How to Set Up Multiple Web API Get

Question

I need to provide in my web api three forms of query: First Get with all "Getall" records, the second GET by id and a third GET with ribbon options, sent by client, e.g.: Name contains the letter "a" and address contains the word "bridge", I thought to send by queryString, but does not hit the correct action, incomplete example of how I thought to do the Get of filtered:

public HttpResponseMessage GetFiltrados() {
    string condicao = "";
    string[] filtros = Request.RequestUri.Query.Substring(1).Split('&');
    foreach (var filtro in filtros) {
        condicao += "";
    }
    if (reg != null) {
        return Request.CreateResponse(HttpStatusCode.OK, reg);
    } else {
        return Request.CreateResponse(HttpStatusCode.NotFound, "Registro não encontrado");
}

}

How do I create these three Get methods? I’m doing it right with Get with filters for REST default?
Ps.: My POST I did on the default, all in JSON, but GET didn’t know how to fix the ribbon.

Answer 1

I didn’t quite understand, but yours GET with the optional parameters can be this way:

[HttpGet,Route("api/Pessoas/ListarFiltrados")]
public IHttpActionResult ListarFiltrados(string? Nome= null, string? Sobrenome= null, int? idade= null)  
{
    var pessoas = db.Pessoas(Nome, Sobrenome, idade);
    return Ok(pessoas );
}

Notice that in front of each guy has the sign of ? which allows past attributes to be null.

The URL would look like this:

../api/ListarFiltrados?Nome=Diego&Sobrenome=Augusto&idade=23 

Another option would be to use Parameterbinding where you can pass an entire object to your Endpoint:

public IHttpActionResult ListarFiltrados([FromUri]Pessoa pessoa) {...}

Model Pessoa:

public class Pessoa
{
    public string Nome{ get; set; }
    public string Sobrenome{ get; set; }
    public int? Idade{ get; set; }
}

To queryString remains the same.
