Authorization-code error Azureauth R package

Question

I am running a R script on rstudio ide of posit workbench which hosted on Azure VM RHEL 8 Linux server. I am trying to connect to azure application using Azureauth R package using Authorization-code method. When I run the script, I get local host refused to connect but the same Works for device-code method of the Azureauth R package.

The below is R code which I have tried to connect azure application.

R Script -

library(AzureAuth) 
redirect <- "http://localhost:1410" token <- AzureAuth::get_azure_token( "My_Resource", 
"My_Tenant_ID", 
"My_App_ID", 
use_cache = FALSE, 
auth_type = "authorization_code", authorize_args=list(redirect_uri=redirect) )

Error - localhost refused to connect**

But same code works via device-code method of azureauth r package

auth_type = "device_code"

I tried to open the new popped browser URL which gives out localhost refused to connect error via a Linux terminal command curl pop_browser_url and this is authenticating without any error .

Code with device code method works -

library(AzureAuth) redirect <- "http://localhost:1410" token <- AzureAuth::get_azure_token( "My_Resource", "My_Tenant_ID", "My_App_ID", use_cache = FALSE, auth_type = "device_code", authorize_args=list(redirect_uri=redirect) )

Can you share your device_code folw code in the question? — Dasari Kamali

I successfully retrieved the access token from Azure AD using Authorization_code flow with AzureAuth package in R.

I added the below URL in the Azure AD app's redirect URI under Web as shown below.

http://localhost:1410

enter image description here

Code :

library(AzureAuth)
library(httr)
library(jsonlite)

redirect <- "http://localhost:1410"    
resource <- "https://graph.microsoft.com"  
tenant_id <- "<tenantID>" 
app_id <- "<appID>" 

token <- AzureAuth::get_azure_token(
  resource = resource,
  tenant = tenant_id,
  app = app_id,
  use_cache = FALSE,  
  auth_type = "authorization_code",
  authorize_args = list(redirect_uri = redirect)
)

print(token)

cat("Access Token: ", token$credentials$access_token, "\n")

Output :

The following code ran successfully and redirect to the below page in browser to logged in to my Azure account.

I authenticated successfully after logged in as shown below.
