Hi, I've been exploring the use of the JSON api with the new HttpClient in Java 11 and guided by this helpful documentation and the linked Python and Java code.

I haven't succeeded in logging in, and my best guess is that it's related to 'Referer'. When I try this:

Code: Select all

HttpRequest request = HttpRequest.newBuilder()
            .uri(URI.create(url))
            .header("Content-Type", "application/json")
            .header("X-CSRFToken", this.token)
            .header("Referer", url)
            .POST(HttpRequest.BodyPublishers.ofString(json))
            .build();

it fails with the error

Code: Select all

restricted header name: "Referer"

while skipping that line fails with a 403 Forbidden response.

This earlier topic suggests 'Referer' is essential. Comparable code in Python works for me if Referer is specified, but fails if it isn't; GET requests are also working fine from my Java/Groovy code.

Is there anything I'm clearly doing wrong, some other workaround, or should I be giving up on HttpClient for now?

Thanks,

Pete

Hi Pete
you are ahead of us!
We have not been evaluating Java 11 yet.
We will need a bit of time to investigate the issue.

Thanks Jmarie! It looks like it should be possible to set the Referer for the Java 11 HttpClient as of 11.0.2 (according to this). In the meantime if I switch back to using HttpsURLConnection it works fine.
