Nginx 如何使用正则表达式掩码删除 URL 的一部分来进行重定向？

我需要从 URL 重定向到 example.com/some-urltext-nav.html（仅删除“-nav”）。我在块example.com/some-urltext.html中尝试了一些正则表达式，但什么也没发生……serverrewrite ^.*?-nav\.html$/

server {
    server_name example.com cdn.example.com www.example.com;
    charset off;
    index index.php index.html;
    disable_symlinks if_not_owner from=$root_path;
    include /etc/nginx/vhosts-includes/*.conf;
    include /etc/nginx/vhosts-resources/example.com/*.conf;
    access_log /var/www/httpd-logs/example.com.access.log;
    error_log /var/www/httpd-logs/example.com.error.log notice;
    ssi on;
    set $root_path /var/www/main/data/www/example.com;
    

    
    
    location / {
    
        location ~ [^/]\.ph(p\d*|tml)$ {
            try_files /does_not_exists @php;
        }
        location ~ ^/(?<capture>.+)-nav\.html$ {
        return 302 /$capture.html;
        }

        location ~* ^.+\.(jpg|jpeg|gif|png|svg|js|css|mp3|ogg|mpe?g|avi|zip|gz|bz2?|rar|swf)$ {

以下代码片段应该符合您的期望：

location ~ ^(?<prefix>/.+?)-nav(?<suffix>\.html)$ {
    return 301 https://$host$prefix$suffix;
}

正则表达式将关键字前后的部分捕获到变量中，然后用于形成return语句URL。

更新：

您的配置有

location ~ [^/]\.ph(p\d*|tml)$ {

在上述规则之前。此规则匹配以 结尾的任何路径ml。因此，nginx 会将其用于location以 结尾的任何请求html。

您需要交换两个location块的位置以确保 nginx 评估第一个块。

此外，这个正则表达式看起来相当“漏洞百出”。您可能需要重新考虑一下您到底想让正则表达式匹配什么，并确保它只匹配那些项目。
