NovaExchange API：将Python代码转换为NodeJS

我正在为NODEJS编写一个API，但novaexchange站点上提供的示例是用Python编写的，因此我很难在NodeJS中编写相应的代码。 帮助将不胜感激。 代码写在Python中https://www.novaexchange.com/remote/faq/

#!/usr/bin/python import time import hmac import hashlib import base64 import requests # https://novaexchange.com/remote/faq/ API_KEY = "YOUR_API_KEY" API_SECRET = "YOUR_API_SECRET" public_set = set([ "markets", "market/info", "market/orderhistory", "market/openorders" ]) # optional private_set = set([ "getbalances", "getbalance", "getdeposits", "getwithdrawals", "getnewdepositaddress", "getdepositaddress", "myopenorders", "myopenorders_market", "cancelorder", "withdraw", "trade", "tradehistory", "getdeposithistory", "getwithdrawalhistory", "walletstatus" ]) url = "https://novaexchange.com/remote/v2/" def api_query( method, req = None ): url = "https://novaexchange.com/remote/v2/" if not req: req = {} if method.split('/')[0][0:6] == 'market': r = requests.get( url + method + '/', timeout = 60 ) elif method.split('/')[0] in private_set: url += 'private/' + method + '/' + '?nonce=' + str( int( time.time() ) ) req["apikey"] = API_KEY req["signature"] = base64.b64encode( hmac.new( API_SECRET, msg = url, digestmod = hashlib.sha512 ).digest() ) headers = {'content-type': 'application/x-www-form-urlencoded'} r = requests.post( url, data = req, headers = headers, timeout = 60 ) return r.text # Eample usage: # Public: # print api_query( "markets" ) print api_query( "market/orderhistory/" + "LTC_DOGE" ) # etc... # Private: print api_query("getbalances") # print api_query( "trade/" + "LTC_DOGE", { 'tradebase': 0, 'tradetype': "BUY", 'tradeprice': 0.000001, 'tradeamount': 1000 } ) # print api_query( 'cancelorder/' + str( 1426936 ) ) # print api_query( 'tradehistory' ) # etc...
