在我的大多数 nginx 配置文件中，我有以下几行：

    location /resources {
        autoindex off;
        if ($request_filename ~* ^.+.tpl$) {
            rewrite ^ /404.html;
        }
        try_files $uri /resources/index.php?$args;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2)$ {
        expires 365d;
        # add_header Cache-Control "public, no-transform";
        add_header Cache-Control "no-cache, public, must-revalidate, proxy-revalidate";
    }

    location / {

        # Redirect /foobar/ and /foobar/index.html to /foobar
        rewrite ^(.+)/+$ $1 permanent;
        rewrite ^(.+)/index.html$ $1 permanent;

        if ($request_uri ~ ^/(.*)\.html$) {
            return 302 /$1;
        }

        try_files $uri $uri.html $uri/index.html =404;
        # try_files $uri $uri/ /index.php$is_args$args;
    }

如果存在，我想删除以下块：

    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2)$ {
        expires 365d;
        # add_header Cache-Control "public, no-transform";
        add_header Cache-Control "no-cache, public, must-revalidate, proxy-revalidate";
    }

使用 regex101.com 我想出了以下正则表达式来“匹配”该块：

/((location ~\* \\\.\(js\|css\|png\|jpg\|jpeg\|gif\|ico\|svg\|woff\|woff2\)\$ \{)([^}]*)(\}))/mg

regex101 代码生成器生成以下代码：

sed -E 's/((location ~\* \\\.\(js\|css\|png\|jpg\|jpeg\|gif\|ico\|svg\|woff\|woff2\)\$ \{)([^}]*)(\}))//mg;t;d' <<< "    location /resources {
        autoindex off;
        if ($request_filename ~* ^.+.tpl$) {
            rewrite ^ /404.html;
        }
        try_files $uri /resources/index.php?$args;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2)$ {
        expires 365d;
        # add_header Cache-Control \"public, no-transform\";
        add_header Cache-Control \"no-cache, public, must-revalidate, proxy-revalidate\";
    }

    location / {

        # Redirect /foobar/ and /foobar/index.html to /foobar
        rewrite ^(.+)/+$ $1 permanent;
        rewrite ^(.+)/index.html$ $1 permanent;

        if ($request_uri ~ ^/(.*)\.html$) {
            return 302 /$1;
        }

        try_files $uri $uri.html $uri/index.html =404;
        # try_files $uri $uri/ /index.php$is_args$args;
    }"

但它不会产生任何输出。

如果我想在给定的配置文件中删除该配置部分，我该如何实现这一点，比如说 name myhost.localhost.conf？
