我可能得了老年痴呆，react-router的参数总是只知道params和query，每次炫技的时候总是会因为少记几种传参方式而显得有点铁憨憨，所以这次搞个文档记录下，嘻嘻
1.params
<Route path='/path/:name' component={Path}/>
<link to="/path/2">xxx</Link>
this.props.history.push({pathname:"/path/" + name})
读取参数用:this.props.match.params.name
优势 ： 刷新地址栏，参数依然存在
缺点:只能传字符串，并且，如果传的值太多的话，url会变得长而丑陋。
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2.query
<Route path='/query' component={Query}/>
<Link to={{ path : ' /query' , query : { name : 'sunny' }}}>
this.props.history.push({pathname:"/query",query: { name : 'sunny' }});
读取参数用: this.props.location.query.name
优势：传参优雅，传递参数可传对象；
缺点：刷新地址栏，参数丢失
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
3.state
<Route path='/sort ' component={Sort}/>
<Link to={{ path : ' /sort ' , state : { name : 'sunny' }}}>
this.props.history.push({pathname:"/sort ",state : { name : 'sunny' }});
读取参数用: this.props.location.query.state
优缺点同query
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
3.search
<Route path='/web/departManange ' component={DepartManange}/>
<link to="web/departManange?tenantId=12121212">xxx</Link>
this.props.history.push({pathname:"/web/departManange?tenantId" + row.tenantId})
读取参数用: this.props.location.search
优缺点同params
react Hooks中获取路由参数的方式：
1.通过hooks钩子函数
import { useHistory,useLocation,useParams,useMatch } from 'react-router-dom';
let history = useHistory();
history.push('/')
2.通过函数props参数
function Home(props) {
const location = useLocation();
return (
<div className='home'>
<Banner />
</div>
手懒的孩子只会复制粘贴。。
