React Router V4 Redirect after form submission

ContactForm.js

import React, { Component } from 'react';

import { withRouter } from 'react-router-dom'; // <--- import `withRouter`. We will use this in the bottom of our file.

class ContactForm extends Component {

  submitForm (e) {
    e.preventDefault()
    this.props.history.push('/thank-you'); // <--- The page you want to redirect your user to.
  }

  render() {
    return (
      <div>
        <form onSubmit={this.submitForm.bind(this)}>
          <button type="submit">Submit</button>
        </form>
      </div>
    );
  }
}

export default withRouter(ContactForm); // <--- make sure to wrap your component with `withRouter()`

Thank you so much!

thank you. :)
I needed this :
this.props.history.push('/thank-you'); // <--- The page you want to redirect your user to.

When I try to use this example I keep getting Invariant Violation: You should not use <Route> or withRouter() outside a <Router>.

Code:

import React from 'react';
import ReactDOM, { render } from 'react-dom';
import PropTypes from 'prop-types';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import { graphql } from 'react-apollo';
import { withRouter } from 'react-router-dom';
import gql from 'graphql-tag';
import registerQuery from './RegisterQuery';
import s from './Register.css';

let postURL;

class Register extends React.Component {

  constructor() {
    super();
    this.state = {
      schoolName: '',
      userName: '',
      password: ''
    };
    this.onSchoolNameChange = this.onSchoolNameChange.bind(this);
    this.onUserNameChange = this.onUserNameChange.bind(this);
    this.onPasswordChange = this.onPasswordChange.bind(this);
  }

  componentDidMount() {
    postURL = `${global.location.origin}/graphql`;
  }

  onSchoolNameChange(event) {
    this.setState({ schoolName: event.target.value });
  }

  onUserNameChange(event) {
    this.setState({ userName: event.target.value });
  }

  onPasswordChange(event) {
    this.setState({ password: event.target.value });
  }

  handleSubmit(data) {
    e.preventDefault();
    this.props.history.push('/login');
  }

  render() {
    console.log(this.props);
    const { schoolName, userName, password } = this.state;
    const isEnabled = schoolName.length > 0 && userName.length > 0 && password.length > 0;
    return (
      <div className={s.root}>

        </div>
      </div>
    );
  }
}

export default graphql(registerQuery)(withStyles(s)(withRouter(Register)));
