如何设置路由器正确反应v3

Question

我正在尝试为我的React项目设置React-Router，但由于某些原因无法正确设置路径。在路由器设置中，Indexroute的组件可以正常工作，但是当我尝试时，要访问注册页面，我会收到错误"无法获取/辛格普"enth。

依赖项：

"dependencies": {
    "express": "^4.16.2",
    "nodemon": "^1.14.12",
    "path": "^0.12.7",
    "react": "^16.2.0",
    "react-dom": "^16.2.0",
    "react-router": "^3.0.5",
    "webpack": "^3.10.0",
    "webpack-dev-middleware": "^2.0.4"
  }

routes.js

import React from 'react'
import { Route, IndexRoute } from 'react-router';
import App from './components/App';
import Greetings from './components/Greetings';
import SignupPage from './components/signup/SignupPage';
export default(
    <Route path="/" component={App} >
        <IndexRoute component={Greetings} />
        <Route path="signup" component={SignupPage} />
    </Route>
) 

app.js

import React, { Component } from 'react';
import NavigationBar from './NavigationBar'

class App extends Component {
    render() {
        return (
            <div className="container">
                <NavigationBar />
                {this.props.children}
            </div>  
        );
    }
}
export default App;

signuppage

import React, { Component } from 'react';
class SignupPage extends Component {
    render() {
        return (
            <div>
                <h1>hey iam sign up page</h1>
            </div>
        );
    }
}
export default SignupPage;

Answer 1

尝试像这样包装路由器组件

import { Router, Route, browserHistory, IndexRoute } from 'react-router';
<Router history={browserHistory}>
    <Route path="/" component={App} >
        <IndexRoute component={Greetings} />
        <Route path="signup" component={SignupPage} />
    </Route>
</Router>

感谢您的答复，这是错误的，在提供文件时是错误的。

在这里，我仅设置"/"的路径，因此，当我发送"/注册"请求时，我会收到错误'无法获取/注册'，因为没有相同的请求映射

app.get('/',(req,res) => {
        // send file as response
        // __dirname -- > points to current director
        res.sendFile(path.join(__dirname,'./index.html'));
    })

要解决它，我必须为任何请求URL

设置请求映射

app.get('/*',(req,res) => {
    // send file as response
    // __dirname -- > points to current director
    res.sendFile(path.join(__dirname,'./index.html'));
})
