从任何包中提取和匹配协议and消息typename的首选方法

^(\w+)\.(\w+)$

import re

def extract_protocol_and_message_typename(string):
    pattern = r'^(\w+)\.(\w+)$'
    match = re.match(pattern, string)
    if match:
        protocol = match.group(1)
        message_typename = match.group(2)
        return protocol, message_typename
    else:
        return None

# 示例用法
string = "protocol.message"
result = extract_protocol_and_message_typename(string)
if result:
    protocol, message_typename = result
    print("Protocol:", protocol)
    print("Message Typename:", message_typename)
else:
    print("Invalid string")

Protocol: protocol
Message Typename: message
