◆ 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:

/*

// 引入页面组件

                elems。length = 0;
            })();
        }

// 定义最后光标位置
