How can I use the Firebase java client from within a jax-rs service?
Let's say I make a the following call? That's an async callback?
authClient.checkAuthStatus(new SimpleLoginAuthenticatedHandler() {
#Override
public void authenticated(FirebaseSimpleLoginError error, FirebaseSimpleLoginUser user) {
if (error != null) {
result = "{\"result\" : \"Error checking authentication\"}";
} else if (user == null) {
result = "{\"result\" : \"Not logged in\"}";
} else {
deferred.resolve("done");
}
}
});
The jax-rs resource is returned before the completion of that async method. Is there any way to make this work?

#Route(...)
public Uni<?> call() {
return Uni.createFrom().voidItem();
}
throws a NullPointerException: Invalid value returned by Uni: null
However
#Route(...)
public Uni<Void> call() {
return Uni.createFrom().voidItem();
}
works perfectly fine and responds with HTTP 204
How do I manage to get either Uni<Void> or Uni<AnyObject> from the same method?
I need to return http 204 only in specific scenarios
You can't do that directly as the types are different.
I would recommend using RESTEasy Reactive and do:
#GET
public Uni<Response> call() {
Uni<AnyObject> uni = .... ;
return uni
.onItem().transform(res -> {
if (res == null) return Response.noContent().build();
return Response.ok(res).build();
});
}
By emitting a Response object, you can customize the response status.
Another solution if you want to keep using Reactive Routes is to not return a Uni, but get the RoutingContext as a parameter:
#Route(...)
public void call(RoutingContext rc) {
HttpServerResponse response = rc.response();
Uni<AnyObject> uni = .... ;
return uni
.subscribe().with(res -> {
if (res == null) response.setStatus(204).end();
else response.setStatus(200).end(res);
}, failure -> rc.fail(failure)); // will produce a 500.
}
In my spring boot app, I want to return different types of response codes with response body.
#RequestMapping(method = RequestMethod.POST, value = "/users")
public ResponseEntity<User> userSignsUp(#RequestBody User user) {
if(userService.getUserByNic(user.getNic()).equals(userService.getUserByNic(user.getNic()))) {
UserErrorBean userError = new UserErrorBean("User already exist","406 error");
return ResponseEntity<>(userError ,HttpStatus.CONFLICT); }
userService.userSave(user);
return ResponseEntity<>(user, HttpStatus.CREATED);
}
This is my rest Controller and I want to return different responses based on different conditions. But it only returns condition if user NIC condition is met. If add user to database, it throws NullPointerException().
I want to return responses according to the request.
You can write a simple RestController like this.
#PostMapping("/users")
public ResponseEntity<User> userSignsUp(#RequestBody User user) {
if(user == null){
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
if(userService.getUserByNic(user.getNic()).equals(userService.getUserByNic(user.getNic()))) {
UserErrorBean userError = new UserErrorBean("User already exist","406 error");
return new ResponseEntity<>(userError, HttpStatus.CONFLICT);
}
if(userService.userSave(user)) { // make it return boolean on success or failed
return new ResponseEntity<>(user, HttpStatus.CREATED);
} else {
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
}
Can someone explain my why that client (Xamarin.Forms PCL) call returns null?
HttpResponseMessage response = await OfflineSyncStoreManager.Instance.MobileAppClient.InvokeApiAsync<HttpResponseMessage>("ResetTruckAuftragWorkflow");
response is null. When I execute that in a console app it returns the
valid http response.
I use the latest stable ZUMO nugets in client and backend. There is my ZUMO backend code:
[Authorize]
[MobileAppController]
public class ResetTruckAuftragWorkflowController : ApiController
{
private readonly RcsMobileContext _rcsMobileContext;
private readonly TruckFahrerInfo _truckFahrerInfo;
public ResetTruckAuftragWorkflowController()
{
_rcsMobileContext = new RcsMobileContext();
_truckFahrerInfo = new TruckFahrerInfo(this.User as ClaimsPrincipal);
}
// POST api/ResetTruckAuftragWorkflow
[HttpPost]
public async Task<IHttpActionResult> PostAsync()
{
if (ModelState.IsValid)
{
using (var transaction = _rcsMobileContext.Database.BeginTransaction())
{
try
{
var truckAuftragList = _rcsMobileContext.TruckAuftrags.PerUserFilter(_truckFahrerInfo.FahrerId);
var truckAppIds = truckAuftragList?.Select(ta => ta.TruckAppId).ToArray();
if (truckAppIds != null)
{
foreach (var truckAppId in truckAppIds)
{
await _rcsMobileContext.Database.ExecuteSqlCommandAsync(_tawQueryTaskStatus10, truckAppId);
await _rcsMobileContext.Database.ExecuteSqlCommandAsync(_tawQueryTaskStatus5, truckAppId);
await _rcsMobileContext.Database.ExecuteSqlCommandAsync(_talQuery, truckAppId);
await _rcsMobileContext.Database.ExecuteSqlCommandAsync(_taQuery, truckAppId);
}
}
await _rcsMobileContext.Database.ExecuteSqlCommandAsync(_taQuery, _truckFahrerInfo.FahrerId);
transaction.Commit();
}
catch (Exception e)
{
transaction.Rollback();
return BadRequest($"Transaction failed: {e}");
}
}
return Ok();
}
else
{
return BadRequest(ModelState);
}
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
_rcsMobileContext.Dispose();
}
base.Dispose(disposing);
}
}

InvokeApiAsync decodes the body that is returned and de-serializes the JSON into type T. You should not use HttpResponseMessage for this purpose as it is not serializable.
If you don't care about the body, use the non-generic form of InvokeApiAsync.
I'm implementing 2fa with IdentityServer3 + Asp.Net Identity (2.2.1). I'm stuck on the 2fa implementation. I've looked at the "AspNetIdentity_2fa" sample, which helped a lot.
I have everything wired up, except for the cookie that indicates the browser has been successfully authenticated. I can set the cookie during the code confirmation, but I cannot get to the cookie in the PostAuthenticateLocalAsync() call to see whether or not to take the 2fa path.
protected override Task<AuthenticateResult> PostAuthenticateLocalAsync(User user, SignInMessage message)
{
if (user.TwoFactorEnabled) // && !TwoFactorCookieSet...
{
return Task.FromResult(new AuthenticateResult("/auth/sendcode", user.Id, user.DisplayName));
}
return base.PostAuthenticateLocalAsync(user, message);
}
I believe I'm taking the correct approach in using the partial logins, but how would I detect that the current browser has already been approved?
More detail: the /auth/sendcode is the standard Asp.Net Identity pages/flow for 2fa, combined with the partial login logic from the sample.
Okay, I found that OwinEnvironmentService can be injected into IdentityServer services. I can get the cookies via OwinEnvironmentService. I'd be interested to hear any opinions on this solution (this isn't meant to be production-ready, it's just a concept):
internal class UserService : AspNetIdentityUserService<User, string>
{
private readonly OwinEnvironmentService _owinEnvironmentService;
public UserService(UserManager userMgr, OwinEnvironmentService owinEnvironmentService) : base(userMgr)
{
_owinEnvironmentService = owinEnvironmentService;
DisplayNameClaimType = IdentityServer3.Core.Constants.ClaimTypes.Name;
}
protected override Task<AuthenticateResult> PostAuthenticateLocalAsync(User user, SignInMessage message)
{
if (user.TwoFactorEnabled)
{
var twoFactorNeeded = false;
object httpContext;
if (_owinEnvironmentService.Environment.TryGetValue("System.Web.HttpContextBase", out httpContext))
{
var cookies = (httpContext as HttpContext)?.Request.Cookies;
if (cookies != null && !cookies.AllKeys.Contains(IdentityConstants.CookieNames.TwoFactorCompleted)) twoFactorNeeded = true;
}
if (twoFactorNeeded)
return Task.FromResult(new AuthenticateResult("/auth/sendcode", user.Id, user.DisplayName));
}
return base.PostAuthenticateLocalAsync(user, message);
}
}
UPDATED
Based on Brock's comment, I think I have a better solution.
// custom User Service
internal class UserService : AspNetIdentityUserService<User, string>
{
private readonly OwinEnvironmentService _owinEnvironmentService;
public UserService(UserManager userMgr, OwinEnvironmentService owinEnvironmentService) : base(userMgr)
{
_owinEnvironmentService = owinEnvironmentService;
DisplayNameClaimType = IdentityServer3.Core.Constants.ClaimTypes.Name;
}
protected override async Task<AuthenticateResult> PostAuthenticateLocalAsync(User user, SignInMessage message)
{
if (user.TwoFactorEnabled)
{
var owinContext = new OwinContext(_owinEnvironmentService.Environment);
var result = await owinContext.Authentication.AuthenticateAsync(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
if(result == null) return new AuthenticateResult("/auth/sendcode", user.Id, user.DisplayName);
}
return await base.PostAuthenticateLocalAsync(user, message);
}
}
// (in MVC controller) generate the 2FA security code and send it
public async Task<ActionResult> SendCode(SendCodeViewModel model)
{
// ...some code removed for brevity...
var token = await UserManager.GenerateTwoFactorTokenAsync(userId, model.SelectedProvider);
var identityResult = await UserManager.NotifyTwoFactorTokenAsync(userId, model.SelectedProvider, token);
if (!identityResult.Succeeded) return View("Error");
return RedirectToAction("VerifyCode", new { Provider = model.SelectedProvider, model.ReturnUrl, model.RememberMe });
}
// (in MVC controller) verify the code and sign in with 2FA
public async Task<ActionResult> VerifyCode(VerifyCodeViewModel model)
{
// ...some code removed for brevity...
var signInManager = new SignInManager<User, string>(UserManager, Request.GetOwinContext().Authentication);
if (await UserManager.VerifyTwoFactorTokenAsync(user.Id, model.Provider, model.Code))
{
await UserManager.ResetAccessFailedCountAsync(user.Id);
await signInManager.SignInAsync(user, model.RememberMe, model.RememberBrowser);
var resumeUrl = await env.GetPartialLoginResumeUrlAsync();
return Redirect(resumeUrl);
}
else
{
await UserManager.AccessFailedAsync(user.Id);
ModelState.AddModelError("", "Invalid code.");
return View(model);
}
}
I implemented the same for remember browser requirement however following statement return always null when we logout and login again.so twofactory step is not skipped..
var result = await owinContext.Authentication.AuthenticateAsync(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
all! I am using OData v4 building REST services. My tables have a GUID primary key.
My GET and POST requests are working fine. But the PUT, PATCH, and DELETE requests fail with 404.
I am not sure what the url should look like. I've tried these in Fiddler, all getting the 404. I have googled this quite a bit with no luck.

The request URL for PATCH, PUT and DELETE should be:
http://localhost/ershubrest/AppVersions(00000000-e90f-4938-b8f6-000000000000)
OData is using parenthesizes for addressing single entities using keys.
For more URL conventions, the OData V4 URL convention spec can be referred to: http://docs.oasis-open.org/odata/odata/v4.0/os/part2-url-conventions/odata-v4.0-os-part2-url-conventions.html
Try this:
http://localhost/ershubrest/AppVersions(guid'00000000-e90f-4938-b8f6-000000000000')
That should work!!
Odata V1-3 : http://localhost/ershubrest/AppVersions(guid'00000000-e90f-4938-b8f6-000000000000')
Odata V4 : http://localhost/ershubrest/AppVersions(00000000-e90f-4938-b8f6-000000000000)
I've tested Odata for 2 days
I ensure that !
