只需使用useNavigate，即可使用最新版本的react

新文件.js

import { useNavigate } from "react-router-dom";

const Newfile = () => {
    const navigate = useNavigate();
   
    ....

    navigate("yourdesiredlocation");

    ....
}

export default Newfile;

在代码中使用上述的useNavigate功能。

要以编程方式进行导航，您需要将新的历史推送到组件中的props.history，这样就可以完成以下工作：

//using ES6
import React from 'react';

class App extends React.Component {

  constructor(props) {
    super(props)
    this.handleClick = this.handleClick.bind(this)
  }

  handleClick(e) {
    e.preventDefault()
    /* Look at here, you can add it here */
    this.props.history.push('/redirected');
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick}>
          Redirect!!!
        </button>
      </div>
    )
  }
}

export default App;

警告：此答案仅涵盖1.0之前的ReactRouter版本之后，我将用1.0.0-rc1用例更新这个答案！

你也可以在没有混合的情况下这样做。

let Authentication = React.createClass({
  contextTypes: {
    router: React.PropTypes.func
  },
  handleClick(e) {
    e.preventDefault();
    this.context.router.transitionTo('/');
  },
  render(){
    return (<div onClick={this.handleClick}>Click me!</div>);
  }
});

有上下文的问题是，除非在类上定义contextType，否则它是不可访问的。

至于什么是上下文，它是一个对象，就像props一样，从父对象传递给子对象，但它是隐式传递的，不需要每次都重新声明props。看见https://www.tildedave.com/2014/11/15/introduction-to-contexts-in-react-js.html

在React Router v4中，我遵循这两种方式以编程方式进行路由。

this.props.history.push（“/某物/某物”）this.props.history.replace（“/ssomething/something”）

第二个

替换历史堆栈上的当前条目

要获取道具中的历史记录，您可能必须使用

带路由器

InReact路由器v6

import { useNavigate } from "react-router-dom";

function Invoices() {
  let navigate = useNavigate();
  return (
    <div>
      <NewInvoiceForm
        onSubmit={async event => {
          let newInvoice = await createInvoice(event.target);
          navigate(`/invoices/${newInvoice.id}`);
        }}
      />
    </div>
  );
}

React Router v6入门

React路由器v6

我已经有一段时间没有接触过React了，但我想感谢并强调Shimrit Snapir的以下评论：

在React Router 6.0上，<Redirect/>更改为<Navigator/>

React路由器V4

tl:dr；

if (navigate) {
  return <Redirect to="/" push={true} />
}

简单而声明性的答案是，需要将<Redirectto={URL}push={boolean}/>与setState（）结合使用

push：boolean-如果为true，重定向将向历史中推送一个新条目，而不是替换当前条目。

import { Redirect } from 'react-router'

class FooBar extends React.Component {
  state = {
    navigate: false
  }

  render() {
    const { navigate } = this.state

    // Here is the important part
    if (navigate) {
      return <Redirect to="/" push={true} />
    }
   // ^^^^^^^^^^^^^^^^^^^^^^^

    return (
      <div>
        <button onClick={() => this.setState({ navigate: true })}>
          Home
        </button>
      </div>
    )
  }
}

这里有一个完整的例子。在这里阅读更多信息。
