nginx - Nginx替换字符重写？

Question

假设您有一个 URL www.answers.mydomain.com/category/hello_world-123.html 但您想将路径部分重写为 /category/hello-world

你将如何通过 nginx 重写来解决这个问题？基本上如何格式化 $1 变量？

 

     server{
       listen 80;
       server_name  ~^(?<subdomain>.+)\.bg\.com$
       root /home/dan/Projects/rewrite-example;


       set $PREFERRED_DOMAIN $scheme://www.bg.com;

       if ($subdomain ~* answers) {
         rewrite ^(.*)$ $PREFERRED_DOMAIN/questions$1 permanent;
       }
     } 

 

Answer 1

 server{
     listen 80;
     server_name  answers.bg.com;

     rewrite ^(.+/[a-z]+)-\d+\.html$ http://www.bg.com$1 permanent;
     rewrite ^(.+/[a-z]+)_([a-z]+)-\d+\.html$ http://www.bg.com$1-$2 permanent;
     rewrite ^(.+/[a-z]+)_([a-z]+)_([a-z]+)-\d+\.html$
             http://www.bg.com$1-$2-$3 permanent;
     rewrite ^(.+/[a-z]+)_([a-z]+)_([a-z]+)_([a-z]+)-\d+\.html$
             http://www.bg.com$1-$2-$3-$4 permanent;
     rewrite ^(.+/[a-z]+)_([a-z]+)_([a-z]+)_([a-z]+)_([a-z]+)-\d+\.html$
             http://www.bg.com$1-$2-$3-$4-$5 permanent;
 }
