How can I pass data using <Redirect> in react router v4?

Question

The situation is that I use axios gain data from back-end and I want to redirect from current page to another page as well as passing some data.

How can I pass data when I use <Redirect> to redirect?

I am using code like below, and I can't get 'profile' at the destination page. No matter, this.props or this.state

I understand that using react-router-redux is a better choice.

import React, { Component } from 'react'
import axios from 'axios'
import { Redirect } from 'react-router'

export default class Login extends Component {
    constructor(props) {
        super(props)

        this.state = {
            email: '',
            emailError: 'Please fill in email',
            password: '',
            passwordError: 'Please fill in password',
            redirect: false,
            profile: ''
        }

        this.handleEmail = (e) => {
            var email = e.target.value
            var emailError = ''

            if (email === null)
                emailError = 'Please fill in email'

            this.setState({
                email: email,
                emailError: emailError
            })
        }

        this.handlePassword = (e) => {
            var password = e.target.value
            var passwordError = ''

            if (password === null)
                passwordError = 'Please fill in password'

            this.setState({
                password: password,
                passwordError: passwordError
            })
        }

        this.handleSubmit = (e) => {
            e.preventDefault()

            if (this.state.emailError)
                alert(this.state.emailError)
            else if (this.state.passwordError)
                alert(this.state.passwordError)
            else {
                axios.post('/user/login', {
                    email: this.state.email,
                    password: this.state.password
                }).then(response => {
                    if (response.data !== 'fail') {
                        this.setState({
                            redirect: true,
                            profile: response.data
                        })
                    }
                })
            }
        }
    }

    render() {
        const { redirect, profile } = this.state

        if (redirect)
            return (<Redirect to={{
                pathname: '/user/profile',
                state: { referrer: this.state.profile }
            }} />)

        return (
            <div className="content user">
                <div className="container">
                    <div className="row">

The way you are passing your state to the Redirect is correct, the only place the problem should be is how you are accessing it. State can be accessed like this.props.location.state. However if you directly route to the path then state won't we available so you need to add a check

Access your state like

 this.props.location.state && this.props.location.state.referrer
