如何通过在同一EC2中运行的python-flask网络应用将图像上传到EC2？

Question

I have Python-Flask web-app running inside EC2 which performs a binary image classification. The web-app has a UI which allows the user to select the image.

High Level Architecture:

 1. Select the file to 
    be uploaded using the
    web-app UI

 2. Press the "Classify" button.

 3. Image gets uploaded to EC2.

 4. Perform image classification
    and return the results.

 5. Delete the image.

Could you please guide me on how to upload the image located on my machine to EC2 (Step 3) ?

Answer 1

When you press the "Classify" button, your form on your web-app will pass a multipart form data to the flask application. Then within Python, you'll intercept that and save the file.

Python has a great intro on this here: http://flask.pocoo.org/docs/1.0/patterns/fileuploads/
