Thank you very much Peter. I missed the point that HttpCacheContext
was extending HttpClientContext.
Unfortunately, httpClient5 Async (CloseableHttpAsyncClient) is not
sending credentials at first request even with your code (the same as
mine except using HttpCacheContext in place of HttpClientContext).
I will check with Oleg on the way to produce logs.
The issue you are having may be the defect just reported as
HTTPCLIENT-2203. I am looking into it. There is no need for wire logs
anymore, because I have a local reproducer.

Oleg
What is broken is the target host port normalization. When using
explicitly defined ports the preemptive authentication works just fine.
Please note the request URI contains a port in it.
This example works just fine for me:
----
public class AsyncPreemptiveBasicClientAuthentication {
public static void main(final String[] args) throws Exception {
final BasicCredentialsProvider credsProvider = new
BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope("httpbin.org", 80),
new UsernamePasswordCredentials("user",
"passwd".toCharArray()));
final CloseableHttpAsyncClient httpclient =
HttpAsyncClients.custom()
.setDefaultCredentialsProvider(credsProvider)
.build();
httpclient.start();
// Generate Basic scheme object and add it to the local auth cache
final BasicScheme basicAuth = new BasicScheme();
basicAuth.initPreemptive(new
UsernamePasswordCredentials("user", "passwd".toCharArray()));
final HttpHost target = new HttpHost("http", "httpbin.org", 80);
// Add AuthCache to the execution context
final HttpClientContext localContext = HttpClientContext.create();
localContext.resetAuthExchange(target, basicAuth);
final SimpleHttpRequest request =
SimpleRequestBuilder.get("http://httpbin.org:80/basic-auth/user/passwd";)
.build();
System.out.println("Executing request " + request);
for (int i = 0; i < 3; i++) {
final Future<SimpleHttpResponse> future = httpclient.execute(
SimpleRequestProducer.create(request),
SimpleResponseConsumer.create(),
localContext,
new FutureCallback<SimpleHttpResponse>() {
@Override
public void completed(final SimpleHttpResponse
response) {
System.out.println(request + "->" + new
StatusLine(response));
System.out.println(response.getBody());
}
@Override
public void failed(final Exception ex) {
System.out.println(request + "->" + ex);
}
@Override
public void cancelled() {
System.out.println(request + " cancelled");
}
});
future.get();
}
System.out.println("Shutting down");
httpclient.close(CloseMode.GRACEFUL);
}
}

Betreff: Re: Preemptive authentication in Http Client 5 Async
Hi Peter,
Thank you for your answer. Once you get an HttpCacheContext instance,
how do you link it with the request ? I see no setter on the
HttpClient nor on the RequestConfig.
Regards,
Christophe

Hi,
I use the HttpCacheContext but I think with the httpclient5 the
preemtive authentication is implemented the same way.

authCache.put(targetHost, basicAuth);
} else if (this.getAuthScheme() == AuthScheme.DIGEST) {

Betreff: Preemptive authentication in Http Client 5 Async
Hi,
I am trying to make preemptive authentication in HttpClient 5 Async
mode using the following code, but I does not work, first request is
still without authentication and the authentication is done on the
second request :
HttpClientContext httpContext = HttpClientContext.create();
CredentialsProvider credentialsProvider = getCredentialsProvider();
if (preemptive) {
URI uri = URI.create(url);
HttpHost targetHost = new HttpHost(uri.getScheme(),
uri.getHost(), uri.getPort());
AuthCache authCache = new BasicAuthCache();
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
httpContext.setAuthCache(authCache);
}
httpContext.setCredentialsProvider(credentialsProvider);
This code was working in httpClient 4. Any suggestion on how to make
preemptive authentication work in HttpClient5 Async ?
Thank you,
Christophe
