Considering the test07 stream is already created the following code snippet won't get response body in the exception stack trace.
try {
URI dataFlowUri = URI.create("http://localhost:9393");
DataFlowOperations dataFlowOperations = new DataFlowTemplate(dataFlowUri);
StreamDefinition streamDefinition = Stream.builder(dataFlowOperations)
.name("test07")
.definition("time|log")
.create();
}
catch (Exception ex){
ex.printStackTrace();
}

on other hand when Post request this directly
http://localhost:9393/streams/definitions?name=test07&definition=time%20%7C%20log&description=test07
the response as follow with status code 409
[
{
"logref": "DuplicateStreamDefinitionException",
"message": "Cannot create stream test07 because another one has already been created with the same name"
}
]
I want to get response body when exception occur
so anyone can help if I'm missing something here?
I had to override the default rest template to get the response body as desired.
ClientHttpRequestFactory factory = new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory());
RestTemplate restTemplate = new RestTemplate(factory);
URI dataFlowUri = URI.create("http://localhost:9393");
DataFlowOperations dataFlowOperations = new DataFlowTemplate(dataFlowUri, restTemplate);
StreamDefinition streamDefinition = Stream.builder(dataFlowOperations)
.name("test07")
.definition("time|log")
.create();
thanks
This service receives the multipart request from mobile client and passes on the request to downstream service for uploading the image. I am seeing 415 Unsupported Media Type in my downstream service
private void makeRequest(HttpRequest<Buffer> httpRequest,
Promise<Object> future,
RequestContext requestContext,
RoutingContext routingContext,
Entry entry) {
MultipartForm multipartForm = MultipartForm.create();
MultiMap attributes = routingContext.request()
.formAttributes();
attributes.forEach(attribute -> {
multipartForm.attribute(attribute.getKey(), attribute.getValue());
});
routingContext.fileUploads()
.forEach(fileUpload -> {
multipartForm.binaryFileUpload(fileUpload.name(), fileUpload.fileName(),
fileUpload.uploadedFileName(), fileUpload.contentType());
});
httpRequest.sendMultipartForm(multipartForm, response -> {
handleResponse(routingContext, future, response, requestContext, entry);
});
}
Getting the below exception

API signature of my downstream service

Can someone please guide what is wrong in my code snippet or is there any setting which needs to be enabled in vertx server or vertx web client?
Thanks,

I was able to resolve this by explicitly setting the header
.putHeader("content-type", "multipart/form-data")
I have an apache camel application that requires sending log files to an endpoint and this requires Basic Authentication. I was able to pass the authMethod, authusername and authPassword to the url as specified in the camel documentation but the challange I'm having is that I keep getting null response from the endpoint after starting the application.
However, the same endpoint returns response code and response body using postman.
Below is my code:
from("{{routes.feeds.working.directory}}?idempotent=true")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
String fileName = exchange.getIn().getHeader(Exchange.FILE_NAME, String.class);
File file = exchange.getIn().getBody(File.class);
multipartEntityBuilder.addPart("file",
new FileBody(file, ContentType.MULTIPART_FORM_DATA, fileName));
exchange.getOut().setBody(multipartEntityBuilder.build());
Message out = exchange.getOut();
int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);
log.info("response code "+responseCode);
}
})
.setHeader(Exchange.HTTP_QUERY,
constant("authMethod=Basic&authUsername="+username+"&authPassword="+password+""))
.to(TARGET_WITH_AUTH +"/"+uuid+"/files")
.log(LoggingLevel.DEBUG, "response code >>>>"+Exchange.HTTP_RESPONSE_CODE)
.log(LoggingLevel.INFO, "RESPONSE BODY ${body}")
.end();
Kindly help review and advise further
For HTTP basic authentication I use this before sending a request
<setHeader headerName="Authorization">
<constant>Basic cm9vdDpyb290</constant>
</setHeader>
cm9vdDpyb290 - Encoded Base64 root:root(username and password) string
This was fixed by using httpClient to send my requests with Basic Authentication. Apparently, authMethod in apache camel doesn't send the credentials along with the Post Request and that's why I was getting the initial 401 response code.
Thank y'all for your contributions.
I have a RESTful server created with ASP.Net and am trying to connect to it with the use of a RESTful client from Unity. GET works perfectly, however I am getting a validation error when sending a POST request. At the same time both GET and POST work when sending requests from Postman.
My Server:
[HttpPost]
public IActionResult Create(User user){
Console.WriteLine("***POST***");
Console.WriteLine(user.Id+", "+user.sex+", "+user.age);
if(!ModelState.IsValid)
return BadRequest(ModelState);
_context.Users.Add(user);
_context.SaveChanges();
return CreatedAtRoute("GetUser", new { id = user.Id }, user);
}
My client:
IEnumerator PostRequest(string uri, User user){
string u = JsonUtility.ToJson(user);
Debug.Log(u);
using (UnityWebRequest webRequest = UnityWebRequest.Post(uri, u)){
webRequest.SetRequestHeader("Content-Type","application/json");
yield return webRequest.SendWebRequest();
string[] pages = uri.Split('/');
int page = pages.Length - 1;
if (webRequest.isNetworkError || webRequest.isHttpError){
Debug.Log(pages[page] + ":\nReceived: " + webRequest.downloadHandler.text);
}
else{
Debug.Log(pages[page] + ":\nReceived: " + webRequest.downloadHandler.text);
}
}
}
I was trying both with the Json conversion and writing the string on my own, also with the WWWForm, but the error stays.
The error says that it's an unknown HTTP error. When printing the returned text it says:
"One or more validation errors occurred.","status":400,"traceId":"|b95d39b7-4b773429a8f72b3c.","errors":{"$":["'%' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0."]}}
On the server side it recognizes the correct method and controller, however, it doesn't even get to the first line of the method (Console.WriteLine). Then it says: "Executing ObjectResult, writing value of type 'Microsoft.AspNetCore.Mvc.ValidationProblemDetails'".
Here're all of the server side messages:
info: Microsoft.AspNetCore.Hosting.Diagnostics[1]
Request starting HTTP/1.1 POST http://localhost:5001/user application/json 53

I have no idea what is happening and how to solve it. Any help will be strongly appreciated!
Turned out I was just missing an upload handler. Adding this line solved it: webRequest.uploadHandler = new UploadHandlerRaw(System.Text.Encoding.UTF8.GetBytes(JsonObject));
Integration Tests (production code works well) fail while requesting REST endpoints secured with #RolesAllowed.
Following error is thrown:
[5/20/19 8:44:21:363 CEST] 00000109 com.ibm.ws.security.jaspi.JaspiServiceImpl I CWWKS1652A: Authentication failed with status AuthStatus.SEND_FAILUR for the web request
/banking/users/bed6109f-ef8a-47ec-8fa4-e57c71415a10. The user defined Java Authentication SPI for Containers (JASPIC) service null has determined that the authentication data is not valid.
Project is based on OpenLiberty with JWT. The difference is in the UI part. My UI is based on Angular, so for authentication (JWT issuing) following REST Endpoint is used:
#RequestScoped
#Path("/tokens")
#PermitAll
public class AuthResource {
#Inject
private SecurityContext securityContext;
#Inject
private AuthService authService;
#GET
#Produces(MediaType.APPLICATION_JSON)
public Response getJwt() {
if (securityContext.isCallerInRole("USER") || securityContext.isCallerInRole("ADMIN")) {
String name = securityContext.getCallerPrincipal().getName();
AuthPojo authPojo = authService.createJwt(name);
return Response.ok(authPojo).build();
}
return Response.status(Response.Status.UNAUTHORIZED).build();
}
}
So:
UI (Angular) calls https://localhost:5051/tokens with Header "Authorization: Basic ENCODED_USERNAME_PASSWORD"
Backend responds with newly generated JWT Token in body and Header "Set-Cookie: LtpaToken2=SOME_TOKEN; Path=/; HttpOnly"
UI uses this token for all other requests against REST Endpoints annotated with "#RolesAllowed({"ADMIN", "USER" })"
Once again, in production code, all this schema works well, but Integration Tests fail.
Here is Integration Test code:
public class MyResourceIT {
private static final String URL = "https://localhost:" +
System.getProperty("liberty.test.ssl.port") + "/users/" + USER_ID1;
private String authHeader;
#Before
public void setup() throws Exception {
authHeader = "Bearer " + new JwtVerifier().createAdminJwt(USER_NAME1);
}
#Test
public void getUserAndAccounts() {
Response response = HttpClientHelper.processRequest(URL, "GET", null, authHeader);
System.out.println("My URL: " + URL);
System.out.println("My Header: " + authHeader);
assertThat("HTTP GET failed", response.getStatus(), is(Response.Status.OK.getStatusCode()));
}
}
Looks like the problem why 401 instead 200 is returned is LtpaToken2 Cookie which is not set in Test. Instead Header "Authorization: Bearer JWT_TOKEN" is used, but this doesn't work.
I Expect that Endpoint secured with "#RolesAllowed" should respond with 200 when header "Authorization: Bearer JWT_TOKEN" is provided. Are there some tricks that should be done with a cookie?
UPDATE 2019-05-23
This is the whole project.
Example test is located here. The failing test is ignored
#Test
public void getUserAndAccounts_withJwt_authorized() throws IOException {
Response response = HttpClientHelper.processRequest(URL, "GET", null, authHeader, null);
assertThat(response.getStatus(), is(Response.Status.OK.getStatusCode()));
}
JWT token is created within following class in the #Before annotated method:
private String authHeader;
#Before
public void setup() throws Exception {
authHeader = "Bearer " + new JwtVerifier().createAdminJwt(USER_NAME1);
}
One thing to notice, that project is based on the following project.
Since the CWWKS1652A message was issued without a provider name, this indicates that appSecurity-3.0 is set and that at least a JSR-375 (a.k.a. Java EE Security API Specification) HttpAuthenticationMechanism is configured for the application, either via annotation or bean implementation. This causes an internal JASPIC provider to be created, therefore the null in the CWWKS1652A message, and this provider invokes the configured HttpAuthenticationMechanism that returns a AuthStatus.SEND_FAILURE status.
Please ensure that you intend to use an HttpAuthenticationMechanism and that valid authentication credentials are passed when challenged by this mechanism.
If it is determined that there is no HttpAuthenticationMechanism configured, then determine if there is an external JASPIC provider factory (AuthConfigFactory implementation) set via the authconfigprovider.factory property. In either case, it is the provider that responds with the AuthStatus.SEND_FAILURE seen in the message.
