    static defaultProps = {
        title: '您好'
    }
    constructor(props: IProps) {
        super(props)
        this.state = {
            date: '2020-02-09'
        }
    }

    render() {
        const { date } = this.state

        return (
            <div>
                <p>{ date }</p>
                <p>{this.props.title}</p>
            </div>
