How to receive querystring value in an action?

Question

I am creating an API with ASP.NET Core and would like to know how to do a search via querystring, in case the URL sees something like /api/programas?nome=teste

Like I would in my controller?

Example of my controller, in this case filtering by ID (just an example showing how I’m doing my endpoint):

public async Task<ActionResult<AppResponse>> GetAsync(Guid id)
{
    var app = await _programaHandle.GetAsync(id);
                     
    return Ok(app);
}

Answer 1

It is possible to declare a parameter in the action and use the attribute FromQuery.

public async Task<ActionResult<AppResponse>> GetAsync(Guid id, [FromQuery] string nome)
{
    var app = await _programaHandle.GetAsync(id);                 
    return Ok(app);
}
