Node Js Steam Trade 提供机器人物品

Question

此机器人接受所有交易，但它只需要接受在 itemsToReceive 中包含 [type: 'Consumer Grade SMG',] 项目的交易报价。我试图做类似的事情：如果 itemsToReceive 包含消费者级 SMG，则接受报价，否则取消报价，但我失败了。我是新手，我不知道该怎么做。 对不起我的英语不好。

我的输出控制台：

还有机器人代码：

/**
 * STOREHOUSE - node-steam
 * 
 * Uses node-steam-user for notifications and accepts all incoming trade offers
 */

var SteamUser = require('steam-user');
var TradeOfferManager = require('../lib/index.js'); // use require('steam-tradeoffer-manager') in production
var fs = require('fs');

var client = new SteamUser();
var 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
});

// Steam logon options
var logOnOptions = {
	"accountName": "xxxxx",
	"password": "xxxxx"
};

if(fs.existsSync('polldata.json')) {
	manager.pollData = JSON.parse(fs.readFileSync('polldata.json'));
}

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);
	});
});
manager.on('newOffer', function(offer) {
	console.log("New offer #" + offer.id + " from " + offer.partner.getSteam3RenderedID());
	console.log(offer.itemsToReceive);
	offer.accept(function(err) {
		if(err) {
			console.log("Unable to accept offer: " + err.message);
		} else {
			console.log("Offer accepted");
		}
	});
});

manager.on('receivedOfferChanged', function(offer, oldState) {
	console.log("Offer #" + offer.id + " changed: " + TradeOfferManager.getStateName(oldState) + " -> " + TradeOfferManager.getStateName(offer.state));
	
	if(offer.state == TradeOfferManager.ETradeOfferState.Accepted) {
		offer.getReceivedItems(function(err, items) {
			if(err) {
				console.log("Couldn't get received items: " + err);
			} else {
				var names = items.map(function(item) {
					return item.name;
				});
				
				console.log("Received: " + names.join(', '));
			}
		});
	}
});

manager.on('pollData', function(pollData) {
	fs.writeFile('polldata.json', JSON.stringify(pollData));
});

试试看。

manager.on('newOffer', function(offer) {
    console.log("New offer #" + offer.id + " from " + offer.partner.getSteam3RenderedID());
    console.log(offer.itemsToReceive);
    for(var i = 0; i > offer.itemsToReceive.length)
    {   
        if(offer.itemsToReceive[i]['type'] != "Consumer Grade SMG")
        {
            return;

            if(i == offer.itemsToReceive.length)
            {
                offer.accept(function(err){
                    if(err){
                        console.log("Unable to accept offer: " + err.message);
                    } 
                    else{
                        console.log("Offer accepted");
                    }
                });
            }
        }   
    }
});
