Yii 的 OpenId 支持 [英] OpenId support for Yii

问题描述

我想在 Yii 中使用 OpenID 支持.

I want to play with OpenID support in Yii.

在研究了可能的插件后，我找到了这两个.一个用于 OpenidSelector，一个用于 LightOpenId

After researching for possible plugins, I found these two. One for OpenidSelector and one for LightOpenId

http://www.yiiframework.com/extension/simpleopenidselector/

http://www.yiiframework.com/extension/loid

这些是在 Yii 中用于 OpenId 支持的正确扩展吗?还要别的吗?如果这些扩展是正确的，我想就如何处理这些扩展获得一些指导.

Are these the right extensions to use in Yii for OpenId support? Anything else? And I would like to get some guide line on what to do with these extensions if they are correct.

这是我认为除了按照页面上的说明安装它们之外我还需要做的事情.

This is what I think I need to do beside installing them as per instructions on the page.

1. 创建 OpenIdUserIdentity 扩展 CUserIdentity 并将 authenticate() 代码放在那里
2. 创建一个登录页面并将 simpleopenidselector 代码放入视图中.
3. 在 siteController 中创建 actionOpenIdLogin 方法

然后我有点迷茫，因为我不理解 Loid 中的用法示例，我不知道如何做上面的 (1) 和 (3).

then I am kind of lost as I don't understand the Usage sample in Loid and I am not sure how to do (1) and (3) above.

请让我知道我是否在正确的轨道上，并可能提供一些指导.谢谢.

Please let me know if I am on the right track and possibly provide some guidance. Thanks.

推荐答案

玩了一会儿，我来回答我自己的问题.这就是我使其工作的方式，因此您可以根据需要进行更改.

After playing with it for awhile, I am going to answer my own question. This is how I make it to work, so you can change it according to your needs.

注意:我使用 userController 而不是 siteController，请按照相应扩展页面中的所有说明进行操作.

Note: I use a userController instead of the siteController and please follow all the instructions in the respective extension page.

如果你使用了上面提到的两个插件，那么接下来你需要做的事情如下:(这是一个分步指南)但最重要的步骤是 2c 和 3，它们是两个插件的粘合剂

If you used the two plugins as indicated above, then what you need to do next to make it work are the followings: (this is a step by step guide) But the most important steps are 2c and 3, they are the glue to both plugins

1) 有一个使用 OpenidSelector 的登录页面.把它放在 views/user/login.php

1) Have a login page that uses the OpenidSelector. Place it at views/user/login.php

<?php
$this->widget('application.extensions.openidProviders.openidProviders', 
array ( 'options' => array ( 'lang' => 'en', 
//      'demo' => 'js:true',
    'cookie_expires' => 6*30,
    )));?>

2) 设置操作来处理来自 openidSelector 的选择.我把它放在 userController 中.

2) Setup actions to handle the selection from the openidSelector. I put this in the userController.

a) 在主配置文件中.

a) In main config file.

 'components'=>array(
    'user'=>array(
        // enable cookie-based authentication
        'allowAutoLogin'=>true,
        'loginUrl' => array('/user/login'), //change the default login page
    ),

b) 在 userController 文件中，添加登录和验证操作

b) In userController file, add login and authenticate actions

array('allow',  // allow all users to perform 'index' and 'view' actions
  'actions'=>array('login', 'authenticate'),

动作代码#1 actionLogin - 这是触发登录视图页面.

Code for action #1 actionLogin - this is to trigger the login view page.

public function actionLogin()
{       
    // display the login form
    $this->render('login',array());
}

c) 操作 #2 actionAuthenticate 的代码 - 从 LOID 指令页面修改的代码，这是在登录页面中选择 OpenIDProvider 时处理的.

c) Code for action #2 actionAuthenticate - code modified from the LOID instruction page, this is to handle when an OpenIDProvider is selected in the login page.

public function actionAuthenticate ()
{
   // Put the Simple usage: code on 
   // http://www.yiiframework.com/extension/loid here:

   // Code from loid Simple usage page.
   // START HERE
   $loid = Yii::app()->loid->load();
   if (!empty($_GET['openid_mode'])) {
       if ($_GET['openid_mode'] == 'cancel') {
         $err = Yii::t('core', 'Authorization cancelled');
       } else {
         try {
             echo $loid->validate() ? 'Logged in.' : 'Failed';
       } catch (Exception $e) {
             $err = Yii::t('core', $e->getMessage());
       }
   }
   if(!empty($err)) echo $err;
   } else {
       // **NOTE:Comment out this line from the loid sample page**
       // $loid->identity = "http://my.openid.identifier"; //Setting identifier
       // this openid_identifier is need after you click the openselector
       $loid->identity = $_GET['openid_identifier']; // CHANGE HERE

       $loid->required = array('namePerson/friendly', 'contact/email'); //Try to get info from openid provider
       $loid->realm     = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST']; 
       $loid->returnUrl = $loid->realm . $_SERVER['REQUEST_URI']; //getting return URL
       if (empty($err)) {
           try {
               $url = $loid->authUrl();
               $this->redirect($url);
           } catch (Exception $e) {
               $err = Yii::t('core', $e->getMessage());
           }
        }
    }
    // Code from loid Simple usage page.
    // END HERE
}

3) 将 openidProviders/views/main-en.php 中的 action URL 改为 Authenticate

3) Change the action URL to Authenticate in the openidProviders/views/main-en.php

改变

form action="examples/consumer/try_auth.php" method="get" id="openid_form"

到

form action="authenticate" method="get" id="openid_form"

应该是这样.没有测试失败案例，只测试了谷歌登录.

That should be it. Haven't tested failure case, only tested with google login.
