我已经在网上搜索过了,但是,我似乎就是不能让Rspec正确地发送内容类型,这样我就可以测试我的JSON API了。我将RABL gem用于模板、Rails 3.0.11和Ruby 1.9.2-p180。
我的curl输出,工作正常(我知道应该是401 ):
mrsnuggles:tmp gaahrdner$ curl -i -H "Accept: application/json" -X POST -d @bleh http://localhost:3000/applications
HTTP/1.1 403 Forbidden
Content-Type: application/json; charset=utf-8
Cache-Control: no-cache
X-Ua-Compatible: IE=Edge
X-Runtime: 0.561638

Set-Cookie: _session_id=8e8b73b5a6e5c95447aab13dafd59993; path=/; HttpOnly
{"status":"error","message":"You are not authorized to access this page."}
来自我的一个测试用例的示例:
describe ApplicationsController do
render_views
disconnect_sunspot
let(:application) { Factory.create(:application) }
subject { application }
context "JSON" do
describe "creating a new application" do
context "when not authorized" do
before do
json = { :application => { :name => "foo", :description => "bar" } }
request.env['CONTENT_TYPE'] = 'application/json'
request.env['RAW_POST_DATA'] = json
post :create
end
it "should not allow creation of an application" do
Application.count.should == 0
end
it "should respond with a 403" do
response.status.should eq(403)
end
it "should have a status and message key in the hash" do
JSON.parse(response.body)["status"] == "error"
JSON.parse(response.body)["message"] =~ /authorized/
end
end
context "authorized" do
end
end
end
end
这些测试永远不会通过,我总是被重定向,并且我的内容类型总是text/html
,不管我如何在我的before代码块中指定类型:
# nope
before do
post :create, {}, { :format => :json }
end
# nada
before do
post :create, :format => Mime::JSON
end
# nuh uh
before do
request.env['ACCEPT'] = 'application/json'
post :create, { :foo => :bar }
end
下面是rspec的输出:
Failures:
1) ApplicationsController JSON creating a new application when not authorized should respond with a 403
Failure/Error: response.status.should eq(403)
expected 403
got 302
(compared using ==)
# ./spec/controllers/applications_controller_spec.rb:31:in `block (5 levels) in <top (required)>'
2) ApplicationsController JSON creating a new application when not authorized should have a status and message key in the hash
Failure/Error: JSON.parse(response.body)["status"] == "errors"
JSON::ParserError:
756: unexpected token at '<html><body>You are being <a href="http://test.host/">redirected</a>.</body></html>'
# ./spec/controllers/applications_controller_spec.rb:35:in `block (5 levels) in <top (required)>'
正如你所看到的,我得到了HTML格式的302重定向,即使我试图指定'application/json‘。
下面是我的application_controller.rb
,带有rescue_from代码:
class ApplicationController < ActionController::Base
rescue_from ActiveRecord::RecordNotFound, :with => :not_found
protect_from_forgery
helper_method :current_user
helper_method :remove_dns_record
rescue_from CanCan::AccessDenied do |exception|
flash[:alert] = exception.message
respond_to do |format|
h = { :status => "error", :message => exception.message }
format.html { redirect_to root_url }
format.json { render :json => h, :status => :forbidden }
format.xml { render :xml => h, :status => :forbidden }
end
end
private
def not_found(exception)
respond_to do |format|
h = { :status => "error", :message => exception.message }
format.html { render :file => "#{RAILS_ROOT}/public/404.html", :status => :not_found }
format.json { render :json => h, :status => :not_found }
format.xml { render :xml => h, :status => :not_found }
end
end
end
还有applications_controller.rb
,特别是“create”操作,这也是我要测试的。目前它相当难看,因为我使用了state_machine
并覆盖了delete方法。
def create
# this needs to be cleaned up and use accepts_attributes_for
@application = Application.new(params[:application])
@environments = params[:application][:environment_ids]
@application.environment_ids<<@environments unless @environments.blank?
if params[:site_bindings] == "new"
@site = Site.new(:name => params[:application][:name])
@environments.each do |e|
@site.siteenvs << Siteenv.new(:environment_id => e)
end
end
if @site
@application.sites << @site
end
if @application.save
if @site
@site.siteenvs.each do |se|
appenv = @application.appenvs.select {|e| e.environment_id == se.environment_id }
se.appenv = appenv.first
se.save
end
end
flash[:success] = "New application created."
respond_with(@application, :location => @application)
else
render 'new'
end
# super stinky :(
@application.change_servers_on_appenvs(params[:servers]) unless params[:servers].blank?
@application.save
end
我已经查看了这里的源代码:https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/responder.rb,它似乎应该正确响应,以及一些关于堆栈溢出的问题,这些问题似乎有类似的问题和可能的解决方案,但都不适合我。
我做错了什么?

尝试将:format
密钥移动到请求的参数散列中,如下所示:
describe ApplicationsController do
render_views
disconnect_sunspot
let(:application) { Factory.create(:application) }
subject { application }
context "JSON" do
describe "creating a new application" do
context "when not authorized" do
it "should not allow creation of an application" do
params = { :format => 'json', :application => { :name => "foo", :description => "bar" } }
post :create, params
Expect(Application.count).to eq(0)
expect(response.status).to eq(403)
expect(JSON.parse(response.body)["status"]).to eq("error")
expect(JSON.parse(response.body)["message"]).to match(/authorized/)
end
end
context "authorized" do
end
end
end
end
让我知道它进行得怎么样!这就是我设置测试的方式,它们工作得很好!

我意识到设置:format => :json
是一种解决方案(如上所述)。但是,我想测试与我的API的客户端使用的条件相同的条件。我的客户机不会设置:format
参数,而是设置Accept
HTTP头。如果您对此解决方案感兴趣,以下是我使用的解决方案:
# api/v1/test_controller_spec.rb
require 'spec_helper.rb'
describe Api::V1::TestController do
render_views
context "when request sets accept => application/json" do
it "should return successful response" do
request.accept = "application/json"
get :test
response.should be_success
end
end
end
