Authorized httpClient for calling WebApi #1218

3 years ago Answer

thank you for your response.

I see various classes in the namespace Volo.Abp.Http.Client.IdentityModel but cannot figure out how to 'hook in' to the events 'after succesful login' and 'after logout'

I'm pretty sure ABP must have some mechanism like that, for instance in it's UI to react to a logoff so the menu can change, the header in the top-right of the screen so the current userinfo can be shown (of not, after logoff).

I don't know how to explain more clearly.

I need an event or hook into the :

'after succesfull login'
'after logout'

Authorized httpClient for calling WebApi #1218

3 years ago Answer

Hi Mailiming,

I will look into the IAccessTokenProvider. But I think you missed the questions at the bottom of my message.

We need some way to know when the user has succesfully logged in

so we can (re)set the token in our Csla environment
We also need to know when the user has logged off

so we can clear the token in our Csla environment

I've looked, but I suppose that mechanism is burried deep within the ABP framework. Is there any way we can accomplish this ? maybe using some sort of eventhandler? I'm sure your UI is also reacting to these login/logoff events ?

Authorized httpClient for calling WebApi #1218

3 years ago Question

• ABP Framework version: v4.3 rc1 • UI type: Blazor • DB provider: EF Core • Identity Server Separated: no • ABP Commercial application

When running the blazor application locally I can see that calls to the HttpApi.Host have a httpheader Authorization with value ‘bearer ’.

<br> We will be using Csla as our businesslogic/data-layer for our application. Csla uses a ‘dataportal’ to retrieve data from the database, this dataportal call routes through the dataportalcontroller on the WebApi and is visible in swagger (https://localhost:44321/api/Blazor/DataPortal) just like all the other Abp methods like AbpApiDefinition (https://localhost:44321/api/abp/api-definition).

Csla ‘calls’ the DataPortal using its own httpClient, however thát httpclient does not have a defaultHttpHeader ‘Authorize’ we get an not-authorized error when calling the DataPortal method on the WebApi. We have been testing and when we sort of manually add defaultHttpHeader Authorize with the token to the httpClient when calling the DataPortal, it doés work :-)

I’m not sure but can we ‘get’ a ready to go (authorized) httpClient from ABP? I’ve tried using

[Inject] public HttpClient httpClient {get;set;}

But there is no ‘Autorize’ DefaultHttpHeader supplied in the resulting httpClient.

At this time we’d like to ask:

How can we hook into something like a ‘login-successful’ event and retrieve information (like the access_token) so we can store that for later use in the httpClient we use when calling the dataportal method on the webAPI?
How can we hook in to a ‘logout-successful’ kind of event so we can clear the access_token in our code.

Easy-CRM Blazor stops working after login #910

3 years ago Answer

Hi Alper,

Yes I did add our private Nuget address to the nuget.config. But in the appsettings.json there’s this line :

"AbpLicenseCode": "{PUT_YOUR_LICENSE_CODE_HERE}"

If I leave it in the file like that the app won’t start and leaves this message in the log file:

2021-02-26 09:43:29.782 +01:00 [ERR] ABP-LIC-0020 - License code not found! Ensure that your appsettings.json has "AbpLicenseCode" key with your license code. 2021-02-26 09:43:29.782 +01:00 [ERR] ABP-LIC-0008 - License check failed for 'Volo.Abp.Identity.Pro.HttpApi-v4.2.0.0'.

If I put our GUID in the AbpLicenseCode the app won’t start either and leaves a similar message in the log file. So I guess the GUID is not the license key. Where can we find the license key because we can't seem to find it on the page where out secret nuget url is.

Hi @Jurjen,

The downloaded version is old and we will update it asap. I'll write here again when we upload the latest version.

Hi Cotur,

Looking forward to that! Do you have any indication when this new version will be available ?

Easy-CRM Blazor stops working after login #910

3 years ago Question

Steps to reproduce the issue:

I have downloaded the easy-crm Sample application. Unzipped, followed the steps as explained on this page: https://docs.abp.io/en/commercial/latest/samples/easy-crm

Then I open the solution and run Volo.EasyCrm.Web, I log in to that application, then from VS-2019 I start the Volo.EasyCrm.Blazor project, The login page appears, I log in, then the screen goes gray and the nice 'C' keeps rotating.... that's where things stop working.

I have searched the docs / samples / support forum couldn't find a solution there.

I'm not sure what going wrong but this is one of the warnings I get.

** Could not find IdentityClientConfiguration for . Either define a configuration for  or set a default configuration.

And then at the end there's this Exception: Unhandled exception rendering component: VTable setup of type Blazorise.Snackbar.SnackbarStack failed

ABP Framework version: v4.0.0-rc3 (as in the easy-crm.zip, I've tried upgrading the Volo.Abp packages to 4.2.1 but the fails in vs-2019 every time)
UI type: MVC / Blazor
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): Tiered (MVC)
Exception message and stack trace:

The MVC application is working just fine, but the Blazor application is failing.

Can anyone shed some light on this problem ?

Kind regards, Jurjen
