need

Requires a regular expression, used in nginx.
If $uri does not end with / and does not end with .xml, .html, or .htm, it will be permanent to $uri/.

location @rewrite {
    rewrite [^\/]$ $uri/ permanent;
    rewrite . /index.php?s=$uri&$args last;
}

try

My own writing method, but failed:

rewrite ([\/]|.xml|.html?)$ $uri/ permanent;

Question

1）如何才可以实现不以.xml .html /结尾的才重写的正则。
2）如何才可以在正则表达式[]中排除完整的一段单词？

Replenish

I used this sentence, and it seems that no problem has been found for the time being.

rewrite [^\/|\.xml|\.html?]$ $uri/ permanent;

Question, isn’t a-zA-Z0-9 in the square brackets []? Can you also write a complete matching string?
