-------------------------------------------
Hi [~ctabin]
I ran a test with {{HttpClient 5.4}} and was able to observe the
{{Content-Type}} header being returned correctly in the response, as
demonstrated by the following example:
{code:java}
Accept-Ranges: bytes
Age: 61964
Cache-Control: max-age=604800
Content-Type: text/html; charset=UTF-8
Date: Fri, 20 Sep 2024 11:54:59 GMT
Etag: "3147526947"
Expires: Fri, 27 Sep 2024 11:54:59 GMT
Last-Modified: Thu, 17 Oct 2019 07:18:26 GMT
Server: ECAcc (dcd/7D24)
Vary: Accept-Encoding
X-Cache: HIT
{code}
{code:java}
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
final HttpGet request = new HttpGet("https://example.com";);
try (CloseableHttpResponse response = httpClient.execute(request)) {
for (final Header header : response.getHeaders()) {
System.out.println(header.getName() + ": " + header.getValue());
}
final Header contentType = response.getFirstHeader("Content-Type");
if (contentType != null) {
System.out.println("Content-Type found: " +
contentType.getValue());
} else {
System.out.println("Content-Type header is missing!");
}
}
}
}{code}
> Regression: Content-Type header not returned anymore
> ----------------------------------------------------
>
> Key: HTTPCLIENT-2342
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2342
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 5.4-beta1
> Reporter: Cedric Tabin
> Priority: Major
>
> Hello,
> We just upgraded today to httpclient5 version 5.4. It seems that the header
> `Content-Type` is not returned anymore by the API, even when listing all the
> headers.
> {code:java}
> client.execute(httpRequest, r -> {
> //does not print Content-Type header
> for(Header h : r.getHeaders()) {
> System.out.println("## "+h.getName()+": "+h.getValue());
> }
> System.out.flush();
> return null;
> });
> {code}
> We can ensure that the `Content-Type` header is well set by the server by
> browsing to the same URL and inspecting the network.
> Our code didn't change and with the version 5.3.1, the Content-Type is
> correctly received.
