[英]How to use omniauth-google-oauth2 gem with incremental authorization in Rails?
[英]How can I write a Rails 4 test for creating a session with the omniauth-google-oauth2 gem?
我正在嘗試使用omniauth-google-oauth2
gem創建一個測試。 我是否需要使用post :create
傳遞env["omniauth.auth"]
變量? 也許當我試圖這樣做時,我做錯了。 我得到的錯誤如下所示......
耙測試錯誤
1) Error:
SessionsControllerTest#test_should_get_create:
NoMethodError: undefined method `provider' for nil:NilClass
app/models/user.rb:6:in `from_omniauth'
app/controllers/sessions_controller.rb:4:in `create'
test/controllers/sessions_controller_test.rb:13:in `block in <class:SessionsControllerTest>'
以下是我嘗試編寫測試...
SessionsControllerTest
require 'test_helper'
class SessionsControllerTest < ActionController::TestCase
setup :prepare_omniauth
test "should get create" do
post :create
redirect_to root_path, notice: "Signed in!"
end
test "should get destroy" do
get :destroy
assert session[:user_id].blank?, "user_id should no longer exist"
assert_redirected_to root_path, notice: "Signed out!"
end
private
def prepare_omniauth
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:google] = OmniAuth::AuthHash.new({
:provider => 'google',
:uid => '123545'
})
request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:google]
end
end
會話控制器
class SessionsController < ApplicationController
def create
user = User.from_omniauth(env["omniauth.auth"])
session[:user_id] = user.id
redirect_to root_path
end
def destroy
session[:user_id] = nil unless session[:user_id].blank?
redirect_to root_path
end
end
用戶模型
class User < ActiveRecord::Base
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_initialize.tap do |user|
user.provider = auth.provider
user.uid = auth.uid
user.name = auth.info.name
user.oauth_token = auth.credentials.token
user.oauth_expires_at = Time.at(auth.credentials.expires_at)
user.save!
end
end
end
我相信這個博客可以回答你的問題: http : //natashatherobot.com/rails-test-omniauth-sessions-controller/
基本上,您需要編輯rails_helper / spec_helper以將Omniauth的測試模式設置為true,並創建一個omniauth_hash以在測試中使用:
OmniAuth.config.test_mode = true
omniauth_hash = { 'provider' => 'github',
'uid' => '12345',
'info' => {
'name' => 'natasha',
'email' => 'hi@natashatherobot.com',
'nickname' => 'NatashaTheRobot'
},
'extra' => {'raw_info' =>
{ 'location' => 'San Francisco',
'gravatar_id' => '123456789'
}
}
}
OmniAuth.config.add_mock(:github, omniauth_hash)
然后在任何測試之前你需要它:
before do
request.env['omniauth.auth'] = OmniAuth.config.mock_auth[:github]
end
現在您應該能夠使用Omniauth創建用戶,如下例所示:
describe SessionsController do
it "should successfully create a user" do
expect {
post :create, provider: :github
}.to change{ User.count }.by(1)
end
end
