OKEX V5 WS接口私有接口使用范例，策略参数accessKey、secretKey、passphrase。其中passphrase是在交易所网站创建APIKEY时填写的秘钥口令。策略例子首先登陆验证，然后订阅了所有持仓信息。定时发送ping，交易所服务器会响应pong。
function getLogin(pAccessKey, pSecretKey, pPassphrase) {
// 签名函数，用于登录
var ts = (new Date().getTime() / 1000) + ""
var login = {
"op": "login",
"args":[{
"apiKey" : pAccessKey,
"passphrase" : pPassphrase,
"timestamp" : ts,
"sign" : exchange.HMAC("sha256", "base64", ts + "GET" + "/users/self/verify", pSecretKey)
}]
}
return login
}
var client_private = null
function main() {
// 因为read函数使用了超时设置，过滤超时的报错，否则会有冗余错误输出
SetErrorFilter("timeout")
// 持仓频道订阅信息
var posSubscribe = {
"op": "subscribe",
"args": [{
"channel": "positions",
"instType": "ANY"
}]
}
var payload = JSON.stringify(getLogin(accessKey, secretKey, passphrase))
client_private = Dial("wss://ws.okex.com:8443/ws/v5/private|reconnect=true&payload=" + payload)
Sleep(3000) // 登录时，不能立即订阅私有频道，需要等待服务器反应
if (client_private) {
client_private.write(JSON.stringify(posSubscribe))
var lastPingTS = new Date().getTime()
while (true) {
var buf = client_private.read(2000)
if (buf) {
Log(buf)
}
// 发送心跳包
var nowPingTS = new Date().getTime()
if (nowPingTS - lastPingTS > 10 * 1000) {
client_private.write("ping")
lastPingTS = nowPingTS
}
}
}
}
function onexit() {
var ret = client_private.close()
Log("关闭连接！", ret)
}
