Nodejs websockets 客户端待定承诺 [英] Nodejs websockets client pending promise

问题描述

尝试使用承诺从作为 nodejs 客户端的 websocket 连接中捕获所有数据.脚本在收到所有消息和 console.logging 'Promise { <pending> 之前退出}'，我预计它会记录响应 #1 |再见'.

Trying to capture all the data from a websocket connection as a nodejs client using a promise. Script is exiting before all the messages are received and console.logging 'Promise { <pending> }', I expected it to log 'response #1 | goodbye'.

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);

推荐答案

为了记录 response #1 |再见 你需要等待它解决.

For it to log response #1 | goodbye you will need to wait for it to resolve.

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