How to capture an Object in the route (Route) of the PUT in a controller?

  • 772

is that I have a PUT and I want to capture the value of the field that I am going to update, but in the database in a SQL_Variantso to do so I have to send an object when sending it to the database, this is my PUT

[HttpPut("{empid}/{codigo}/{valor}")]
public async Task<IActionResult> Put(int empid, string codigo, [FromRoute]object valor)
{
    try
    {
        return Ok(await repository.UpdateAsync(empid, codigo, valor));
    }
    catch (Exception e)
    {
         return BadRequest(e.ToString());
    }
}

If I [FromRoute]object valorchange it to string or int here, it receives it correctly, but if I leave it in type Objectit will get Null and it doesn't work for me, how do I capture an object from the Controller route?

c#

    Define it as a string and it will receive all the types you send, then inside the controller code you can cast to really see what type it is

    [HttpPut("{empid}/{codigo}/{valor}")]
public async Task<IActionResult> Put(int empid, string codigo, [FromRoute]string valor)
{
    try
    {
        object persistValor = valor;

        int numberValor;
        bool isNumeric = int.TryParse(valor, out numberValor);

        if(isNumeric)
        {
          persistValor = numberValor;
        }

        return Ok(await repository.UpdateAsync(empid, codigo, persistValor));
    }
    catch (Exception e)
    {
         return BadRequest(e.ToString());
    }
}

    As you will see, you should see what type it is to assign the string that arrives or the value that is converted to a numeric if it is a number

    It could be seen if it is resolved with a custom ModelBinding , but I find it difficult if you send the value in the url, perhaps if you did it as part of bodythe put
