Nginx location index trouble

Question

I have troubles with nginx location block.

location /myApp/api/account/tutorialPage { alias /data/www/; index tutorial.html; } 

if a have strict match - all is fine, a have access to my tutorial.html.
But i want every link that contains /tutorialPage would lead to tutorial.html.
So i made next location:

location ~ /tutorialPage { alias /data/www/; index tutorial.html; } 

It must be something like "if link contains /tutorialPage than go to tutorial.html". But i have 403 error.

[error] 10148#0: *65346 directory index of "/data/www" is forbidden, client: 194.183.181.44, server: , request: "GET /myApp/api/account/tutorialPage/ HTTP/1.1", host: "my.domain.com", referrer: "https://my.domain.com/"

I have double checked that data/www dir is has chmod 755 (e.g can be read by enyone)

----UPD

Example of locations that works

 location ~ /tutorialPage\z { rewrite ^/.* /tutorial redirect; } location /tutorial { alias /data/www; index tutorial.html; } 

Answer 1

You need to internally rewrite the URI:

location ~ /tutorialPage { rewrite ^ /tutorial.html last; } 

The index directive determines the default action when encountering a directory, which is not the case here.
