一、项目简述
taro-chatroom是基于Taro多端实例聊天项目，运用Taro+react+react-redux+taroPop+react-native等技术开发的仿微信App界面聊天室，实现了发送消息/emoj表情、gif表情大图、图片预览、发红包、动态圈等功能。
二、预览效果
编译到H5端、小程序、App端效果如下：(后续大图均为APP端)
三、技术栈
- 编码/技术：Vscode + react/taro/redux/RN
- iconfont图标：阿里字体图标库
- 自定义导航栏Navigation + 底部Tabbar
- 弹窗组件：taroPop（基于Taro封装自定义模态框）
- 支持编译：H5端 + 小程序 + App端

import Taro, { Component } from ‘@tarojs/taro‘
import Index from ‘./pages/index‘
// 引入状态管理redux
import { Provider } from ‘@tarojs/redux‘
import { store } from ‘./store‘
// 引入样式
import ‘./app.scss‘
import ‘./styles/fonts/iconfont.css‘

navigationBarTextStyle: ‘black‘,

// 请勿修改此函数
render () {
return (
<Provider store={store}>
<Index />
</Provider>

}
}
Taro.render(<App />, document.getElementById(‘app‘))
◆ Taro自定义顶部Navigation导航条 + Tabbar菜单
- 由于项目需求，顶部导航栏/底部tabbar均为自定义组件，详情见：Taro多端自定义导航栏Navbar+Tabbar实例
- 项目中用到的弹窗插件是基于Taro自定义模态框组件，参看：Taro自定义模态框组件
◆ 登录/注册验证模块

import Taro from ‘@tarojs/taro‘
import { View, Text, ScrollView, Image, Input, Button } from ‘@tarojs/components‘
import ‘./index.scss‘
import { connect } from ‘@tarojs/redux‘
import * as actions from ‘../../../store/action‘...
class Login extends Taro.Component {

}
constructor(props) {
super(props)
this.state = {

}
}
componentWillMount() {
// 判断是否登录
storage.get(‘hasLogin‘).then(res => {
if(res && res.hasLogin) {
Taro.navigateTo({url: ‘/pages/index/index‘})

// 提交表单

const mapStateToProps = (state) => {
return {...state.auth}
}
export default connect(mapStateToProps, {

taro本地存储使用的是异步存储，由于同步存储不支持RN端
/**
* @desc Taro本地存储
*/
import Taro from ‘@tarojs/taro‘
export default class Storage {
static get(key) {
return Taro.getStorage({ key }).then(res => res.data).catch(() => ‘‘)
}
static set(key, data){
return Taro.setStorage({key: key, data: data}).then(res => res)
}
static del(key){
Taro.removeStorage({key: key}).then(res => res)
}
static clear(){
Taro.clearStorage()
}
}
如不希望编译到RN端，使用如下包裹即可
/*postcss-pxtransform rn eject enable*/
/*postcss-pxtransform rn eject disable*/
对于一些RN端不兼容样式，边框、超过多行...，需特殊样式处理
/*
* 对于不兼容的样式，如RN不兼容border-right，可以通过mixin统一处理
*/
/**
* RN 不支持针对某一边设置 style，即 border-bottom-style 会报错
* 那么 border-bottom: 1px 就需要写成如下形式： border: 0 style color; border-bottom-width: 1px;
*/
@mixin border($dir, $width, $style, $color) {
border: 0 $style $color;
@each $d in $dir {
#{border-#{$d}-width}: $width;
}
}
/**
* NOTE RN 无法通过 text-overflow 实现省略号，这些代码不会编译到 RN 中
*/
@mixin ellipsis {
/*postcss-pxtransform rn eject enable*/
overflow: hidden; white-space: nowrap; text-overflow: ellipsis;
/*postcss-pxtransform rn eject disable*/
}
/**
* NOTE 实现多行文本省略，RN 用 Text 标签的 numberOfLines={2}，H5/小程序用 -webkit-line-clamp
*/
@mixin clamp($line) {
/*postcss-pxtransform rn eject enable*/
display: -webkit-box;
overflow: hidden;
-webkit-line-clamp:$line;
/* autoprefixer: ignore next */
-webkit-box-orient: vertical;
/*postcss-pxtransform rn eject disable*/
}
/**
* 对于不能打包到 RN 的样式，可以用 postcss 方式引入
*/
@mixin eject($attr, $value) {
/*postcss-pxtransform rn eject enable*/
#{$attr}: $value;
/*postcss-pxtransform rn eject disable*/
}
◆ Taro聊天实现消息滚动到底部
在taro中实现聊天消息滚动到最底部，由于RN端不支持 createSelectorQuery，如是做了兼容处理。
componentDidMount() {
if(process.env.TARO_ENV === ‘rn‘) {
this.scrollMsgBottomRN()
}else {
this.scrollMsgBottom()
}
}
// 滚动至聊天底部
scrollMsgBottom = () => {
let query = Taro.createSelectorQuery()
query.select(‘#scrollview‘).boundingClientRect()
query.select(‘#msglistview‘).boundingClientRect()
query.exec((res) => {
// console.log(res)
if(res[1].height > res[0].height) {
this.setState({ scrollTop: res[1].height - res[0].height })
}
})
}
scrollMsgBottomRN = (t) => {
let that = this
this._timer = setTimeout(() => {
that.refs.ScrollViewRN.scrollToEnd({animated: false})
}, t ? 16 : 0)
}
聊天中表情使用的是emoj表情符，如果使用图片做表情也是可以，不过需要一些特殊匹配处理 :12) [:高兴]，使用emoj就相对简单些罢了。
// 渲染消息记录
renderMsgTpl = (data) => {
return data.map((item, index) => (
<View key={index}>
{item.msgtype == 1 &&
<View className="msgitem msg__time"><Text className="msg__text">{item.msg}</Text></View>
}
{item.msgtype == 2 &&
<View className="msgitem msg__notice"><Text className="msg__text">{item.msg}</Text></View>
}
{item.msgtype == 3 &&
<View className="msgitem">
{!item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
<View className={`msg__cntbox ${item.isme ? ‘msg-me‘ : ‘msg-others‘}`}>
<Text className="msg-author">{item.author}</Text>
<View className={`msg__cnt ${item.isme ? ‘msg__cnt-me‘ : ‘msg__cnt-others‘}`} onLongPress={this.handleLongPressMenu}>
<Text className="msg__cnt-text">{item.msg}</Text>
</View>
</View>
{item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
</View>
}
{item.msgtype == 4 &&
<View className="msgitem">
{!item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
<View className={`msg__cntbox ${item.isme ? ‘msg-me‘ : ‘msg-others‘}`}>
<Text className="msg-author">{item.author}</Text>
<View className={`msg__cnt ${item.isme ? ‘msg__cnt-me‘ : ‘msg__cnt-others‘} msg__lgface`} onLongPress={this.handleLongPressMenu}>
<Image className="msg__lgface-img" src={item.imgsrc} mode="widthFix" />
</View>
</View>
{item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
</View>
}
{item.msgtype == 5 &&
<View className="msgitem">
{!item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
<View className={`msg__cntbox ${item.isme ? ‘msg-me‘ : ‘msg-others‘}`}>
<Text className="msg-author">{item.author}</Text>
<View className={`msg__cnt ${item.isme ? ‘msg__cnt-me‘ : ‘msg__cnt-others‘} msg__picture`} onClick={this.handlePreviewPicture.bind(this, item.imgsrc)} onLongPress={this.handleLongPressMenu}>
<Image className="msg__picture-img" src={item.imgsrc} mode="widthFix" />
</View>
</View>
{item.isme ? <View className="msg__avator"><Image className="msg__avator-img" src={item.avator} mode="aspectFit" /></View> : null}
</View>
}
...
</View>
))
