enable性能优化缓存机制与批量处理对于需要频繁生成密钥的场景可以实现密钥缓存机制import hashlib import json from functools import lru_cache lru_cache(maxsize100) def generate_cached_key(username, company, serial, user_num): key_hash hashlib.md5( f{username}{company}{serial}{user_num}.encode() ).hexdigest() cache_file fcache/{key_hash}.key if os.path.exists(cache_file): with open(cache_file, r) as f: return f.read() key LicenseEncoder( usernameusername, atsitecompany, user_numuser_num, serial_numserial ).encode() os.makedirs(cache, exist_okTrue) with open(cache_file, w) as f: f.write(key) return
