Hi,
to implement a custom api for external use i want to implement hmac authentification via a custom attribute like this:
namespace xxx.Api.Controllers
{
[Audited]
[MeHmacAuthentication]
public class ExportController : MeApiControllerBase
...
In a standalone mvc app all worked, but now i migrate the whole project to abp style.
In the implementation of the attribute i do: (McHmacAuthenticationAttribute is a common baseclass doing the most things)
namespace xxx.Authentication
{
public class MeHmacAuthenticationAttribute : McHmacAuthenticationAttribute
{
private readonly IMeApiKeyAppService _apikeyService;
public MeHmacAuthenticationAttribute(IMeApiKeyAppService apikeyService)
{
_apikeyService = apikeyService;
ListResultOutput<MeApiKeyListDto> keys = _apikeyService.GetKeys();
...
but _apikeyService does not get injected. I tried to manually register:
public class MeApiModule : AbpModule
{
public override void PreInitialize()
{
Configuration.BackgroundJobs.IsJobExecutionEnabled = false;
}
public override void Initialize()
{
IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
IocManager.Register<IMeApiKeyAppService, MeApiKeyAppService>(DependencyLifeStyle.Transient);
}
public override void PostInitialize()
{
base.PostInitialize();
}
but this did not change anything.
can you please guide me to thi right direction to do this
thanks in advance Martin

Hi,
Does your MeHmacAuthenticationAttribute have a parameterless constructor ? Otherwise you couldn't use it like this [MeHmacAuthentication] I think :).
In MVC you cannot inject anything to attributes. You have two options,
1 - Resolve IMeApiKeyAppService manually
var meApiKeyAppService = IocManager.Instance.Resolve<IMeApiKeyAppService >();in your attribute when you need it. Then you should release it after you are done with it like this
IocManager.Instance.Release(meApiKeyAppService );2 - You can create a web api filter and add it to web api filters. For this one, you can take a look at AbpApiAuditFilter in ABP's source code and it's usage.
