我想设置一个正则expression式的path/s/<4-6 character string here>我/s/<4-6 character string here>哪里捕获4-6字符的string为$ 1。
我尝试使用以下两个条目，但都失败
location ~ ^/s/([0-9a-zA-Z]){4,6}+$ { ... location ~ ^/s/([0-9a-zA-Z]{4,6})+$ { ...
第一个出现“未知指令”，第二个出现“pcre_compile（）失败：缺less）'

以下路线将由这个位置服务：
/s/1234 (and I would capture '1234' in $1) /s/12345 (and I would capture '12345' in $1) /s/123456 (and I would capture '123456' in $1) /s/abcd (and I would capture 'abcd' in $1) /s/abcde (and I would capture 'abcde' in $1) /s/abcdef (and I would capture 'abcdef' in $1) /s/a1b2c (and I would capture 'a1b2c' in $1)
以下路线将不会由这个位置提供：
/s/1 /s/12 /s/123 /s/a /s/ab /s/abc /s/abc1234 /s/12345678
等等…
如果你想捕捉4到6个字符，为什么你没有把量词放在捕捉括号内？
也许这样的东西：
location ~ "^/s/([0-9a-zA-Z]{4,6})$" {...
大括号用于正则表达式和块控制，你必须用引号括起（单个或双）（< – wiki nginx）
