无法在反应路由器中呈现反应组件

Question

我有一个反应应用程序。

我在组件路由方面遇到问题

索引.js

import React from "react";
import ReactDOM from "react-dom";

import App from './app';

ReactDOM.render(
  <App/>,
  document.getElementById("root")
);

应用程序.jsx

我在这里路由 2 组件。登录和主要组件。在主要组件中有许多路由器将用于仪表板。

我的问题：在<Switch>第一个<Route>可以渲染但如果我在 url 中硬编码，它不会从第二个路由器渲染

http://localhost:3000/#/login == 渲染

http://localhost:3000/#/main = 不渲染

import React, { Component } from 'react';
import {
    BrowserRouter as Router,
    Route,
    Link,
    Switch
} from 'react-router-dom';

import Login from './login';
import Main from './main';

import createBrowserHistory from 'history/createBrowserHistory';
const customHistory = createBrowserHistory();

class App extends Component {
    constructor(props) {
        super(props);

        window.token = '';
    }

    render() {
        return <div>
                <Router>
                    <Switch>
                        <Route to="/login" component={Login} exact />
                        <Route to="/main" component={Main} exact/>
                    </Switch>
                </Router>
            </div>;
    }
}

export default App;

主文件

import React, {Component} from 'react';
import ReactDOM from "react-dom";

import { HashRouter, Route, Switch } from "react-router-dom";

import indexRoutes from "routes/index.jsx";

import "bootstrap/dist/css/bootstrap.min.css";
import "./assets/css/animate.min.css";
import "./assets/sass/light-bootstrap-dashboard.css?v=1.2.0";
import "./assets/css/demo.css";
import "./assets/css/pe-icon-7-stroke.css";

import Login from './login';

class Main extends Component {
    constructor(props) {
        super(props);
    }

    render() {
        return <HashRouter>
        <Switch>

          {indexRoutes.map((prop, key) => {
            return <Route to={prop.path} component={prop.component} key={key} />;
          })}
        </Switch>
      </HashRouter>;
    }
}

export default Main;

Answer 1

用

<Route path="/login" component={Login} exact />

而不是to使用path
