Flask Return File Given Data URI

Within my flask function I am able to retrieve the data URI (with selenium successfully) using the toDataURL() method on a canvas.

I would like to use the data from the data URI object to send a file in my flask method using the send_file flask method.

Thanks!

Solution

  • After working with it some more here's what solved my problem. I used the datauri package for python.

    Here's a sample route for Flask

    import datauri    
import io
from flask import Flask, send_file

@app.route('/test', methods=["GET"])
def return_file():
    data_uri = "some_data_uri"
    p = datauri.parse(data_uri)
    return send_file(io.BytesIO(p.data), mimetype=p.media_type)
