### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

# All other users may do anything other than call PutObject
allow {
 input.action != "s3:PutObject"

Kemudian anda bisa memiliki path `/users/{user_id}` untuk mendapatkan data user tertentu melalui user ID.

karena *operasi path* dievaluasi melalui urutan, anda harus memastikan path untuk `/users/me` dideklarasikan sebelum `/user/{user_id}`:
