Rspec:在路由规范中添加一些标头请求

问题描述

我正在开发一个 Rails 应用程序，它有一个 JSON 格式的 REST API 和版本(根据这个优秀的 Ryan 演员表:http://railscasts.com/episodes/350-rest-api-versioning).

I'm working on a Rails application having a REST API in JSON format and versioned (according to this excellent Ryan's cast: http://railscasts.com/episodes/350-rest-api-versioning).

例如，有一个规范/请求规范:

For instance, there is a spec/requests spec:

require 'spec_helper'

describe "My Friends" do
  describe "GET /my/friends.json" do
    it "should get my_friends_path" do
      get v1_my_friends_path, {}, {'HTTP_ACCEPT' => 'application/vnd.myapp+json; level=1'}
      response.status.should be(401)
    end
  end
end

而且效果很好.但是(保持这个例子)我们如何编写路由规范?例如，此规范不正确:

And it works well. But (keeping this example) how can we write the routing spec? For instance this spec isn't correct:

require 'spec_helper'

describe "friends routing" do
  it "routes to #index" do
    get("/my/friends.json", nil, {'HTTP_ACCEPT' => 'application/vnd.myapp+json; level=1'}).
      should route_to({ action: "index",
                    controller: "api/v1/private/my/friends",
                        format: "json" })
  end
end

我尝试了不同的方式(例如request.headers['Accept'] 和@request.headers['Accept']，其中requestcode> 未定义且 @request 为零)；我真的不知道该怎么做.

I tried different ways (such as request.headers['Accept'] and @request.headers['Accept'], where request is undefined and @request is nil); I really don't see how to do.

我使用的是 Ruby 1.9.3、Rails 3.2.6 和 rspec-rails 2.11.0.谢谢.

I'm on Ruby 1.9.3, Rails 3.2.6 and rspec-rails 2.11.0. Thanks.

推荐答案

通过结合 Cristophe 和 Piotr 的答案中的想法，我想出了一个对我有用的解决方案.我使用的是 rspec 和 rails 3.0.

By combining the ideas from Cristophe's and Piotr's answers, I came up with a solution that worked for me. I'm using rspec and rails 3.0.

it 'should route like i want it to' do
  Rack::MockRequest::DEFAULT_ENV["HTTP_ACCEPT"] = "*/*"
  {get: "/foo/bar"}.
    should route_to(
    controller: 'foo',
    action: 'bar',
  )
  Rack::MockRequest::DEFAULT_ENV.delete "HTTP_ACCEPT"
end
