使用
隨機(jī)字符語(yǔ)法
支持大部分正則表達(dá)式的匹配語(yǔ)法
- \d 數(shù)字, 相當(dāng)于[0-9]
- \w 數(shù)字、字母加下劃線, 相當(dāng)于[0-9a-zA-Z_]
- \s 空白字符, 只包含空格和制表符
- . 除\n和\r以外的任意字符, 生成隨機(jī)字符時(shí)只在ascii碼0~255之間生成
- [a-zA-Z甲乙] 區(qū)間, 不支持^語(yǔ)法
- 以及其他字符
重復(fù)打印語(yǔ)法
與正則表達(dá)式的重復(fù)匹配語(yǔ)法相同
- ? 隨機(jī)生成0個(gè)或1個(gè)字符
- * 隨機(jī)生成0個(gè)以上字符, 默認(rèn)最多16個(gè)
- + 隨機(jī)生成1個(gè)以上字符, 默認(rèn)最多16個(gè)
- {n} 生成n個(gè)字符
- {n,} 隨機(jī)生成n~個(gè)字符, 默認(rèn)最多max(16,n)個(gè)
- {n,m} 隨機(jī)生成n~m個(gè)字符
其他語(yǔ)法
- | 或語(yǔ)法, 例如aaa|bbb|ccc隨機(jī)生成aaa或bbb或ccc, 概率相等
- () 支持括號(hào)
