在当前版本的React Router (v3)中，我可以接受服务器响应并使用browserHistory。点击进入相应的响应页面。但是，这在v4中是不可用的，我不确定处理它的适当方法是什么。
在这个例子中，使用Redux, components/app-product-form.js在用户提交表单时调用this.props. addproduct (props)。当服务器返回成功时，用户将被带到Cart页面。
// actions/index.js
export function addProduct(props) {
return dispatch =>
axios.post(`${ROOT_URL}/cart`, props, config)
.then(response => {
dispatch({ type: types.AUTH_USER });
localStorage.setItem('token', response.data.token);
browserHistory.push('/cart'); // no longer in React Router V4
});
}
如何从React Router v4的函数重定向到购物车页面?
创建一个带有自己的browserHistory的自定义路由器:
import React from 'react';
import { Router } from 'react-router-dom';
import { createBrowserHistory } from 'history';
export const history = createBrowserHistory();
const ExtBrowserRouter = ({children}) => (
<Router history={history} >
{ children }
</Router>
);
export default ExtBrowserRouter
接下来，在你定义路由器的根目录上，使用以下命令:
import React from 'react';
import { /*BrowserRouter,*/ Route, Switch, Redirect } from 'react-router-dom';
//Use 'ExtBrowserRouter' instead of 'BrowserRouter'
import ExtBrowserRouter from './ExtBrowserRouter';
...
export default class Root extends React.Component {
render() {
return (
<Provider store={store}>
<ExtBrowserRouter>
<Switch>
...
<Route path="/login" component={Login} />
...
</Switch>
</ExtBrowserRouter>
</Provider>
)
}
}
最后，在需要的地方导入历史记录并使用它:
import { history } from '../routers/ExtBrowserRouter';
...
export function logout(){
clearTokens();
history.push('/login'); //WORKS AS EXPECTED!
return Promise.reject('Refresh token has expired');
}
如果你正在使用Redux，那么我建议使用npm包react-router-redux。它允许您分派Redux存储导航操作。
你必须在他们的自述文件中创建存储。
最简单的用例:
import { push } from 'react-router-redux'
this.props.dispatch(push('/second page'));
容器/组件的第二个用例:
容器:
import { connect } from 'react-redux';
import { push } from 'react-router-redux';
import Form from '../components/Form';
const mapDispatchToProps = dispatch => ({
changeUrl: url => dispatch(push(url)),
});
export default connect(null, mapDispatchToProps)(Form);
组件:
import React, { Component } from 'react';
import PropTypes from 'prop-types';
export default class Form extends Component {
handleClick = () => {
this.props.changeUrl('/secondPage');
};
render() {
return (
<div>
<button onClick={this.handleClick}/>
</div>Readme file
);
}
}
React Router 4中最简单的方法是使用
this.props.history.push('/new/url');
但是要使用此方法，您现有的组件应该能够访问历史对象。我们可以通过
If your component is linked to Route directly, then your component already has access to history object.
eg:
<Route path="/profile" component={ViewProfile}/>
Here ViewProfile has access to history.
If not connected to Route directly.
eg:
<Route path="/users" render={() => <ViewUsers/>}
Then we have to use withRouter, a heigher order fuction to warp the existing component.
Inside ViewUsers component
import { withRouter } from 'react-router-dom';
export default withRouter(ViewUsers);
That's it now, your ViewUsers component has access to history object.
更新
2-在这个场景中，将所有的路由道具传递给你的组件，然后我们可以从组件中访问this.props.history，即使没有一个HOC
eg:
<Route path="/users" render={props => <ViewUsers {...props} />}

<Router history={history} >
{ children }
</Router>
);
export default ExtBrowserRouter

export default class Root extends React.Component {
render() {
return (

<ExtBrowserRouter>
<Switch>
...
<Route path="/login" component={Login} />
...
</Switch>
</ExtBrowserRouter>
</Provider>
)
}
}
