[JavaScript知识库]react redux 路由拦截、路由守卫

一、创建PrivateRoute.js文件

import React, { Component } from 'react'

import { Route, Redirect } from 'react-router-dom'



function PrivateRoute({ children, ...rest }) {

    // //从仓库取数据
    // var t = Store.getState().chshz
    // console.log(t, 'tttttt');
    // console.log(localStorage.getItem('userLogin'), 'iiii');

    return (
        <Route
            {...rest}
            render={
                ({ location }) =>
                    localStorage.getItem('userLogin') ? (children) : (
                        <Redirect to={{
                            pathname: '/',
                            state: { from: location }
                        }} />
                    )


            }
        />


    )
}


export default PrivateRoute

二：路由设置拦截

import './App.css';
import { Route, Switch } from 'react-router-dom'
import Login from '../Login/Login'
import Home from '../Home/Home';


//路由守卫
import PrivateRoute from '../PrivateRoute'

function App() {
  return (
    <div className="App">


      <Switch>
        {/* 登录页首页 */}
        <Route exact path='/' component={Login}></Route>
        {/* 登录成功页面 */}
        {/* <Route exact path='/home' component={Home}></Route> */}
        <PrivateRoute path='/home'>
          <Route path='/home' component={Home} >

          </Route>

        </PrivateRoute>

      </Switch>
    </div>
  );
}

export default App;

?

三：登录页面

 //登录按钮  
    async login() {
        // console.log(this.state);
        let msg = await getUser('User_Login', 'get', this.state)
        console.log(msg);
        if (msg.data.code == 200) {
            localStorage.setItem('userLogin', this.state)
            this.props.history.push('/home')
            message.success('登录成功！');
        } else {
            message.warning('用户名/密码不正确')
        }
    }
