Trying to reach API using Content-Type application/x-www-form-urlencoded

Question

I am building API restful server using dotnet core framework. I added my controller and trying to reach an endpoint using postman.

I have 2 problems

• Problem 1

  // POST api/user
  [HttpPost]
  [Authorize()]
   public async Task<IActionResult> Post([FromBody]UserModel user)
  {
  }
  

Unless I send the request from postman as application/json by typing raw json, I can't reach this endpoint if I use application/x-www-form-urlencoded instead I always get 415 unsupported media type

• Problem 2

  // POST api/user/avatar
  [HttpPost]
  [Authorize()]
  [Route("avatar")]
  public async Task<IActionResult> Post([FromBody]UserModel user, [FromBody]IFormFile file)
  {
  }
  

I don't know how to reach such an endpoint using postman

Answer 1

In problem 1 you just need to use FromForm attribute instead of FromBody. As for second, i think will be easier write simple unit test or use Swashbuckle, it has great interface for such requests

Answer 2

You can use Consumes attribute like that:

// POST api/user
[HttpPost, Consumes("application/x-www-form-urlencoded")]
[Authorize()]
public async Task<IActionResult> Post([FromBody]UserModel user)
{
}
