Taro聊天室|react+taro仿微信聊天App界面|taro聊天实例

2019-12-14 14:54 295 查看

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

/**
* @desc   Taro入口页面 app.jsx
* @about Q:282310962 wx:xy190310 */ 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' import './styles/reset.scss' class App extends Component { config = { pages: [ 'pages/auth/login/index', 'pages/auth/register/index', 'pages/index/index', ... ], window: { backgroundTextStyle: 'light', navigationBarBackgroundColor: '#fff', navigationBarTitleText: 'TaroChat', navigationBarTextStyle: 'black', navigationStyle: 'custom' } } // 在 App 类中的 render() 函数没有实际作用 // 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

◆ 登录/注册验证模块

return (

<ScrollView className="taro__scrollview flex1" scrollY>

/**
* @tpl 登录模块
*/

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 {
config = {

1044
navigationBarTitleText: '登录'
}
constructor(props) {
super(props)
this.state = {
tel: '',
pwd: '',
}
}
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
handleSubmit = () => {
let taroPop = this.refs.taroPop
let { tel, pwd } = this.state

if(!tel) {
taroPop.show({content: '手机号不能为空', time: 2})
}else if(!util.checkTel(tel)) {
taroPop.show({content: '手机号格式有误', time: 2})
}else if(!pwd) {
taroPop.show({content: '密码不能为空', time: 2})
}else {
// ...接口数据
...

storage.set('hasLogin', { hasLogin: true })
storage.set('user', { username: tel })
storage.set('token', { token: util.setToken() })

taroPop.show({
skin: 'toast',
content: '登录成功',
icon: 'success',
time: 2
})

...
}
}

render () {
...
}
}

const mapStateToProps = (state) => {
return {...state.auth}
}

export default connect(mapStateToProps, {
...actions
})(Login)

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__n
ad8
otice"><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 class
1664
Name="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>
))
}
