Python 在coinbase api上请求传输/发送时出错

我试图将coinbase api从一个加密帐户转移到另一个加密帐户，但似乎无法实现。当我尝试传输2次时，错误出现在代码底部。第一次，它返回的是“{}”，第二次返回的是回溯错误

这是我的密码：

import hmac, hashlib, time, requests, os
from requests.auth import AuthBase
from coinbase.wallet.client import Client

API_KEY = os.environ.get('API_KEY')
API_SECRET = os.environ.get('API_SECRET')
xrp_acct_id = os.environ.get('XRP_ID')
usdc_acct_id = os.environ.get('USDC_ID')
xrp_destination_tag = os.environ.get('xrp_destination_tag')
xtz_acct_id = os.environ.get('XTZ_ID')
user_id = os.environ.get('Coinbase_User_Id')


# Create custom authentication for Coinbase API
class CoinbaseWalletAuth(AuthBase):
    def __init__(self, api_key, secret_key):
        self.api_key = api_key
        self.secret_key = secret_key

    def __call__(self, request):
        timestamp = str(int(time.time()))
        message = timestamp + request.method + request.path_url + (request.body or b'').decode()
        signature = hmac.new(bytes(self.secret_key, 'utf-8'), message.encode('utf-8'), hashlib.sha256).hexdigest()

        request.headers.update({
            'CB-ACCESS-SIGN': signature,
            'CB-ACCESS-TIMESTAMP': timestamp,
            'CB-ACCESS-KEY': self.api_key,
            'CB-VERSION': '2020-01-18'
        })
        return request


api_url = 'https://api.coinbase.com/v2/'
auth = CoinbaseWalletAuth(API_KEY, API_SECRET)
client = Client(API_KEY, API_SECRET)

# Get current user:
#       r_user = requests.get(api_url + 'user', auth=auth)
#       print(r_user.json())

# Get transactions:
# xrp_txs = client.get_transactions(xrp_acct_id)

# Get accounts:
r = requests.get(api_url + 'accounts', auth=auth)

# Get price (XRP-USD):
price = client.get_spot_price(currency_pair='XRP-USD')

# To parse the JSON
accounts_json = r.json()
#
# # Variable to figure out wallet balances
XRP_balance = 0.0

# Dictionary used to store balances and wallet name's
accounts = {}

# Loop to get balances
for i in range(0, len(accounts_json["data"])):
    wallet = accounts_json["data"][i]["name"]
    amount = accounts_json["data"][i]["balance"]["amount"]

    # Switch statement to figure out which index which wallet is
    if wallet == "XRP Wallet":
        XRP_balance = float(amount) * float(price["amount"])
        accounts["XRP_USD"] = XRP_balance
    elif wallet == "USDC Wallet":
        USDC_amount = amount
        accounts["USDC"] = USDC_amount
    else:
        print()

print(accounts)

我检查了我的tezos账户，当然因为回复是201，所以它确实发送给了自己。我最近发现，当您没有指定目的地标记时，它不会这样做，但仍然存在BUG

如果你想将密码从一种货币转换成另一种货币，你不必使用转账。从webapp查看您需要调用的端点Coinbase API：

必须知道您想要出售的加密软件的基本id和想要购买的加密软件的基本id。您可以通过调用

GET”来了解它https://api.coinbase.com/v2/ /资产/价格？基础=美元&过滤器=可持有&分辨率=最新”，并从您的货币的“基础id”响应中获取

通过调用

POST”下订单https://api.coinbase.com/v2/trade“

请求主体为json，如下所示：

{'amount'：[您要转换的金额]，'amount\u asset'：[您要转换的金额的货币]，'amount\u from'：'input'，'source\u asset'：[您要出售的加密的“base\u id]，'target\u asset'：[您要购买的加密软件的“基本id”}

如果先前的POST“/trade”响应代码为201，则必须获取 响应的json的“id”值，并通过 调用

POST”https://api.coinbase.com/v2/trades/[上一次json响应的id]https://api.coinbase.com/v2/trade 发布“]/commit

。如果 此POST commit的响应代码为201，您的exchange为 已启动，如果coinbase中没有错误，则转换为 完成了
