javascript - react 路由器 goBack() 无法正常工作

Question

我遇到了一个问题。我使用 react-router-dom 进行路由。它运行良好，但 goBack 无法正常运行。当我单击返回按钮时，它第一次转到 NotFound/Signin页面然后重定向到后页。我该如何克服这个问题？

import React from 'react';
import { Router, Route, Switch } from 'react-router-dom';
import createBrowserHistory from 'history/createBrowserHistory';

import Signin from '../ui/signin/Signin';
import AddEvent from '../ui/events/AddEvent';
import EventView from '../ui/events/EventView';
import NotFound from '../ui/NotFound';

const history = createBrowserHistory();
const privatePages = [
    '/events', 
    '/addevent',

];
const publicPages = ['/', '/signup','/forgotpassword'];

const onEnterPublicPage = () => {
    if (Meteor.userId()) {
        history.replace('/events');
    }
};

const onEnterPrivatePage = () => {
    if (!Meteor.userId()) {
        history.replace('/');
    }
};

export const onAuthenticationChange = (isAuthenticated) => {

    const pathname = this.location.pathname;
    const isUnauthenticatedPage = publicPages.includes(pathname);
    const isAuthenticatedPage = privatePages.includes(pathname);

    if (isAuthenticated && isUnauthenticatedPage) {
        history.replace('/events');
    } else if (!isAuthenticated && isAuthenticatedPage) {
        history.replace('/');
    }
}

export const routes = (
    <Router history = {history}>
        <Switch>
            <Route 
            exact path="/events" 
            component={ListEvents} 
            onEnter={onEnterPrivatePage} />

            <Route 
            exact path="/addevent" 
            component={AddEvent} 
            onEnter={onEnterPrivatePage} />

            <Route  component={NotFound}/>

            <Route 
            exact path="/" 
            component={Signin} 
            onEnter={onEnterPublicPage} />

        </Switch>
    </Router>
);

在组件中:

constructor(props){
        super(props);
        this.goBack = this.goBack.bind(this);
    }

    goBack(){
        this.props.history.goBack();
        //  this.props.history.push.go(-1);
    }

在返回

<Link
    to="" 
    onClick={this.goBack}
    className="back-icon">
    Back
</Link>

这是因为您使用的是 history.replace('/') .您正在更换，而不是插入，因此没有以前的路线。
