How can i use param in path as prop react router dom v6

Question

I have a route <Route path="post/:id" element={<PostByIdPage />} />

How can i get param id as props in react router dom v6?

Here is my PostByIdPage component :

import React, { Component } from 'react';
import OneSecret from '../OneSecret';
import getSecretsPublic from '../../../action/getSecretsPublic';
import { connect } from 'react-redux';


export class index extends Component {

    constructor(props) {
        super(props);
        this.state = {
            secretPublic: {
                content: ''
            }
        }
        let id = decodeURI(window.location.pathname.substring(6));
        let params = {
            id: id
        }
        this.props.getSecretsPublic(params)
            .then(res =>{
                if (res.type === 'ERROR_MESSAGE') {
                    return;
                }
                this.setState({secretPublic: res.payload.data[0]})
            });
    }

    render() {
        return (
            <div>
                <OneSecret element={this.state.secretPublic} key={this.state.secretPublic.id} />
            </div>
        )
    }
}

export default connect(null, {getSecretsPublic})(index)

I'm using window.location.pathname and split to get param but i want to get params from props to re render() my component based in params

Answer 1

Little late to answer but you can achieve it easily. <this.props.match> will be available once you use {useParams} from react-router-dom but its a little tricky for class-based components. If using functional component, you have a choice of directly using {useParams} and props.match will be available. For Class-based components like your case, You can do this with High order component:

import { useParams } from 'react-router-dom';
export function withRouter(Children) {
  return (props) => {
    const match = { params: useParams() };
    return <Children {...props} match={match} />
  }
}
class PostByIdPage extends Component {
  render() {
    return (
      <div className="App">
         <h1>Page for {this.props.match.params.id}</h1>
      </div>
    );
  }
}
export default withRouter(PostByIdPage);

Now in you classbased component, You can access id as:

this.props.match.params.id

No more Error for ' this.props.match is undefined'

Answer 2

i think its the same as before you can use useParams() like this:

let { id } = useParams();

update:

<Route path= "third/:id"  element={Content}/>

this is my code to call to the component and this is the component:

 class Content extends Component {
    componentDidMount () {

        console.log( this.props.match.params.id );
    }
  render() {
    return (
      <div className="App">
         <h1>Third</h1>
      </div>

    );
  }
}
