dart BrowserClient - how to read response headers?

Question

I don't manage to read response headers using browser_client.dart :

import 'package:http/browser_client.dart';


var response =
await client.post(url, headers: {
  'Content-Type': 'application/json',
  'Accept': 'application/json'
}, body: body);
print('Response headers: ${response.headers}');

Thanks for your help.

This works for me. Perhaps the server doesn't send the headers or they are suppressed by the browser because of CORS issues? (`Access-control-allow-headers`, `Access-control-expose-headers`)? — Günter Zöchbauer, Sep 05 '16 at 15:42
Thanks, `Access-control-expose-headers` was missing... It works now! — matth3o, Sep 05 '16 at 15:49

The server needs to allow the browser to expose the headers by listing the headers in the Access-control-expose-headers response header, otherwise you can see them in the browser devtools but when you try to read them in code, the browser will suppress them.
