I have web service implemented in Apache CXF. Is there way how can I set SOAP header to request (server side) using AddressingProperties?
This works for me:
List<Header> headers = new ArrayList<Header>();
Header messageIDHeader = new Header(new QName("http://www.w3.org/2005/08/addressing", "MessageID", "wsa"), some_messageID, new JAXBDataBinding(String.class));
headers.add(messageIDHeader);
Header relatesToHeader = new Header(new QName("http://www.w3.org/2005/08/addressing", "RelatesTo", "wsa"), some_relatesTo_ID, new JAXBDataBinding(String.class));
headers.add(relatesToHeader);
wsContext.getMessageContext().put(Header.HEADER_LIST, headers);
But I would like to use org.apache.cxf.ws.addressing.AddressingProperties - something like this:
RelatesToType soapRelatesTo = new RelatesToType();
soapRelatesTo.setValue(some_relatesTo_ID);
soapAddressingHeaders.setRelatesTo(soapRelatesTo);
AttributedURIType soapMsgId = new AttributedURIType();
soapMsgId.setValue(some_messageID);
soapAddressingHeaders.setMessageID(soapMsgId);
How can I pass that to request? I am not able to set it through MessageContext
Adding soapAddressingHeaders to MessageContext
messageContext.put("http://www.w3.org/2005/08/addressing", soapAddressingHeaders);
works correctly but I forgot to enable WS-A addressing for CXF:
<jaxws:features>
<wsa:addressing xmlns:wsa="http://cxf.apache.org/ws/addressing"/>
</jaxws:features>

I'm trying to create an httpclient in Blazor Server side which would create the least amount of configuration effort every time I call my webapi.
Essentially I would like achieve the following:
Named HTTPClient I can automatically call when I call a function in my webapi.
The webapi requires a bearer token, which I get by calling AcquireTokenSilent
Would be great if I don't have to specify the httpclient when I call the api
The webapi has been added as a service reference, so there is scaffold classes created under the namespace myapp.server.api
To start this off, I created the following in startup:
services.AddHttpClient<myapp.server.api.swaggerClient>(c =>
{
c.BaseAddress = new Uri("https://api.myapp.com/");
AzureADB2COptions opt = new AzureADB2COptions();
Configuration.Bind("AzureAdB2C", opt);
IConfidentialClientApplication cca =
ConfidentialClientApplicationBuilder.Create(opt.ClientId)
.WithRedirectUri(opt.RedirectUri)
.WithClientSecret(opt.ClientSecret)
.WithB2CAuthority(opt.Authority)
.WithClientName("myWebapp")
.WithClientVersion("0.0.0.1")
.Build();
IHttpContextAccessor pp;
string signedInUserID = context.User.FindFirst(ClaimTypes.NameIdentifier).Value;
new MSALStaticCache(signedInUserID, pp.HttpContext).EnablePersistence(cca.UserTokenCache);
var accounts = cca.GetAccountsAsync().Result;
AuthenticationResult result = null;
result = cca.AcquireTokenSilent(opt.ApiScopes.Split(' '), accounts.FirstOrDefault()).ExecuteAsync().Result;
c.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", result.AccessToken);
});
My hope is to be able to call my api in my views in this way:
myapp.server.api.swaggerClient t = new myapp.server.api.swaggerClient();
currentCount = t.WeatherForecastAsync().Result.FirstOrDefault().Summary;
calling a new instance of swaggerclient requires me to specify an httpclient, so my hopes is to inject the httpclient I am configuring on a global level for that type can be injected automatically.
The pieces I need help with:
Given that I have specified my httpclient scoped to a specific type, would it call automatically if I call a function in my webapi? (Does not seem to fire when debugging)
To get the bearer token, I need to get the current userID, which is in the authstateprovider... seeing that this is in Startup, is getting it from DI even possible?
Any easy way to inject the httpclient on the constructor of my webapi classes? would I be able to get the httpclient in the constructor so that I essentially have a parameterless constructor not asking for httpclient?
Concerning your first question, inject the Web API HttpClient like this in your view:
#inject myapp.server.api.swaggerClient MyClient
and then in the code block:
currentCount = MyClient.WeatherForecastAsync().Result.FirstOrDefault().Summary;
You should be able to debug the code inside AddHttpClient.
I am using Restlet on Google App Engine for developing my sample application.
The front end is Angular 2 App.
The Rest API is working fine with browser.
However, I am getting the following issue when I am trying to hit the URL from Angular app.
XMLHttpRequest cannot load https://1-dot-jda-saas-training-02.appspot.com/rest/projectsBillingInfo/123. The 'Access-Control-Allow-Origin' header contains multiple values 'http://evil.com/, *', but only one is allowed. Origin 'http://localhost:3000' is therefore not allowed access.
So, I thought I will go ahead and add the CORS headers in the response. I used CorsFilter for that as follows but the issue is still there. When I see the header of the Response, I do not see any CORS headers. What am I missing here?
#Override
public Restlet createInboundRoot() {
// Create a router Restlet that routes each call to a
// new instance of HelloWorldResource.
Router router = new Router(getContext());
CorsFilter corsFilter = new CorsFilter(getContext(), router);
corsFilter.setAllowedOrigins(new HashSet<String>(Arrays.asList("*")));
corsFilter.setAllowedCredentials(true);
// Defines only one route
router.attachDefault(AddressServerResource.class);
router.attach("/contact/123",ContactServerResource.class);
router.attach("/projectsBillingInfo/123",ProjectBillingResource.class);
return corsFilter;
}
EDIT
I could get this working. May be I was doing some mistake.
But, I am not able to make this work with the GaeAuthenticator. When I am putting the GaeAuthenticator along with Corsfilter, it skips the authentication part of it. So, either the authentication works or the corsfilter works but not both. Is there any easy way to set/modify HTTP headers in restlet.
Here is the code I am using ..
#Override
public Restlet createInboundRoot() {
// Create a router Restlet that routes each call to a
// new instance of HelloWorldResource.
Router router = new Router(getContext());
// Defines only one route
router.attachDefault(AddressServerResource.class);
router.attach("/contact/123",ContactServerResource.class);
router.attach("/projectsBillingInfo/123",ProjectBillingResource.class);
GaeAuthenticator guard = new GaeAuthenticator(getContext());
guard.setNext(router);
CorsFilter corsFilter = new CorsFilter(getContext(), router);
corsFilter.setAllowedOrigins(new HashSet<String>(Arrays.asList("*")));
corsFilter.setAllowedCredentials(true);
return corsFilter;
First, I think you can use the service instead of the filter:
public MyApplication() {
CorsService corsService = new CorsService();
corsService.setAllowedCredentials(true);
corsService.setSkippingResourceForCorsOptions(true);
getServices().add(corsService);
}
Do you mind to set the "skippingServerResourceForOptions"?
#Override
public Restlet createInboundRoot() {
// Create a router Restlet that routes each call to a
// new instance of HelloWorldResource.
Router router = new Router(getContext());
// Defines only one route
router.attachDefault(AddressServerResource.class);
router.attach("/contact/123",ContactServerResource.class);
router.attach("/projectsBillingInfo/123",ProjectBillingResource.class);
return router;
}

Following is my App Engine Endpoint. I annotate it as ApiMethod.HttpMethod.GET because I want to be able to make a get call through the browser. The class itself has a few dozen methods understandably. Some of them using POST. But getItems is annotated with GET. When I try to call the url through a browser, I get a 405 error
Error: HTTP method GET is not supported by this URL
The code:
#Api(name = "myserver",
namespace = #ApiNamespace(ownerDomain = "thecompany.com", ownerName = "thecompany", packagePath = ""),
version = "1", description = "thecompany myserver", defaultVersion = AnnotationBoolean.TRUE
)
public class myserver {
#ApiMethod(name = "getItems", httpMethod = ApiMethod.HttpMethod.GET)
public CollectionResponse<Item> getItems(#Named("paramId") Long paramId) {
…
return CollectionResponse.<Item>builder().setItems(ItemList).build();
}
}
This is not for localhost, it’s for the real server. Perhaps I am forming the url incorrectly. I have tried a few urls such as
https://thecompanymyserver.appspot.com/_ah/spi/com.thecompany.myserver.endpoint.myserver.getItems/v1/paramId=542246400
https://thecompanymyserver.appspot.com/_ah/spi/myserver/NewsForVideo/v1/542246400
The proper path for this is /_ah/api/myserver/1/getItems. /_ah/spi refers to the backend path, which only takes POST requests of a different format.
Side note: API versions are typical "vX" instead of just "X".
You can use the api explorer to find out whether you're using the correct url. Go to
https://yourprojectid.appspot.com/_ah/api/explorer
this works on the devserver as well:
http://localhost:8080/_ah/api/explorer
Also if you're not planning to use the google javascript api client you should add path="..." to your #ApiMethods, so you are sure about what the path actually is.
I´m using CXF to consume a WebService and, as the responses are quite large, I´m requesting with a gzip "Accept-Encoding" and using GZIPInInterceptor to handle the gziped response. Also my WSDL is very large (360kb) and it takes a long time(+10 seconds) to create the stub, because it has to read and parse the WSDL, so I´m creating the stub once and reusing it.
The problem is, whenever I try to use two different methods the second request gives me an error saying it is expecting the previous request.
To illustrate my problem I created a simple example with this public WebService:
http://www.webservicex.net/BibleWebservice.asmx?WSDL
Without the GZip compression it works fine:
BibleWebserviceSoap bibleService = new BibleWebservice().getBibleWebserviceSoap();
String title = bibleService.getBookTitles();
response.getWriter().write(title);
String johnResponse = bibleService.getBibleWordsbyKeyWord("John");
response.getWriter().write(johnResponse);
I´m able to receive both responses.
Enabling Gzip compression:
BibleWebserviceSoap bibleService = new BibleWebservice().getBibleWebserviceSoap();
//GZIP compression on bibleService
Client client = ClientProxy.getClient(bibleService);
client.getInInterceptors().add(new GZIPInInterceptor());
client.getInFaultInterceptors().add(new GZIPInInterceptor());
// Creating HTTP headers
Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Accept-Encoding", Arrays.asList("gzip"));
// Add HTTP headers to the web service request
client.getRequestContext().put(Message.PROTOCOL_HEADERS, headers);
String title = bibleService.getBookTitles();
response.getWriter().write(title);
String johnResponse = bibleService.getBibleWordsbyKeyWord("John");
response.getWriter().write(johnResponse);
When I try to receive the second response I´m getting this exception:
org.apache.cxf.interceptor.Fault: Unexpected wrapper element {http://www.webserviceX.NET}GetBookTitlesResponse found. Expected {http://www.webserviceX.NET}GetBibleWordsbyKeyWordResponse.
On my real application I´m getting an exception with the request:
org.apache.cxf.binding.soap.SoapFault: OperationFormatter encountered an invalid Message body. Expected to find node type 'Element' with name 'GetAvailabilityRequest' and namespace 'http://schemas.navitaire.com/WebServices/ServiceContracts/BookingService'. Found node type 'Element' with name 'ns4:PriceItineraryRequest' and namespace 'http://schemas.navitaire.com/WebServices/ServiceContracts/BookingService'

Thank you
Instead of setting the protocol headers directly like that, use CXF's GZIPOutInterceptor to handle that.
Either that or reset the PROTOCOL headers for each request. When set like that, the headers map gets updated as the request goes through the chain. In this case, the soapaction gets set. This then gets resent on the second request.
I'm trying to get custom response message header in Silverlight application.
on server-side new MessageHeader added to response headers:
OperationContext.Current.OutgoingMessageHeaders.Add(MessageHeader.CreateHeader("headerName", "headerNS", "The header value"));
and I can see this header in Fiddler:
s:Envelope [
xmlns:s=http://schemas.xmlsoap.org/soap/envelope/
]
s:Header
headerName [ xmlns=headerNS ] The
header value
But, I can't find a way to read header value in Silverlight application service callback:
using (new OperationContextScope(proxy.InnerChannel))
{
var headers = OperationContext.Current.IncomingMessageHeaders;
// headers is null :(
}
Does anyone encountered with similar issue?
Getting SOAP headers in responses on Silverlight isn't as easy as it should be. If you use the event-based callbacks, you're out of luck - it just doesn't work. You need to use the Begin/End-style operation call, like in the example below.
void Button_Click(...)
{
MyClient client = new MyClient();
IClient proxy = (IClient)client; // need to cast to the [ServiceContract] interface
proxy.BeginOperation("hello", delegate(IAsyncResult asyncResult)
{
using (new OperationContextScope(client.InnerChannel))
{
proxy.EndOperation(asyncResult);
var headers = OperationContext.Current.IncomingMessageHeaders;
// now you can access it.
}
});
}
Notice that you cannot use the generated client (from slsvcutil / add service reference) directly, you need to cast it to the interface, since the Begin/End methods are not exposed (explicitly implemented) on the client class.
To get headers from http request try to use Client HTTP stack.
The easies way to do it is to register the prefix, for example:
WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);
