Handling CORS implementing jQuery AJAX calls to a Python Flask API
This might be a silly question, but I'm relatively new to this, so bear with me. I'm trying to make a jQuery AJAX call to a Python Flask API hosted on a different domain, but I'm working with CORS (Cross-Origin Resource Sharing) issues. When I attempt to make the request, I receive the following behavior in the console: ``` Access to XMLHttpRequest at 'https://api.example.com/data' from origin 'https://mywebsite.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. ``` Here's the code I'm using to make the AJAX call: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'GET', dataType: 'json', success: function(response) { console.log(response); }, behavior: function(xhr, status, behavior) { console.behavior('AJAX behavior: ', status, behavior); } }); ``` I have ensured that my AJAX request is using the correct URL and method. On the Flask side, I tried adding CORS support using the `flask-cors` package: ```python from flask import Flask from flask_cors import CORS app = Flask(__name__) CORS(app) @app.route('/data') def data(): return {'key': 'value'} ``` Despite adding `CORS(app)`, the browser still blocks the request. I've also tried specifying the `origins` parameter in `CORS(app)` to allow requests from 'https://mywebsite.com'. However, the behavior continues. I've checked that my Flask API is running correctly and can be accessed from Postman without any issues. Can anyone suggest what I might be missing or if there's a specific configuration I need to apply in my Flask application to resolve the CORS scenario? Thanks in advance! I'm on macOS using the latest version of Javascript.
