No 'Access-Control-Allow-Origin' header is present on the requested resource. from mobile services

问题

I created a simple vanilla ToDo from azure mobile template to test the service but don't seem to work correctly. I can connect to https://phonegapwil.azure-mobile.net from localhost with mobile services but not after I published site, http://phonegapwil.azurewebsites.net/

error message I get: XMLHttpRequest cannot load https://phonegapwil.azure-mobile.net/tables/todoitem?$filter=(complete%20eq%20false). No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://phonegapwil.azurewebsites.net' is therefore not allowed access. The response had HTTP status code 400.

I also tried "*" for the CORS but no go.

Any ideas? Thanks

Thanks for your reply @phillipv. I used "*" but still didn't work. I used .net as my mobile service back-end and that was the problem. Seems like they have a bug. I recreated this using node back-end and worked without an issue.

come on Microsoft

I saw a nuget fix here cors not working with azure mobile service .net backend
