Cookie headers are received but not shown in devtools when using 'http'

[yoshuawuyts]

@zcbenz do you know if electron blocks the Set-Cookie header by default? Responses that carry this in the browser don't seem to have it in electron.

I read through the source, couldn't find any code that would point to that, but checking just in case this is true. Possibly related / of use to #1606.

I've created a repro for this: https://github.com/yoshuawuyts/electron-cookie-issues-repro.

It appears electron is indeed blocking cookie related headers.

update: 05/06/2014: It appears the only bug in electron is that cookie related headers aren't shown when fetching data.

electron blocks cookie headers

Using OSX@10.10.2 and electron@0.27.2 pulled in through electron-prebuilt.

Steps to reproduce (repro)

• setup electron to load an index.html that loads client.js
• perform an XHR request from client.js to a server.js that sets the Set-Cookie header

Actual results

• no cookie headers are received cookie headers are not shown in devtools

Expected results

• cookie headers are received cookie headers are shown in devtools
• cookies are not stored (electron-cookies provides a workaround)

Thanks for the detailed information. I can say that the Set-Cookie header is actually worked. You can view Cookies in Resources panel of dev-tool, then you will find the cookies.

I have no much idea about why dev-tools doesn't show the cookies header here, it might be a bug of dev-tools.

@hokein I'm not seeing any cookies in there, both with electron-cookies enabled and disabled.

edit: also tried the --enable-file-cookies flag, but it doesn't change anything.

Looks like you are loading the local file, are you sure you have sent the correct header?

In your reproduced repo, it actually works, see:

You were right, it was a header issue. Incidentally window.fetch doesn't support cookies so I had went with the nets module instead. The cookie headers not showing up in the request window is still a bug though, so I'll be updating the issue to only reflect that. Thanks for coming back to me so fast & helping me resolve my issues. 🎉

edit: I've also updated the repro with the solution in the README so any future adventurers that stumble into it know what to do.

Update: due to #1574 nets uses request under the hood rather than xhr. When using xhr (e.g. XMLHTTPRequest) everything related to cookies is blocked and cannot be set. In the repro just require xhr instead to see the requests suddenly be oblivious of cookies.

const nets = require('xhr')

As a remark on the side: I wouldn't have expected that doing XHR requests with cookie authentication would have so many gotchas. I wish the electron client would try to stick as closely to a browser environment as possible, maybe even more than it already does. That way both knowledge and code are made more portable which is beneficial to all. Thanks!
