如何在网页端实现一个仿微信的聊天窗口

Posted 2023-04-16

参考技术A 　其实那个二维码就是一个网址，你扫描完，手机就发送了一个http请求，这个GET请求发送一些数据给微信的服务器，微信收到这个请求校验以后就返回到手机，手机上出现一个确认页面，点击以后在服务器完成鉴权，然后在web端更新页面（看样子web有个监听是否完成请求的js?） 参考技术B 不理解
仿手机微信吗？ 参考技术C 直接搜网页微信

react网页版聊天|仿微信微博web版|react+pc端仿微信实例

一、项目介绍

基于react+react-dom+react-router-dom+redux+react-redux+webpack2.0+nodejs等技术混合开发的仿微信web端聊天室reactWebChat项目，实现了聊天记录右键菜单、发送消息、表情(动图)，图片、视频预览，浏览器截图粘贴发送等功能。

二、技术选型

• MVVM框架：react / react-dom
• 状态管理：redux / react-redux
• 页面路由：react-router-dom
• 弹窗插件：wcPop
• 打包工具：webpack 2.0
• 环境配置：node.js + cnpm
• 图片预览：react-photoswipe
• 轮播滑动：swiper

◆ App主页面布局及路由配置：

render() 
    let token = this.props.token
    return (
      <Router>
        <div className="vChat-wrapper flexbox flex-alignc">
          <div className="vChat-panel" /*style= backgroundImage: `url($require("./assets/img/placeholder/vchat__panel-bg02.jpg"))` */ >
            <div className="vChat-inner flexbox">
              /* //顶部（最大、最小、关闭） */
              <Switch>
                <WinBar />
              </Switch>

              /* //侧边栏 */
              <Switch>
                <SideBar />
              </Switch>

              /* //主页面 */
              <div className="flex1 flexbox">
                /* 路由容器 */
                <Switch>
                  
                    routers.map((item, index) => 
                      return <Route key=index path=item.path exact render=props => (
                        !item.meta || !item.meta.requireAuth ? (<item.component ...props />) : (
                          token ? <item.component ...props /> : <Redirect to=pathname: ‘/login‘, state: from: props.location />
                        )
                      ) />
                    )
                  
                  /* 初始化页面跳转 */
                  <Redirect push to="/index" />
                </Switch>
              </div>
            </div>
          </div>
        </div>
      </Router>
    );

◆ react+react-redux配合状态管理：

import combineReducers from ‘redux‘
import defaultState from ‘./state.js‘

function auth(state = defaultState, action) 
    // 不同的action处理不同的逻辑
    switch (action.type) 
        case ‘SET_TOKEN‘:
            return 
                ...state, token: action.data
            
        case ‘SET_USER‘:
            return 
                ...state, user: action.data
            
        case ‘SET_LOGOUT‘:
            return 
                user: null, token: null
            
        default:
            return  ...state 
    

◆ react页面路由配置：
