Nginx setting wrong content type - php

Question

I have an online web server where I have deployed multiple applications and they all have to share the domain, so my nginx config is a bit messy. The last time I changed it, the PHP files didn't load getting the error ("access denied to file") so I had to do some changes, now the config for one of the applications is like this:
location ^~ /vuelos_baratos {
root /home/gonzalo;
try_files $uri $uri/ /$uri/index.php /index.php$is_args$args $uri/index.php =404;
#root /usr/share/nginx/html;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
include /etc/nginx/mime.types;
autoindex on;
}
and the urls of this application are like this:
mydomain.com/vuelos_baratos/index.php
mydomain.com/vuelos_baratos/style.css
...
and so on.
And the PHP files and everything is working fine, except that If I try to acces:
mydomain.com/vuelos_baratos/image.png
I get the binary data of the image, I discovered that that is because the headers for all files under "vuelos_baratos" are set to type: text/html
How can I fix this?

Answer 1

I don't think that nginx is responsible for determining the content type in your current configuration, as you pass everything to php-fpm.
You could divide the static and dynamic sections into separate locations, for example:
location ^~ /vuelos_baratos {
include /etc/nginx/mime.types;
root /home/gonzalo;
index index.php;
try_files $uri $uri/ /index.php$is_args$args;
location ~ \.php$ {
try_files $uri =404;
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_param SCRIPT_FILENAME $request_filename;
}
}
Which should mean that /vuelos_baratos/image.png is processed by nginx and that /etc/nginx/mime.types is used to determine the Content Type.
