okex各账户（合约，币币，钱包）转币，有示例代码吗？
各交易所 子账户设置都不同，求 okex 示例 代码。
martinashes 请问币币账户向合约账户转账能通过API实现吗

发明者量化-小小梦 只要交易所提供有 转币 提币 等API 接口 ， 都可以用 exchange.IO 直接调用这些接口。 在数字货币交易类库 模板里有相关 代码 ，可以参看： ``` $.withdraw = function(e, currency, address, amount, fee, password) { var withdraw_id = null; var ret = null; currency = currency.toLowerCase() switch (e.GetName()) { case "OKCoin_EN": ret = e.IO("api", "POST", "/api/v1/withdraw.do", "symbol="+currency.toLowerCase()+"_usd&chargefee=" + fee + "&trade_pwd=" + password + "&withdraw_address=" + address + "&withdraw_amount=" + amount); if (ret && typeof(ret.withdraw_id) !== 'undefined') { withdraw_id = ret.withdraw_id; } else { var err = GetLastError(); if (err && err.indexOf('10031') !== -1) { Log("OKCoin_EN 需6个网络确认后方能提现"); } } break; case "Huobi": if (currency == "bch") { currency = "bcc" } ret = e.IO("api", "POST", "/v1/dw/withdraw-virtual/create", "currency="+currency+"&fee=" + fee + "&address=" + address + "&amount=" + amount); if (ret && typeof(ret.withdraw_id) !== 'undefined') { withdraw_id = ret.data; } break; case "Bithumb": ret = e.IO("api", "POST", "/trade/btc_withdrawal", "currency="+currency.toUpperCase()+"&address=" + address + "&units=" + amount); if (ret && parseInt(ret.status) == 0) { withdraw_id = 9999; } break; case "GateIO": ret = e.IO("api", "POST", "/api2/1/private/withdraw", "currency="+currency+"&address=" + address + "&amount=" + amount); if (ret && parseInt(ret.code) == 0) { withdraw_id = 9999; } break; case "ZB": ret = e.IO("api", "POST", "/api/withdraw", "method=withdraw&itransfer=0¤cy="+currency+"&receiveAddr=" + address + "&amount=" + amount+"&fees="+fee+"&safePwd="+password); if (ret && parseInt(ret.code) == 0) { withdraw_id = ret.id; } break; case "Bitfinex": var cMap = { "btc": "bitcoin", "ltc": "litecoin", "eth": "ethereum", "etc": "ethereumc", "zec": "zcash", "xmr": "monero", "omni": "mastercoin", "usd": "wire", "dash": "dash", "xrp": "ripple", "eos": "eos"}; if (typeof(cMap[currency]) == 'undefined') { throw "bitfinex not support " + currency; } var withdraw_type = cMap[currency]; ret = e.IO("api", "POST", "/v1/withdraw", "withdraw_type=" + withdraw_type + "&walletselected=exchange&address=" + address + "&amount='" + amount + "'"); if (ret && ret.length == 1 && typeof(ret[0].withdrawal_id) !== 'undefined') { withdraw_id = ret[0].withdrawal_id; } break; case "Poloniex": var ext = ""; if (currency == 'xrp') { //ext = '&paymentId=' + PXRPLabel; } if (currency.toLowerCase() == 'bts' && address.indexOf('_') == -1) { address = "poloniexwallet_" + address; } ret = e.IO("api", "POST", "withdraw", "amount=" + amount + "¤cy="+currency.toUpperCase()+"&address=" + address+ext); if (ret && ret.response.indexOf('With') !== -1) { withdraw_id = 9999; } break case "Bittrex": ret = e.IO("api", "GET", "/api/v1.1/account/withdraw", "quantity=" + amount + "¤cy="+currency.toUpperCase()+"&address=" + address); if (ret && ret.success) { withdraw_id = ret.result.uuid; } break case "Binance": ret = e.IO("api", "POST", "/wapi/v1/withdraw.html", "amount=" + amount + "&asset=" + currency + "&address=" + address); if (ret && ret.success) { withdraw_id = 9999; } break case "OKEX": ret = e.IO("api", "POST", "/api/v1/withdraw.do", "target=address&withdraw_amount=" + amount + "&symbol="+currency+"_usd&withdraw_address=" + address+"&chargefee="+fee+"&trade_pwd="+password); if (ret && ret.result) { withdraw_id = ret.withdraw_id; } break default: throw "不支持的操作"; } return {info: ret, withdraw_id: withdraw_id} } ```
