使用 python3 的 Coinbase 高级交易 API 连接不起作用

Question

我根据 coinbase 文档 coinbase doc 尝试了以下代码 该文档是为 Python2 提供的，但我已经修改并将其用于 Python3，因为我正在尝试连接到 Coinbase 中的高级交易 API Coinbase Advanced trade doc

import datetime
import time
import hmac
import hashlib
import http.client


secret_key='***'    #hidden
api_key='***'       #hidden

date_time = datetime.datetime.utcnow()
timestamp=int(time.mktime(date_time.timetuple())) # timestamp should be from UTC time and no decimal allowed

method = "GET" # method can be GET or POST. Only capital is allowed
request_path = 'api/v3/brokerage/accounts'
body=''
message= str(timestamp) + method + request_path + body
signature = hmac.new(secret_key.encode('utf-8'), message.encode('utf-8'), hashlib.sha256).hexdigest()


headers={
'accept':'application/json',
'CB-ACCESS-KEY': api_key,
'CB-ACCESS-TIMESTAMP': timestamp,
'CB-ACCESS-SIGN': signature
}


conn = http.client.HTTPSConnection("api.coinbase.com")
payload = ''

conn.request("GET", "/api/v3/brokerage/accounts", payload, headers)
res = conn.getresponse()
data = res.read()
print(data.decode("utf-8"))

执行此代码时，我期待帐户详细信息。但我越来越未经授权的错误API 返回错误代码 401。

我之前能够连接到 Coinbase Pro API，一切都很好，直到 coinbase 和 Coinbase Pro 合并。现在无法弄清楚如何连接到 coinbase 中的高级交易功能。

好的，所以我进行了两次更新以使其运行。

1. 在 request_path = '/api/v3/brokerage/accounts' 中的 api 之前插入一个 / :)

2. 将生成 timestamp 的方式更改为 timestamp = str(int(time.time()))。

   我认为将您的 timestamp 更新为一个字符串可以修复它，但它没有，所以我恢复了生成它的方式。也许有人可以告诉我们为什么一个有效而另一个无效。如果我弄明白了，我一定会更新这篇文章。

   这是完整的工作代码。我保持其他一切不变，但用我的替换了你的 cmets。

   import datetime
   import time
   import hmac
   import hashlib
   import http.client
   
   secret_key = '***'  
   api_key = '***'  
   
   # This is the first part where you were getting time
   #date_time = datetime.datetime.utcnow() 
   
   # And this is the second part where you format it as an integer
   #timestamp=int(time.mktime(date_time.timetuple())) 
   
   # I cast your timestamp as a string, but it still doesn't work, and I'm having a hard time figuring out why.
   #timestamp=str(int(time.mktime(date_time.timetuple()))) 
   
   # So I reverted to the way that I'm getting the timestamp, and it works
   timestamp = str(int(time.time()))
   
   method = "GET"
   request_path = '/api/v3/brokerage/accounts' # Added a forward slash before 'api'
   body=''
   message= str(timestamp) + method + request_path + body
   signature = hmac.new(secret_key.encode('utf-8'), message.encode('utf-8'), hashlib.sha256).hexdigest()
   
   
   headers={
   'accept':'application/json',
   'CB-ACCESS-KEY': api_key,
   'CB-ACCESS-TIMESTAMP': timestamp,
   'CB-ACCESS-SIGN': signature
   }
   
   
   conn = http.client.HTTPSConnection("api.coinbase.com")
   payload = ''
   
   conn.request("GET", "/api/v3/brokerage/accounts", payload, headers)
   # You were probably troubleshooting, but the above line is redundant and can be simplified to:
   # conn.request("GET", request_path, body, headers) 
   
   res = conn.getresponse()
   data = res.read()
   print(data.decode("utf-8"))

我看到有人为 Advanced Trade 端点开源了一个 python 库：https://github.com/KmiQ/coinbase-advanced-python
