Private Channel

Login (private channel authentication)

Authentication process : establish connection → send login request → wait for response → subscribe to private channel

Login request :

{
  "op": "login",
  "args": [
    {
      "apiKey": "YOUR_API_KEY",
      "timestamp": "1766124407915",
      "sign": "BASE64_ENCODED_SIGNATURE"
    }
  ]
}

Request parameters :

Parameter	Type	Explanation
apiKey	String	API Key
timestamp	String	Current timestamp (milliseconds)
sign	String	Signature (Base64 encoding)

Signature generation :

Signature string: timestamp + "GET" + "/user/verify" + ""

Use secretKey to encrypt the signature string with HMAC SHA256
Base64 encoding the results

JavaScript example :

const crypto = require('crypto');
function generateSign(timestamp, secretKey) {
    const message = timestamp + 'GET' + '/user/verify' + '';
    return crypto.createHmac('sha256', secretKey).update(message).digest('base64');
}

Python example :

import hmac, base64

def generate_sign(timestamp, secret_key):
    message = timestamp + 'GET' + '/user/verify' + ''
    signature = hmac.new(bytes(secret_key, 'utf8'), bytes(message, 'utf-8'), digestmod='sha256').digest()
    return base64.b64encode(signature).decode()

Login response :

{"event": "login","code": "0"}
