How to store and call web API by name?

Question

I want to save the name of API to the database and call it after that. How can i do that?

Example:

I want to save the name of these APIs (Action1, Action2 and Action3) into the database and call it when I need (because I want to reorder or delete some actions in the UI):

public interface IMyAppService : IApplicationService
    {
        Task Action1();
        Task Action2(); 
        Task Action3();          
    }

So how can I store the API name as string in database and how to execute it after that? Should I store them like this?

"http://localhost/api/services/mpa/myApp/Action1"
"http://localhost/api/services/mpa/myApp/Action2"
"http://localhost/api/services/mpa/myApp/Action3"

Answer 1

You have 2 options:

1. save it by URL + use HttpClient, or

   • Pro: Transaction rollback is handled by ABP framework when an exception is thrown.
   • Con: You need to handle web request, authorization and deserialization of response.

2. save it by AppService and method names + use reflection.

   • Pro: Authorization is handled by ABP framework when in IAbpSession.Use() block.
   • Con: You may need to handle transactions and exceptions ⇒ logic leaks to the caller.
