nginx api/index.php/explorer url gives 404 error

Question

My problem is that I can not open a url which looks like this: http://myhost.mydomain.xx/.../api/index.php/explorer (This is actualy the webservice url for dolibarr crm, but thats not that important) I am using nginx with php_fastcgi. Here is the relevant part of my default site configuration from nginx:

server {
listen 80 default_server;
server_name myhost.mydomain.xx;
root /var/www/html;
index index.php index.html;
error_log     /var/log/nginx/myhost_error.log debug;
location ~ \.php$ {
#   location ~* \.php(/|$) {
#   location ~ \.php {
    try_files $uri =404;
#       try_files $uri /index.php/$uri /index.php/$uri&$args /index.php?q=$uri&$args;
#       try_files $uri /index.php/$uri;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_read_timeout 600;
    include fastcgi_params;
    access_log /var/log/nginx/php-access.log;
    error_log /var/log/nginx/php-error.log debug;
}
#   return 301 https://$host$request_uri;
    if ($lan-ip = yes) {
        set $allowed_country yes;
    }
    if ($allowed_country = no) {
        return 404;
    }

}

As you can see I have tried a couple of try_files and a couple of location directives as I googled different keywords to try to find an answer. But none works. Which is not suprising for me, because I don't really know what I am doing with the different setups.

The closest I got was with the original settings:

try_files $uri =404;

and

location ~ \.php$

but this way nginx "thinks" that the url I am trying to open is a directory.

(I have copied the nginx debug error log here for reference, maybe it's not unnecessary)

My feeling is that the location directive is badly formed, but I have to admit the regex escapes me totally.

My question is what is the correct form of a location directive, so nginx does not think that the url is a directory?

Answer 1

The path info needs to be split from the URI (using the fastcgi_split_path_info directive) before the script name can be evaluated. So try_files cannot be used here, and the unfashionable if block needs to be used instead.

From the official example:

location ~ [^/]\.php(/|$) {
    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
    if (!-f $document_root$fastcgi_script_name) {
        return 404;
    }
    ...
}

See this document for details.

Answer 2

I leave this in case it helps anyone. you must configure as follows. I am also using dolibarr and had the same problem

location / {

    try_files $uri $uri/ /index.php?$query_string;
    

    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        if (!-f $document_root$fastcgi_script_name) {
            return  404;
        }

        fastcgi_pass    127.0.0.1:9002;
        fastcgi_index   index.php;
        include         /etc/nginx/fastcgi_params;
    }
}
