RSpec post 操作的请求规范包括 headers 导致参数被删除

Question

我想弄清楚为什么我不能在请求规范中同时使用参数和 headers。

什么有效：

RSpec.describe  Api::V1::UsersController, :type => :request  do

  before { host! 'api.localhost:3000'}

  let(:params) {
    {
      "user": {
        "identifier_for_vendor": "BD43813E"
      }
    }
  }

  describe 'Post /users' do
    context 'when request is valid' do
      before {
        post api_users_path,
        params: params
      }

      it "is successful" do
        expect(response).to be_successful
      end
    end
  end
end

什么没有：

RSpec.describe  Api::V1::UsersController, :type => :request  do

  let(:params) {
    {
      "user": {
        "identifier_for_vendor": "BD43813E"
      }
    }
  }

  let(:headers) {
    {
      "host": "api.localhost:3000",
      "Accept": "application/vnd.domain_name.v1",
      "Content-Type": "application/vnd.api+json",
      "X-API-Key": "fake087uakey"
    }
  }

  describe 'Post /users' do
    context 'when request is valid' do
      before {
        post api_users_path,
        params: params,
        headers: headers
      }

      it "successful" do
        expect(response).to be_successful
      end
    end
  end
end

以上失败，返回错误：

  1) Api::V1::UsersController Post /users when request is valid is successful 
     Failure/Error: params.require(:user).permit(:identifier_for_vendor)

     ActionController::ParameterMissing:
       param is missing or the value is empty: user

需要 headers，因为必须确保请求中包含有效的 api-keys。

希望就我所缺少的内容提供反馈。谢谢

Answer 1

所以问题与 params 和 headers object 的创建方式有关。

参数：

我通过了：

  {"user": {"identifier_for_vendor": "OFJPJ"} }

正确的object是：

  {:params=>{:user=>{:identifier_for_vendor=>"OFJPJ"}}}

Headers:

我通过了：

    {
      "host": "api.localhost:3000",
      "Accept": "application/vnd.domain_name.v1",
      "Content-Type": "application/vnd.api+json",
      "X-API-Key": "fake087uakey"
    }

正确的object是：

{
  "headers" => {
    "host" => "api.localhost:3000", 
    "Accept" => "application/vnd.domain_name.v1", 
    "X-API-Key" => "api_key"
  }
}

最终解决方案如下所示：

RSpec.describe  Api::V1::UsersController, :type => :request  do

  describe 'Post /users' do
    context 'when request is valid' do


      before do
        post api_users_path,
        :params => params,
        :headers => headers
      end


      it "is successful" do
        expect(response).to be_successful
      end

      it "returns a data of type user" do
        expect(json_data["type"]).to eq("user")
      end
    end
  end
end

解决这个问题的关键是阅读 documentation 并意识到我的格式错误。
