Error when cookies contain double quotes

[na--]

While testing something else, I stumbled on a small bug with double quotes in cookie values... The following code:

import http from 'k6/http';

export default function () {
	let resp = http.get("https://httpbingo.org/cookies", {
		"cookies": {
			"test": "\""
		},
	})
	console.log(resp.body);
}

produces this... warning?:

2018/07/16 10:18:33 net/http: invalid byte '"' in Cookie.Value; dropping invalid bytes

It seems that for some reason, the Go standard library logs this directly, which is super annoying... Skimming some golang issues, it's not exactly clear how we should escape those values...

Hello,

Same problem for me !

The application I test uses double quoted cookies values with separators + uppercase headers

Cookie: foo-boa="DATA-NET-CMP:1234564:123456789789798AEZEAZEA:zzzX"
SPECIFIC-HEADER=jfdislfjsdi

I ended up patching net/* go sources to make it permissive :-(

• Removed cookie/headers sanitization .

Although it' dirty hacks, I didn't find any elegant way to do it.

Yeah, when I posted this issue I skimmed a bunch of golang github issues and discussions and I don't think I saw a nice way to work around this...

you can also get the cookie directly from the r.header["cookie"] and parse it yourself but it's not elegant neither.

Hello All,
Is there any workaround to this?
I am currently blocked because of this issue. We need to set a cookie in our performance test script whose value contains double quotes and its getting escaped :(

Try URL encoding the string as a workaround. Eg:

http.cookieJar().set('https://www.google.com', 'my_cookie', encodeURIComponent("\"I have quotes!\""));
