Issue #20 added url constructor to JwkProviderBuilder #22

darthvalinor · 2018-04-06T23:06:55Z

URL constructor added to JwkProviderBuilder, which allows to customize the url to get JWKS. Before, it could only be <domain>/.well-known/jwks.json, now it can be <domain>/sub/path/.well-known/jwks.json
In case url is null IllegalStateException is thrown, so the behavior is similar to the String constructor
Unfortunately, I didn't find a good way to move JwkProviderBuilder.normalizeDomain to UrlJwkProvider keeping the same behavior
Slight fixes for JavaDocs
Please, let me know if more tests required

Thanks for the contribution!
My only strong opinion is that I see no use on having a separate class for handling the construction of the URL from the string domain (that factory class). I'd keep that logic in the original class private method.

Unfortunately, I didn't find a good way to move JwkProviderBuilder.normalizeDomain to UrlJwkProvider keeping the same behavior

Regarding this, the JwkProviderBuilder shouldn't have that normalizeDomain method. That should be part of the URLJwKProvider because it already handles "that type of data". If you can make those 2 changes, I'll then review javadoc or error messages and merge it. 👍

@lbalmaceda thanks for the review!
I updated the pull-request with your points.

The added class removed. The URL creation returned to URLJwKProvider.urlForDomain as package-private and reused in JwkProviderBuilder(String).
Domain normalization had to be moved to URLJwKProvider which caused a change in behavior: JwkProviderBuilder(String) no longer fails on non-normilized domains. The according test removed. Hopefully, it's acceptable.
Tests and JavaDocs adjusted accordingly.
Also need your opinion on IllegalStateException in JwkProviderBuilder vs IllegalArgumentException in URLJwKProvider.

When can we have this on Maven Central?

Mostly javadoc changes.

-     * @param domain domain where to look for the jwks.json file
+     * Creates a provider that loads from the given domain's well-known directory.
+     * <br>If the protocol (http or https) is not provided then https is used by default
+     * (some.domain -> "https://" + some.domain + {@value #WELL_KNOWN_JWKS_PATH}).


use {DOMAIN} instead of "some.domain". You can also say something like "for example, when -domain- is -acme.com- the jwks url that will be used is -https://acme.com/.well-known/jwks.json"

don't mention the constant. Use "/.well-known/jwks.json" instead, since the constant is package private anyway and users won't see it.

the JavaDoc fixed and alligned with JwkProviderBuilder(String)

Probably better to import the required ones only

This whole "before" method is no longer being used generically. It's only used in shouldReturnSingleJwkById. Feel free to remove this and the provider field.

Made some cleanup

This line hasn't been tested. Telling by the docs it will throw "if no protocol is specified, or an unknown protocol is found, or spec is null."

being "protocol" part of the URL (first param) and

being "spec" the well-known constant, which is never null.

So protocol could be any of http, https, ftp, file, and jar. We are adding https if the domain doesn't begin with http, so those 2 protocols are covered. And because we're enforcing any of those 2, this should be a valid value too. I don't see how to trick our logic in a test to make it fail in this line. If you happen to find something, feel free to add it. But don't worry if you can't that's OK anyway and we should catch it here. (which again, should never be called).

covered with a test with "httptest://..."

@cocojoe I really like this to be merged. Can I have your blessing?

@lbalmaceda If you're happy, I'm happy.

darthvalinor · 2018-04-23T20:30:17Z

I accidently made a comment fix and then reverted it. In order to keep the history cleaner, I can rebase. What do you think?

lbalmaceda · 2018-04-23T20:43:15Z

As you want, I can also "squash and merge" and keep 1 single commit for the entire PR. No worries. I'll merge this one and try to release by tomorrow.
