Hi there, how can I pass a cookie at Ktor client headers?
I am trying the below code

header("Cookie", cookie)

but Ktor seems to ignore it.

[Aleksei Tirman [JB]]

There is the cookie function to send Cookies. You can find an example in the documentation.

Use the cookie() function

@Aleksei Tirman [JB] the link is a 404

[Aleksei Tirman [JB]]

Oops sorry, fixed it.

[ptsiogas]

I am using cookie() like this with no result:

client.get("myEndpoint") {
            cookie(name = "JSESSIONID", value = "uLOgaxWu7uF4tic5sBrXkBzvxB-rDWScF-fTDvB6Mj4F243gvhdo!-128011973")
}

I am doing something wrong?

[Aleksei Tirman [JB]]

Seems correct. The following code works as expected:

val client = HttpClient(CIO)

val r = client.get<String>("<https://httpbin.org/get>") {
    cookie(name = "JSESSIONID", value = "uLOgaxWu7uF4tic5sBrXkBzvxB-rDWScF-fTDvB6Mj4F243gvhdo!-128011973")
}

println(r)

How do you check the result?

[ptsiogas]

With 2 ways:
1. Checking the logs
2. Getting an error from the API call

[ptsiogas]

btw I am testing it from Android client

[Aleksei Tirman [JB]]

The same code I've posted works on the Android emulator with the Android engine. Could you please check the actual presence of a Cookie header in the Wireshark?

[ptsiogas]

Wireshark shows the same logs

[ptsiogas]

Very strange

[ptsiogas]

@Aleksei Tirman [JB] could you plz show me your logs in order to see how it is appearing?

[Aleksei Tirman [JB]]

GET / HTTP/1.1

[Aleksei Tirman [JB]]

I added android:usesCleartextTraffic="true" to make an insecure connection.

[ptsiogas]

I managed to send it when I passed it like this:

defaultRequest {
                cookie(
                    "JSESSIONID",
                    "uLOgaxWu7uF4tic5sBrXkBzvxB-rDWScF-fTDvB6Mj4F243gvhdo!-128011973"
                )
            }

hm it appears like it has urlEnconding

JSESSIONID=uLOgaxWu7uF4tic5sBrXkBzvxB%2DrDWScF%2DfTDvB6Mj4F243gvhdo%21%2D128011973

@Aleksei Tirman [JB] I have a clear status of the issue I am dealing with now.

If I set:

install(HttpCookies) {
                storage = AcceptAllCookiesStorage()
            }

then all my “custom” cookies are being ignored.

If I remove that then everything plays well.
The thing is that I need to initially read the cookie from an API call and the AcceptAllCookiesStorage() declaration seems to me that is necessary.

[Aleksei Tirman [JB]]

@ptsiogas seems like this behavior is wrong. Cookies are removed because of this line. I've created an issue KTOR-3105 to address this problem.
