如何修复未捕获的DOMException：无法在“历史记录”上执行'pushState'

Question

我有这个小应用程序在开发模式下使用webpack-dev-server工作正常，但是当我使用生产模式生成的dist文件夹中的捆绑文件时，我在浏览器中得到的就是这个错误：

Uncaught DOMException: Failed to execute 'pushState' on 'History': A history state object with URL 'file:///C:/' cannot be created in a document with origin 'null' and URL 'file:///C:/Users/cristi/work/react_test_ground/dist/index.html'.

我该如何解决这个pushState问题？

最初我试图用React.lazy和Suspense拆分代码，因为webpack抛出了这个错误：

WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
Assets:
  2c7b7b6becb423b8f2ae.bundle.js (413 KiB)

WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
Entrypoints:
  main (413 KiB)
      2c7b7b6becb423b8f2ae.bundle.js


WARNING in webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of
your application.

但问题仍然存在。

你可以在这里看到代码和完整的存储库：https://github.com/cristiAndreiTarasi/temporary

App.js

import React, { Fragment, Suspense, lazy } from 'react';
import { BrowserRouter, Route, Link, Switch } from 'react-router-dom';

const Home = lazy(() => import('./Home'));
const Blog = lazy(() => import('./Blog'));
const Contact = lazy(() => import('./Contact'));

export default () => (
    <BrowserRouter>
        <div>
            <ul>
                <li><Link to='/'>Home</Link></li>
                <li><Link to='/blog'>Blog</Link></li>
                <li><Link to='/contact'>Contact</Link></li>
            </ul>

            <Suspense fallback={<p>Loading...</p>}>
                <Switch>
                    <Route exact path='/' component={Home} />
                    <Route path='/blog' component={Blog} />
                    <Route path='/contact' component={Contact} />
                </Switch>
            </Suspense>
        </div>
    </BrowserRouter>   
);

其他组件的格式如下：

import React from 'react';

export default () => (
    <div>
        <h1>Hello from the Blog</h1>
        <img src='../images/landscape-art_large.jpg' />
    </div>
);

我希望从生产模式生成的捆绑文件中获得与开发模式相同的结果。

Answer 1

您应该通过Web服务器打开文件。因为您无法在文件中更改位置历史记录：// api。

Answer 2

您可以使用HashRouter或MemoryRouter代替BrowserRouter。

只需替换此行：

import { BrowserRouter, Route, Link, Switch } from 'react-router-dom';

有：

import { HashRouter, Route, Link, Switch } from 'react-router-dom';

或者：

import { MemoryRouter, Route, Link, Switch } from 'react-router-dom';

然后在浏览器中打开您构建的index.html文件，一切都应该像使用localhost / dev服务器一样工作。
