Expand the api registration

Adapt the webapi to the new registration form.


Open UserForRegistration.cs and add the new fields and the relative Required attributes. We ignore the confirmPassword field, it is only for the client validation.

Add two readonly porperties Created and LastActive initialized to now in the constructor.

public class UserForRegistration
    public string Username { get; set; }

    [StringLength(30, MinimumLength = 8, ErrorMessage = "The password must be between 8 and 30 characters.")]
    public string Password { get; set; }

    public string Gender { get; set; }

    public string KnownAs { get; set; }

    public DateTime DateOfBirth { get; set; }

    public string City { get; set; }

    public string Country { get; set; }

    public DateTime Created { get; }

    public DateTime LastActive { get; }

    public UserForRegistration()
        this.Created = DateTime.UtcNow;
        this.LastActive = DateTime.UtcNow;

Open AutoMapperProfiles.cs and add a new profile. All the property names match, so no additional configuration is needed.

CreateMap<UserForRegistration, User>();


Open AuthController.cs and add a mapping.

//var userToCreate = new Models.User { Username = userForRegistration.Username };
var userToCreate = _mapper.Map<User>(userForRegistration);
var createdUser = await _repo.Register(userToCreate, userForRegistration.Password);

To remove the 201 and substitute it with a CreatedAtRoute open UsersController.cs and add a name to the route of GetUser

[HttpGet("{id}", Name="GetUser")]
public async Task<IActionResult> GetUser(int id)

Back in AuthController.cs change the return

//return StatusCode(201);
var userToReturn = _mapper.Map<UserForDetail>(createdUser);
return CreatedAtRoute("GetUser", new { id = userToReturn.Id }, userToReturn);

Test with Postman

Open Postman and edit the old POST used to create a user (or add a new one).

Change the body to the new structure. To avoid typing the JSON we can use the SPA, because in the register method we log a JSON.stringify of the form. For example:


Add a breakpoint in AuthController.Register() then attach the debugger.

Send the request. We must receive a 201 with the JSON for the new user

    "id": 12,
    "username": "mario",
    "gender": "male",
    "age": 18,
    "knownAs": "Mariolino",
    "created": "2018-07-19T09:41:10.1985833Z",
    "lastActive": "2018-07-19T09:41:10.1985834Z",
    "introduction": null,
    "lookingFor": null,
    "interests": null,
    "city": "Rome",
    "country": "Italy",
    "profilePhotoUrl": null,
    "photos": []

And in the headers there is the location for the new user, in my case: https://localhost:5001/api/Users/12
