React-router-dom：单击“链接”可将路由无限期添加到“ URL链接”

Question

经过几次尝试，我已经设法通过React-router-dom实现了基本的嵌套路由。
这是简单的项目结构：

以下是相关文件：

App.js

import React from "react";
import logo from "./logo.svg";
import "./App.css";
import { BrowserRouter, Switch, Route } from "react-router-dom";

import ParentComponent from "./Components/nestedComponents/ParentComponent";
import NavBar from "./Components/Shared/NavBar";
function App() {
  return (
    <div className="App">
      <BrowserRouter>
        <NavBar />
        <Switch>
          <Route path="/home" name="Home" component={ParentComponent} />
        </Switch>
      </BrowserRouter>
    </div>
  );
}

export default App;

NavBar.js

import React from "react";
import { Link } from "react-router-dom";

export default function NavBar() {
  return (
    <div>
      <Link to={`home/nestedComponentOne`}> Nested Component One </Link>
      <Link to={`home/nestedComponentTwo`}> Nested Component Two </Link>
    </div>
  );
}

ParentComponent.js

import React from "react";
import nestedComponentOne from "./nestedComponentOne";
import nestedComponentTwo from "./nestedComponentTwo";
import { Switch, Route } from "react-router-dom";

export default function ParentComponent() {
  return (
    <div>
      <Switch>
        <Route path="/home/nestedComponentOne" component={nestedComponentOne} />
        <Route path="/home/nestedComponentTwo" component={nestedComponentTwo} />
      </Switch>
    </div>
  );
}

nestedComponentOne.js

import React from "react";

export default function nestedComponentOne() {
  return <div>NESTED COMPONENT 1</div>;
}

nestedComponentTwo.js

import React from "react";

export default function nestedComponentTwo() {
  return <div>NESTED COMPONENT 2</div>;
}

所以这是结果：
如果单击 nestedComponentOne ：

如果我点击 nestedComponentTwo ：

问题是当我第一次单击 nestedComponentOne （或两个）后，将路由添加到 URL字符串，而不是替换它：

Answer 1

您的代码需要一些更新。 Working Demo

NavBar.js

在这里您忘了在前面添加斜杠/以便从根链接。

      <Link to={`/home/nestedComponentOne`}> Nested Component One </Link>
      <Link to={`/home/nestedComponentTwo`}> Nested Component Two </Link>

ParentComponent.js

当我们从组件中删除Switch时，我们需要从父路由器获取匹配信息，并传递路径以导航相应的嵌套组件

     export default function ParentComponent({ match }) {
      return (
        <div> 
          <Route path={`${match.path}/nestedComponentOne`} component={nestedComponentOne} />
          <Route path={`${match.path}/nestedComponentTwo`} component={nestedComponentTwo} />
        </div>
      );
    }

为什么不尝试将所有路由都放在一个文件中。像这样：

<Route exact path="/home" name="Home" component={ParentComponent} />
<Route path="/home/nestedComponentOne" component={nestedComponentOne} />
<Route path="/home/nestedComponentTwo" component={nestedComponentTwo} />
