A distress call for st.file uploader

[zhenjiangyu670]

In the process of uploading files using streamlit, I found that each file handle uploaded has upload_url and delete_url. After concatenating my host and port with them, I passed the postman test and found that these routes exist, but the permissions are not enough. For example, if I use the delete method to access the address of the host port to be joined by delete_url, return the status code 403 and prompt Forbidden, and I want to know how I can access the address of the st.file_uploader component directly to delete this file directly. Ask the boss to solve the confusion.

Hi @zhenjiangyu670

Have you check out the following related threads

Get path from file_uploader()

Other than uploading to cloud, there is also the very useful tempfile module including the NamedTemporaryFileclass. Something along the lines of: from tempfile import NamedTemporaryFile import streamlit as st uploaded_file = st.file_uploader("File upload", type='csv') with NamedTemporaryFile(dir='.', suffix='.csv') as f: f.write(uploaded_file.getbuffer()) your_function_which_takes_a_path(f.name) Should work.

Upload Files to Streamlit App

@tc1 I created an app using the new file upload feature, it allows uploading an image and running object detection on it, as well as adjusting the confidence threshold. As an experiment I developed it using a devcontainer and deployed via docker, and it is working rather nicely. Link below. Cheers [usage]

Hope this helps!
