Service to Service communication #8012

  • ABP Framework version: 8.2.1
  • UI Type: Angular
  • Database System: EF Core (MySQL)
  • Tiered (for MVC) or Auth Server Separated (for Angular): yes Hi There,

I've implemented microservice to microservice synchronous communication as stated here. The soulution works just fine. I'm able to get data from cross service but every time I hit the endpoint on other service I see a new token is generated and it is causing my OpenIddictTokens just keeps increasing. Can't the once generated token be re-used again for next service call? I see the token is generated with 1 hour of expiration but next service call(Same endpoint) does not consider existing token and generates the new token.

Thanks Krishna

    Hi,

    The services are stateless; it will not store the token.

    Or you can consider to integration services https://abp.io/docs/latest/framework/api-development/integration-services

    Hi liangshiwei,

    Thanks for the quick reply. If I moved to Integration Service do I still need aa access_token while communication from service to service? When I followed intergration implemntation I gets UnAuthorized exception.

    Thanks Krishna

    Hi

    Integration services don't need acccess_token.

    Could you share your code?

    Hi liangshiwei,

    Here is the code.

    VendorModule:

    public interface IVendorIntegrationService : IApplicationService, ITransientDependency
{
    Task<ListResultDto<VendorDto>> GetAllAsync();
}

[Authorize(VendorManagementPermissions.Vendors.Default)]
[IntegrationService]
public class VendorIntegrationService : ApplicationService,IVendorIntegrationService
{
    private readonly VendorManager _vendorManager;
    private readonly IRepository<Vendor, int> _vendorRepository;

    public VendorIntegrationService(VendorManager vendorManager, IRepository<Vendor, int> vendorRepository)
    {
        _vendorManager = vendorManager;
        _vendorRepository = vendorRepository;
    }
    [Authorize(VendorManagementPermissions.Vendors.Default)]
    public async Task<ListResultDto<VendorDto>> GetAllAsync()
    {
        var vendors = await _vendorRepository.GetListAsync();
        return new ListResultDto<VendorDto>(
            ObjectMapper.Map<List<Vendor>, List<VendorDto>>(vendors)
        );
    }
}

[IntegrationService]
public class VendorIntegrationController:IVendorIntegrationService
{
    private readonly IVendorIntegrationService _vendorIntegrationService;
    public VendorIntegrationController(IVendorIntegrationService vendorIntegrationService)
    {
        _vendorIntegrationService = vendorIntegrationService;
    }
    public Task<ListResultDto<VendorDto>> GetAllAsync()
    {
        return _vendorIntegrationService.GetAllAsync();
    }
}

VendorManagementApplicationModule:AbpModule

 private void ConfigureIntegrationServices()
 {
     Configure<AbpAspNetCoreMvcOptions>(options =>
     {
         options.ExposeIntegrationServices = true;
     });
 }

    If I'm trying to access this from web-gateway I get 404 not found exception but same works from Vendor service swagger.

    Accounts Payable Module:

     private readonly IVendorAppService _vendorAppService;
 private readonly IVendorIntegrationService _vendorIntegrationService;
 public SampleAppService(IVendorAppService vendorAppService, IVendorIntegrationService vendorIntegrationService)
 {
     _vendorAppService = vendorAppService;
     _vendorIntegrationService = vendorIntegrationService;
 }
 
  public async Task<ListResultDto<VendorDto>> GetVendorFromAPIntegration()
  {
      return await _vendorIntegrationService.GetAllAsync();
  }

    From Accounts payable when I make request first I got 404 so I added Remoteservice configuration in appsettings.json as below.

     "RemoteServices": {
   "AbpIdentity": {
     "BaseUrl": "http://localhost:44377/"
   },
   "Default": { //This is the URL of web-gateway. Which will be used to call other services(Vendor Service).
     "BaseUrl": "http://localhost:44397/",
     "UseCurrentAccessToken": "false"
   },
   "VendorService": {
     "BaseUrl": "http://localhost:44323/",
     "RemoteName": "VendorService",
     "UseCurrentAccessToken": "true"
   }
 },

    After adding this I started getting 401 unauthorized. 10/3/2024 11:25:08 PM [Information] Request starting "HTTP/1.1" "GET" "http"://"localhost:44305""""/api/ap-management/sample/vendor-from-aPIntegration""" - null null 10/3/2024 11:25:09 PM [Information] Executing endpoint '"CastandCrew.PSL.AccountsPayableManagement.Samples.SampleController.GetVendorFromAPIntegration (CastandCrew.PSL.AccountsPayableManagement.HttpApi)"' 10/3/2024 11:25:09 PM [Information] Route matched with "{area = \"accountsPayableManagement\", action = \"GetVendorFromAPIntegration\", controller = \"Sample\", page = \"\"}".

    Hi,

    You should not use Authorize for the integration service.

    If you need to use Authorize, you don't needs to change anything.

    HI,

    BTW, ABP will try to get the token from the cache; it won't get a new token every time. https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.IdentityModel/Volo/Abp/IdentityModel/IdentityModelAuthenticationService.cs#L84

    Hi,

    The whole point is it's not picking it from cache and generating the new one on every request. I hit the service continueously and you can see the tokens are generated for each request.

    I see this tokens are even loaded in my cache but the Payload is null.

    Hi,

    May I ask, are you running in development env? For development environments, the cache expiration time is 5seconds

    Yes it's development environment but I use hosted Auth server and Identity service. Is there any way to change expiration?

    Hi,

    You can usually ignore it in the development environment, or you can change the current environment.

    Unfortunately there is currently no configuration to change the cache expiration time during development
