Description

APISIX now does not allow the requests with empty adminKey to access Admin API except 127.0.0.0/24.

The user can allow this by the configuration below.

deployment:
  admin:
    admin_key_required: false    # Default value is true

Fixes #9071

If this option is turned on, can we provide some hints, otherwise there may be security risks
Do we need to add this inspection to the inspection script? @leslie-tsang

Yes for sure, need to log it in error log as well.

CC @monkeyDluffy6017 Key hints are added.

Besides, I have changed the implementation details according to @moonming 's advice.

If APISIX_ALLOW_NONE_AUTHENTICATION=true, all the requests can access the Admin API without adminKey, no matter whether the user config it.

Why are there duplicate codes?

Do you mean that hint appears in both stdout and log?

  1. opt.lua checks if allow_admin in config.yaml is correct before APISIX starts. We need to bypass the adminKey check here.
  2. init.lua checks the adminKey when accessing the Admin API (after APISIX starts). We need to bypass check_token, too.

That's why I have implemented bypass-logic in two different stage.(before and after the start).

In other words, opt.lua does a static check on the configuration file (if it is not 127.0.0.0/24 and the adminKey is empty, APISIX will not start).

We also have to bypass the checks here.

If there is repeated code, then it needs to be abstracted into a function

It seems that the only code common to both sides is:

if conf.deployment.admin.admin_key_required == false then
 print / log
end

Actually the output approach is different (before APISIX starting is print, after starting is log).

So IMHO, merge this two part to one function is unnecessary, because the common part is too simple (only with common part conf.deployment.admin.admin_key_required == false )
