我有一个小应用程序,可以在开发模式下使用webpack-dev-server正常工作,但是当我使用生产模式生成的dist文件夹中的捆绑文件时,在浏览器中看到的只是这个错误:>
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'.
如何解决这个pushState问题?
由于webpack抛出此错误,最初我尝试使用React.lazy和Suspense拆分代码:
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.
但是问题仍然存在。
您可以在此处查看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>
);
我想从生产模式所产生的捆绑文件中获得与开发模式相同的结果。

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

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';
具有:
import { HashRouter, Route, Link, Switch } from 'react-router-dom';
或:
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,一切应该像使用localhost / dev服务器一样工作。

我有此错误(尽管在我的react应用程序中),因为我提供了而不是searchParams url ,而是将整个URL放入了history.pushState http://localhost:9090/admin/model-type?PageNumber=2
但搜索查询应为?PageNumber=2
history.pushState(
{[paramKey]: paramValue},
'page title',
url
)
