学生.rb

这是我的学生模型

Student.rb

This is my student model

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

应用程序控制器

我有修复异常 => null_session

Application_controller

I have fix excetion => null_session

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

路由器.rb

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

但是，当我向 api.1312100.com/students/发送帖子时

But, when I send a post to api.1312100.com/students/

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

有错误:

500 internal server error

推荐答案

在 Api::StudentsController 中添加:

skip_before_action :verify_authenticity_token
