Search for several API ids. net core

Question

I do not know whether I was clear in the name however I have a doubt, I possess a route as follows:

/api/produto/v1/Aplicacao/filter

where this endpoint is a GET that passes a word as parameter and it searches the words that were passed.

The question is this, I have how to do the route something like /api/produto/v1/Aplicacao/filter/categoria/{id}, where the category id is optional and if I pass nothing in the category it uses only the route up /api/produto/v1/Aplicacao/filter and search the word that was passed by parameter?

Answer 1

A solution would be to pass a category id along with the words on the route /api/produto/v1/Aplicacao/filter and, if this id is null, search only by words.

To do this, just create a DTO with these two fields: a word list and a category id. This DTO would be passed as a parameter in the request within the controller.

DTO

public class YourDto
{
    public List<String> Palavras { get; set; }
    public int CategoriaId { get; set; }
}

Controller

public IActionResult yourMethodName([FromBody] YourDto dto)

So just check if it’s null the ID and if it is, just do the word search.
