我试着从YouTube教程中的代码将React应用程序从JavaScript转换为Typescript。

import 'swiper/swiper.min.css';
import './assets/boxicons-2.0.7/css/boxicons.min.css';
import './App.scss';
import { BrowserRouter, Route } from 'react-router-dom';
import Header from './components/header/Header';
import Footer from './components/footer/Footer';
import Routes from './config/Routes';

function App() {
  return (
    <BrowserRouter>
      <Route
        render={props => (
          <>
            <Header {...props} />
            <Routes />
            <Footer />
          </>
        )}
      />
    </BrowserRouter>
  );
}

export default App;

但我在此部分x1c 0d1x出错
这是我的标题代码

import { useRef, useEffect } from 'react';
import { Link, useLocation } from 'react-router-dom';
import './header.scss';
import logo from '../../assets/tmovie.png';

const headerNav = [
    {
        display: 'Home',
        path: '/'
    },
    {
        display: 'Movies',
        path: '/movie'
    },
    {
        display: 'TV Series',
        path: '/tv'
    }
];

const Header = () => {

    const { pathname } = useLocation();
    const headerRef:any = useRef(null);

    const active = headerNav.findIndex(e => e.path === pathname);

    useEffect(() => {
        const shrinkHeader = () => {
            if (document.body.scrollTop > 100 || document.documentElement.scrollTop > 100) {
                headerRef.current.classList.add('shrink');
            } else {
                headerRef.current.classList.remove('shrink');
            }
        }
        window.addEventListener('scroll', shrinkHeader);
        return () => {
            window.removeEventListener('scroll', shrinkHeader);
        };
    }, []);

    return (
        <div ref={headerRef} className="header">
            <div className="header__wrap container">
                <div className="logo">
                    <img src={logo} alt="" />
                    <Link to="/">tMovies</Link>
                </div>
                <ul className="header__nav">
                    {
                        headerNav.map((e, i) => (
                            <li key={i} className={`${i === active ? 'active' : ''}`}>
                                <Link to={e.path}>
                                    {e.display}
                                </Link>
                            </li>
                        ))
                    }
                </ul>
            </div>
        </div>
    );
}

export default Header;

如何在Typescript中使用Routerender prop?

您不能直接将...props作为属性传递给这里,因为这个文件和头组件之间存在类型不匹配,正如错误中提到的(history、location、match和staticContext)。你需要在header组件中设置正确的类型(例如,extend intrinsicAttributes),如:

interface HeaderProps extends React.HTMLAttributes<HTMLElement> {
  history: History<unknown>;
  location: Location<unknown>;
  match: match<{ [x: string]: string | undefined; }>;
  staticContext?: StaticContext | undefined;
}

function Header(props: HeaderProps) {
  ...
}

Header组件实际上并没有消耗任何props:

const Header = () => { // <-- NO PROPS
  const { pathname } = useLocation();
  const headerRef:any = useRef(null);

  const active = headerNav.findIndex(e => e.path === pathname);

  ...

Header正在使用React hook,取代了旧的route props,在本例中,特别是useLocation hook来访问以前的props.location prop值。使用React钩子现在是首选方法。
由于没有消耗 prop ,你应该清理路线,并删除路线 prop 的通过。

function App() {
  return (
    <BrowserRouter>
      <Route
        render={() => (
          <>
            <Header />
            <Routes />
            <Footer />
          </>
        )}
      />
    </BrowserRouter>
  );
}

或者作为一个小优化,直接渲染HeaderRoutesFooter,因为它们是通过无路径路由渲染的,而且无论如何都是无条件渲染的。

function App() {
  return (
    <BrowserRouter>
      <Header />
      <Routes />
      <Footer />
    </BrowserRouter>
  );
}
