Here is the documentation: https://github.com/DoctorMcKay/node-steam-tradeoffer-manager/wiki/TradeOfferManager#etradeofferstate
It is necessary that after the offer.state in ETradeOfferState [offer.state] was 9, display the console log
I tried this:
manager.on('ETradeOfferState[9]', function(offer) { console.log("123"); }); So:
manager.on('TradeOfferManager.ETradeOfferState[9]', function(offer) { console.log("123"); }); But does not work.
Full code:
const SteamUser = require('steam-user'); const SteamCommunity = require('steamcommunity'); const SteamTotp = require('steam-totp'); const TradeOfferManager = require('../lib/index.js'); // use require('steam- tradeoffer-manager') in production const FS = require('fs'); let client = new SteamUser(); let manager = new TradeOfferManager({ "steam": client, // Polling every 30 seconds is fine since we get notifications from Steam "domain": "example.com", // Our domain is example.com "language": "en" // We want English item descriptions }); let community = new SteamCommunity(); // Steam logon options let logOnOptions = { "accountName": "***************", "password": "***************", "twoFactorCode": SteamTotp.getAuthCode("") }; if (FS.existsSync('polldata.json')) { manager.pollData = JSON.parse(FS.readFileSync('polldata.json').toString('utf8')); } client.logOn(logOnOptions); client.on('loggedOn', function() { console.log("Logged into Steam"); }); client.on('webSession', function(sessionID, cookies) { manager.setCookies(cookies, function(err) { if (err) { console.log(err); process.exit(1); // Fatal error since we couldn't get our API key return; } console.log("Got API key: " + manager.apiKey); // Get our inventory manager.getInventoryContents(570, 2, true, function(err, inventory) { if (err) { console.log(err); return; } if (inventory.length == 0) { // Inventory empty console.log("CS:GO inventory is empty"); return; } console.log("Found " + inventory.length + " DOTA2 items"); }); }); community.setCookies(cookies); }); manager.on('sentOfferChanged', function(offer, oldState) { console.log(`Offer #${offer.id} changed: ${TradeOfferManager.ETradeOfferState[oldState]} -> ${TradeOfferManager.ETradeOfferState[offer.state]}`); }); manager.on('sentOfferChanged', function(offer, oldState) { console.log(`Offer #${offer.id} changed: ${TradeOfferManager.ETradeOfferState[oldState]} -> ${TradeOfferManager.ETradeOfferState[offer.state]}`); });
