Axios, POST request to Flask

Question

I try to make a POST to a flask server using axios:

var config = { headers: {  
                      \'Content-Type\': \'application/json\',
                        


        

Answer 1

You need to add CORS support to your Flask app. See a related threat here: Flask-CORS not working for POST, but working for GET. A popular CORS extension for Flask can be found here: https://flask-cors.readthedocs.io/en/latest/.
