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?


当前回答

在这种情况下,你将道具传递给你的坦克。所以你可以简单地打电话

props.history.push('/cart')

如果情况并非如此,您仍然可以从组件传递历史记录

export function addProduct(data, history) {
  return dispatch => {
    axios.post('/url', data).then((response) => {
      dispatch({ type: types.AUTH_USER })
      history.push('/cart')
    })
  }
}

其他回答

React Router v4与v3(以及更早的版本)有本质上的不同,你不能像以前那样执行browserHistory.push()。

如果你想了解更多信息,这个讨论似乎是相关的:

创建一个新的browserHistory将不起作用,因为<BrowserRouter>创建了自己的历史实例,并侦听其上的更改。因此,不同的实例将更改url,但不更新<BrowserRouter>。 react-router不会在v4中公开browserHistory,只会在v2中公开。


相反,你有几个选择来做到这一点:

Use the withRouter high-order component Instead you should use the withRouter high order component, and wrap that to the component that will push to history. For example: import React from "react"; import { withRouter } from "react-router-dom"; class MyComponent extends React.Component { ... myFunction() { this.props.history.push("/some/Path"); } ... } export default withRouter(MyComponent); Check out the official documentation for more info: You can get access to the history object’s properties and the closest <Route>'s match via the withRouter higher-order component. withRouter will re-render its component every time the route changes with the same props as <Route> render props: { match, location, history }.


Use the context API Using the context might be one of the easiest solutions, but being an experimental API it is unstable and unsupported. Use it only when everything else fails. Here's an example: import React from "react"; import PropTypes from "prop-types"; class MyComponent extends React.Component { static contextTypes = { router: PropTypes.object } constructor(props, context) { super(props, context); } ... myFunction() { this.context.router.history.push("/some/Path"); } ... } Have a look at the official documentation on context: If you want your application to be stable, don't use context. It is an experimental API and it is likely to break in future releases of React. If you insist on using context despite these warnings, try to isolate your use of context to a small area and avoid using the context API directly when possible so that it's easier to upgrade when the API changes.

由于react router 5中已经包含了一个历史记录,因此我们可以通过参考访问相同的历史记录

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

function App() {
   const routerRef = React.useRef();
   const onProductNav = () => {
       const history = routerRef.current.history;
       history.push("product");
   }
return (
    <BrowserRouter ref={routerRef}>
        <Switch>
            <Route path="/product">
                <ProductComponent />
            </Route>
            <Route path="/">
                <HomeComponent />
            </Route>
        </Switch>
    </BrowserRouter>
)
}

我是这样做的:

import React, {Component} from 'react';

export default class Link extends Component {
    constructor(props) {
        super(props);
        this.onLogout = this.onLogout.bind(this);
    }
    onLogout() {
        this.props.history.push('/');
    }
    render() {
        return (
            <div>
                <h1>Your Links</h1>
                <button onClick={this.onLogout}>Logout</button>
            </div>
        );
    }
}

使用this.props.history.push(' /购物车');重定向到购物车页面,它将被保存在历史对象。

享受,迈克尔。

我再提供一个解决方案,以防它对其他人有用。

我有一个history.js文件,其中我有以下内容:

import createHistory from 'history/createBrowserHistory'
const history = createHistory()
history.pushLater = (...args) => setImmediate(() => history.push(...args))
export default history

接下来,在我定义路由器的根目录上,我使用以下命令:

import history from '../history'
import { Provider } from 'react-redux'
import { Router, Route, Switch } from 'react-router-dom'

export default class Root extends React.Component {
  render() {
    return (
     <Provider store={store}>
      <Router history={history}>
       <Switch>
        ...
       </Switch>
      </Router>
     </Provider>
    )
   }
  }

最后,在我的actions.js中,我导入历史并使用pushLater

import history from './history'
export const login = createAction(
...
history.pushLater({ pathname: PATH_REDIRECT_LOGIN })
...)

这样,我可以在API调用之后推送到新的操作。

希望能有所帮助!

This.context.history.push将不起作用。

我设法让推工作如下:

static contextTypes = {
    router: PropTypes.object
}

handleSubmit(e) {
    e.preventDefault();

    if (this.props.auth.success) {
        this.context.router.history.push("/some/Path")
    }

}
