你好，如果没有验证，但我尝试保护路由

警告：您不应在同一路径中使用Route组件和Route渲染；路线渲染将被忽略

App.js

  import React, { Fragment, useEffect } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import NavBar from './component/Layout/NavBar';
import Landing from './component/Layout/Landing';
import Login from '../src/component/Auth/Login';
import Register from '../src/component/Auth/Register';
import Dashboard from './component/dashboard/Dashboard';
import Alert from './component/Auth/Alert';
import PrivateRoute from './component/routing/PrivateRoute';

import './App.css';

// Redux
import { Provider } from 'react-redux';
import store from './store';
import setAuthToken from './utils/token';

import { loadUser } from './action/auth';


if (localStorage.token) {
  setAuthToken(localStorage.token);
}
const App = () => {

  useEffect(() => {
    store.dispatch(
      loadUser());
  }, []);

  return (
    <Provider store={store}>
      <Router>
        <Fragment>
          <NavBar />
          <Route exact path="/" component={Landing}></Route>
          <section className="container">
            <Alert />
            <Switch>
              <Route exact path="/login" component={Login}></Route>
              <Route exact path="/register" component={Register}></Route>
              <PrivateRoute exact path="/dashboard" component={Dashboard}></PrivateRoute>
            </Switch>
          </section>
        </Fragment>
      </Router>
    </Provider>
  );
};

export default App;

PrivateRoute.js

import React from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import { Route, Redirect } from 'react-router-dom';

const PrivateRoute = ({
  componet: Component,
  auth: { isAuthenticated, loading },
  ...rest
}) => (
  <Route
    {...rest}
    render={props =>
      !isAuthenticated && !loading ? (
        <Redirect to="/login" />
      ) : (
        <Component {...props} />
      )
    }
  />
);

PrivateRoute.propTypes = {
  auth: PropTypes.object.isRequired
};

const mapStateToProps = state => ({
  auth: state.auth
});

export default connect(mapStateToProps)(PrivateRoute);

我该如何解决？

Answer 1

使用<Route render={() => <YourComponent />} />代替<Route component={YourComponent} />。

不要将其中两个结合在一起，react不会那样。

Answer 2

来自route rendering method：

使用<Route>渲染内容的方式有3种：
- <Route component>
- <Route render>
- <Route children>
每种在不同情况下都是有用的。您应该在给定
上仅仅使用这些道具之一

PrivateRoute包含component和render道具。您只能使用一种渲染方法，但不能同时使用。

<PrivateRoute exact path="/dashboard" component={Dashboard}></PrivateRoute> // here

const PrivateRoute = ({
  ...
}) => (
  <Route
    render={props => ()} // here
  />
);

FIX ：将component道具重命名为comp ，因为它是HOC：

// rename prop to `comp`
<PrivateRoute exact path="/dashboard" comp={Dashboard}></PrivateRoute>

const PrivateRoute = ({
  comp: Component, // use comp prop
  auth: { isAuthenticated, loading },
  ...rest
}) => (
  <Route
    {...rest}
    render={props =>
      !isAuthenticated && !loading ? (
        <Redirect to="/login" />
      ) : (
        <Component {...props} />
      )
    }
  />
);
