React router dom将数据从父组件传递到子路由器组件不传递props.match

父组件App.js的内容：-

import React, { useEffect, useState } from "react";
import NavBar from "./components/NavBar";
import Signup from "./pages/Signup";
import Home from "./pages/Home";
import Book from "./pages/Book";

function App() {
  const [user, setUser] = useState();
  useEffect(() => {
    const token = "Bearer " + sessionStorage.getItem("token");
    if (token) {
      axios
        .get(process.env.REACT_APP_API_URL + "user/self", {
          headers: {
            Authorization: token,
            "Content-Type": "application/json",
          },
        })
        .then((res) => setUser(res.data));
    }
  }, []);

  return (
    <div className="container-fluid">
      <NavBar user={user} />
      <Route exact path="/" component={Home} />
      <Route path="/signup" component={Signup} />
      <Route exact path="/book/:id" component={() => <Book user={user} />} />
    </div>
  );
}

export default App;

对于路线：-

<Route exact path="/book/:id" component={() => <Book user={user} />} />

当我将组件值从组件 = {Book} 设置为组件 = {() => 我收到错误:-

类型错误：无法读取未定义的属性“params”

那是因为我在 Book 组件中使用“props.match.params.id”。

如何将用户状态与 props.match 传递给 Book 组件？

这就是使用 component 属性的方式

<Route exact path="/book/:id" component={Book} />

考虑使用render道具而不是component像这样的道具：

<Route exact path="/book/:id" render={(routeProps) => <Book user={user} {...routeProps} />} />
