问题是，当我有这样的行时，[NVS:FAXG3.1.0/+44614215421]它返回无，有没有办法让第二个停止，NVS:这样它就会停止，就像我们有这样的行data2

data = "13:16:16.146 mta         Messages       I CC Doc O:NVS:SMTP/me@test.no R:NVS:SMTP.0/server@test.de [NVS:FAXG3.1.0/+44614215421] mid:41414"
print extract(data)

它返回

>>>None

data2 = "13:16:16.146 mta         Messages       I CC Doc O:NVS:SMTP/me@test.no R:NVS:SMTP.0/server@test.de  mid:41414"
print extract(data2)

它返回

>>> {'Destination': 'server@test.de', 'mid': '41414', 'Type S': 'SMTP', 'Origine': 'me@test.no', 'Type D': 'SMTP.0', 'Heure': '13:16:16.146'}

肮脏的黑客

只需更换

if len(k)==2:

至

if len(k)>1:

因为它在第二个字符串中找到了超过 2 个匹配项
