代码如下，正则如果只匹配user_id":(.*?),"fullname":"(.*?)"是可以匹配出所有，但是再往后加上start_time": (.*?)，匹配就为空
问题：是不是因为中间隔着“计算机课”这几个汉字，所以才不能匹配出start_time的吗？

import re

response = '{"teacher_id":5114,"attendance_id":7727052,"user_id":16786743,"fullname":"张三","lesson_name":"计算机课","lesson_start_time":1633860985,"lesson_end_time":1633862410,"conversion_status":1},{"teacher_id":5114,"attendance_id":8062199,"user_id":12956827,"fullname":"李四","lesson_name":"计算机课","lesson_start_time":1638620201,"lesson_end_time":1638622728,"conversion_status":1},{"teacher_id":5114,"attendance_id":7961271,"user_id":12769816,"fullname":"王五","lesson_name":"计算机课","lesson_start_time":1637061349,"lesson_end_time":1637064881,"conversion_status":1}'
student = re.findall(
    'user_id":(.*?),"fullname":"(.*?)".*start_time": (.*?),"lesson_end_time', response)
print(student)

start_time" : 和 (.*?) 之间有一个空格

*start_time"，写错了吧

多打了空格

中文编码范围，中文汉字的正则也许用的着。
双字节字符编码范围：
1. GBK (GB2312/GB18030)
\x00-\xff GBK双字节编码范围
\x20-\x7f ASCII
\xa1-\xff 中文gb2312
\x80-\xff 中文 gbk

2. UTF-8 (Unicode)
\u4e00-\u9fa5 (中文)
\x3130-\x318F (韩文)
\xAC00-\xD7A3 (韩文)
\u0800-\u4e00 (日文)
如果想在Android Studio 中查找汉字
可以使用正则搜索
[\u4e00-\u9fa5]

请完整分析cszcszv16的代码，，人家的没问题

cszcszv163 · 发表于 2021-12-5 16:35
