CORS details

• Content-Type: application/json means a request can no longer be considered a CORS simple request, hence a CORS preflight request is triggered
• https://auth0.com/blog/cors-tutorial-a-guide-to-cross-origin-resource-sharing/
• seems that OPTIONS is not supported by AllowedMethods
• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-s3-bucket-cors-corsrule.html#cfn-s3-bucket-cors-corsrule-allowedmethods
• however
• https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html
• "The rule also allows all headers in a preflight OPTIONS request through the Access-Control-Request-Headers header. In response to preflight OPTIONS requests, Amazon S3 returns requested headers"
• this suggests that specifying Content-Type: application/json should be okay

dependencies

• create an app.props file as follows -

AppName=jhw-hello-world

running the example

jhw

run

python hello_drumsynth_1.py
python hello_drumsynth_2.py
