基于React路由跳转的几种方式

history.push({pathname: '/personal', search: 'test=22222'})

import React from 'react'
import { useHistory } from 'react-router-dom'
export default ()=> {
	const history = useHistory()
	// 页面跳转方法
	history.push({pathname: '/personal', search: 'test=22222'})
	return 123
}

import React from 'react'
import { useLocation } from 'react-router-dom'
export default ()=> {
	const location = useLocation()
	// 页面跳转方法
	console.log(location, 'props')
	return 123
}

history.push({pathname: '/personal', state: {test: 'dashboard'}})

import React from 'react'
import { useHistory } from 'react-router-dom'
export default ()=> {
	const history = useHistory()
	// 页面跳转方法
	history.push({pathname: '/personal', state: { test: 'dashboard' }})
	return 123
}

import React from 'react'
import { useLocation } from 'react-router-dom'
export default ()=> {
	const location = useLocation()
	// 页面跳转方法
	console.log(location, 'props')
	return 123
}

import { Link } from “react-router-dom”

<Link to={
            { pathname: "/XXX", //xxx为跳转到的路径
              state: { title: this.state.exam.title, actionCode: this.state.exam.actionCode } 
            }
          } >切换考试科目 <i className="iconfont icon-jiantou"></i></Link>

componentDidMount() {
        console.log(this.props.location.state.XXX);   //xxx指state对象中的键名    
    }

function Fast(props) {
     ...
    useEffect(() => {
        console.log(props.location.state.XXX);//xxx指state对象中的键名
    })
}

<button onClick={()=>{this.props.history.push('/detail/88')}}>跳往详情页</button>`

//  react-router-dom是通过“/:”去匹配url传递的参数 ,即id获取到上面的url传过来的88
<Route exact path="/detail/:id" component={Detail}></Route>
//页面接收参数
componentDidMount(){
  console.log(this.props.match.params);
}

<button onClick={()=>{this.props.history.push({
    pathname: '/detail', //要跳转到的路径
    state: {  //参数地址栏不显示，刷新地址栏，参数不丢失
      id: 456
    }
  })}}>去详情页</button>

<Route exact path="/detail" component={Detail}></Route>
//页面接收参数
componentDidMount(){
    console.log(this.props.history.location.state);
}

<button onClick={()=>{this.props.history.push({
    pathname: '/detail', //要跳转到的路径
    query: {  
      id: 456
    }
  })}}>去详情页</button>

<Route exact path="/detail" component={Detail}></Route>
//页面接收参数
componentDidMount(){
    console.log(this.props.history.location.query);
}
