NGINX-正则表达式-在整个位置搜索非字母数字

我的vhost conf中有以下正则表达式：

location ~* ^/!/[^a-zA-Z0-9] {
    return 301 $scheme://$http_host;
}

但它似乎只与第一个字符匹配：

# Redirects to https://shouttag.com correctly
https://shouttag.com/!/!pink

# Does not redirect as expected
https://shouttag.com/!/p!nk

我尝试过的变化：

# Assume that $is unnecessary b/c I don't know what the end of the url may be
location ~* ^/!/[^a-zA-Z0-9]${

# Only seems to work when capturing data via group syntax ()
location ~* ^/!/[^a-zA-Z0-9]+ {

谢谢.
最佳答案
您可以尝试以下规则：

location ~ ^/!/[a-zA-Z0-9]*[^a-zA-Z0-9].*${
    return 301 $scheme://$http_host;
}
