通过RSpec发送自定义标头

Question

鉴于我的API消费者需要发送客户HTTP标头,如下所示:

# curl -H 'X-SomeHeader: 123' http://127.0.0.1:3000/api/api_call.json

然后我可以像这样在before_filter方法中读取这个标题:

# app/controllers/api_controller.rb
class ApiController < ApplicationController
    before_filter :log_request

private
    def log_request
        logger.debug "Header: #{request.env['HTTP_X_SOMEHEADER']}"
        ...
    end
end

到目前为止很棒.现在我想使用RSpec测试这个,因为行为有变化:

# spec/controllers/api_controller_spec.rb
describe ApiController do
    it "should process the header" do
        @request.env['HTTP_X_SOMEHEADER'] = '123'
        get :api_call
        ...
    end
end

但是,request在ApiController中收到的将无法找到标头变量.

same code使用HTTP_ACCEPT_LANGUAGE标头尝试时,它将起作用.自定义标头是否在某处过滤？

PS:网络上的一些例子使用request而不是@request.虽然我不确定当前Rails 3.2/RSpec 2.14组合中哪一个是正确的 - 但这两种方法都不会触发正确的行为,但两者都可以兼顾HTTP_ACCEPT_LANGUAGE.

Answer 1

好吧,对于人们来说可能为时已晚,但只是为了排队:

it 'should get profile when authorized' do
  user = FactoryGirl.create :user
  request.headers[EMAIL_TOKEN] = user.email
  request.headers[AUTH_TOKEN] = user.authentication_token
  get :profile
  response.should be success
end

只需使用适当的设置调用request.headers.

Answer 2

您可以get直接定义它.

get :api_call, nil, {'HTTP_FOO'=>'BAR'}

我刚刚验证它在控制台中工作.

Answer 3

RSpec请求规范在Rails 5中已更改，因此自定义headers和params现在必须使用键值哈希参数进行定义。例如：

在Rails 4中：

it "creates a Widget and redirects to the Widget's page" do
  headers = { "CONTENT_TYPE" => "application/json" }
  post "/widgets", '{ "widget": { "name":"My Widget" } }', headers
  expect(response).to redirect_to(assigns(:widget))
end

现在针对Rails 5：

it "creates a Widget and redirects to the Widget's page" do
  headers = { "CONTENT_TYPE" => "application/json" }
  post "/widgets", :params => '{ "widget": { "name":"My Widget" } }', :headers => headers
  expect(response).to redirect_to(assigns(:widget))
end
