解决：Warning: Hash history cannot PUSH the same path; a new entry will not be adde

//link.js
import React from 'react';
import {Route, Link as ReactRouterLink} from 'react-router-dom';
import {createPath} from 'history';

const Link = ({to, replace, ...props}) => (
    <Route path={typeof to === 'string' ? to : createPath(to)} exact>
        {({match}) => (
            <ReactRouterLink {...props} to={to} replace={replace || !!match} />
        )}
    </Route>
);

Link.propTypes = ReactRouterLink.propTypes;
Link.defaultProps = ReactRouterLink.defaultProps;

export default Link;

使用：

import Link from './link'; // use the custom Link component instead of the react-router Link

const App = () => {
    <ul>
        <li><Link to={{ pathname: '/one', search: 'foo=bar' }}>one</Link></li>
        <li><Link to="/two">two</Link></li>
    </ul>
}
