How can I read the HTTP post request?

My question is familiar with: How should I format a JSON POST request to my rails app?

I am rookie in ruby on rails...just for 1 month study. I create a Rails with some easy funtions like CRUD. For now, i want to make some simple API for smartphone.

by use POSTMAN to test GET is OK. but POST always receive Status 422 Unprocessable Entity

what problems in my code... or does something i forget? thanks a lot...

The following are my codes.

controller:

  def index
    @users = User.all
    render :json => @users
  end

  # GET /beacons/1
  # GET /beacons/1.json
  def show
    @user = User.find(params[:id])
    render :json => @user
  end

  def create

    @user = User.new(user_params)
    @user.save

    respond_to do |format|
    format.json { render :json => @user }
    end
  end

  private

    def user_params
      params.require(:user).permit(:email, :password, :name)
    end

routes:

  namespace :api do
    namespace :v1 do
      resources :users, :defaults => { :format => :json } 
    end
  end

use rake routes:

  api_v1_users GET    /api/v1/users(.:format)            api/v1/users#index {:format=>:json}
               POST   /api/v1/users(.:format)            api/v1/users#create {:format=>:json}

my post:

{ "user": {"email": "2", "password": 2, "name": "2" } }

url:

http://localhost:3000/api/v1/users

It could be an issue with CSRF token, in application_controller.rb, try replacing

protect_from_forgery with: :exception

with 

protect_from_forgery with: :null_session

Also if possible post your question with the error log from rails s
