Rails APIを使ってjsonファイルを投稿しようとしています。 私が修正しようとしましたが、この私の問題 を実行することはできません。

Student.rb

これは私の学生モデル

class Student < ApplicationRecord 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 
end 

Application_controllerです

私は問題を解決しました=> null_se ssion

class ApplicationController < ActionController::Base 

    protect_from_forgery with: :null_session 

end 

Student_controller

class Api::StudentsController < ApplicationController 
    def index 
    students = Student.all 
    render json: students, status: 200 
    end 
    def show 
    response_with Student.find(params[:id]) 
    end 
    def create 
    student = Student.new(student_params) 
    #if you save successfully than response with json data and status code 201 
    if student.save 
     render json: user, status: 201, location: student 
    else 
     render json: {error: user.errors}, status: 422 
    end 
    end 
    private 
    def student_params 
    params.require(:student).permit(:name, :score) 
    end 
end 

router.rb

Rails.application.routes.draw do 
    devise_for :students 
    namespace :api, path: '/',constraints: {subdomain: 'api'} do 
    resources :students, only: [:index, :show, :create] 
    end 
end 

しかし、私は

{"student": {"name": "Duong", "score": "10"}} 

持たをapi.1312100.com/students/するポストを送りますエラー：

500 internal server error 

Answer 1

skip_before_action :verify_authenticity_token 

Answer 2

カーリング：Api::StudentsControllerアドオンで

curl -i -H "Accept: application/json" -H "Content-type:application/json" -X POST -d '{"student": {"name": "Duong", "score": "10"}}' http://api.1312100.com/students/ 

アプリケーションコントローラ

class ApplicationController < ActionController::Base 
    protect_from_forgery with: :exception, if: Proc.new { |c| c.request.format != 'application/json' } 
    protect_from_forgery with: :null_session, if: Proc.new { |c| c.request.format == 'application/json' } 
end
