Node JS错误"Unexpected token"

Question

我想在Rullete上创建一个基本网站。我得到了代码和脚本。当我运行脚本时，我得到了这个错误。

[SyntaxError: Unexpected token <]
SyntaxError: Unexpected token <
    at Object.parse (native)
    at Request._callback (/var/www/html/Bot/BOT/site.js:63:16)
    at Request.self.callback (/root/node_modules/request/request.js:200:22)
    at emitTwo (events.js:100:13)
    at Request.emit (events.js:185:7)
    at Request.<anonymous> (/root/node_modules/request/request.js:1067:10)
    at emitOne (events.js:95:20)
    at Request.emit (events.js:182:7)
    at IncomingMessage.<anonymous> (/root/node_modules/request/request.js:988:12)
    at emitNone (events.js:85:20)

我不知道该怎么解决。有人能帮我吗？

Site.js

第59-107行

    load();
var prices;
request('http://backpack.tf/api/IGetMarketPrices/v1/?key=56fce4a5c4404545131c8fcf&compress=1&appid=730', function(error, response, body) {
    prices = JSON.parse(body);
    if(prices.response.success == 0) {
        logger.warn('Loaded fresh prices');
        if(fs.existsSync(__dirname + '/prices.txt')){
            prices = JSON.parse(fs.readFileSync(__dirname + '/prices.txt'));
            logger.warn('Prices loaded from cache');
        } else {
            logger.error('No prices in cache');
            process.exit(0);
        }
    } else {
        fs.writeFileSync('prices.txt', body);
        logger.trace('New prices loaded');
    }
});
updateHash();
function updateHash() {
    query('SELECT * FROM `hash` ORDER BY `id` DESC LIMIT 1', function(err, row) {
        if(err) {
            logger.error('Cant get the hash, stopping');
            logger.debug(err);
            process.exit(0);
            return;
        }
        if(row.length == 0) {
            logger.error('Wrong hash found, stopping');
            process.exit(0);
        } else {
            if(hash != row[0].hash) logger.warn('Loaded hash'+row[0].hash);
            hash = row[0].hash;
        }
    });
}
io.on('connection', function(socket) {
    var user = false;
    socket.on('hash', function(hash) {
        query('SELECT * FROM `users` WHERE `hash` = '+pool.escape(hash), function(err, row) {
            if((err) || (!row.length)) return socket.disconnect();
            user = row[0];
            users[user.steamid] = {
                socket: socket.id,
                balance: parseInt(row[0].balance)
            }

63号线是吗

Answer 1

看起来请求的主体是不可解析的json。进行

console.log(body)

检查中传递的数据

Answer 2

最后，您应该将Prices更改为list或将Prices更改为dictionary:

prices = [];

或

prices = {};
