Keycloak user attributes with multiple values (list)

问题

I'm having a Keycloak use case where single user may have multiple customer numbers. These customer numbers would need to be sent to service provider / client and also be easily updated by administrators. Some users may have hundreds of customer numbers. Currently I'm using single user attribute named "customerNumbers" where the customer numbers are separated by comma but I'd like:

1. To offer the administrators possibility to see each customer number in its own field
2. To send the customer numbers as an JSON array instead of comma separated claim

So instead of this:

I'd like something like this:

And instead of this

"customers": {
"customerNumbers": "140661,140662"
},

I'd like something like this:

"customers": [
    {"customerNumber": "140661"},
    {"customerNumber": "140662"}
],

How should one approach this kind of situation?

回答1:

You need to add your values in the user attributes like this [{"customerNumber": "140661"}, {"customerNumber": "140662"}]

ie [Keycloak user management, attributes tab][1]

your client mapper will need be like this (i think i tried every other option)
