react-router v6对比react-router v5

简述: 

　   1. react-router v6 原生支持typeScript ; 安装方法 npm install react-router-dom@6

　   2. react-router v5 原生不支持typeScript,  需要安装 @types/react-router-dom 来支持ts ;  安装方法  npm install react-router-dom@5

　   3. react-router v5 路由配置 :　<BrowserRouter /> + <Switch /> + <Route />

　   4. react-router v6 路由配置 :   <BrowserRouter /> + <Routes/ > + <Route />

　   5. react-router v5和react-router v6区别:  官方文档 v5=>v6的变化

常规简单路由配置Demo图:

　　1. react-router v5:   

　　　　 通过props注入来获取路由状态;   

　　　　 类组件: (HOC高阶组件) withRouter==>history, location, match;    可以使任意组件都具备这些属性

　　　　 函数式组件:  useHistory, useLocation, useParams, useRouteMatch  来搞定

　　2. react-router v6: 

　　　　 因为完全倒向函数式组件;  直接用 hooks就行,useLocation,useParams;    注意 useHistory改成了 useNavigate

拓展: 

 一 . react-router v5: 三种常用的跳转   和   获取url参数:  

 1.  HOC 高阶组件  withRouter 跳转传值通信  

import React, { Component } from 'react'

import { withRouter } from 'react-router-dom';
//3. HOC 高阶组件  withRouter 传值通信   


export class LoginPage extends Component {

    render () {
        console.log(this.props)
        const { history, match, location } = this.props
        console.log(match.params) // 获取上个页面的路由参数
        console.log(history, match, location)
        return (
            <>
                <h1 onClick={() => history.push('/')}>withRouter跳转55555{match.params.id}</h1>
                <h1 onClick={() => history.goBack()}>返回{match.params.id}</h1>
                <h1 onClick={() => history.goForward()}>前进{match.params.id}</h1>
            </>
        )
    }
}
export default withRouter(LoginPage)

 2.  hooks 跳转页面传值通信  　引入  import { useHistory, useLocation, useParams, useRouteMatch } from 'react-router-dom';

import { Button } from 'antd';
import { useHistory, useLocation, useParams, useRouteMatch } from 'react-router-dom';

export const HomePage = (props) => {
    const history = useHistory()
    const location = useLocation()
    const params = useParams()
    const routeMatch = useRouteMatch()
    console.log(history, location, params, routeMatch)
    return (
        <>
            <div style={{ marginTop: 100 }}>
                <Button type="primary" onClick={() => history.push(`login/111`)}>跳转登录</Button>
                <Button>跳转注册</Button>
            </div>

        </>
    )

}

import { Button } from 'antd';
import {Link } from 'react-router-dom';

export const HomePage = () => {return (
            <div style={{ marginTop: 100 }}>
                {/* 2. Link组件跳转页面 */}
                <Link to={`login/444`}>
                    <Button type="dashed">Link组件跳转</Button>
                </Link>
            </div>
    )
}

二 . react-router v6: 两种常用的跳转   和   获取url参数: 

 1.  useNavigate

import React from "react";
import styles from './Header.module.css'
import { Button } from 'antd'
import { useParams, useLocation, useNavigate } from "react-router-dom";

export const Header: React.FC = (id=0) => {

    const navigate = useNavigate() // 进行页面的处理
    const location = useLocation() // 当前路径信息,保存当前路由状态
    const params = useParams() // 获取url参数
    console.log(navigate, location, params)
return (
        <div className={styles['App-header']}>
            <div className={styles['App-header-box']}>
                    <Button.Group>
                        <Button onClick={() => navigate(`/login/${id}`)}>注册</Button>
                        <Button onClick={() => navigate('/register')}>登录</Button>
                    </Button.Group>
            </div>
        </div>
    )
}

　2. LInk

import React from "react";
import { Link } from 'react-router-dom'

export const ProductImage: React.FC<PropsType> = ({id=3, name }) => {
    return (
        <Link to={`/detail/${id}`}>
            xxxxxxx
        </Link>
    );
}
