问如何将ReactJs中的数据发送到signalR？在Asp.net Mvc Web Api中

EN

public void SendMessageToAll(string userName, string message)
        {
             Clients.All.messageReceived(userName, message );

        }

import React, { Component } from 'react';
import { Link } from 'react-router-dom';
import { hubConnection } from 'signalr-no-jquery';


class Dashboard extends Component {
   constructor(props) {    
   super(props);
   const connection = hubConnection('https://localhost:44332');
   const hubProxy = connection.createHubProxy('Chat');

   hubProxy.on('Hello', function(name) {
    console.log(name);
});
    // atempt connection, and handle errors
    connection.start()

    .done(function(){ console.log('Now connected, connection ID=' + connection.id); })
    .fail(function(){ console.log('Could not connect'); });
}


  render() {
    return (
        <div/>
    );
  }
}

export default Dashboard;
