每次发出事件时返回Promise

Question

嗨，大家好，每次发出事件时，我如何才能兑现承诺 代码如下：

    connect() {

        return new Promise( ( resolve, reject ) =>  {
                   this.wss.on( 'connection', ws => {
                         ws.on( 'message', ( message ) => {
                                log.debug( `Received <<  ${ message } `);
                                return resolve( {event: 'message', conn: ws, message: message} );
)} 
        ws.on( 'error', ( err ) => {
                        log.error( `Error on  ${ Utility.stringifyWebSocket(ws) } :   ${ err } ` );
                        return reject( {event: 'error', err: err} );
                    });                  

     });


conn.connect()
   .then( result => {
     connector.publish(message);
} )

我想在每次消息发送时发布消息，现在它只处理一条消息，返回仅被调用一次
