24小时Unix时间戳的正则表达式



我想为一个 24 小时的 unix 时间戳创建一个正则表达式,从01/01/2015 00:00:00 **(1420066800)** to 01/01/2015 23:59:59 **(1420153199)**开始,这是 unix 时间戳格式中 86399 秒的差异。

我正在使用range_regexpython lib,但它对于如此大的范围来说是错误的。range_to_pattern方法(range_to_pattern(1420066800, 1420153199)(将产生正则表达式:1420[0-1][5-6][3-6][1-8]\d{2}这对于创建正则表达式的静态边界来说很好,但是当涉及到以下值时:1420159111因为左起的 7 位数字 (9( 不在第三个范围组 ([3-6]( 中。

有人可以提供更好的 python3 库或有关如何创建一天 86400 秒正则表达式的解决方法吗?

根据我上面的评论,您使用了该库中的错误函数。

您应该使用以下方法:

range_to_regex(1420066800, 1420153199)

这将返回正确的正则表达式:

142006680d|14200668[1-9]d|14200669d{2}|142006[7-9]d{3}|14200[7-9]d{4}|14201[0-4]d{4}|142015[0-2]d{3}|1420153[0-1]d{2}
