Now create HTTP function requests for the profiles. 

Here is the function for creating a profile's POST request:

// New Profile registration
@PostMapping("/profile/new")
fun registerUser(@RequestBody profile: Profile): Any {
    if (!userExist.isUserExist(profile.username)) {
        profile.password = passwordEncoder.encode(profile.password)
        profileRepository.save(profile)
        return profile
    }
    return "{"duplicate": "${profile.username} is taken. Try another"}"
}

Here is the function for creating a profile's GET request:

// Get Profile by ID
@GetMapping("/profile/{id}")
fun getUserById(@PathVariable("id") id: Long): Any {
    return profileRepository.findById(id)
}

Here is the function for creating a profile's PUT request:

//     Update Profile by ID
@PutMapping("/profile/{id}")
fun updateUserById(@PathVariable("id") id: Long, @RequestBody mUser: Profile): Any {
    val profile = profileRepository.getOne(id)
    if (mUser.firstName != null) profile.firstName = mUser.firstName
    if (mUser.lastName != null) profile.lastName = mUser.lastName
    if (mUser.contactNumber != null) profile.contactNumber = mUser.contactNumber
    if (mUser.city != null) profile.city = mUser.city
    if (mUser.country != null) profile.country = mUser.country
    return profileRepository.save(profile)
}

Here is the function for creating a profile's DELETE request:

// Delete Profile by ID
@DeleteMapping("/profile/{userId}")
fun deleteUserById(@PathVariable("userId") userId: Long): Any {
    deletePCLRepository.deleteAllUsersInfoByUserID(userId)
    return profileRepository.deleteById(userId)
}
