asp.net core webapi with single endpoint with multiple conditions

Question

User1838940990 posted

Hi All,

hope you all are safe.

We have asp.net core web api with multiple endpoints for different  categories 

eg :    ww.url.com/category1/create

          ww.url.com/category2/create

Since we don't to expose the category name , planning to expose single controller and category will be passed a field in parameter and palln to pu if condition to service the request 

ww.url.com/create 

[HttpPost("create")]

public IActionResult Create( category category )

{

     if category.Type ==category1

{

category1.service.create();

}

elseif category.Type ==category2

{

category2.service.create();

}

}

We are going to have more than 8-10 conditon now and it can grow 

or is there any pattern to handle these type of requirement like this ?

have a nice day ahead

thanks,

Rather than putting a lot of “if - else if- else” codes to select the category in the action method why don't you develop the Service class so that the Create method in it receives the argument "category" and return the object according to the argument given in the controller?

Thanks Bruce, I am not much familiar with this pattern.

Seems like this is something I am looking for, let me have look at this and update you if  I can implement this in my api
