How to get logged in user name/email in the databricks streamlit app?

[satniks_o]

I have created a Databricks App using streamlit and able to deploy and use it successfully.

I need to get the user name/email address of the logged in user and display in the streamlit app. Is this possible?

If not possible at the moment, any roadmap for adding this feature?

regards,

Yes, it is possible to retrieve and display the username or email address of the logged-in user in a Streamlit app deployed on Databricks. This can be achieved through two primary approaches:

1. Using "st.experimental_user" in streamlit.

import streamlit as st

# Access the user's email

user_email = st.experimental_user.get("email", "Unknown User")

# Display the email in the app st.write(f"Logged in as: {user_email}")

2. Using HTTP Headers in Databricks Apps.

import os

import streamlit as st

# Access headers passed by Databricks Apps

user_email = os.getenv("X-Forwarded-Email", "Unknown User")

# Display the user's email

st.write(f"Logged in as: {user_email}")

Hope this helps. Cheers, Louis.

X-Forwarded-Email worked. I assume you mean using st.context.headers.get() instead of os.getenv().

user_email = st.context.headers.get("X-Forwarded-Email")

st.write(f"email: {user_email}")

Thanks @BigRoux  and @Shannon_O  for your response.

I tried st.experimental_user.get() API but it gives me hardcoded response as test@example.com 

Suggestion to use X-Forwarded-Email header worked and I got correct email address. Thanks for your help. I am unblocked now.

I have also tried to deploy a streamlit app, however I was not able to deploy it.
