Status 404 on valid rewrite, index handler expected - nginx

Question

The location / have a #rewriteIt but something is worg...
Fresh installation of NGINX into UBUNTU 16 LTS, all apt standard.
NGINX is ignoring my rewrite, why? how to fix for example.com/foo redirect to test.php?
Testing status and dynamic pages, all fine except the rewrite:
OK http://example.com
BUG (is not for 404) http://example.com/foo
OK http://example.com/?foo
OK http://example.com/index.php
OK http://example.com/test.php
With scripts
example.com
server {
server_name example.com www.example.com;
root /var/www/example.com/;
index index.php index.html index.htm;
location / { # ignoring here?
try_files $uri $uri/ #rewriteIt =404;
}
location #rewriteIt { # something wrong here?
rewrite ^/?([a-zA-Z0-9\-]+)/?$ test.php?obj=$1 last;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
}
Same when change to try_files $uri $uri/ #rewriteIt;.
default
server {
listen 80; ## listen for ipv4; this line is default and implied
listen [::]:80 default_server ipv6only=on; ## listen for ipv6
root /var/www/html;
index index.php index.html index.htm index.nginx-debian.html;
server_name localhost;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
}

Answer 1

The named location needs to be the last parameter of the try_files statement, replacing the =404 term. See this document for details.
There is also a second error. All URIs in nginx begin with a leading /, so the rewrite statement should specify /test.php?obj=$1 as the target.
