import * as React from "react";
export default class App extends React.Component {
    constructor(props) {
        super(props)
        this.state = {
            data: ''
        };
    }

    componentDidMount() {
        let self = this;
        fetch('http://blog.domain.com/admin.php')
            .then(function (response) {
                return response.text()
            }).then(function (text) {
            console.log(text)
            self.setState({
                data: text
            });
        })
    }

    render() {
        return (<div dangerouslySetInnerHTML={{__html: this.state.data}}></div>
        );
    }
}
