java - 正则表达式求助，python的findall

问题描述

问 题

content = '[1502165009733][DEBUG][TID:140600116508416][asr_request_agent.cpp:219][ASRRequest::generate_asr_request] params json string: {"pam":"IDPAAS","idx":"2","pdt":"4006","glb":"e3dece1a-057f-4abe-94bc-46ebde36f844","enc":"utf-8","rtn":"json","ptc":"101","app":"com.baidu.aip.huatuo","fun":"262400"}'
# re.search()
print re.findall(reg, content)

正则是： ^\[(\d+)]|glb\":\"(.*)\",\"enc|\[(\d+)]|idx\":\"(.*)",\"pdt

可是为什么匹配的结果是
[('1502165009733', '', '', ''), ('', '', '', '2'), ('', 'e3dece1a-057f-4abe-94bc-46ebde36f844', '', '')]

数字里面有三个元素，而每个里面又有三个，但是想要的结果是
['1502165009733', 'e3dece1a-057f-4abe-94bc-46ebde36f844', '2']
想问一下是正则错误了还是确实这样？

解决方案

import re

reg = '\[(\d+)\][\s\S]*?"idx":"(\d+)"[\s\S]*?"glb":"(.*?)"'
content = '[1502165009733][DEBUG][TID:140600116508416][asr_request_agent.cpp:219][ASRRequest::generate_asr_request] params json string: {"pam":"IDPAAS","idx":"2","pdt":"4006","glb":"e3dece1a-057f-4abe-94bc-46ebde36f844","enc":"utf-8","rtn":"json","ptc":"101","app":"com.baidu.aip.huatuo","fun":"262400"}'
g = re.search(reg, content)
a, b, c = g.groups()

print a, b, c
