通过 url 参数根据区域设置在 nginx 上设置自定义 404 错误页面

Set custom 404 error page on nginx based on locale through url parameter

我是 运行 GNU/Linux OS 上 Nginx 的最新稳定版本,并且拥有以下虚拟主机,我正在尝试 setup custom localized 404 error pages avoiding if但我总是陷入重定向循环。

到目前为止,我只考虑以下区域设置 esenca,我将它们作为 URL 参数获取,始终在域旁边. expected URLs are 类似于:

http://www.example.com/ca
http://www.example.com/ca/home
http://www.example.com/en
http://www.example.com/en/contact

这是我的 nginx 服务器块:

server {
        listen          80;
        listen          [::]:80;
        server_name     example.com;
        root            /var/www/html/example_com;
        # By default, show Castilian index
        index           es/index.html;

        access_log      /var/log/nginx/example_com.access.log main;
        error_log       /var/log/nginx/example_com.error.log error;

        #Remove HTML Extension
        rewrite ^(/.*)\.html(\?.*)?$  permanent;

        # Remove trailing slash
        rewrite ^/(.*)/$ / permanent;

        # Make sure Nginx knows what files to look for, and for that we use the try_files directive.
        # Look for a file with the current $uri and an .html extension, and if no file exists, 
        # check for a directory with that name and serve the index. Otherwise, render a 404 error.
        try_files $uri/index.html $uri.html $uri/ $uri =404;

        location = /form/contact.php {
                deny all;
                return 404;
        }

        # Custom error pages
        set $error404 /en/404.html;

        location /ca {
            set $error404 /ca/404.html;
        }

        error_page 404 =404 $error404;


        location = /form/contact {
                try_files $uri.php =404;

                include /etc/nginx/fastcgi_params;
                fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
                send_timeout 1800;
                fastcgi_read_timeout 1800;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
        }

        location ~ /\.ht {
            deny  all;
        }

        location ~ /(config) {
                deny all;
                return 404;
        }
    }

你不能那样使用位置块,你会破坏所有其他位置块。有关详细信息,请参阅 how nginx processes a request

有一个更简单的方法。使用命名位置处理 404 响应,只需将原始 URI 重写为所需的错误页面即可。

例如:

error_page 404 @error404;

location @error404 {
    rewrite ^/(en|es|ca) //404.html last;
    rewrite ^ /en/404.html last;
}

只需在服务器内部的配置中添加下面这行错误页面重定向即可。

error_page 404 https://www.example.com/404-page.html;

这解决了我的问题
