Ajax Question

Cross-Domain Ajax Requests WSO2 IS

curl -v -X POST -H "Authorization: Basic <base64 encoded client id:client secret value>" -k -d "grant_type=password&username=<username>&password=<password>" -H "Content-Type:application/x-www-form-urlencoded" https://localhost:9443/oauth2/token


This 'curl' command works perfectly. But when try to call it through ajax:

type: 'POST',
data: 'grant_type=password&username=admin&password=admin',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': 'Basic Z0hLUlA3eThYTmJydl9JR1pJemxDQ1VJQlo0YTozT2VLaUlmUVViMk1yZzZ2YU5uQVFsWFpDU29h'
url: 'https://localhost:9443/oauth2/token',
success: function(data) {

I got this error: "XMLHttpRequest cannot load https://localhost:9443/oauth2/token. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access."

How can I configure WSO2 IS to deal with it? Or is there an alternetive for this?

There is a similar issue with WSO2 API Manager (WSO2 API Manager CORS). But there is no such directory '/repository/deployment/server/synapse-configs/' in WSO2 IS.

This is the expected behaviour when cross origin resource sharing (CORS) is not enabled on Identity Server. In fact you can enable CORS for Identity Server. Check [1] on how to do it.
