SCIM filter and db implementation

[amir4895]

Hi all ,
I'm writing SCIM integration to OKTA ,
As far as i understand SCIM mechanism with OKTA:
https://developer.okta.com/docs/reference/scim/scim-20/#scim-user-operations

Once user is being provisioned (created or update or delete) SCIM send "Get" & GetAll requests to check states, i'm using this repo and i'm seeing in the logs few requests prior to the actual "create" / "replace "

getAll /scim/Users?filter=userName%20eq%20%22Name%40%22&startIndex=1&count=100"
get scim/Users/id"

as far as i understand the get all should find the specific user by unique key that is being configured in the IDP (okta here)
and if the user found the SCIM call for get to get the user detail if not calling create

my question is:
i need to query my db with the "filter " content from the getAll request in order to return the IDP the results

I saw that in the ListRequestParams struct we set "filter" attribute with the content of the filter from the query params but it's a complicated struct, and i didn't find easy way to use it , is there any recommended package in Go that can "translate" the Expression into simple literals in String ?

for example "userName%20eq%20%22Name%40%22&"

left = username
comparator = eq
right = name

I searched over Github and didn't find something suitable
tnx

https://github.com/scim2/filter-parser provides parsing for filter expressions, String allows you to stringify expressions again.

Not sure I follow, how I can use the String or the filter-parser
considering i'm having this function signature :
func (exp *scimUserHandler) GetAll(r *http.Request, params scim.ListRequestParams) (scim.Page, error)
How can i use the parser? :

when i trying to use param.filter i don't see any String function.

i was expecting to have attributes as :
right
left
operator
or something like that cab u attach example?
tnx

You would want to check the type of Expression in params.Filter.
For userName eq Name you would have an AttributeExpression with provides you with the attribute, operator and compare value.
