反应路由器更改 URL，但视图没有改变，但是如果我在 url 位于浏览器选项卡上时按 Enter

Question

I have a page that renders a list of users, each user is a link that get's the user details. My list displays well, when i click a user the url changes but the view don't, but if i press enter again on that url the view changes to the details of that user, and after this when i am in the details page if i press the users list button in my layout the url changes but nothing happens again.

I have tried some solutions that i saw similar but no success

Users.js

import React from "react"
import { BrowserRouter as Router, Route, withRouter,Switch} from "react-router-dom"
import Layout from "../components/layout"
import User from "../components/users"
import MainComponentWrapper from "../components/mainComponentWrapper"
import UserDetails from "../components/userDetails"

const roleWrapper = props => {
  const url = "http://localhost:5000/user/" + props.match.params.cn
  return (
    <MainComponentWrapper url={url}>
      <UserDetails />
    </MainComponentWrapper>
  )
}

const IndexPage = () => (

export default IndexPage

export default function User({ data })  {
  const classes = useStyles()

  return (

    <div className={classes.root} >

    <Router>
      <div>
         <Switch>
               <Route exact path="/users/:cn"  component={roleWrapper} />
               <Route exact path="/users" component={User}>
                    <MainComponentWrapper url="http://localhost:5000/user">
                         <User />
                     </MainComponentWrapper>
                 </Route>

           </Switch>

       </div>
    </Router>

Move both routes as children in the switch component, and add the exact prop in route component.

I think you need to wrap the component inside withRouter HOC , you can do this

const IndexPage = () => (
  <Layout>
  <Router>
    <div>
     <Switch>
           <Route exact path="/users" component={withRouter(User)}>
                <MainComponentWrapper url="http://localhost:5000/user">
                     <User />
                 </MainComponentWrapper>
             </Route>
       </Switch>
            <Route path="/users/:cn"  component={withRouter(roleWrapper)} />
    </div>
  </Router>
  </Layout> )

Also the component name should start with a Capital letter

Hope it helps
