javascript - PrivateRoute 在 reactjs react-router-dom 中不起作用

Question

在我的 react.js 项目中集成 PrivateRoute HOC 时，我完全卡住了。

这是我的路线文件

import React, { Component } from "react";
import { Route, Redirect, Switch, BrowserRouter as Router } from 'react-router-dom';
import Dashboard from "../view/Dashboard/Dashboard";
import Login from "../view/Login/Login";
import Admin from "../view/UserManagement/Admin";
import cookie from 'react-cookies'

const PrivateRoute = ({ component, ...rest }) => {
  const isAuthed = cookie.load('token')
  console.log(isAuthed, 'dddddddddddddddddddd')
  return (
    <Route {...rest} exact
      render = {(props) => (
        isAuthed ? (
          <div>
            {React.createElement(component, props)}
          </div>
        ) :
        (
          <Redirect
            to={{
              pathname: '/login',
              state: { from: props.location }
            }}
          />
        )
      )}
    />
  )
}

class MainPanel extends Component {

  render() {
    return (
      <div style={{ direction: direction }}> 
        <Router>
          <Switch>
            <Route path="/login" component={Login}/>
            <PrivateRoute path="/" component={Dashboard} />
            <PrivateRoute path="/AdminManagement" component={Admin} />
           </Switch>
        </Router>
      </div>
    )
  }
}
export default withNamespaces('common') (MainPanel);

我对此完全崩溃了，但并没有摆脱那个问题。为什么我在 PrivateRoute 中的控制台不显示值

react 和 react-router-dom 版本有什么问题吗

提前致谢!!!

您拥有的 PrivateRoute 组件是正确的，但是您只需要重新排序您的 Routes 即可使它们正常工作。 /AdminManagement 路由应该在 / 之前，因为 Switch 呈现第一个匹配的 Route 并且 Route path 也将匹配其前缀路径

class MainPanel extends Component {

  render() {
    return (
      <div style={{ direction: direction }}> 
        <Router>
          <Switch>
            <Route path="/login" component={Login}/>
            <PrivateRoute path="/AdminManagement" component={Admin} />
            <PrivateRoute path="/" component={Dashboard} />
           </Switch>
        </Router>
      </div>
    )
  }
}
export default withNamespaces('common') (MainPanel);
