在 Rspec 中传递 JSON POST 请求的两个参数

Question

我有一个 JSON Rails 4 API，我正在使用 Rspec 进行测试。我在传递给帖子中的两个参数时遇到了麻烦：创建请求。

这是当前的测试：

 require 'spec_helper'
  module Api
    module V1
      describe Api::V1::ProductsController, type: :controller do

        before do
          @api_app = FactoryGirl.create(:api_app, request_origin: "0.0.0.0")
          @store = FactoryGirl.create(:store)
        end

        after(:all) do
          Product.all.each {|l| l.destroy}
          ApiApp.all.each {|a| a.destroy}
        end

        describe "POST 'create' " do
          context "Creates a product with the correct parameters" do
            it "returns a successful response string with success message" do
              json = { :format => 'json', product:{first_name:"Hello", last_name:"You", email:"email@email.edu",street1:"103 ABC Street", city:"Pittsburgh", phone:"4125361111", store_id:@store.id, state:"CA", country:"United States", organization:"ABC", organization_type: "Org"}}
              post :create, json, access_token: @api_app.access_token 
              expect(response).to be_success
              expect(response.body).to include("Product created")
            end
          end

          context "Incorrect parameters to create a product" do
            it "returns a failure response when a parameter is missing" do
              json = { :format => 'json', product:{first_name:"Hello", last_name:"You", email:"email@email.edu",street1:"103 ABC Street", city:"Pittsburgh", phone:"4125361111", store_id:@store.id, state:"CA", country:"United States", organization:"ABC"}}
              post :create, json, access_token: @api_app.access_token 
              expect(response).to be_success
              expect(response.body).to include("Product failed to create")
            end
          end
        end
      end
    end
  end

我需要json和access_token就行了：

post :create, json, access_token: @api_app.access_token

但是请求忽略了第二个参数（我可以切换它们的位置来确认）。我如何对帖子进行措辞以便读取两个参数？

您正在寻找的是Hash.merge(other_hash)。您可能想阅读 Hash 类，因为大约 50% 的 Ruby 编程是关于哈希操作（恕我直言）。

这是您在规范中使用它的方式：

require 'spec_helper'

# You don't need to put the spec inside your module! 
# It just makes it harder to read!
describe Api::V1::ProductsController, type: :controller do

  before do
    @api_app = FactoryGirl.create(:api_app, request_origin: "0.0.0.0")
    @store = FactoryGirl.create(:store)
  end

  after(:all) do
    Product.all.each {|l| l.destroy}
    ApiApp.all.each {|a| a.destroy}
  end

  describe "POST 'create' " do

    # DRY up the parameters
    let(:params){
      access_token: @api_app.access_token 
      format: 'json'
    }

    # Even better is to use fixures or factories for this.
    let(:product_params) {
      first_name:"Hello", 
      last_name:"You", 
      email:"email@email.edu",
      street1:"103 ABC Street", 
      city:"Pittsburgh", 
      phone:"4125361111", 
      store_id:@store.id, 
      state:"CA", 
      country:"United States", 
      organization:"ABC"
    }

    context "Creates a product with the correct parameters" do
      it "returns a successful response string with success message" do
        product = product_params.merge(organization_type: "Org")
        post :create, params.merge(product: product)
        expect(response).to be_success
        expect(response.body).to include("Product created")
      end
    end

    context "Incorrect parameters to create a product" do
      it "returns a failure response when a parameter is missing" do
        product = product_params.merge(organization_type: "ABC")
        post :create, params.merge(product: product)
        expect(response).to be_success
        expect(response.body).to include("Product failed to create")
      end
    end
  end
end

但是您的规范包含错误：

context "Incorrect parameters to create a product" do
  it "returns a failure response when a parameter is missing" do
    product = product_params.merge(organization_type: "ABC")
    post :create, params.merge(product: product)
    expect(response).to be_success #! it should not be a success!
  end
end

expect(response).to be_success 实际上意味着响应应该具有 200 OK HTTP 响应代码 - 但如果缺少参数，您应该返回 a 400 Bad Request。正确的期望是：

expect(response).to have_http_status :bad_request

我认为您应该在帖子中发送一个哈希值。请尝试以下操作：

post :create, json.merge!(access_token: @api_app.access_token)
