Content-Disposition Header does not display Unicode characters properly

[Kuzhali Velmurugan]

Hello,

I am making a RestAssured "GET" API call and asserting the fileName present in "Content-Disposition" header. The fileName contains unicode characters(Different language character set - Eg: Chinese, Hindi).

Rest Assured returns it as URL encoded form of '?'(Content-Disposition=inline; filename="??????????"; filename*=utf-8''%3F%3F%3F%3F%3F%3F%3F%3F%3F%3F)

And browser returns it as:  Content-Disposition: inline; filename="\?\?\?\?\?\?\?\?\?\?"; filename*=utf-8''%E0%B0%AE%E0%B0%BE%E0%B0%9F%E0%B1%8D%E0%B0%B2%E0%B0%BE%E0%B0%A1%E0%B0%82%E0%B0%A1%E0%B0%BF

I would like to get it in the way that Browser returns.

How to do this in RestAssured?

How do you specify your request?

My request is as follows:

given().filter(withUser(owner))
        .param(CONTENT_ID, contentId)
        .get("/getAPI").then().log().ifValidationFails()
        .assertThat().statusCode(200)
        .header("Content-Disposition", containsString((URLEncoder.encode(file.getName()))));

Hmmm. Does the server specify a charset with the response? If not, the default charset of your system is presumed. You can change by using the DecoderConfig.

[Kuzhali Velmurugan]

It is UTF-8 by default. I tried specifying it with Decoder Config too. But didn't help either. RestAssured seems to encode the "??????????" present in "filename"  and returns it in filename* as %3F%3F%3F%3F%3F%3F%3F%3F%3F%3F

[Johan Haleby]

It just came to mind that headers are not part of the content (obviously) so decoder config won't make any difference. And I think that only ascii is allowed in headers, see for example here.

[Kuzhali Velmurugan]

Ok, Thank you. Is it possible to extract raw header value?

[Johan Haleby]

Hmmm as far as I can remember REST Assured just returns what's given to it by Apache HTTP Client. So if Apache HTTP Client supports it RA does (or can) support it as well.
