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(, 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(
    
      

     {routes.map((val,index))=>{
       return(
       

       {val.authName}
       
       )
     }
    
      
       
        {routes.map((route, key) => {
         if (route.exact) {
          return (
            {
             return (
              
             )
            }}
           >
            {/*  */}
           
          )
         } else {
          return (
            {
             return (
              
             )
            }}
           >
            {/*  */}
           
          )
         }
        })}
        
         
        
        
         
        
       
    
    )
  } 
}

class App extends React.Component {
 constructor(props) {
  super(props)
 }
 render() {
  return (
    
     
      
       
      
      
       
      
       
       
       
     
    
  )
 }
}

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 
Login
 }
}

其他页面index.jsx：

import React, { Component } from "react"

export default class Index extends Component {
 render() {
  return 
Index
 }
}

其他页面UserAdd.jsx：

import React, { Component } from "react"

export default class UserAdd extends Component {
 render() {
  return 
UserAdd
 }
}

其他页面UserList.jsx：

import React, { Component } from "react"

export default class UserList extends Component {
 render() {
  return 
UserList
 }
}
