- ABP Framework version: v5.1
- UI type: Blazor
- DB provider: EF Core
- Tiered (MVC) or Identity Server Separated (Angular): No
- Exception message and stack trace:
- Steps to reproduce the issue: I would like to build API that can access from client (chrome plugin), with some basic functions like : login, logout, CRUD to some data table and that using JWT to authenticate. Can I use IdentityServer4 and its API or I should create new module for it? If so can you give me some document that I can refer?

hi
ABP's identity module uses cookies as the authentication scheme by default.
You can use the Identity Server module. You can use the Authorization Code flow in the chrome plugin to get the access token.

Thanks @maliming,
At server, what is interface or class that I need to use to verify user? I tried to use IdentityUserAppService but it does not work. Can you give a sample code to allow user login?

You can refer to identity and account module source code.

Yes that is what I need, can you send me these link to source code?

Hi Maliming again, I have a question related to JWT. I saw in our solution there is a configure of JWT already
So that I can not add JWT bear configure (I have code to use Security key).
In this case, how can I generate token to use for API? The token generated by using security key is not working -

This is just a jwt authentication scheme, you can add a custom jwt or cookies authentication scheme.

But when I add my custom JWT bear, it gives error so I think I can only use this default or custom JWT, is that right? Autofac.Core.DependencyResolutionException: An exception was thrown while activating λ:Microsoft.Extensions.Hosting.IHostedService[] -> Microsoft.AspNetCore.Hosting.GenericWebHostService -> Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer -> Microsoft.AspNetCore.Authentication.AuthenticationSchemeProvider. ---> Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(Microsoft.Extensions.Options.IOptions

System.InvalidOperationException: Scheme already exists: Bearer at Microsoft.AspNetCore.Authentication.AuthenticationOptions.AddScheme(String name
You can use a different scheme name.

Thank you I can get it work, but what is different about name? If I put second as default, it works (as image below) But if i put second with "CustomJWT" it does not work, and return 302 Found error. Does it take only default Bearer?

You need to set the Authority.

I have it in appSetting.json
But if I move set CustomJWT here, it works fine with my customJWT but I don't think it works for Authority

I suggest you first understand JWT authentication in asp net core.
https://www.google.com/search?q=JWT+authentication+in+asp+net+core.&oq=JWT+authentication+in+asp+net+core.&aqs=chrome..69i57.256j0j7&sourceid=chrome&ie=UTF-8

Yes I can get my JWT works, but I dont want to hurt current Jwt with Authority, so i want to keep them both. if I configure like that it will work with my JWT token (not sure Authority work or not)
But if I configure
It will not work with my JTW token.
Can I make it work for both? -
