在React Router V4中,如何导航到定义的基本名称之外的页面?

考虑以下React Router V4代码:

const isAuthenticated = () => {
    let hasToken = localStorage.getItem("jwtToken");
    if (hasToken) return true;
    return false;
};

const AuthenticatedRoute = ({ component: Component, ...rest }) =>
    <Route
        {...rest}
        render={props =>
            isAuthenticated()
                ? <Component {...props} />
                : window.location = "/auth/login" } <<-- ERROR HERE
    />;

class App extends Component {
    render() {
        return (
            <BrowserRouter basename="/editor">
                <Switch>
                    <AuthenticatedRoute exact path="/" component={AppHome} />
                    <AuthenticatedRoute
                        exact
                        path="/:module"
                        component={AppNav}
                    />

                    <Route component={PageNotFound} />
                </Switch>
            </BrowserRouter>
        );
    }
}

export default App;

auth/login是需要从服务器加载的另一个ReactJs应用程序,换句话说,auth/login需要绕过客户端路由并发送到服务器,在那里它将被路由并将服务于新的ReactJS应用程序(auth应用程序与login页面)。

尝试重定向(未经过身份验证)时,我在浏览器控制台上收到以下错误:

You are attempting to use a basename on a page whose URL path does not begin with a basename. 
Expected path "/login" to begin with "/editor"

看起来我被“困在”React Router V4中,没有任何东西可以脱离基本名称。

如何解决这个问题并重定向到服务器页面,退出或绕过反应路由器本身?

您需要在应用中安装react-router-dom

yarn add react-router-dom


npm i -S react-router-dom

并导入此

import { BrowserRouter as Router } from 'react-router-dom';

您要重定向的位置

browserHistory.push('/path/some/where');

您的代码应

import { BrowserRouter as Router } from 'react-router-dom';

const isAuthenticated = () => {
    let hasToken = localStorage.getItem("jwtToken");
    if (hasToken) return true;
    return false;
};

    const AuthenticatedRoute = ({ component: Component, ...rest, history }) =>
        <Route
            {...rest}
            render={props =>
                isAuthenticated()
                    ? <Component {...props} />
                    : history.push("/auth/login")}
        />;
class App extends Component {
    render() {
        return (
            <BrowserRouter basename="/editor">
                <Switch>
                    <AuthenticatedRoute exact path="/" component={AppHome} />
                    <AuthenticatedRoute
                        exact
                        path="/:module"
                        component={AppNav}
                    />

                    <Route component={PageNotFound} />
                </Switch>
            </BrowserRouter>
        );
    }
}

export default App;

您应该使用Redirect

提供的react-router-dom组件
import { Redirect, Route } from 'react-router-dom';
const AuthenticatedRoute = ({ component: Component, ...rest }) =>
  <Route
    {...rest}
    render={props =>
      isAuthenticated()? <Component {...props} />
       : (
          <Redirect
            to={{ pathname: 'auth/login' }}
           />
       )
     }
   />

这是一个有效的example
