• https://zerosteiner.github.io/rule-engine/ 下次一定要尝试一次 比如我们此次的急诊分诊功能，完全适配这种场景 再比如我们的日期归一也建议采纳这种方案

使用示例1:

# first define the rule to use for matching / filtering
rule = rule_engine.Rule('date == $today and "Alice" in donors')
# next define the event object with it's attributes which will be symbols
event = {
    'date': datetime.date.today(),
    'donors': ['Alice', 'Bob'],  # new ARRAY type
    'title': 'Annual Fundraiser'
}
# apply the rule on the event object
rule.matches(event) # => True

使用示例2:

# check for 3 or more events of tcp traffic going to port 4444
rule = rule_engine.Rule(
    'protocol == "tcp" and dst.port == 4444 and seen.length >= 3'
)
# evaluate the
rule.matches({
    'dst': {'addr': '172.16.50.81', 'port': 4444},
    'src': {'addr': '192.168.1.20', 'port': 53718},
    'protocol': 'tcp',
    'seen': [
        datetime.date(2019, 7, 6),
        datetime.date(2019, 8, 17),
        datetime.date(2019, 9, 29)
    ]
}) # => True
