What I have tried:

[Produces("application/json")]
    [Route("api/Employee")]
    public class EmployeeController : Controller
    {
[HttpPut("{id}")]
        public IActionResult PutEmployee(int id, [FromBody] Employee employee)
        {
        
       
         
                if (id != employee.EmployeeId)
            {
                return BadRequest();
            }

           

            try
            {
                _repository.Update(employee);
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!EmployeeExists(id))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }

            return Ok();
        }

推荐答案

https ：// localhost：44326 / api / Employee / 5



在邮递员中选择动词Put并使用斜杠5（/ 5）传递id。



无需明确提及操作和id。

https://localhost:44326/api/Employee/5

Select verb "Put" in postman and pass id with just slash5 (/5).

No need to mention operation and id explicitly.
