I"m running into a weird CORS issue right now.
Here"s the error message:
XMLHttpRequest cannot load http://localhost:8666/routeREST/select?q=[...] Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin
Any thought on what could be the problem?
And... the port was the problem. Thanks for your answers :)
If anyone is using a Python bottle server as well, you can follow the answer given on this post to solve the CORS issue: Bottle Py: Enabling CORS for jQuery AJAX requests
It is only considered to be the same if the protocol, host and port is the same: Same Origin Policy
You need to add Access-Control-Allow-Origin as a header in your response. To allow everyone (you should probably NOT do that):
If you need to support multiple origins (for example both
www.example.com), set the
Access-Control-Allow-Origin in your reply to the value of the
Origin-header from the request (after you verified that the Origin is white-listed.)
Also note that some requests send a preflight-request, with an OPTION-method, so if you write your own code you must handle those requests too. See Mozilla for examples.
