, getWeixinVersion } from 'utils'; const Download = () => { const wxRef = useRef(null) useEffect(() => { if (wxRef.current) { // @ts-ignore wxRef.current?.addEventListener('launch', function (e: any) { console.log('success'); }); // @ts-ignore wxRef.current.addEventListener('error', function (e) { console.log('fail', e.detail); toDownloadApp() }); } }, []) const onHandleClick = () => { toDownloadApp() } return ( <div className="Download" onClick={onHandleClick}> {/* @ts-ignore */} <wx-open-launch-app ref={wxRef} appid="XXXX" > <script type='text/wxtag-template'> <button>App内查看</button> </script> {/* @ts-ignore */} </wx-open-launch-app> </div> ) } export default React.memo(Download);

测试成功,demo 能跑通

组件试点

现在搞业务,以这个组件(Download)为试点展开,我要点击页面顶部的卡片(多个地方使用,抽离成 Download 组件),让其唤起 App,但是要判断其版本,如果版本过低,让其跳转至应用宝

import React, { useState, useEffect, useRef } from 'react'; import LogoImg from '@/assets/images/logo.png'; import { toDownloadApp, isWechat, getWeixinVersion } from 'utils'; const Download = () => { const wxRef = useRef(null) const [enableLaunchWeapp, setEnableLaunchWeapp] = useState(false); useEffect(() => { const wxVersion = isWechat() && getWeixinVersion() || '' if (wxVersion) { let v = wxVersion.split('.') if (Number(v[0]) >= 7) { if (Number(v[1]) >= 0) { if (Number(v[2]) >= 12) { setEnableLaunchWeapp(true) } } } } if (wxRef.current) { // @ts-ignore wxRef.current?.addEventListener('launch', function (e: any) { console.log('success'); }); // @ts-ignore wxRef.current.addEventListener('error', function (e) { console.log('fail', e.detail); toDownloadApp() }); } }, []) const onHandleClick = () => { if (!enableLaunchWeapp) { toDownloadApp() } } return ( <div className="Download" onClick={onHandleClick}> <div className="Download__logo"> <img src={LogoImg} alt="logo" /> </div> <div className="Download__content"> <div className="Download__content-title">雅美App</div> <div className="Download__content-desc">长泽雅美服务专区</div> </div> {/* <div>1</div> */} <div className="Download__btn">立即打开</div> {/* @ts-ignore */} <wx-open-launch-app ref={wxRef} appid="XXXXX" style={{ position: 'fixed', top: 0, left: 0, width: '100%', height: '60px', opacity: 0.3, background: 'blue' }} > <script type='text/wxtag-template'> <div style={{ position: 'fixed', top: 0, left: 0, width: '90%', height: '100%', opacity: 0.3, background: 'red' }} /> </script> {/* @ts-ignore */} </wx-open-launch-app> </div> ) } export default React.memo(Download);

效果如下所示:

点击范围

思路逻辑参考:wx-open-launch-weapp 样式问题,我也给它配上颜色,方便后续观察

测试同步,能点击卡片跳转,好,下一步,在所有需要点击跳转页面的地方加入类似这样的代码

<wx-open-launch-app ref={wxRef} appid="XXXX" style={{ position: 'fixed', top: 0, left: 0, width: '100%', height: '60px', opacity: 0.3, background: 'blue' }} > <script type='text/wxtag-template'> <div style={{ position: 'fixed', top: 0, left: 0, width: '90%', height: '100%', opacity: 0.3, background: 'red' }} /> </script> {/* @ts-ignore */} </wx-open-launch-app>封装组件 WxOpenLaunchApp

如果是这样,就可以将其封装成一个组件了,起个名吧: WxOpenLaunchApp

将唤起 App 的内容包装成一个组件,暴雷 children 和 style 两个 props,代码如下:

import React, { useEffect, useRef, forwardRef } from 'react'; import { toDownloadApp } from 'utils'; export interface WxOpenLaunchAppProps { children: React.ReactNode; style?: React.CSSProperties; } const WxOpenLaunchApp: React.FC<WxOpenLaunchAppProps> = props => { const { style, children } = props; const wxRef = useRef(null) useEffect(() => { if (wxRef.current) { // @ts-ignore wxRef.current?.addEventListener('launch', function (e: any) { console.log('success'); }); // @ts-ignore wxRef.current.addEventListener('error', function (e) { console.log('fail', e.detail); toDownloadApp() }); } }, []) return ( <div className="wx-open-launch-app"> {/* @ts-ignore */} <wx-open-launch-app ref={wxRef} appid="XXXX" style={style} > <script type='text/wxtag-template'> {children} </script> {/* @ts-ignore */} </wx-open-launch-app> </div> ) } export default React.memo(WxOpenLaunchApp);

那么 Download 组件也就可以干净很多

... const Download = () => { ... return ( ... <div className="Download__btn">立即打开</div> {/* @ts-ignore */} <WxOpenLaunchApp style={{ position: 'fixed', top: 0, left: 0, width: '100%', height: '60px', opacity: 0.3, background: 'blue' }}> <div style={{ position: 'fixed', top: 0, left: 0, width: '100%', height: '100%', opacity: 0.3, background: 'red' }} /> </WxOpenLaunchApp> ... ) } ...业务组件 OpenAppPopup

回到需求点,每个点击的地方都要弹出弹出框,点击 打开 App ,再唤起 App,这样的话,弹出框 WxOpenLaunchApp 就可以结合成一个组件,放出来供页面调用,名字就叫 OpenAppPopup ,代码如下:

import React, { FC } from 'react'; import { Popup, WxOpenLaunchApp, Toast } from 'components'; // 此乃公司自研组件库 export interface OpenAppPopupProps { show: boolean; onCancel: () => void; onSubmit: () => void; } const OpenAppPopup: FC<OpenAppPopupProps> = (props) => { const { show, onCancel, onSubmit } = props; return ( <Popup.Group show={show}> <Popup.Confirm title="抱歉,此功能需在雅美App中使用" btnSubmitText={ <div style={{ position: 'relative' }}> 打开App <WxOpenLaunchApp style={{ position: 'absolute', top: 0, left: 0, width: '100%', height: '100%', opacity: 0.3, background: 'blue' }}> <div style={{ position: 'absolute', top: 0, left: 0, width: '100%', height: '100%', opacity: 0.6, background: 'red' }} /> </WxOpenLaunchApp> </div> } onCancel={onCancel} onSubmit={onSubmit} /> </Popup.Group> ) } export default React.memo(OpenAppPopup);

示意图如下:

OpenAppPopup

接着在所有有跳转 App 的页面上用上这块逻辑即可

封装 HOOK

每个页面点击类似 下载App 按钮时,会弹出 OpenAppPopup,点击 打开App,需要判断你的微信版本,是否达到 7.0.12,如果每个页面都要加上这段

const wxVersion = (isWechat() && getWeixinVersion()) || '' if (wxVersion) { let v = wxVersion.split('.') if (Number(v[0]) >= 7) { if (Number(v[1]) >= 0) { if (Number(v[2]) >= 12) { setEnableLaunchWeapp(true) } } } }

真的太恶心了,果断抽离成 hook。代码如下:

import { useState, useEffect } from 'react'; import { isWechat, getWeixinVersion } from 'utils'; const useEnableLaunchWeapp = () => { const [enableLaunchWeapp, setEnableLaunchWeapp] = useState(false); useEffect(() => { const wxVersion = isWechat() && getWeixinVersion() || '' if (wxVersion) { let v = wxVersion.split('.') if (Number(v[0]) >= 7) { if (Number(v[1]) >= 0) { if (Number(v[2]) >= 12) { setEnableLaunchWeapp(true) } } } } }, []) return enableLaunchWeapp } export default useEnableLaunchWeapp;

逻辑也很简单,在刚加载时判断它是否可以点击,可以点击,就设置 enableLaunchWeapp 为 true。使用方法也很简单

import React, { useState, useEffect } from 'react'; import { Dispatch, History } from 'umi'; import { OpenAppPopup } from 'components'; import { useEnableLaunchWeapp } from 'hooks'; import { toDownloadApp } from 'utils'; interface KVProps { history: History; } const KV: React.FC<KVProps> = (props) => { const { history } = props; const [isShow, setIsShow] = useState(false); const enableLaunchWeapp = useEnableLaunchWeapp(); const onHandleClickToBuy = () => { setIsShow(true); }; const onHandleClickToSubmit = () => { if (!enableLaunchWeapp) { toDownloadApp() } } return ( <div className="KV" style={{ background: kvBgColor }}> <div className="KV__content"> <img src={img} alt="" /> </div> <OpenAppPopup show={isShow} onCancel={() => { setIsShow(false); }} onSubmit={onHandleClickToSubmit} /> </div> ); }; export default React.memo(KV);与 App 交互

需求点里说:要在所在页面跳转至 App 相对页面,文档上写的很明显,可以传参数 extinfo="your-extinfo",随便写了个让客户端同事先测试先

未唤醒 App

我手机是 IOS 的,是可以唤起的,但是安卓同事调试的时候说,后台运行时,可以唤起 App,但是没有切换动作;如果杀掉进程,就无法唤起。而这问题,大概率是 SDK 配置的问题,同事看了半天没解决,扔给他 Android 接入指南 。我又看不懂 Android,只能看他了

如果测试成功,能跳过去,那么就把本页链接当作 extinfo 传过去,他那边接收到 extinfo 后,做个映射表,跳转至自身的页面即可,所以 WxOpenLaunchApp 需要改造,多一个 extinfo 参数。。。

后记

因为我们用的是 flutter,同事说,因为引入的第三方库不支持,所以跳不过去,所以这个功能要后置,等他搞定了我再做更新

错误处理

除了在 WxOpenLaunchApp 组件中加入监听 error,错误就让它跳转至 App 外,还要做当微信或者系统版本不支持微信标签时,需要监听并进行回退兼容,代码如下:

document.addEventListener('WeixinOpenTagsError', function (e: any) { console.error(e.detail.errMsg) // 无法使用开放标签的错误原因,需回退兼容。仅无法使用开发标签,JS-SDK其他功能不受影响 toDownloadApp() })总结

又复用就抽离成组件

必须要上生产环境,所以最好是有个预生产环境
