Apache CXF - Set HTTP header - apache

Question

I have to set some http header fields in a Apache CXF client:
I tried it via Interceptor:
public class HttpHeaderInterceptor extends AbstractPhaseInterceptor<Message> {
private String userId;
private String xAuthorizeRoles;
private String host;
public HttpHeaderInterceptor() {
super(Phase.POST_PROTOCOL);
}
#Override
public void handleMessage(Message message) throws Fault {
Map<String, List> headers = (Map<String, List>) message.get(Message.PROTOCOL_HEADERS);
try {
System.out.println("HttpHeaderInterceptor Host: " + host + " UserId: " + userId + " X-AUTHORIZE-roles: " + xAuthorizeRoles);
headers.put("Host", Collections.singletonList(host));
headers.put("UserId", Collections.singletonList(userId));
headers.put("X-AUTHORIZE-roles", Collections.singletonList(xAuthorizeRoles));
} catch (Exception ce) {
throw new Fault(ce);
}
}
public void setUserId(String userId) {
this.userId = userId;
}
public void setxAuthorizeRoles(String xAuthorizeRoles) {
this.xAuthorizeRoles = xAuthorizeRoles;
}
public void setHost(String host) {
this.host = host;
}
}
in my dynamic client class the methode:
public void setHttHeaderInterceptor(String userId, String xAuthorizeRoles){
Client cxfClient = ClientProxy.getClient(this.abgWebServicePort);
HttpHeaderInterceptor httpHeaderInterceptor = new HttpHeaderInterceptor();
httpHeaderInterceptor.setHost("example.org");
httpHeaderInterceptor.setUserId(userId);
httpHeaderInterceptor.setxAuthorizeRoles(xAuthorizeRoles);
cxfClient.getOutInterceptors().add(httpHeaderInterceptor);
}
is called before I invoke the remote service:
For each call the userId and the xAuthorizeRoles should vary but when I inspect by calls via tcpdump all calls have the same values in the header fields.
Any ideas?

I Have solved my problem:
adding the interceptor via xml configuration:
<jaxws:client id="clientBean" serviceClass="org.example.service.ServicePortType"
address="example.org/src/service/ServicePort">
<jaxws:outInterceptors>
<bean class="org.example.interceptor.HttpHeaderInterceptor"/>
</jaxws:outInterceptors>
<jaxws:properties>
<entry key="mtom-enabled" value="true"/>
</jaxws:properties>
</jaxws:client>
in the client class I altered setHttpHeaderInterceptor to
public void setHttpHeaderInterceptor(String userId, String xAuthorizeRoles){
Client cxfClient = ClientProxy.getClient(this.servicePort);
cxfClient.getRequestContext().put("HTTP_HEADER_HOST", "example.org");
cxfClient.getRequestContext().put("HTTP_HEADER_USER_ID", userId);
cxfClient.getRequestContext().put("HTTP_HEADER_X_AUTHORIZE-ROLES", xAuthorizeRoles);
}
the interceptor class
#Override
public void handleMessage(Message message) throws Fault {
Map<String, List> headers = (Map<String, List>) message.get(Message.PROTOCOL_HEADERS);
try {
headers.put("Host", Collections.singletonList(message.get("HTTP_HEADER_HOST")));
headers.put("KD_NR", Collections.singletonList(message.get("HTTP_HEADER_KD_NR")));
headers.put("X-AUTHORIZE-roles", Collections.singletonList(message.get("HTTP_HEADER_X_AUTHORIZE-ROLES")));
} catch (Exception ce) {
throw new Fault(ce);
}
}
and now it work's.
With this approach I can set HTTP-Header fields at runtime.

You should have used :Phase.POST_LOGICAL instead of Phase.POST. This worked for me

Here is a code snippet to copy a custom HTTP header (from the request) on the response in a single CXF out interceptor.
public void handleMessage(SoapMessage message) throws Fault {
// Get request HTTP headers
Map<String, List<String>> inHeaders = (Map<String, List<String>>) message.getExchange().getInMessage().get(Message.PROTOCOL_HEADERS);
// Get response HTTP headers
Map<String, List<String>> outHeaders = (Map<String, List<String>>) message.get(Message.PROTOCOL_HEADERS);
if (outHeaders == null) {
outHeaders = new HashMap<>();
message.put(Message.PROTOCOL_HEADERS, outHeaders);
}
// Copy Custom HTTP header on the response
outHeaders.put("myCustomHTTPHeader", inHeaders.get("myCustomHTTPHeader"));
}

If required to set standard HTTP header then it can be done using http conduit also.
<http-conf:conduit
name="*.http-conduit">
<http-conf:client AllowChunking="false" AcceptEncoding="gzip,deflate" Connection="Keep-Alive"
Host="myhost.com"/>
</http-conf:conduit>
