本文使用 requests 库来调用 Binance REST API。如果你更喜欢 API 库，你可以尝试 python-binance。 Binance REST API 有 3 种类型的安全接口：NONE：可以自由访问USER_STREAM 和 MARKET_DATA：需要 APIKeyTRADE 和 USER_DATA：需要 APIKey 和签名获取币安 APIKey 和 SecretKey BinanceDashboard -> Settings -> APIManagementhttps://www.binance.com/en/usercenter/settings/api-management 创建带有标签的 APIKey（用于标识密钥用途和用途的名称）：生成 APIKey 和 SecretKey。 注意：请立即复制密钥，因为您无法在稍后阶段再次检索密钥，除非您创建另一个新密钥。 您可以设置 API 限制：只读、启用交易、启用提款。 您可以限制某些特定 IP 访问 API。import time import json import hmac import hashlib import requests from urllib.parse import urljoin, urlencode API_KEY = 'UIGu...'
