Nginx：将/sitemap.xml重写为/ sitemap

Question

我有一个Codeigniter PHP应用程序，我已经配置了我的nginx conf以获得一些URL。例如，/ index.php / home将重写为/ home。现在我正在尝试配置nginx以将http://mysite.com/sitemap.xml重写为/ sitemap（构造xml文件）。这是我在我的nginx conf中使用的：

            if ($request_uri ~* ^/sitemap.xml)
        {
            rewrite ^/(.*)$ /index.php/sitemap last;
        }

出于某种原因，上述方法不起作用，我认为另一条规则可能存在冲突，但我无法找到解决方法。有人可以帮忙吗？ （完整配置文件如下）

       server {
            listen   80;

            root   /www/myapp;
            index index.php index.html index.htm;

            access_log  /var/log/nginx/access.log;

            if (-f /www/myapp/application/errors/error_503.html)
            {
                return 503;
            }

            # canonicalize codeigniter url end points
            #/home will redirect to /
            if ($request_uri ~* ^(/home(/index)?|/index(.php)?)/?$)
            {
                rewrite ^(.*)$ / permanent;
            }

            # removes trailing "index" from all controllers
            if ($request_uri ~* index/?$)
            {
                rewrite ^/(.*)/index/?$ /$1 permanent;
            }

            # removes trailing slashes (prevents SEO duplicate content issues)
            if (!-d $request_filename)
            {
                rewrite ^/(.+)/$ /$1 permanent;
            }

            # removes access to "system" folder, also allows a "System.php" controller
            if ($request_uri ~* ^/system)
            {
                rewrite ^/(.*)$ /index.php?/$1 last;
                break;
            }

            {

Answer 1

上面的问题是REQUEST_URI仍然是/sitemap.xml而不是/ sitemap，因此CI无法正确路由它。尝试将“last”更改为“redirect”：

        if ($request_uri ~* ^/sitemap.xml)
        {
            rewrite ^/(.*)$ /sitemap redirect;
        }

还可以考虑使用LOCATION而不是IF（一般避免使用IF）：

        location = /sitemap.xml
        {
            rewrite .* /sitemap redirect;
        }

希望有所帮助

我在我的网站上使用它：

# Sitemap.xml
location /sitemap.xml {
    alias /venvs/mobilepro/src/mobilepro/static/maps/map.xml;
}
