Как сделать запрос на сервер в React?

class App extends React.Component {
	constructor() {
		super();
		this.state = {value: ''};
	}

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

	handleSubmit(event) {
		alert(this.state.value); 
		event.preventDefault(); 
	}

	render() {
		return <form onSubmit={this.handleSubmit.bind(this)}>
                        <label>
                            Name:
			<input value={this.state.value} onChange={this.handleChange.bind(this)} />
                        </label>
			<input type="submit" />
		</form>
	}
}
