How to integrate login/registration pages in angular project?
When I run the angular project and click on Login Page, it redirect to the Identity Server URL. We need to use the same domain where our Angular project is hosted. We are also using Volo.Account npm package in angular project so login page should be served by https://localhost:4200/account/login url.
I read the documentations and articles but no article found to integrate login in Angular UI.
Here is the article to customize the login page for MVC razor page and we need to customize the login page for Angular.
https://community.abp.io/articles/how-to-customize-the-login-page-for-mvc-razor-page-applications-9a40f3cd
ABP Framework version: 4.4.0
UI type: Angular
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): yes
I am assuming that you are using ASP.NET to serve an API for your Angular frontend that is somehow secured by Identity Server.
In that case, you should create a AuthController with Login and Logout endpoints that will be called by a view you just normally implement in Angular. You can use JWT for authentication on subsequent API calls. https://docs.identityserver.io/en/latest/topics/apis.html, e.g. a JSON token will be returned by the login endpoint.
I got the solution from the below URL.

I have an asp.net core web application that using OpenIddict. It works fine and users can login.
Now I want to add web.api hosted on separate subdomain, but because the user is already authenticated I want to somehow share that authentication.
Is it possible? How can I do it? I see in the examples for OpenIddict user have to authenticate again, but I do not want that.
My Setup:
ASP.NET Core Web App: app.domain.com
OpenIddict server: login.domain.com
Web API .net Core App: api.domain.com (that is new requirement)
My web application has views that display data from controllers, I want to add extra javascript logic, and I can have web.api as part of the asp.net core domain: app.domain.com/api/
in that case, it works, the authenticated shared between web application and API,
but my goal is to have web.api on a separate subdomain: api.domain.com
I know I have to create a Bearer token, but it is not clear how to do it without authenticating the user again. So I want somehow share ASP.NET Core web application authentication to access api.domain.com
Can you please point me in the right direction? Where to start looking?
I have a hosted Blazor WebAssembly App and I tried to scaffold identity server in the project App.Server. It's working but now I have a mix of cshtml view files in the App.Server (which was intended to be only a asp net core web api). I found hard to integrate the Blazor UI and cshtml files to have a nice user experience.
I was expecting to have a separate pure web api with identityserver api and Blazor taking care of the pages/views and api calls. Is it possible to move those cshtml to Blazor and manage the pages from there or the scaffolding has been done that way because is not?
No, you can't move those Razor Pages pages to your front-end Blazor. But you can design them in such a way as to create the impression that, when the user, for instance, is redirected to the Login page, the Login Razor Pages page is part of the Blazor front-end. I've seen an example of that, and must admit that I couldn't discern it without seeing the source code.
Having a dedicated Web Api project or having Web Api end points in your Blazor server project has nothing to do with the Identity UI not being part of the Blazor front-end.

You can create a Blazor WebAssembly stand alone project, add a Web Api project, and an IdentityServer4 project, in which case, the flow of OpenID Connect is such that your users wanting to log in are redirected to the Login page provided by the default template of the project, but you can still design the pages to look as though they are part of the Blazor front-end.
The only viable solution that can satisfy your whims is to use Bearer Authentication; that is your Web Api produces Jwt token for users, which are passed to your front-end, and stored in the local or session storage. In that case, your Login page can be a Razor component that gather credentials from the user, and pass them to the Web Api appropriate end points via the Fecth API (this is the HttpClient service in Blazor)... This was the method we adopted before the Blazor team have created the current authentication system of Blazor. Personally I wouldn't recommend one to do that unless he is proficient in Blazor and other fields, and he's ready to invest a great deal of time for developing it. I guess your solution should be deception: let the user think that he's never left the space of the Blazor SPA...
I have a Blazor WebAssembly app. It's self contained and doesn't use any web API calls. I'd like to add authentication using my existing Azure AD B2C tenant so that only registered users can access the app.
Microsoft says that:
In Blazor WebAssembly apps, authorization checks can be bypassed because all client-side code can be modified by users.
So rather than host my Blazor app statically (the standalone model), I'd like to use the ASP.NET Core hosted model (so an ASP.NET Core app serves the Blazor app to clients). That way I can do the authentication/authorization on the server - if the user is registered and is allowed access to the app, the ASP.NET Core app serves them the Blazor app. If they aren't, they can be shown an error page or be redirected.
The issue is that I'm not sure how to implement this.
When I create a new Blazor WebAssembly Hosted app from the template in Visual Studio 2019, it creates three projects. A shared project, the Blazor project, and a Server project. The Server project has a reference to the Blazor project. This line appears at the end of the Configure method of Startup.cs:
endpoints.MapFallbackToFile("index.html");
This seems to be the thing that makes it serve the Blazor app to the client. I'm not sure how I can add authentication/authorization to this. I tried modifying this line to look like this:
endpoints.MapFallbackToFile("index.html").RequireAuthorization();
But the app still loads without redirecting to a login screen first.
There is some Microsoft documentation called "Secure an ASP.NET Core Blazor WebAssembly hosted app with Azure Active Directory B2C" which sounds like it's what I need, but it's actually still doing the authentication in the Client app while also securing API calls to the Server app (which I don't need).
Is there any way to accomplish what I'm trying to do - authenticating the user on the server before serving the Blazor app, rather than doing that authentication in the Blazor app itself?
The answer was really simple. Actually, the RequireAuthorization() call does work. If you're already logged in to B2C you won't be redirected to the login page first (and, in Edge at least, it doesn't even visibly redirect to B2C first before redirecting back to the app, hence the confusion). But if I load the page in a private browser window I am redirected to the B2C login page - so it must be working as intended.
For future reference, the answer to the title question is:
Add auth to the ASP.NET Core Server app if you haven't already.
In the Server app, add a project reference to the Blazor app.
Add the following line to the UseEndpoints call inside the Configure method in Startup.cs:
endpoints.MapFallbackToFile("index.html").RequireAuthorization();
I'm using angular2 as a front-end. My Back-end is ASP.NET Core and I am using it as a Restful Web API. How can I authenticate credentials from angular against a local active directory?
Depending on the version of ASP.NET you could implement the ASP.NET Membership or Identity which can connect to AD.
You should easily find various examples of these.
I have recently looked at Auth0, which means you can integrate a variety of ways, front or back-end.

I want to implement authentication and authorization in my MVC and Web API projects.
For cross browser and mobile access, we are implementing Web API into our project. In our Views, we are using normal controllers. For data we are using API controllers. How can I achieve role-based access and authorization in ASP.NET MVC 5?
I have added the authentication tag to the web.config. When I run the application, I'm getting the following error:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
