react-router-dom 嵌套路由的实现

入口文件index.js：

import React from "react"
import ReactDOM from "react-dom"
import App from "./App.jsx"
import "babel-polyfill"
const root = document.getElementById("app")
if (root !== null) {
 ReactDOM.render(<App />, document.getElementById("app"))
}

各个文件的详细位置：

主要目录App.jsx:

import React, { Fragment, Component } from "react"
import {
 BrowserRouter as Router,
 Switch,
 Route,
 NavLink,
 Redirect,
 Link,
 withRouter,
} from "react-router-dom"
// 开始引入各种自定义的组件
import Index from "./pages/platform/index"
//404页面
import ErrorPage from "./pages/ErrorPage"
import Login from "./pages/login/index"
import routes from "./routes/index"


class BaseLayout extends Component {
 constructor(props) {
  super(props)
  }
  
  render(){
    return(
    <Fragment>
      <ul>
     {routes.map((val,index))=>{
       return(
       <li key={index}>
       <Link to={val.path}>{val.authName}</Link>
       </li>
       )
     }
    </ul>
      
       <Switch>
        {routes.map((route, key) => {
         if (route.exact) {
          return (
           <Route
            key={key}
            exact
            path={route.path}
            component={(props) => {
             return (
              <route.component {...props} routes={route.routes} />
             )
            }}
           >
            {/* <route.component /> */}
           </Route>
          )
         } else {
          return (
           <Route
            key={key}
            path={route.path}
            component={(props) => {
             return (
              <route.component {...props} routes={route.routes} />
             )
            }}
           >
            {/* <route.component /> */}
           </Route>
          )
         }
        })}
        <Route path="/">
         <Index />
        </Route>
        <Route path="*">
         <ErrorPage />
        </Route>
       </Switch>
    </Fragment>
    )
  } 
}

class App extends React.Component {
 constructor(props) {
  super(props)
 }
 render() {
  return (
    <Router>
     <Switch>
      <Route path="/login">
       <Login />
      </Route>
      <Route path="/">
       <BaseLayout />
      </Route>
       <!--<Route path="*">-->
       <!--   <ErrorPage />-->
       <!--  </Route>-->
     </Switch>
    </Router>
  )
 }
}

export default App

放路由route.js:

import Index from "../pages/platform/index"
import UserAdd from "../pages/component/User/UserAdd"
import UserList from "../pages/component/User/UserList"

const routes = [
 {
  path: "/index",
  authName: "首页",
  component: Index,
  exact: true,
 },
 {
  path: "/user",
  authName: "用户1",
  component: UserList,
 },
 {
  authName: "用户2",
  path: "/userAdd",
  component: UserAdd,
 },
]
export default routes

其他页面login.jsx：

import React, { Component } from "react"

export default class Login extends Component {
 render() {
  return <div>Login</div>
 }
}

其他页面index.jsx：

import React, { Component } from "react"

export default class Index extends Component {
 render() {
  return <div>Index</div>
 }
}

其他页面UserAdd.jsx：

import React, { Component } from "react"

export default class UserAdd extends Component {
 render() {
  return <div>UserAdd</div>
 }
}

其他页面UserList.jsx：

import React, { Component } from "react"

export default class UserList extends Component {
 render() {
  return <div>UserList</div>
 }
}
