请求规格：如何通过POST请求创建新用户？

Question

鉴于以下控制器：

class UsersController < ApplicationController 
     include ActionController::ImplicitRender 
     include ActionController::ParamsWrapper 

     wrap_parameters format: :json 
     # POST /users 
     # POST /users.json 
     def create 
     #@user = User.new(params[:user]) 
     @user = User.new(user_params) 

     if @user.save 
      render json: @user, status: :created, location: @user 
     else 
      render json: @user.errors, status: :unprocessable_entity 
     end 
     end 

     private 

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

我能够通过发送CURL一个HTTP POST请求创建一个新用户：

curl -H "Content-Type: application/json" -d '{"name":"xyz","email":"xyz@example.com"}' http://myrailsapp.dev/users 

我怎么会工艺的要求相应的规范呢？

# spec/requests/users_spec.rb 
    describe "POST /users" do 
    it "should create a new user" do 

     # FILL ME IN 

     expect(response).to have_http_status(200) 
    end 
    end 

我的第一个想法是添加以下内容：

post users_path, body: '{"name":"xyz","email":"xyz@example.com"}' 

导致的400

Answer 1

这里是你的答案：

post users_path, :user => {"name":"xyz","email":"xyz@example.com"}, { 'CONTENT_TYPE' => 'application/json'} 

Answer 2

HTTP状态的问题是在头内，你需要确保它指定JSON内容！

post users_path, '{"name":"xyz","email":"xyz@example.com"}' , { 'CONTENT_TYPE' => 'application/json', 'ACCEPT' => 'application/json' } 

希望能为你效劳！ 干杯，一月
