Bittrex v3 API-无效签名响应

Question

我正在尝试使用Bittrex v3 beta API，但我不断得到：

{'code': 'INVALID_SIGNATURE'}

作为回应。

我已经使用Javascript和Python进行过尝试，所以我同时包含了这两个脚本-如果您发现任何错误，请告诉我。

Python（首次尝试）：

#!/Users/eamonwhite/.pyenv/versions/3.6.3/bin/python3.6
import requests
import time
import hashlib
from pprint import pprint
import json
import hmac
import base64
import codecs

# api-endpoint 
url = "https://api.bittrex.com/v3/orders/closed"

api_key = b'yyyyyyyyy'
secret = b'xxxxxxxxx'

api_timestamp = str(int(time.time() * 1000))
print(api_timestamp)

params = {'marketSymbol':'BTC-LOOM','pageSize': 200,'startDate': '2019-09-25T01:10:27.000','endDate': '2019-09-25T01:29:27.000'}

signature = hashlib.sha512(b'').hexdigest()

pre_sign = api_timestamp+url+'GET'+signature
print(pre_sign)

pre_sign_var = pre_sign.encode()
sig = hmac.new(secret, pre_sign_var, hashlib.sha512).hexdigest()
headers = {'Api-Key': api_key, 'Api-Timestamp': api_timestamp, 'Api-Content-Hash': signature, 'Api-Signature': sig}
# sending get request and saving the response as response object 
r = requests.get(url = url, params = params, headers = headers) 

# extracting data in json format 
data = r.json() 

pprint(data)

Javascript（第二次尝试-直接从API文档中提取）：

var CryptoJS = require("crypto-js");
const fetch = require('node-fetch');

const url = 'https://api.bittrex.com/v3/orders/closed';
const data = {'marketSymbol':'BTC-LOOM','pageSize': 200,'startDate': '2019-09-25T01:10:27.000','endDate': '2019-09-25T01:29:27.000'};

var content_hash = CryptoJS.SHA512('').toString(CryptoJS.enc.Hex);

var api_timestamp = new Date().getTime();

var pre_sign_string = api_timestamp+url+'GET'+content_hash;
var signature = CryptoJS.HmacSHA512(pre_sign_string, 'xxxxxxsecretxxxxx').toString(CryptoJS.enc.Hex);

const headers = {'Api-Key': 'zzzzz', 'Api-Timestamp': api_timestamp, 'Api-Content-Hash': content_hash, 'Api-Signature': signature, 'Content-Type': 'application/json'};

function obj_to_query(obj, base_url) {
    var parts = [];
    for (var key in obj) {
        if (obj.hasOwnProperty(key)) {
            parts.push(encodeURIComponent(key) + '=' + encodeURIComponent(obj[key]));
        }
    }
    return base_url+"?" + parts.join('&');
}

async function getOrders(url = '', data = {}, headers = {}) {

  return fetch(url, {
          method: 'get',
          headers: headers,
      })
      .then(res => res.json())
      .then(json => {
        console.log(json)
        return json
      });
}

var query_string = obj_to_query(data, url)

var r = getOrders(query_string, data, headers);

console.log(r);

我返回的错误与Api-Signature标头有关，所有其他标头都是正确的，否则它们将引发错误-我已经在签名之前输出了我拥有的字符串，它看起来与在文档中，所以我觉得API肯定有问题，因为它仍处于测试阶段。

请让我知道是否是这种情况，所以我不再尝试:)谢谢

最终使它工作起来并不确定为什么，但是我所做的一件事是将我的url移出该变量，并将其包含在创建已编码URI字符串的函数的return语句中。但是，它总是返回相同的数据不管我使用什么marketSymbol，只有几笔交易回来...这是我每次/ orders / closed都会得到的输出，而不管marketSymbol：
