Hello,
I have a similar issue. Added this piece of code in my python application
but I see still get the CORS error. I thought this code will be generic for
all the request. Should I add request.method=options for each and every
POST method?
def add_cors_headers_response_callback(event):
def cors_headers(request, response):
response.headers['Access-Control-Allow-Origin'] = '*'
response.headers['Access-Control-Allow-Methods'] =
'POST,GET,DELETE,PUT,OPTIONS'
response.headers['Access-Control-Allow-Headers'] =
'access-control-allow-origin,content-type'
response.headers['Access-Control-Allow-Credentials'] = 'true'
event.request.add_response_callback(cors_headers)
def main(global_config, **settings):
""" This function returns a Pyramid WSGI application.
"""
with Configurator(settings=settings) as config:
config.include('pyramid_jinja2')
config.set_security_policy(
SecurityPolicy(
secret=settings['invest_web.secret']
),
)
config.add_subscriber(add_cors_headers_response_callback, NewRequest)
config.include('.routes')
config.include('.models')
config.scan()
return config.make_wsgi_app()
