在react-router-dom中出現404錯誤

Question

我已經開始使用react-router-dom。 我的主頁成功渲染，但是當我單擊Link組件提供的超級Link它沒有重定向，但是如果我手動點擊url，則會出現404錯誤。 請幫我嗎？

這是我的配置文件

import React from 'react'
import { render } from 'react-dom'
import { createStore, applyMiddleware,compose } from 'redux'
import { Provider } from 'react-redux'
//import rootReducer from './reducers'
import createLogger from 'redux-logger'
import thunk from 'redux-thunk'
import {BrowserRouter} from 'react-router-dom'

import promise from "redux-promise-middleware"
import logger from "redux-logger"
import {fetchUsers} from "./action/UserAction"
import {fetchChart} from "./action/ChartAction"
import {fetchNames} from "./action/SearchAction"
import reducer from "./reducers"
import routes from "./routes"

const middleware = applyMiddleware(promise(), thunk, logger())
const store= createStore(reducer,middleware)

store.dispatch(fetchUsers());
store.dispatch(fetchChart());
render(
  <Provider store={store}>
    <BrowserRouter >
      {routes}
    </BrowserRouter>

  </Provider>,
  document.getElementById('root')
)

我的路線文件

import App from "./pages/App"
import Users from "./pages/Users"
import Charts from "./pages/Charts"
import React from "react"
import { Route } from "react-router-dom"
export default (
  <switch>
  <Route path="/" component={App}/>
  <Route path="/users" component={Users}/>
    <Route path="/charts" name="charts" component={Charts}/>
 </switch>

);

App.js

import {Link} from "react-router-dom"
import React from "react"
const App = () =>(

<div>
<h1> this is main page </h1>
<Link to="charts">charts</Link>
</div>
)

export default App

Users.js

import React from "react"
const User = () =>(
    <div>
    <h1> this is user </h1>
    </div>
)

export default User

Charts.js

import React from "react"
const Chart = () => (
    <h1> this is chart </h1>
)

export default Chart

更新1 ：我不知道發生了什么。 但是我通過單擊url更改了routes.js中的序列，它可以正常工作。 但是，即使我手動點擊網址或刷新網址，仍然無法正常工作。 下面是我更新的routes.js

import App from "./pages/App"
import Users from "./pages/Users"
import Charts from "./pages/Charts"
import React from "react"
import { Route,Switch } from "react-router-dom"

export default (
  <Switch>
    <Route  path="/charts"  component={Charts}/>
    <Route  path="/users" component={Users}/>
  <Route path="/" component={App}/>


 </Switch>

);

更新2：如果我使用的是確切路徑，則順序無關緊要。 我認為我不正確理解確切路徑的使用。 但是仍然手動點擊url或刷新時對我來說我的最終route.js不起作用

import App from "./pages/App"
import Users from "./pages/Users"
import Charts from "./pages/Charts"
import React from "react"
import { Route,Switch } from "react-router-dom"

export default (
  <Switch>


  <Route exact path="/" component={App}/>
  <Route  exact path="/charts"  component={Charts}/>
  <Route exact path="/users" component={Users}/>

 </Switch>

);

Answer 1

掙扎之后，我收到一條SO帖子，說如果我的數據不是從后端映射的，則應使用HashRouter。 因此，我更改了瀏覽器，因此將代碼更改為此。 但我不知道為什么瀏覽器路由器不起作用

<Provider store={store}>
    <HashRouter >
      {routes}
    </HashRouter>

  </Provider>,
  document.getElementById('root')

如果您使用的是webpack，請添加

devServer: {
    historyApiFallback: true,
}

使用BrowserRouter“historyApiFallback”的時候應該是真實的
