reactjs路由器-设置登录页面

Question

我正在尝试制作一个登录页面，该页面可用作我的应用程序的输入页面，并且在用户输入登录名和密码后，它将打开包含菜单和页面内容的主要组件。

我无法理解如何设置路由器或主应用程序结构的问题，这样它就可以按我的意愿工作。 到目前为止，我可以同时显示带有主菜单栏的登录组件，或者仅显示没有工作页面的登录页面。

有我的路由器

import React from 'react'
import ReactDOM from 'react-dom' 
import {Router, Route, IndexRoute, hashHistory} from 'react-router'
import App from './App'
import LoginPage from './pages/login'
import Forms from './pages/Forms'
import Home from './pages/Home'

ReactDOM.render(
  <Router history={hashHistory}>
    <Route path ="/" component={App}>
      <IndexRoute component={LoginPage} />
      <Route exact path='/LoginPage' component={LoginPage} />
      <Route exact path='/App' component={App} />
      <Route exact path='/Home' component={Home} />
      <Route exact path='/Forms' component={Forms} />
    </Route>   
  </Router>, document.getElementById('root'))

我的登录页面

import React, { Component } from 'react'
import { Link } from "react-router"
import logo from './logo.jpg';

export default class LoginPage extends Component {
  render() {
    return (
        <div className="login-page">
            <div className="login-form-cont">
                <div style={{paddingBottom:'10px'}}> <img src={logo} width="270" height="54" /> </div>
                <form className="login-form">
                    <input type="text" placeholder="username"/>
                    <input type="password" placeholder="password"/>
                    <Link to={`/Home`}> 
                        <button> login </button>  
                    </Link>
                </form>
            </div>
        </div> 
    )
  }
}

和我的app.js

import React, { Component } from 'react'
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider'
import getMuiTheme from 'material-ui/styles/getMuiTheme'
import classnames from 'classnames'
import SideBarMenu from './components/SidebarMenu'

export default class App extends Component {
    constructor(props){
    super(props)
    this.state = {open: false}
  }

  render() {
  return (

      <MuiThemeProvider muiTheme={muiTheme}>
      <div >
          <SideBarMenu/>
          <div className={classnames('app-content')}>
              { this.props.children }
          </div>
      </div>
      </MuiThemeProvider>
      )
  }
}

我试图使路由器从登录组件开始，但是在这种情况下，即使浏览器窗口中的地址发生了变化，屏幕本身也没有变化

我正在使用React Router 3.2和React 15.6

首先，我将建议您使用react-router v4 cos，我将向您显示。 并且v4是较旧版本的beta版本。

import { BrowserRouter, Switch, Route } from 'react-router-dom';

export default class App extends Component{
  render(){
    return (
     <BrowserRouter>
        <Switch>
           <Route exact path="/" component={Login}/>
           <Route exact path="/Home" component={Home}/>
           <Route exact path="/Dashboard" component={Dashboard} />
           <Route exact path="/Dashboard/:userId" component={Dashboard}/>
           <Route component={NotFound}/>
        </Switch>
      </BrowserRouter>
    )
  }
}
