Craig Flockhart commented on CAMEL-4693:
----------------------------------------
My solution was a little convoluted so maybe there's a better way.
1. Create a Spring factory for HttpContexts e.g. (in Scala):
{code}
@Component
class HttpContextFactory {
@Value("${http.host}")
private var httpHost = "localhost"
@Value("${http.port}")
private var httpPort = 9001
val httpContext = new BasicHttpContext
private val authCache = new BasicAuthCache
private val basicAuth = new BasicScheme
@PostConstruct
def afterInject() = {
val targetHost = new HttpHost(httpHost, httpPort)
authCache.put(targetHost, basicAuth)
httpContext.setAttribute(ClientContext.AUTH_CACHE, authCache)
}
}
{code}
2. Declare an HttpContext in the Spring application context file:
{code}
<bean id="myHttpContext" factory-bean="httpContextFactory"
factory-method="httpContext"/>
{code}
3. Reference the context in the http4 URL:
...&httpContext=myHttpContext
> http4 Component not exposing HttpContext

> Project: Camel
> Issue Type: Improvement
> Components: camel-http
> Affects Versions: 2.8.2
> Reporter: Jeff Segal
> Assignee: Claus Ibsen
> Fix For: 2.9.2, 2.10.0

> Attachments: http4-httpContext.patch

>
> HttpComponents 4.x provides a facility to use a HttpContext for a given
> request by calling HttpClient.execute(HttpUriRequest, HttpContext), but it
> looks like the http4 Camel Component doesn't have hooks to use this. Looking
> at the latest source of org.apache.camel.component.http4.HttpProducer, I only
> see one way of calling HttpClient.execute():
> protected HttpResponse executeMethod(HttpUriRequest httpRequest) throws
> IOException {
> return httpClient.execute(httpRequest);
> }
> Perhaps this could be made available in a similar fashion to
> HttpClientConfigurer? (for example creating a HttpContextConfigurer)
> My particular symptom is that I'm unable to force the http4 component to use
> preemptive authentication, which relies on HttpContext in HttpClient 4.x. In
> HttpClient 3.x, this was made possible by the HttpClientParams flag
> "authenticationPreemptive". However, it appears that this was removed for 4.x
> in favor of using HttpContext because of security concerns.
