How to enable CORS in python

Question

Let me start this with, I do not know python, I\'ve had maybe 1 day going through the python tutorials. The situation is this. I have an angular app that has a python app host

Answer 1

For Python with CGI, I found this to work:

print '''Access-Control-Allow-Origin: *\r\n''',
print '''Content-Type: text/html\r\n'''

Don't forget to enable CORS on the other side as well, e.g., JavaScript jQuery:

    $.ajax({ url: URL, 
             type: "GET", 
             crossDomain: true, 
             dataType: "text", etc, etc

Answer 2

Here it is. Just add this to the application right at the beginning:

def application(environ, start_response):
  if environ['REQUEST_METHOD'] == 'OPTIONS':
    start_response(
      '200 OK',
      [
        ('Content-Type', 'application/json'),
        ('Access-Control-Allow-Origin', '*'),
        ('Access-Control-Allow-Headers', 'Authorization, Content-Type'),
        ('Access-Control-Allow-Methods', 'POST'),
      ]
    )
    return ''
