我正在开发一个rails项目,我在其中使用CanCan来授权我的资源。当用户未登录并尝试提交“谈话”(通过ajax表单提交)时,CanCan会正确引发401 {"status":"error","message":"You must be logged in to do that!"}
作为响应(我已在浏览器中使用firebug验证了这一点)。但是,在我的测试中得到302响应代码而不是401:
class TalksController < ApplicationController
authorize_resource
def create
@talk = current_user.talks.build(params[:talk])
respond_to do |format|
if @talk.save
response = { :redirect => talk_path(@talk) }
format.html { redirect_to @talk, notice: 'Talk was successfully created.' }
format.json { render json: response, status: :created, }
else
format.html { render action: "new" }
format.json { render json: @talk.errors, status: :unprocessable_entity }
end
end
end
end
talks_controller_spec.rb:
describe TalksController do
describe "POST create" do
context "when not signed in" do
it "should not assign talk" do
post :create
assigns[:talk].should be_nil
end
it "should respond with a 401" do
post :create
response.response_code.should == 401
end
end
end
end
此处包含的第一个示例是成功的(分配[:talk]未分配),但第二个不是:
1) TalksController POST create when not signed in should respond with a 401
Failure/Error: response.response_code.should == 401
expected: 401
got: 302 (using ==)
# ./spec/controllers/talks_controller_spec.rb:53:in `block (4 levels) in <top (required)>'
我不确定到底发生了什么。有没有办法可以测试返回给浏览器的实际响应代码?或者我可以更好地测试授权?
答案 0 :(得分:8)
事实证明,我的项目使用以下功能从CanCan中拯救了授权例外。因为当请求是ajax时函数只引发401(否则重定向),我在浏览器中得到401,但不是我的测试。
# Handle authorization exceptions
rescue_from CanCan::AccessDenied do |exception|
if request.xhr?
if signed_in?
render json: {:status => :error, :message => "You don't have permission to #{exception.action} #{exception.subject.class.to_s.pluralize}"}, :status => 403
else
render json: {:status => :error, :message => "You must be logged in to do that!"}, :status => 401
end
else
render :file => "public/401.html", :status => :unauthorized
end
end
感谢zetetic建议我检查我的测试日志,因为这显示了请求的不同。
