Using the Azure Databricks R Shiny example, I am easily able to instantiate a R Shiny web front session. The URL that is provided by Databricks provides the proxy session that allows my targeted audience to directly access my `R Shiny` app using that URL.
I want to obtain the user_id via that is currently accessing directly to my R Shiny web session context. How do I do that? Does Azure Databricks proxy wrapper (to my R Shiny web app) provides any authentication or authorization using the physical access token of that particular user?
Please don't get confused with the following, which promptly returns the user_id of my Databricks compute session that is hosting my R Shiny web app and that is not what I am after.
library(SparkR)
get_current_user <- SparkR::sql("SELECT current_user()")
user_df <- as.data.frame(get_current_user)
current_user <- user_df[1,1]
print(current_user)
# [1] "dbx_user@fqdn.com"
typeof(current_user)
# [1] "character"
