火币工作python 3.6示例创建url包括签名

问题描述

为火币 API 生成有效 url（包括签名）的工作示例。

在火币api文档中没有明确的例子可以让你一步一步验证你的签名创建方法。

我的意图是在这里创建它，但我需要帮助，因为我还没有做到。

以下应该是食谱。

请注意，一旦您完成此操作，请用有效值替换您的 API 密钥 + 密钥和时间戳：

import hmac
import hashlib
import base64

from urllib.parse import urlencode

API_KEY = 'dummy-key'
API_SECRET = 'dummy-secret'
timestamp = '2021-03-04T11:36:39'

params_dict = {
    'AccessKeyId': API_KEY,'SignatureMethod': 'HmacSHA256','Signatureversion': '2','Timestamp': timestamp
}
params_url_enc = urlencode(sorted(params_dict.items()))

pre_signed = 'GET\n'
pre_signed += 'api.huobi.pro\n'
pre_signed += '/v1/account/accounts\n'
pre_signed += params_url_enc

sig_bytes = hmac.new(
    API_SECRET.encode(),pre_signed.encode(),hashlib.sha256).hexdigest().encode()
sig_b64_bytes = base64.b64encode(sig_bytes)
sig_b64_str = sig_b64_bytes.decode()
sig_url = urlencode({'Signature': sig_b64_str})

url = 'https://api.huobi.pro/v1/account/accounts?'
url += params_url_enc + '&'
url += sig_url

print('API_KEY={}'.format(API_KEY))
print('API_SECRET={}'.format(API_SECRET))
print('timestamp={}'.format(timestamp))
print('params_dict={}'.format(params_dict))
print('params_url_enc={}'.format(params_url_enc))
print('pre_signed:\n{}'.format(pre_signed))
print('sig_bytes={}'.format(sig_bytes))
print('sig_b64_bytes={}'.format(sig_b64_bytes))
print('sig_b64_str={}'.format(sig_b64_str))
print('sig_url={}'.format(sig_url))
print('url={}'.format(url))

给出：

API_KEY=dummy-key
API_SECRET=dummy-secret
timestamp=2021-03-04T11:36:39
params_dict={'AccessKeyId': 'dummy-key','Timestamp': '2021-03-04T11:36:39'}
params_url_enc=AccessKeyId=dummy-key&SignatureMethod=HmacSHA256&Signatureversion=2&Timestamp=2021-03-04T11%3A36%3A39
pre_signed:
GET
api.huobi.pro
/v1/account/accounts
AccessKeyId=dummy-key&SignatureMethod=HmacSHA256&Signatureversion=2&Timestamp=2021-03-04T11%3A36%3A39
sig_bytes=b'1921de9f42284bc0449c5580f52a9f7e7e3a54a6e8befc0d320992e757517a6b'
sig_b64_bytes=b'MTkyMWRlOWY0MjI4NGJjMDQ0OWM1NTgwZjUyYTlmN2U3ZTNhNTRhNmU4YmVmYzBkMzIwOTkyZTc1NzUxN2E2Yg=='
sig_b64_str=MTkyMWRlOWY0MjI4NGJjMDQ0OWM1NTgwZjUyYTlmN2U3ZTNhNTRhNmU4YmVmYzBkMzIwOTkyZTc1NzUxN2E2Yg==
sig_url=Signature=MTkyMWRlOWY0MjI4NGJjMDQ0OWM1NTgwZjUyYTlmN2U3ZTNhNTRhNmU4YmVmYzBkMzIwOTkyZTc1NzUxN2E2Yg%3D%3D
url=https://api.huobi.pro/v1/account/accounts?AccessKeyId=dummy-key&SignatureMethod=HmacSHA256&Signatureversion=2&Timestamp=2021-03-04T11%3A36%3A39&Signature=MTkyMWRlOWY0MjI4NGJjMDQ0OWM1NTgwZjUyYTlmN2U3ZTNhNTRhNmU4YmVmYzBkMzIwOTkyZTc1NzUxN2E2Yg%3D%3D

也在发送时添加标题：

{"Content-Type": "application/x-www-form-urlencoded"}

不幸的是，当我替换我自己的有效 API 密钥 + 密钥和正确的 UTC 时间戳时，我总是收到：

{"status":"error","err-code":"api-signature-not-valid","err-msg":"Signature not valid: Verification failure [校验失败]","data":null}

那么这里出了什么问题？

解决方法

火币API文档是 https://huobiapi.github.io/docs/spot/v1/en/#introduction

要获取所有帐户，请使用端点 GET /v1/account/accounts

from datetime import datetime
import requests
import json
import hmac
import hashlib
import base64
from urllib.parse import urlencode

#Get all Accounts of the Current User
AccessKeyId = 'xxxxx-xxxxx-xxxxx-xxxxx'
SecretKey = 'xxxxx-xxxxx-xxxxx-xxxxx'
timestamp = str(datetime.utcnow().isoformat())[0:19]
params = urlencode({'AccessKeyId': AccessKeyId,'SignatureMethod': 'HmacSHA256','SignatureVersion': '2','Timestamp': timestamp
                   })
method = 'GET'
endpoint = '/v1/account/accounts'
base_uri = 'api.huobi.pro'
pre_signed_text = method + '\n' + base_uri + '\n' + endpoint + '\n' + params
hash_code = hmac.new(SecretKey.encode(),pre_signed_text.encode(),hashlib.sha256).digest()
signature = urlencode({'Signature': base64.b64encode(hash_code).decode()})
url = 'https://' + base_uri + endpoint + '?' + params + '&' + signature
response = requests.request(method,url)
accts = json.loads(response.text)
print(accts)

随后，如果您需要运行另一个端点（注意时间戳允许为 ±5 分钟），

例如，要获取帐户余额，请使用 GET /v1/account/accounts/{account_id}/balance

#Get Account Balance of a Specific Account
account_id = accts['data'][0]['id']
method = 'GET'
endpoint = '/v1/account/accounts/{}/balance'.format(account_id)
pre_signed_text = method + '\n' + base_uri + '\n' + endpoint + '\n' + params
hash_code = hmac.new(SecretKey.encode(),url)
r = json.loads(response.text)
print(r)

错误是我取了哈希的十六进制，而需要摘要。

这里的工作配方：

import hmac
import hashlib
import base64

from urllib.parse import urlencode

API_KEY = 'dummy-key'
API_SECRET = 'dummy-secret'
timestamp = '2021-03-04T12:54:56'

params_dict = {
    'AccessKeyId': API_KEY,'Timestamp': timestamp
}
params_url_enc = urlencode(
    sorted(params_dict.items(),key=lambda tup: tup[0]))

pre_signed = 'GET\n'
pre_signed += 'api.huobi.pro\n'
pre_signed += '/v1/account/accounts\n'
pre_signed += params_url_enc

sig_bin = hmac.new(
    API_SECRET.encode(),pre_signed.encode(),hashlib.sha256).digest()
sig_b64_bytes = base64.b64encode(sig_bin)
sig_b64_str = sig_b64_bytes.decode()
sig_url = urlencode({'Signature': sig_b64_str})

url = 'https://api.huobi.pro/v1/account/accounts?'
url += params_url_enc + '&'
url += sig_url

print('API_KEY={}'.format(API_KEY))
print('API_SECRET={}'.format(API_SECRET))
print('timestamp={}'.format(timestamp))
print('params_dict={}'.format(params_dict))
print('params_url_enc={}'.format(params_url_enc))
print('pre_signed:\n{}'.format(pre_signed))
print('sig_bin={}'.format(sig_bin))
print('sig_b64_bytes={}'.format(sig_b64_bytes))
print('sig_b64_str={}'.format(sig_b64_str))
print('sig_url={}'.format(sig_url))
print('url={}'.format(url))

结果：

$ python test_huobi_so.py
API_KEY=dummy-key
API_SECRET=dummy-secret

params_dict={'AccessKeyId': 'dummy-key','Timestamp': '2021-03-04T12:54:56'}
