trackoor opened a new issue, #583:
URL: https://github.com/apache/casbin-node-casbin/issues/583
`keyGet2` splits `key1` and `key2` on `/` and returns the segment of `key1`
at the same array index as `:pathVar` in `key2`, which returns the wrong
segment when `/*` spans multiple segments and returns `""` when `:pathVar` is
only part of a segment.
Reproduction (`repro.js`):
```js
const { Util } = require("casbin");
console.log(JSON.stringify(Util.keyGet2Func("/orgs/acme/teams/t1/docs/42",
"/orgs/*/docs/:id", "id")));
console.log(JSON.stringify(Util.keyGet2Func("/files/report-7",
"/files/report-:id", "id")));
```
Run with `node repro.js`.
Actual output:
```
"t1"
""
```
Expected output (matching Go Casbin `util.KeyGet2` and
https://casbin.org/docs/function):
```
"42"
"7"
```
Versions tested: `casbin` 5.51.1 and `master` (`152ccd9`) on Node v26.13.0
(compared against Go Casbin v2.135.0).
In `src/util/builtinOperators.ts`, `keyGet2` checks `keyMatch2(key1, key2)`
and then looks up `keys.indexOf(':' + pathVar)` in `key2.match(/[^/]+/g)`
instead of extracting the capture group matched by `:pathVar` (as Go Casbin
does by replacing `:pathVar` with `([^/]+)` and `/*` with `/.*`).
