Nginx configure

My Web Server is Nginx & Apache, I have several ULRs without suffix, for example: https://www.example.com/my-post

Please note that there is no "/" at the end of this URL. Now visiting this URL will directly display the source code of this page. How can I make it display the content of the page?

if you mean that it's a PHP page, you need FPM for nginx to use php.

It's not a PHP page, it's a static page, because an opencart was installed before, and its pages are without / at the end, I deleted opencart now, but there are a few pages that need to be kept, so I created these pages manually

How do I set up so that these pages can display the content, and now visit them only to display the source code

Actually, the FPM  has been installed

If the Web Server is switched to Apache Only, these pages can be displayed normally, but I am using Nginx & Apache now, I think it may be caused by Nginx.

If html is displayed as source code, then the mime type for nginx is messed up.  Check for the default mime types and make sure it's not set to text/plain

This is the Nginx configuration of my domain, where should I modify it?

see if the following corrects the issue:

 location / {
      location ~.*\.(3gp|gif|jpg|jpeg|png|ico|wmv|avi|asf|asx|mpg|mpeg|mp4|pls|mp3|mid|wav|swf|flv|html|htm|txt|js|css|exe|zip|tar|rar|gz|tgz|bz2|uha|7z|doc|docx|xls|xlsx|pdf|iso|woff|ttf|svg|eot|sh|webp)$ {
         default_type "text/html";
         root /home/example/public_html;               
         expires max;
         try_files $uri $uri/ @backend;
      }

I change it in /etc/nginx/conf.d/vhosts/mydomain.com.conf

Then restart Apache and Nginx, but the URL without the / suffix still displays the source code
