javascript - cex.io web socket认证时间戳错误

Question

我目前正在尝试连接到 CEX.IO 比特币交易所的 websocket。 Websocket 连接正常，但在身份验证时出现错误:时间戳不在 20 秒范围内。我不知道这是什么错误。

createSignature 的测试用例 1 和 2 正常 (https://cex.io/websocket-api#authentication)。

计算签名和请求参数的代码

const WebSocket = require('ws');
const cexioWs = new WebSocket(
    'wss://ws.cex.io/ws/',
    {
        perMessageDeflate: false
    }
);
function createAuthRequest(apiKey, apiSecret) {
    let curTime = Math.floor(Date.now() / 1000);
    let hmac = crypto.createHmac('sha256', apiSecret);
    hmac.update(curTime.toString());
    hmac.update(apiKey);
    let args =
        {
            e: "auth",
            auth: {
                key: apiKey,
                signature: hmac.digest('hex'), //createSignature(curTime, apiKey, apiSecret),
                timestamp: curTime
            }
        };
    let authMessage = JSON.stringify(args);
    console.log(args);
    return authMessage;
}
cexioWs.on('message', (mess, error) => {
    //console.log("connected");
    console.log("cexio message");
    console.log(mess);
    let JSONMess = JSON.parse(mess);
    if (JSONMess.e === "connected") {
        cexioWs.send(createAuthRequest(key, secret));
        cexioWs.send(JSON.stringify({
            e: "subscribe",
            roomss: [
                "tickers"
            ]
        }));
    }
    if (JSONMess.e === "ping") {
        console.log("pong message");
        cexioWs.send(JSON.stringify({e: "pong"}));
    }
});

Answer 1

这是工作代码:

const crypto = require('crypto')
const WebSocket = require('ws')

var apiKey = ''
var apiSecret = ''

const cexioWs = new WebSocket('wss://ws.cex.io/ws/', {perMessageDeflate: false });

function createSignature(timestamp, apiKey, apiSecret){ 
    var hmac = crypto.createHmac('sha256', apiSecret );
    hmac.update( timestamp + apiKey );
    return hmac.digest('hex');
}

function createAuthRequest(apiKey, apiSecret ){
    var timestamp = Math.floor(Date.now() / 1000);
    var args = { e: 'auth', auth: { key: apiKey,
        signature: createSignature(timestamp, apiKey, apiSecret), timestamp: timestamp } };
    var authMessage = JSON.stringify( args );
    return authMessage;
}

cexioWs.on('message', (mess, error) => {
        console.log("cexio message");
        console.log(mess);
    let JSONMess = JSON.parse(mess);
    if (JSONMess.e === "connected") {
        cexioWs.send(createAuthRequest(apiKey, apiSecret));
        cexioWs.send(JSON.stringify({
            e: "subscribe",
            rooms: [
                "tickers"
            ]
        }));
    }
    if (JSONMess.e === "ping") {
        console.log("pong message");
        cexioWs.send(JSON.stringify({e: "pong"}));
    }
});
