如何在match.params中使用React Router？

Question

我正在做项目，我需要用React Router创建一些路由。我的项目是：

每个方块都有一个ID 200和201和，我要单击的每个转弯我都想走一条路线，例如：http://localhost:3000/user/200或http://localhost:3000/user/201何时走那条路线，我希望它出现在body "User 200"或处"User201"，我阅读了文档但不理解。

我的APP.JS：

import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
import './App.css';
import Home from './Home';

const App = () => (
  <Router>
    <Home/>
  </Router>
);


export default App;

我的HOME.JS：

import React from 'react';
import Header from './Header';
import Body from './Body';
import './Home.css';

class Home extends React.Component {
  render() {
    return ( <
      div className = 'home' >
      <
      Header / >
      <
      Body / >
      <
      /div>
    )
  }
}

export default Home;

我的BODY.JS：

import React from 'react';
import './Body.css';
import axios from 'axios';
import {
  Link
} from "react-router-dom";

class Body extends React.Component {
  constructor() {
    super();

    this.state = {
      employee: [],
    }
  }

  componentDidMount() {
    axios.get('http://127.0.0.1:3004/employee').then(
      response => this.setState({
        employee: response.data
      })
    )
  }

  getName = () => {
    const {
      employee
    } = this.state;
    return employee.map(name => < Link className = 'link'
      to = '/user' > < div key = {
        name.id
      }
      className = 'item' > < img className = 'img'
      src = {
        `https://picsum.photos/${name.name}`
      } > < /img> <h1 className='name'> {name.name} </h
      1 > < /div> </Link > )
  }

  render() {
    return ( <
      div className = 'body' > {
        this.getName()
      } <
      /div>
    )
  }
}


export default Body;

有人可以帮我吗？

刚开始，您没有正确设置路由器

App.js

import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'

class App extends React.Component {
  render () {
    return (
      <Router>
        <Home>
          <Switch>
            <Route path='/user/:token' component={Body} />
          </Switch>
        </Home>
      </Router>
    )
  }
}

Home.js-现在您将路由器包装在儿童中

class Home extends React.Component {
  render () {
    return (<div className='home' >
      <Header />
      {this.props.children} {/* This line will render router children which will be Body */}
    </div>
    )
  }
}

Body.js

现在您会收到体内的东西，this.props.match.params我想您会自己弄清楚的
