前提须知
笔者公司的我的项目在微信端的功能定位为根底性能交易及服务,告诉用户交易揭示、交易流水等,而 APP 为次要的交易性能。之前是在多个页面有引流按钮跳转至 App,性能点比拟粗犷,间接 location.href = 利用宝链接。当初产品有需要,说要用微信提供的标签来唤起 App
需要点:
所有跳转至 App 下载页面的局部,改成
Demo 后行
遇事不决,官网文档。查看后与微信 JS-SDK 性能点很像,这里我不废话,间接跳过。依照官网 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);
测试胜利,demo 能跑通
组件试点
当初搞业务,以这个组件(Download)为试点开展,我要点击页面顶部的卡片(多个中央应用,抽离成 Download 组件),让其唤起 App,然而要判断其版本,如果版本过低,让其跳转至利用宝
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">立刻关上</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);
成果如下所示:
思路逻辑参考:wx-open-launch-weapp 款式问题,我也给它配上色彩,不便后续察看
测试同步,能点击卡片跳转,好,下一步,在所有须要点击跳转页面的中央退出相似这样的代码
<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,就能够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 组件也就能够洁净很多
...
const Download = () => {
...
return (
...
<div className="Download__btn">立刻关上</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
回到需要点,每个点击的中央都要弹出弹出框,点击 关上 App ,再唤起 App,这样的话,弹出框 + WxOpenLaunchApp 就能够联合成一个组件,放进去供页面调用,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="道歉,此性能需在雅美App中应用"
btnSubmitText={
<div style={{ position: 'relative' }}>
关上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:
接着在所有有跳转 App 的页面上用上这块逻辑即可
封装 HOOK
每个页面点击相似 下载App 按钮时,会弹出 OpenAppPopup,点击 关上App,须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,果决抽离成 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;
逻辑也很简略,在刚加载时判断它是否能够点击,能够点击,就设置 enableLaunchWeapp 为 true。应用办法也很简略
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
需要点里说:要在所在页面跳转至 App 绝对页面,文档上写的很显著,能够传参数 extinfo=”your-extinfo”,轻易写了个让客户端同当时测试先
未唤醒 App
我手机是 IOS 的,是能够唤起的,然而安卓共事调试的时候说,后盾运行时,能够唤起 App,然而没有切换动作;如果杀掉过程,就无奈唤起。而这问题,大概率是 SDK 配置的问题,共事看了半天没解决,扔给他 Android 接入指南 。我又看不懂 Android,只能看他了
如果测试胜利,能跳过去,那么就把本页链接当作 extinfo 传过来,他那边接管到 extinfo 后,做个映射表,跳转至本身的页面即可,所以 WxOpenLaunchApp 须要革新,多一个 extinfo 参数。。。
后记
因为咱们用的是 flutter,共事说,因为引入的第三方库不反对,所以跳不过来,所以这个性能要后置,等他搞定了我再做更新
错误处理
除了在 WxOpenLaunchApp 组件中退出监听 error,谬误就让它跳转至 App 外,还要做当微信或者零碎版本不反对微信标签时,须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) // 无奈应用凋谢标签的谬误起因,需回退兼容。仅无奈应用开发标签,JS-SDK其余性能不受影响
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
