关于react-router的hashhistory

Question

用react－router 的时候报这个warn：

bundle.js:22167 Warning: [react-router] Router no longer defaults the history prop to hash history. Please use the hashHistory singleton instead.

是不是说不支持直接写入hash格式的历史到浏览器历史中了？（感觉不是..
自己对这个错误理解的好像不是很对，想请有经验人士在帮助解释一下。

还有自己看Github上的示例有用到：

import useBasename from 'history/lib/useBasename'

// This helper is for setting basename on examples with minimal boilerplate. In
// an actual application, you would build a custom history to set basename.
export default function withExampleBasename(history, dirname) {
  return useBasename(() => history)({ basename: `/${dirname}` })
}

之后

render((
  <Router history={withExampleBasename(browserHistory, __dirname)}>
    <Route path="/" component={App}>
      <IndexRoute component={Index}/>
      <Route path="/about" component={About}/>
      <Route path="/users" component={Users}>
        <IndexRoute component={UsersIndex}/>
        <Route path=":id" component={User}/>
      </Route>
    </Route>
  </Router>
), document.getElementById('example'))

以前用history这个包的时候也没有这样用过，想请经验人士帮助解释一下，感激不尽！

Answer 1

  <Router history={withExampleBasename(browserHistory, __dirname)}>

改成

<Router hashHistory={withExampleBasename(browserHistory, __dirname)}>
