Hi Rob,
no the code in the repository the link
refers to is more like administrative tooling for batch importing
configuration into Keycloak for administration purposes.
I'll work on creating an excerpt of the
code that realizes Oauth2 code grant flow with RestXQ and Keycloak
and I'll share by tonight hopefully.
Regards,
Marco.

Based on the following quote from Marco’s mail:

The link above, is that the RESTXQ module Marco’s

Or is there another RESTXQ module?
With kind regards,

If Rob isn't interested, I certain am...
Yes please share

Hi,
I have a question.
Can BaseX make use of an Identity Management
application like Keycloak for Users?
I can?t find anything about it :)

Hi all,
In BaseX, is there a way to get the profile timings
(compile, run, print,
etc.) in the response of a HTTP request via the
Server-Timing header (
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Server-Timing)?
Kind regards,

Hi Rob,
There is no prepackaged module for Keycloak (at
least I?m aware of
none), but you can write your own code with XQuery.
See [1] for an
example how this might look like.
Are you using RESTXQ?
Best,
Christian

A good idea; I?ll think of ways to get this
included. One challenge
might be that the response is streamed to the
client. This means that
when creating the HTTP request headers, it will not
be known yet how
long the evaluation will take (and the time for
evaluation may also
depend on the connection speed). The time for
parsing and compiling
the query should be known at that time, though. ?
Maybe we could
suppress result streaming when timings are
requested.

Hi Christian,
I'm not seeing any exceptions in the console window,
even when enabling the
debug setting. I'm using the AdoptOpenJDK 1.8. I
also have AdoptOpenJDK 11,
but I assume that will have the issue you described.
It's a custom-built jar using Kotlin, built via
gradle.
One thing that it could be is that I'm using Kotlin
objects (not classes),
e.g.:
package test
object Test { fun f(): String = "test" }
and using it like:
declare namespace Test = "java:test.Test";
declare function test:f() as xs:string {
Test::f(Test::INSTANCE())
};
The build.gradle file is simple. It looks something
like this (removing
things like the junit configuration):
-----
buildscript {
ext.kotlin_version = "1.4.32"
ext.kotlin_stdlib = "kotlin-stdlib"
ext.java_version = "1.8"
repositories { mavenCentral() }
dependencies { classpath
"org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" }
}
apply plugin: 'kotlin'
repositories {
mavenCentral()
mavenLocal()
}
compileKotlin { kotlinOptions { jvmTarget =
java_version } }
compileTestKotlin { kotlinOptions { jvmTarget =
java_version } }
dependencies {
implementation
"org.jetbrains.kotlin:$kotlin_stdlib:$kotlin_version"
}
-----
You'll need to copy the kotlin-stdlib-1.4.32.jar
file in addition to the
test.jar file to BaseX's lib directory.
Kind regards,
Reece

Hi Reece,
> You'll need to copy the
kotlin-stdlib-1.4.32.jar file in addition to the
test.jar file to BaseX's lib directory.
Please note that JAR libraries will only be
unregistered after query
evalution if they are moved into the repo directory.
If a library is
copied into the lib directory, it will be added to
the static
classpath.
In the given case, you could probably keep
kotlin-stdlib-1.4.32.jar in
the lib directory, but you?ll need to keep your
development code in
the repository (as described in the Wiki). It?s no
problem, though, to
directly modify the repo code (you don?t have to use
REPO INSTALL or
repo:install for that).
If the problem persists, feel free to send me a
little test.jar, I can
then do further testing.
Hope this helps,
Christian

Hi Christian and Rob,
as the authors of the code you point to we confirm
that interacting with
Keycloak in XQuery and in particular RestXQ is
rather comfortable.
That example is mostly a demonstration code for a
tool that scrapes a
site index and registers sites named gateways as
public clients (in
Oauth2 sense) into a Keycloak instance.
It is a proof of concept (as you can see from the
credentials? :-D) that
has been used as a batch one-time migration in a
particular setting.
We have also a RestXQ module that in combination
with basex:perm
annotations protects access to a GUI implementing
the Oauth2 Code-grant
flow. If Rob is interested we could share.
If there should be any plan of integrating
Oauth2/OIDC flows more
tightly into BaseX we could also be available for
helping out.
Regards,
Marco.
