怎样在你的 ruby on rails 网站中加入 OpenID 登录功能
my OS is ubuntu7.10:1.cd to the project directory
2.sudo gem install ruby-openid
3.sudo ruby script/plugin install open_id_authentication
4.rake -T open_id (to see the rake command)
5.rake open_id_authentication:db:create
6.in the open-id migrate add these lines:
add_column :users, :identity_url, :string (in self.up)
remove_column :users, :identity_url (in self.down)
7.run the migrate
8.add a line in routes.rb:
map.open_id_complete 'session', :controller => "session", :action => "create",:requirements => { :method => :get }
VERY VERY IMPORTENT!!!
make sure the map.open_id_complete line above the map.resource :session line;(IT waste lots of my time!!!)
9:add a :identity_url in user.rb and it will look like:
attr_accessible :login, :email, :password, :password_confirmation, :identity_url
10.add some line in session/new.rhtml:
<p> <label for="openid_url">OpenID URL</label><br/> <%=text_field_tag "openid_url"%></p>
11.:
# This controller handles the login/logout function of the site.
class SessionController < ApplicationController# Be sure to include AuthenticationSystem in Application Controller instead# include AuthenticatedSystem# render new.rhtmllayout "welcome" def newenddef create if using_open_id? open_id_authentication(params[:openid_url]) else password_authentication(params[:login], params[:password]) endend def destroy self.current_user.forget_me if logged_in? cookies.delete :auth_token reset_session flash[:notice] = "你已经登录了." redirect_back_or_default('/')end protected def open_id_authentication(openid_url) authenticate_with_open_id(openid_url, :required => [:nickname, :email]) do |result, identity_url, registration| if result.successful? @user = User.find_or_initialize_by_identity_url(identity_url) if @user.new_record? @user.login = registration['nickname'] @user.email = registration['email'] @user.save(false) end self.current_user = @user successful_login else failed_login result.message end endend def password_authentication(login, password) self.current_user = User.authenticate(login, password) if logged_in? successful_login else failed_login endend def failed_login(message = "Authentication failed.") flash.now[:error] = message render :action => 'new'enddef successful_login if params[:remember_me] == "1" self.current_user.remember_me cookies[:auth_token] = { :value => self.current_user.remember_token , :expires => self.current_user.remember_token_expires_at } end redirect_back_or_default('/tools') flash[:notice] = "登录成功"endend
12.add some css:
/* embeds the openid image in the text field */input#openid_url { background: url(http://openid.net/login-bg.gif) no-repeat; background-color: #fff; background-position: 0 50%; color: #000; padding-left: 18px;}
