I've created a Flask app that receives image byte data, saves the image, and displays it on screen. it works fine in a local environment, but when uploaded to pythonanywhere it doesn't seem to even save the file to display on screen anymore. Here is my Flask apps route that is responsible for saving the image
@app.route('/vid', methods=['POST'])
def receive_frame():
try:
frame_data = request.data
# Save the received frame as an image
with open('static/images/received_frame.jpg', 'wb') as f:
f.write(frame_data)
return "Frame received and saved"
except Exception as e:
return f"Error: {e}"
@app.route('/static/images/<filename>')
def serve_image(filename):
return send_from_directory('static/images', filename)
In my HTML I use some js to update the image every so often
<img id="image_display" src="{{ url_for('serve_image', filename='received_frame.jpg') }}">
<script>
function updateImage() {
//reset img src to update it
$('#image_display').attr('src', '/static/images/received_frame.jpg?' + new Date().getTime());
}
setInterval(updateImage, 1000);
</script>
The file layout for my project looks like this
Home
├───mysite
│ └─── templates
│ │ └─── index.html
│ └─── server.py (flask app)
└─── static
└───images
I assume its a problem with how I am handling static files. I think its also worth mentioning that I set a path to Static files in my web tab like this
URL Directory
/static /home/786bg8isdfuy/mysite/static
Dose anyone know how to handle static files with flask on pythonanywhere? thank you.
