Implement POST /users

[WThamira]

HTTP POST request to http://localhost:8090/api/users should create a new user.

Request schema #1:

{
    "username":"admin",
    "email" : "admin@letmehack.lk"
    “password”: “password”
}

If the password is not set, you should randomly generate a password in the backend.

Response schemas:

Status 201: Return if the user was successfully created.

{
 “self”: “http://localhost:8090/api/users/{user_id}”,
 “email”: “admin@letmehack.lk”
}

Status 400: Return if email is not set.

Status 409: If the user already exists.

{
  "status": 409,
  "message": "An user with email: {email} already exists.",
  "developerMessage": "User creation failed because the email: {email} already exists."
}

Request schema #2

{
    "username":"admin",
    “email”: “admin@letmehack.lk”
}

Here the password is not set.

Response schema

Status 201: Return if the user was successfully created.

{
    “self”: “http://localhost:8090/api/users/{user_id}”
    “email”: “admin@letmehack.lk”
}

Note
Placeholders {email}, {user_id} should contain actual values.
It's recommended that you use UUID as the primary key.
