静默重写URL到NGINX中的子子目录

Question

I am wondering if someone can please help me with something that I am racking my brain with. I have a folder structure like this;

/var/www/<user>/<user>/

So to see the files currently with NGINX I need to naviagte to;

https://<host>/<user>/<user>

What I want to do is make it so I can navigate to the following and it is re-written silently in the backend.

https://<host>/<user>/

To achieve this, I have written the following rule

location ~ ^/(.*)/(.*)$ {
    index index.html;
    try_files $uri /$1/$uri/index.html /$1/$uri;
}

It seemed to work once but since it unfortunately keeps rewriting in a continuous loop. I've tried a few things and understand why it loops but I cannot work out how to stop it.

Now, you may be wondering why have this folder structure. It's a long story but basically I want a user to only have access to their files and with Chroot (for sftp) the root dir must be owned by root so it needs a subdirectory to make it work due to permissions.

Answer 1

So if anyone has this issue in future, the problem what that the first match ($1) was matching incorrectly, it contained everything in between the slashes. So it would match like this;

/<user>/
$1 = <user>

/<user>/<subdir>
$1 = /<user>/<subdir>/

/<user>/<subdir>/<file>
$1 = /<user>/<subdir>/

To fix this so that $1 was always only the first slash part I changed the NGINX config to this:

location ~ /([^/]*)/(.*)?$ {
    try_files $uri /$1/$1/$2 /$1/$1/$2/index.html /$1/$1/index.html;
}

This will match like the following:

/<user>/
$1 = <user>

/<user>/<subdir>
$1 = <user>

/<user>/<subdir>/<file>
$1 = <user>

Now it all matches correctly and works fine. I hope that this someday helps someone else with the same issue.
