[chuck2098]

Hi, I have a question. I'm trying to make a http request using this package but i get thie error: How can I resolve this issue? In local, with emulator device is ok but on web I have this problem.

P.S. I setted also the header "Access-Control-Allow-Origin": "*" Thanks a lot.

I have this error too.

update: I add headers and solved.

res.headers.add('Access-Control-Allow-Origin', '*'); res.headers.add('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT, DELETE, HEAD');

This problem only occurs when building a web app and hosting from a web server (not localhost). Can the http package somehow wrap this request in a "form" when building the web app so that it avoids the CORS error?

In my case, I had to create a service to do the request from. It wouldn't work directly from a web page.

I have the same Problem and can't solve it at the moment. The library example does not work either. (for web)
