CORS Missing Allow Origin

[francisguchie]

##Description
Currently, client-side scripts (e.g., JavaScript) are prevented from accessing much of the Web of Linked Data due to "same origin" restrictions implemented in all major Web browsers.
While enabling such access is important for all data, it is especially important for Linked Open Data and related services; without this, our data simply is not open to all clients.
If you have public data which doesn't use require cookie or session based authentication to see, then please consider opening it up for universal JavaScript/browser access.

##Steps to reproduce
Follow the steps in https://github.com/openMF/web-self-service-app#readme to run a web self service server / app
Make sure your fineract server is up and running MifosX 17.07.01 (NOT the LATEST BUILD it has other issues #180)

##Expected Behaviour
Fineract Should be able to allow Cross Origin Resource Sharing or at least a web application request from your allowed server

##Actual Behaviour
looking at the console logs You will get the following

XHRPOSThttps://yourserver/fineract-provider/api/v1/self/authentication?password=password&username=selfserviceuser
CORS Missing Allow Origin

{"timestamp":1633262267311,"status":401,"error":"Unauthorized","message":"User not authorised to use the requested resource."}

##Settings:
Mozilla Firefox
Microsoft Edge

MifosX 17.07.01

Have you seen this https://issues.apache.org/jira/browse/FINERACT-879

[francisguchie]

@BLasan, using this PR #182 I can connect to the latest build with no CORS errors. But look at the new developments #180 (comment)

Cross-Origin Request Blocked:
The Same Origin Policy disallows reading the remote resource at
https://apacheFineractServerDomain-Or-IP/fineract-provider/api/v1/self/clients.
Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 401
I have been faced with this issue a number of times I have also done some amount of reading,

My personal conclusion is that it would be nice to upgrade this repo to Angular since AngularJS has not support for CORS headers

@francisguchie Hi, Is it possible to connect this application to fineract? because, I can't able to login. I got the same error "{"timestamp":1633262267311,"status":401,"error":"Unauthorized","message":"User not authorised to use the requested resource."}"
