What I do is to write a customized HTTPRequestHandler. I add a do-OPTIONS method inside MyHandler to tell browser my server support CORS. This is done by sending headers Access-Control-Allow-Origin, Access-Control-Allow-Methods and Access-Control-Allow-Headers. Also, I add a "self.send_header('Access-Control-Allow-Origin', '*')" statement in do_GET method.

class MyHandler(BaseHTTPRequestHandler):
    def do_OPTIONS(self):           
        self.send_response(200, "ok")       
        self.send_header('Access-Control-Allow-Origin', '*')                
        self.send_header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS')
        self.send_header("Access-Control-Allow-Headers", "X-Requested-With")        

    def do_GET(self):           
        self.send_response(200)
        self.send_header('Access-Control-Allow-Origin', '*')
        self.send_header('Content-type',    'text/html')                                    
        self.end_headers()              
        self.wfile.write("Hello world!")
        self.connection.shutdown(1)
