请查看这段代码并告诉我是否可以帮助我解决问题，

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




function App(){
return(
    <Router>
        <div className = "sidebar">
            <Link to = "/"><h1 className = "heading ">TODOS</h1></Link>
            <Link to= "/login"> <span className = "links login">LogIn</span></Link>
            <Link to = "/signup"><span className = "links signup">SignUp</span></Link>
            <Link to = "contact"><span className = "links contact">Contact Us</span></Link>
            <Link to = "/about"><span className = "links about">About Developer</span></Link>
        </div>
        <Switch>
            <Route path = "/">
                <h1>home route</h1>
            </Route>
            <Route path = "/login">
                {/* <Login/> */}
                <div>
                 <h1>this is login route</h1>
                </div>
            </Route>    
            <Route path = "/signup">
                <h1>signup page</h1>
            </Route>
            <Route path = "/contact">
                <h1>contact page</h1>
            </Route>
            <Route path = "/about">
                <h1>About page</h1>
            </Route>
        </Switch>
    </Router>
)
}

export default App;

NMw 不管你点击哪个 links 它都显示相同的文本我该如何解决这个问题？？为了测试和更好地理解问题，你们可以继续 this link 并复制粘贴我的代码并在那里运行，请让我知道我的错误

只需将 exact 属性添加到 all 路由组件。它会起作用

<Route exact path='/yourpath' />
