javascript - Nodejs websockets 客户端待处理 promise

Question

尝试使用 Promise 作为 Node.js 客户端从 WebSocket 连接捕获所有数据。在收到所有消息和 console.logging 'Promise { <pending> }' 之前脚本已退出，我预计它会记录“响应#1 |再见”。

const WebSocket = require('ws');
const ws = new WebSocket('wss:url');

let results = new Promise(function(resolve, reject) {
    ws.on('open', function open() {
      ws.send('hello');
    });
    let receivedResults = '';
    ws.on('message', function incoming(data) {
        if (data == 'goodbye') {
            receivedResults += ' | ' + data;
            resolve(result);
        } else {
            receivedResults = data;
        }
    });
});
console.log(results);

Answer 1

让它记录响应#1 |再见，您需要等待它解决。

results.then(data => console.log(data));
