reactjs - 重新加载 React Router 应用程序时出现 404 错误

Question

当我在本地服务器上重新加载我的应用程序时，一切正常。但是当我在 gh-pages 上托管时重新加载页面时，我收到 404 错误。它不会在主页上执行此操作，但会在其他 2 个页面上执行此操作。它与它被远程托管的事实有关吗？我对 React Router 有点菜鸟。任何帮助将不胜感激。这是相关代码和下面我的应用程序的链接:

React Game App

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

class App extends Component {
  render() {
    return (
      <Router>
        <div className="App">
          <Nav />
          <div className="container">
            <Switch>
              <Route exact path="/react-game-search" component={MainPage} />
              <Route path="/games" component={GameSearch} />
              <Route  path="/about" component={About} />}
              <Route  path="/details" component={GamesDetails} />}
            </Switch>
          </div>
        </div>
      </Router>
    );
  }
}

const Nav = () => {
  return (
    <div className="navbar">
      <div className="navbar-item">
        <NavLink
          exact to="/react-game-search/"
          activeClassName="selected"
          className="nav-link"
        >Home</NavLink>
      </div>
      <div className="navbar-item">
        <NavLink
           to="/games"
          activeClassName="selected"
          className="nav-link"
        >Games</NavLink>
      </div>
      <div className="navbar-item">
        <NavLink
           to="/about"
          activeClassName="selected"
          className="nav-link"
        >About</NavLink>
      </div>
    </div>
  );
}

class Game extends Component {

  addDefaultSrc = (ev) => {
    ev.target.src = errorIcon;
  }

  render() {
    const { icon, gameTitle, game } = this.props;
    return (
      <div className="game-box">
        <Link
          style={{ textDecoration: 'none' }}
          to={{
            pathname: "/details",
            state: { game }
          }}>
          <div className="game-content">
            <img className="game-icon" onError={this.addDefaultSrc} src={icon} alt="icon" />

            <p className="game-link"><strong>{gameTitle}</strong></p>

          </div>
        </Link>
      </div>
    );
  }

}

ReactDOM.render(<App />, document.getElementById('root'));

Answer 1

那是因为当您重新加载页面时，它会尝试访问 /games 页面。但是在github页面上，只有/或者/index.html页面。所以，您收到 404 错误。

您可能会发现此答案有帮助:https://github.com/facebook/create-react-app/issues/1765#issuecomment-285114194

从那里:

Two solutions:

Don’t use HTML5 history on GitHub pages. Use hashHistory instead. Your URLs will look like https://rockchalkwushock.github.io/rcws-development/#path/inside/the/app.

Use process.env.PUBLIC_URL in your route definitions so that they work both in development and after deployment. For example: . This will be empty in development and rcws-development (inferred from homepage) in production.

我建议切换到散列导航策略，这样您的路线将看起来像 blabla.com/#game 而不是 blabla.com/game。它会将所有请求路由到您的 index.html，因此您可以使用 React 处理路由。
