Calling Application Service from BackgroundJobs #1292

andis created

We are planning to create an import module. Actually by import module is nothing more than just an action to let user trigger Application Service Action repeatly with different input. Our design is to let users upload an excel, define the application service and its method they want invoke.. After that, background job can impersonate that user to do the input(all validations, audit logs and permissions are based on the uploading users). Is there anyway to achieve this?

    While we haven't tried such a service, it should be possible. You will need to implement IAbpSession for that, since authorization gets userid/tenantid from AbpSession. After implementing your solution, share here so we can review it.

    What do you mean by "Proxied Application Service"? You mean "Castlw dynamic proxy"? If so, it's automatically done when you use dependency injection and inject app service by it's interface.

    But.. as I see your case is a bit different. Creating a new session implementation is not possible, because it will also replace the session in web application since your background job is working in the same process.

    Current session gets userId and tenantId from cookies. You, somehow, should change it to be manually changable for an async flow. You can try AsyncLocal for that.. but this may be a bit complicated and requires some multithreading knowledge. But I could not find another way yet.

    There are a few interceptors for App services:

    • Authorization: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp/Authorization/Interceptors/AuthorizationInterceptorRegistrar.cs#L20">https://github.com/aspnetboilerplate/as ... rar.cs#L20</a>
    • Validation: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp/Runtime/Validation/Interception/ValidationInterceptorRegistrar.cs#L17">https://github.com/aspnetboilerplate/as ... rar.cs#L17</a>
