uni-app 是一个使用 Vue.js (opens new window)开发所有前端应用的框架,开发者编写一套代码,可发布到iOS、Android、Web(响应式)、以及各种小程序(微信/支付宝/百度/头条/飞书/QQ/快手/钉钉/淘宝)、快应用等多个平台。
全局安装vue-cli
npm install -g @vue/cli@4
使用Vue3/Vite版
npx degit dcloudio/uni-preset-vue#vite my-vue3-project
.eslintrc.js
module.exports = { root: true, env: { node: true }, extends: [ 'plugin:vue/vue3-essential', '@vue/standard' ], parserOptions: { parser: 'babel-eslint' }, rules: { 'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off', 'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off', //关闭组件命名规则 "vue/multi-word-component-names": "off", } }
https://www.quanzhan.co/luch-request
安装luch-request
npm i -S luch-request
根目录创建vue.config.js
module.exports = {
transpileDependencies: ['luch-request']
}
使用
import Request from 'luch-request'
// 将实例化当axios用就行
export const axios = new Request()
从iconfont下载压缩包到本地,解压后保留iconfont.css,修改iconfont.css中地址,然后地址前加上https://at.alicdn.com
@font-face {
font-family: 'iconfont';
/* Project id 2667731 */
src: url('https://at.alicdn.com/t/font_2667731_zq18s4xyfkej.woff2?t=1649751472791') format('woff2'),
url('https://at.alicdn.com/t/font_2667731_zq18s4xykfej.woff?t=1649751472791') format('woff'),
url('https://at.alicdn.com/t/font_2667731_zq18s4xyfkej.ttf?t=1649751472791') format('truetype');
}
将iconfont.css
引入到App.vue中,便可以使用iconfont了
@import "@/styles/iconfont.css";
因为使用eslint,直接使用uni的话会报lint错误,我们不妨从一个文件出口导出uni,那样还能二次拦截一次
/src/utils/uni.js
// eslint-disable-next-line
const uniGlobal = uni || window.uni
// 可以在uniGlobal复写属性
uniGlobal.log = function () {
console.log(...arguments)
}
export default uniGlobal
在vue文件中使用
import uni from '@/utils/uni'
export default {
mounted() {
uni.log('---uni console')
}
}
比如封装的showConfirm
,每个页面都需要,如果每个页面都要在template
中引入一次会很麻烦,可以使用slot
来解决这个痛点
/src/components/RootLayout.vue
<template>
<div>
<Confirm />
<slot></slot>
</div>
</template>
<script>
// AAA
// BBB
import Confirm from '@/components/Confirm'
export default {
components: { Confirm }
}
</script>
就可以将AAA
、BBB
等组件放进到每个页面中,就不需要每个页面去引入
在页面使用RootLayout
<template>
<RootLayout>
<div>页面1</div>
</RootLayout>
</template>
onReachBottom
尽管在components
中能使用,但是还是需要在page
的钩子中存在,函数里都可以不写逻辑,但是得在page
的钩子中存在/src/components/MoreLoading.vue
<template> <div class="boxLoading" v-if="isShow"> <span class="text">加载中</span> </div> </template> <script> export default { props: { isShow: { type: Boolean, default: false } } } </script> <style lang="less" scoped> .boxLoading { width: 40rpx; height: 100rpx; margin: auto; position: relative; white-space: nowrap; .text { font-size: 22rpx; color: #b5b8bc; position: absolute; top: 60rpx; left: 50%; transform: translateX(-50%); } &:before { content: ""; width: 40rpx; height: 5px; background: #eeeeee; position: absolute; top: 69rpx; left: 0; border-radius: 50%; animation: shadow 0.5s linear infinite; } &:after { content: ""; width: 40rpx; height: 40rpx; background: #03d0a9; animation: animate 0.5s linear infinite; position: absolute; top: 0; left: 0; border-radius: 3px; } } @keyframes animate { 17% { border-bottom-right-radius: 3px; } 25% { transform: translateY(9px) rotate(22.5deg); } 50% { transform: translateY(18px) scale(1, 0.9) rotate(45deg); border-bottom-right-radius: 40px; } 75% { transform: translateY(9px) rotate(67.5deg); } 100% { transform: translateY(0) rotate(90deg); } } @keyframes shadow { 0%, 100% { transform: scale(1, 1); } 50% { transform: scale(1.2, 1); } } </style>
/src/components/Loadmore.vue
<template> <div> <MoreLoading :isShow="loading" /> <div class="tip-text" v-if="currentText">{{currentText}}</div> </div> </template> <script> import { onReachBottom } from '@dcloudio/uni-app' import { onMounted, reactive, toRefs, watch } from 'vue' import MoreLoading from '@/components/MoreLoading' import { defaultPageConfig } from '@/utils' const maxDataTips = '我也是有底线的~' export default { props: { isShow: { type: Boolean, default: true }, isShowEmptyTips: { type: Boolean, default: false }, suggestLoad: { type: Boolean, default: false }, getLoadingStatus: { type: Function, default: (loading = []) => {} }, updateList: { type: Function, default: (list = []) => {} }, fetchMoreList: { type: Function, default: () => {} } }, components: { MoreLoading }, setup (props) { const pagination = { current: 1, total: 0, totalPage: 1 } const state = reactive({ loading: false, currentText: '', list: [] }) watch(() => state.list, () => { props.updateList && props.updateList(state.list) }) watch(() => props.isShow, () => { pagination.current = 1 state.currentText = '' if (props.isShow) { state.list = [] getPageList() } }) onMounted(() => { if (props.isShow) getPageList() }) const setLoading = (loading) => { state.loading = loading props.getLoadingStatus && props.getLoadingStatus(loading) } const getPageList = () => { if (props.fetchMoreList) { setLoading(true) const page = pagination.current props.fetchMoreList({ page, per_page: defaultPageConfig.per_page }) .then((res) => { setTimeout(() => { const pageInfo = res?.data || {} pagination.total = pageInfo.total pagination.totalPage = Math.ceil(pageInfo.total / pageInfo.per_page) const list = res?.list || [] if (props.isShowEmptyTips && page === 1 && list?.length === 0) { state.currentText = '暂无数据' } if (props.suggestLoad && page !== 1 && list?.length === 0) { state.currentText = maxDataTips } state.list = [...state.list, ...list] setLoading(false) }, 500) }) .catch(() => { setLoading(false) }) } } onReachBottom(() => { console.log('---onReachBottom') if (state.loading) { return } if (!props.suggestLoad && pagination.current >= pagination.totalPage) { state.currentText = maxDataTips } if (state.currentText === maxDataTips) { return } pagination.current = pagination.current + 1 getPageList() }) return { ...toRefs(state) } } } </script> <style lang="less" scoped> .tip-text { text-align: center; color: #999; font-size: 24rpx; height: 80rpx; line-height: 80rpx; } </style>
使用
<template>
<Loadmore :fetchMoreList="fetchList" :updateList="updateList" />
</template>
重写富文本样式用标签不行的,因为小程序中rich-text
会把整个富文本内容加到nodes上,并不会生成标签
1、使用正则给标签加上类名,然后再写这些类名的样式,再引入到App.vue
export const editorHtmlLabel = [ 'h1', 'h2', 'h3', 'h4', 'strong', 'p', 'a', 'table', 'thead', 'tbody', 'th', 'tr', 'td', 'img' ] export function replaceClass (str = '') { const regStr = `(${editorHtmlLabel.map(item => `<${item}`).join('|')})` return str.replace(new RegExp(regStr, 'gi'), function (t) { return `${t} class="editor-${t.slice(1)}" ` }) .replace(/<a.*?>|<\/a>/g, '') // 小程序打开外链条件严苛,看需求是否需要屏蔽链接 }
/src/styles/editor.less
.editor-content { font-family: 'PingFang SC'; color: #2F3033; font-size: 30rpx; word-break: break-all; .editor-h1 { color: #232426; font-size: 34rpx; font-weight: bold; margin-bottom: 30rpx; } .editor-h2 { color: #232426; font-size: 32rpx; font-weight: bold; margin-bottom: 28rpx; } .editor-h3 { color: #232426; font-size: 30rpx; margin-bottom: 24rpx; } .editor-h4 { color: #232426; font-size: 28rpx; margin-bottom: 22rpx; } .editor-strong { display: inline-block; margin: 10rpx 0 4rpx 0; } .editor-p { margin-bottom: 16rpx; } .editor-a { color: inherit; } .editor-img-container { max-width: 100%; overflow-x: auto; } .editor-img { max-width: 100%; } .editor-table { border-collapse: collapse; .editor-tr { &:first-child { .editor-td { border-top: 1px solid #666; } } .editor-td { border-right: 1px solid #666; border-bottom: 1px solid #666; &:first-child { border-left: 1px solid #666; } } } } }
引入到App.vue中
@import "@/styles/editor.css";
使用replaceClass
函数生成标签的class
名
<template>
<div class="editor-content">
<div v-html="$utils.replaceClass(detail.content)"></div>
</div>
</template>
文本和富文本结合的这种,css控制的文本溢出效果会在ios上失效,这种情况我们要把样式加在富文本上
需要再外层再套一层div,并写上style
export function replaceSearchText (str = '', searchText = '', maxLine = 2) {
const reg = new RegExp(searchText, 'i')
const result = str.replace(reg, function (t) {
return `<span style="color: #00BCA8;">${t}</span>`
})
let style = ''
if (maxLine) {
style = `style="overflow: hidden;text-overflow: ellipsis;display: -webkit-box;-webkit-line-clamp: ${maxLine};-webkit-box-orient: vertical;word-break: break-all;"`
}
return `<div ${style}>${result}</div>`
}

mounted () {
// #ifdef MP-WEIXIN

const btnInfo = wx.getMenuButtonBoundingClientRect()
this.btnInfo = btnInfo
// #endif

自 2022 年 10 月 25 日 24 时后(以下统称 “生效期” ),用户头像昵称获取规则将进行如下调整:
wx.getUserProfile 接口将被收回;wx.getUserInfo 接口获取用户昵称头像将被收回;
新的获取用户头像和昵称的方式采用下方自定义的模式:

小程序的功能不断的增加,但是旧版本的微信客户端并不支持新功能,所以在使用这些新能力的时候需要做兼容。
加上下面css能解决大部分的问题
page {
width: 100%;
overflow-x: hidden;
}
但是还有这种可能,就是使用了padding
,但是没有用box-sizing
,也会出现ios上可以横向拖动
.container {
padding: 40rpx;
box-sizing: border-box;
}

1、微信小程序编译模块安装
npm i miniprogram-ci -D
2、小程序微信管理后台设置
小程序后台开发设置里面启用小程序代码上传,下载密匙文件放到项目里,添加ip白名单,此处是公网白名单,公网白名单查询链接
3、在package.json 的 “scripts”: 自定义编译命令
"upload": "npm run build:mp-weixin && node autoUpload.js",
4、创建autoUpload.js 放在 package.json同级目录
const ci = require('miniprogram-ci') const shelljs = require('shelljs') const path = require('path') const mainfest = require('./src/manifest.json') const targetFile = path.resolve(__dirname, './package.json') const packagejson = require(targetFile) const currentVersion = packagejson.version const versionArr = currentVersion.split('.') const [mainVersion, subVersion, phaseVersion] = versionArr // 默认版本号 const newVersion = `${mainVersion}.${subVersion}.${Number(phaseVersion) + 1}` async function upload () { const project = new ci.Project({ appid: mainfest['mp-weixin'].appid, // appid type: 'miniProgram', projectPath: path.resolve(__dirname, './dist/build/mp-weixin'), // 项目路径 privateKeyPath: path.resolve(__dirname, `./private.${mainfest['mp-weixin'].appid}.key`), // 小程序后台的上传密匙 ignores: ['node_modules/**/*'] }) ci.upload({ project, version: newVersion, desc: mainfest.description, setting: { es6: true, // es6 转 es5 es7: true, // 增强编译 disableUseStrict: true, autoPrefixWXSS: true, // 上传时样式自动补全 minifyJS: true, minifyWXML: true, minifyWXSS: true }, onProgressUpdate: console.log }).then(res => { console.log(res) console.log(`上传成功,appId==${mainfest['mp-weixin'].appid},版本号==${newVersion}`) shelljs.sed('-i', `"version": "${currentVersion}"`, `"version": "${newVersion}"`, path.resolve(__dirname, './package.json')) // 同步更新项目中的版本号 }).catch(error => { console.log(`上传失败,appId==${mainfest['mp-weixin'].appid},版本号==${newVersion}`) throw error }) }; upload()
坑点:manifest.json 里面默认有注释,应该删除所有注释,不然会报json转换错误
5、运行 npm upload ,如开发者工具未登陆 则需要登陆,成功后的图片如下:
