关于react.js:react-路由传参及其区别

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

劣势 ： 刷新地址栏，参数仍然存在
毛病:只能传字符串，并且，如果传的值太多的话，url会变得长而俊俏。

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

劣势：传参优雅，传递参数可传对象；
毛病：刷新地址栏，参数失落

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

4.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中获取路由参数的形式：

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>
    )
}
