現在不少網站都要整合論壇程序，而康盛的Discuz系列產品每每是首選。而後就有了整合用戶的須要，康盛提供了Ucenter架構，方便對不一樣的應用程序進行單點登陸整合。 javascript

進來我嘗試將ucenter整合到Yii網站中，得到了成功，雖然登陸同步程序不是很穩當，基本使用沒有問題了。我將繼續改進。下面說說步驟： php

下載安裝ucenter和discuz，我使用的是ucenter1.6和discuz7.2，因爲7.2自帶的uc_client是舊版本，因此須要覆蓋一下1.6版本。
複製一份uc_client文件夾到 protected/vendors/下，而後創建一個ucenter.php文件，內容以下：
Php代碼
1. <?php
2. include dirname(__FILE__).'/../config/main.php';
3. include dirname(__FILE__).'/uc_client/client.php';
能夠看到這裏只是包含了兩個文件。而後打開yii的主配置文件 protected/config/main.php，加入ucenter的一些全局變量的設置：
Php代碼
1. <?php
2. define('UC_CONNECT', 'mysql'); // 鏈接 UCenter 的方式: mysql/NULL, 默認爲空時爲 fscoketopen()
3. // mysql 是直接鏈接的數據庫, 爲了效率, 建議採用 mysql
4. //數據庫相關 (mysql 鏈接時, 而且沒有設置 UC_DBLINK 時, 須要配置如下變量)
5. define('UC_DBHOST', 'localhost'); // UCenter 數據庫主機
6. define('UC_DBUSER', 'root'); // UCenter 數據庫用戶名
7. define('UC_DBPW', ''); // UCenter 數據庫密碼
8. define('UC_DBNAME', '027xfbbs'); // UCenter 數據庫名稱
9. define('UC_DBCHARSET', 'utf8'); // UCenter 數據庫字符集
10. define('UC_DBTABLEPRE', '027xfbbs.uc_'); // UCenter 數據庫表前綴
12. //通訊相關
13. define('UC_KEY', 'ebR4GhhpZB7e9Mhb'); // 與 UCenter 的通訊密鑰, 要與 UCenter 保持一致
14. define('UC_API', 'http://027xf.test/ucenter'); // UCenter 的 URL 地址, 在調用頭像時依賴此常量
15. define('UC_CHARSET', 'utf8'); // UCenter 的字符集
16. define('UC_IP', ''); // UCenter 的 IP, 當 UC_CONNECT 爲非 mysql 方式時, 而且當前應用服務器解析域名有問題時, 請設置此值
17. define('UC_APPID', 2); // 當前應用的 ID
19. // uncomment the following to define a path alias
20. // Yii::setPathOfAlias('local','path/to/local-folder');
22. // This is the main Web application configuration. Any writable
23. // CWebApplication properties can be configured here.
24. return array(
25. 'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
27. .....
請根據你的狀況修改上面的數據庫名等設置。
實現同步註冊，我採用的是定義了表單RegisterForm來處理用戶的註冊，下面是一個典型的註冊表單及其驗證和業務邏輯代碼：
Php代碼
1. <?php
3. /**
4. * LoginForm class.
5. * LoginForm is the data structure for keeping
6. * user login form data. It is used by the 'login' action of 'SiteController'.
7. */
8. class RegisterForm extends CFormModel
9. {
10. public $username;
11. public $password;
12. public $repassword;
13. public $email;
14. public $verifyCode;
16. /**
17. * Declares the validation rules.
18. * The rules state that username and password are required,
19. * and password needs to be authenticated.
20. */
21. public function rules()
22. {
23. return array(
24. // username and password are required
25. array('username, password, repassword, email, verifyCode', 'required'),
26. array('username', 'length', 'max'=>20, 'min'=>5),
27. // 用戶名惟一性驗證
28. //array('username', 'unique','caseSensitive'=>false,'className'=>'user','message'=>'用戶名"{value}"已經被註冊，請更換'),
29. array('username', 'checkname'),
30. // 密碼一致性驗證
31. array('repassword', 'compare', 'compareAttribute'=>'password','message'=>'兩處輸入的密碼並不一致'),
32. // 電子郵件驗證
33. array('email', 'email'),
34. // 電子郵件惟一性
35. //array('email', 'unique','caseSensitive'=>false,'className'=>'user','message'=>'電子郵件"{value}"已經被註冊，請更換'),
36. array('email', 'checkemail'),
37. //array('birthday', 'match', 'pattern'=& gt;'%^\d{4}(\-|\/|\.)\d{1,2}\1\d{1,2}$%', 'allowEmpty'=> true, 'message'=>'生日必須是年-月-日格式'),
38. //array('mobile', 'length', 'max'=>11, 'min'=>11, 'tooLong'=>'手機號碼錯誤','tooShort'=>'手機號碼錯誤'),
39. array('verifyCode', 'captcha', 'allowEmpty'=> false),
40. );
41. }
43. public function checkname($attribute,$params)
44. {
45. //ucenter
46. Yii::import('application.vendors.*');
47. include_once 'ucenter.php';
48. $flag = uc_user_checkname($this->username);
50. switch($flag)
51. {
52. case -1:
53. $this->addError('username', '用戶名不合法');
54. break;
55. case -2:
56. $this->addError('username','包含不容許註冊的詞語');
57. break;
58. case -3:
59. $this->addError('username','用戶名已經存在');
60. break;
61. }
62. }
64. public function checkemail($attribute,$params)
65. {
66. //ucenter
67. Yii::import('application.vendors.*');
68. include_once 'ucenter.php';
69. $flag = uc_user_checkemail($this->email);
71. switch($flag)
72. {
73. case -4:
74. $this->addError('email', 'Email 格式有誤');
75. break;
76. case -5:
77. $this->addError('email','Email 不容許註冊');
78. break;
79. case -6:
80. $this->addError('email','該 Email 已經被註冊');
81. break;
82. }
83. }
85. /**
86. * Declares attribute labels.
87. */
88. public function attributeLabels()
89. {
90. return array(
91. 'username'=>'設定用戶名',
92. 'password'=>'設定密碼',
93. 'repassword'=>'再次輸入密碼',
94. 'email'=>'電子郵件地址',
95. 'mobile'=>'手機號碼',
96. 'verifyCode'=>'驗證碼',
97. );
98. }
100. /**
101. * 註冊用戶
102. * @return boolean whether register is successful
103. */
104. public function register($uid)
105. {
106. //ucenter
107. Yii::import('application.vendors.*');
108. include_once 'ucenter.php';
109. $uid = uc_user_register($this->username, $this->password, $this->email);
110. if($uid>0)
111. {
112. $model = new user;
113. $model->attributes = $_POST['RegisterForm'];
114. $model->password = md5($_POST['RegisterForm']['password']);
115. $model->id = $uid;
117. return $model->save();
118. }
119. }
120. }
咱們看看上面的代碼，調用了uc_user_checkname和uc_user_checkemail完成了用戶名和email的驗證，而後調用了 uc_user_register將用戶註冊到ucenter，成功後，再註冊到Yii應用。
實現用戶登陸，典型的Yii應用使用 CUserIdentity來實現登陸，咱們要作的就是繼承它，實現本身的驗證邏輯：
Php代碼
1. <?php
3. /**
4. * UserIdentity represents the data needed to identity a user.
5. * It contains the authentication method that checks if the provided
6. * data can identity the user.
7. */
8. class UserIdentity extends CUserIdentity
9. {
10. public $id;
11. /**
12. * Authenticates a user.
13. * The example implementation makes sure if the username and password
14. * are both 'demo'.
15. * In practical applications, this should be changed to authenticate
16. * against some persistent user identity storage (e.g. database).
17. * @return boolean whether authentication succeeds.
18. */
19. public function authenticate()
20. {
21. //ucenter
22. Yii::import('application.vendors.*');
23. include_once 'ucenter.php';
24. list($uid, $username, $password, $email) = uc_user_login($this->username, $this->password);
25. if($uid > 0)
26. {
27. $user = user::model()->findByPk($uid);
29. if($user == null)//說明網站數據庫中沒有，而ucenter中有這個用戶，添加用戶
30. {
31. $user = new user;
32. $user->username = $username;
33. $user->password = md5($password);
34. $user->email = $email;
35. $user->id = $uid;
36. $user->save();
38. $user->refresh();
39. }
41. $this->username = $user->username;
42. $this->id = $user->id;
44. $user->last_login_time = $user->this_login_time;
45. $user->this_login_time = time();
46. $user->last_login_ip = $user->this_login_ip;
47. $user->this_login_ip = Yii::app()->getRequest()->userHostAddress;
48. $user->save();
50. $this->errorCode=self::ERROR_NONE;
51. }
52. elseif($uid == -1)
53. {
54. $this->errorCode=self::ERROR_USERNAME_INVALID;
55. }
56. elseif($uid == -2)
57. {
58. $this->errorCode=self::ERROR_PASSWORD_INVALID;
59. }
61. return !$this->errorCode;
62. }
64. public function getId()
65. {
66. return $this->id;
67. }
68. }
請根據本身的應用狀況進行修改便可，這裏咱們不須要對Yii的用戶登陸作任何修改。
而後咱們修改 SiteController/actionLogin 方法，將同步登陸其餘應用的js輸出到瀏覽器：
Php代碼
1. /**
2. * Displays the login page
3. */
4. public function actionLogin()
5. {
6. $model=new LoginForm;
8. // if it is ajax validation request
9. if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
10. {
11. echo CActiveForm::validate($model);
12. Yii::app()->end();
13. }
15. // collect user input data
16. if(isset($_POST['LoginForm']))
17. {
18. $model->attributes=$_POST['LoginForm'];
19. // validate user input and redirect to the previous page if valid
20. if($model->validate() && $model->login())
21. {
22. //ucenter
23. Yii::import('application.vendors.*');
24. include_once 'ucenter.php';
25. $script = uc_user_synlogin(Yii::app()->user->id);
26. $this->render('loginsuc', array(
27. 'script' => $script,
28. ));
29. Yii::app()->end();
30. }
31. }
32. // display the login form
33. $this->render('login',array('model'=>$model));
34. }
簡單的loginsuc.php視圖文件：
Php代碼
1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
2. <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
3. <head>
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5. </head>
6. <body>
7. <?php
8. $this->layout = 'none';
9. echo $script;
10. ?>
11. <script type="text/javascript">setTimeout('location.href="<?php echo Yii::app()->user->returnUrl ?>"',3000);</script>
12. 登陸成功，正在返回登陸前頁面...
13. </body>
14. </html>
繼續修改 SiteController/actionLogout方法，實現同步退出：
Php代碼
1. /**
2. * Logs out the current user and redirect to homepage.
3. */
4. public function actionLogout()
5. {
6. Yii::app()->user->logout();
7. //ucenter
8. Yii::import('application.vendors.*');
9. include_once 'ucenter.php';
10. $script = uc_user_synlogout();
11. $this->render('logoutsuc', array(
12. 'script' => $script,
13. ));
14. Yii::app()->end();
15. }
簡單的logoutsuc.php視圖文件：
Php代碼
1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
2. <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
3. <head>
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5. </head>
6. <body>
7. <?php
8. $this->layout = 'none';
9. echo $script;
10. ?>
11. <script type="text/javascript">setTimeout('location.href="<?php echo Yii::app()->homeUrl ?>"',3000);</script>
12. 退出成功，正在返回首頁...
13. </body>
14. </html>
進行到這裏，咱們已經實現了整合ucenter的登陸和註冊了，這樣ucenter中有的用戶，能夠登陸到yii應用，yii應用也能夠註冊用戶到ucenter了。可是這尚未完成，咱們須要的是在discuz中用戶登陸時，也同步登陸yii應用，退出亦然，那麼咱們須要實現 Yii應用的 api/uc.php 這個接口程序。因爲咱們要用到Yii的框架資源，因此我沒有采用硬編碼的方式實現這個接口，而是建立了一個UcApplication類完成這個任務，繼續往下看。
首先創建 api/uc.php 入口文件，代碼以下：
Php代碼
1. <?php
2. define('UC_CLIENT_VERSION', '1.6.0');
3. define('UC_CLIENT_RELEASE', '20110501');
5. define('API_DELETEUSER', 1); //note 用戶刪除 API 接口開關
6. define('API_RENAMEUSER', 1); //note 用戶更名 API 接口開關
7. define('API_GETTAG', 1); //note 獲取標籤 API 接口開關
8. define('API_SYNLOGIN', 1); //note 同步登陸 API 接口開關
9. define('API_SYNLOGOUT', 1); //note 同步登出 API 接口開關
10. define('API_UPDATEPW', 1); //note 更改用戶密碼開關
11. define('API_UPDATEBADWORDS', 1); //note 更新關鍵字列表開關
12. define('API_UPDATEHOSTS', 1); //note 更新域名解析緩存開關
13. define('API_UPDATEAPPS', 1); //note 更新應用列表開關
14. define('API_UPDATECLIENT', 1); //note 更新客戶端緩存開關
15. define('API_UPDATECREDIT', 1); //note 更新用戶積分開關
16. define('API_GETCREDITSETTINGS', 1); //note 向 UCenter 提供積分設置開關
17. define('API_GETCREDIT', 1); //note 獲取用戶的某項積分開關
18. define('API_UPDATECREDITSETTINGS', 1); //note 更新應用積分設置開關
20. define('API_RETURN_SUCCEED', '1');
21. define('API_RETURN_FAILED', '-1');
22. define('API_RETURN_FORBIDDEN', '-2');
24. // change the following paths if necessary
25. $yii=dirname(__FILE__).'/../protected/yii-1.1.6/framework/yii.php';
26. $config=dirname(__FILE__).'/../protected/config/main.php';
28. // remove the following lines when in production mode
29. defined('YII_DEBUG') or define('YII_DEBUG',true);
30. // specify how many levels of call stack should be shown in each log message
31. defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',0);
33. require_once($yii);
34. require(dirname(__FILE__).'/../protected/components/UcApplication.php');
35. Yii::createApplication('UcApplication', $config)->run();
這裏能夠看到，這個腳本和標準的index.php是同樣的，只是使用了不一樣的Application類。咱們接着看這個類。
創建 protected/components/UcApplication.php類文件：
Php代碼
1. <?php
2. class UcApplication extends CWebApplication
3. {
4. public $defaultController = 'Uc';
6. private $route = '';
8. protected function preinit()
9. {
10. $this->parseRequest();
11. }
13. private function parseRequest()
14. {
15. $_DCACHE = $get = $post = array();
17. $code = @$_GET['code'];
18. parse_str($this->_authcode($code, 'DECODE', UC_KEY), $get);
19. if(MAGIC_QUOTES_GPC) {
20. $get = $this->_stripslashes($get);
21. }
23. $timestamp = time();
24. if($timestamp - $get['time'] > 3600) {
25. //exit('Authracation has expiried');
26. }
27. if(emptyempty($get)) {
28. exit('Invalid Request');
29. }
30. $action = $get['action'];
32. require_once 'xml.class.php';
33. $post = xml_unserialize(file_get_contents('php://input'));
34. Yii::log($get, 'debug');
35. Yii::log($post, 'debug');
36. $_GET = $get;
37. $_POST = $post;
39. $this->route = $this->defaultController .'/'. $action;
41. if(!in_array($action, array('test', 'deleteuser', 'renameuser', 'gettag', 'synlogin', 'synlogout', 'updatepw', 'updatebadwords', 'updatehosts', 'updateapps', 'updateclient', 'updatecredit', 'getcreditsettings', 'updatecreditsettings')))
42. {
43. exit(API_RETURN_FAILED);
44. }
45. }
47. public function processRequest()
48. {
49. $this->runController($this->route);
50. }
52. private function _authcode($string, $operation = 'DECODE', $key = '', $expiry = 0) {
53. $ckey_length = 4;
55. $key = md5($key ? $key : UC_KEY);
56. $keya = md5(substr($key, 0, 16));
57. $keyb = md5(substr($key, 16, 16));
58. $keyc = $ckey_length ? ($operation == 'DECODE' ? substr($string, 0, $ckey_length): substr(md5(microtime()), -$ckey_length)) : '';
60. $cryptkey = $keya.md5($keya.$keyc);
61. $key_length = strlen($cryptkey);
63. $string = $operation == 'DECODE' ? base64_decode(substr($string, $ckey_length)) : sprintf('%010d', $expiry ? $expiry + time() : 0).substr(md5($string.$keyb), 0, 16).$string;
64. $string_length = strlen($string);
66. $result = '';
67. $box = range(0, 255);
69. $rndkey = array();
70. for($i = 0; $i <= 255; $i++) {
71. $rndkey[$i] = ord($cryptkey[$i % $key_length]);
72. }
74. for($j = $i = 0; $i < 256; $i++) {
75. $j = ($j + $box[$i] + $rndkey[$i]) % 256;
76. $tmp = $box[$i];
77. $box[$i] = $box[$j];
78. $box[$j] = $tmp;
79. }
81. for($a = $j = $i = 0; $i < $string_length; $i++) {
82. $a = ($a + 1) % 256;
83. $j = ($j + $box[$a]) % 256;
84. $tmp = $box[$a];
85. $box[$a] = $box[$j];
86. $box[$j] = $tmp;
87. $result .= chr(ord($string[$i]) ^ ($box[($box[$a] + $box[$j]) % 256]));
88. }
90. if($operation == 'DECODE') {
91. if((substr($result, 0, 10) == 0 || substr($result, 0, 10) - time() > 0) && substr($result, 10, 16) == substr(md5(substr($result, 26).$keyb), 0, 16)) {
92. return substr($result, 26);
93. } else {
94. return '';
95. }
96. } else {
97. return $keyc.str_replace('=', '', base64_encode($result));
98. }
100. }
102. private function _stripslashes($string) {
103. if(is_array($string)) {
104. foreach($string as $key => $val) {
105. $string[$key] = $this->_stripslashes($val);
106. }
107. } else {
108. $string = stripslashes($string);
109. }
110. return $string;
111. }
112. }
這裏能夠看到，主要邏輯是processRequest方法，實現了ucenter通知的解碼、調用相應的控制器和動做實現操做。
而後創建 protected/controller/UcController.php文件，代碼以下：
Php代碼
1. <?php
2. class UcController extends Controller
3. {
4. private $appdir = '';
6. protected function beforeAction(CAction $action)
7. {
8. $this->appdir = Yii::app()->basePath . '/vendors/';
9. return parent::beforeAction($action);
10. }
12. public function actionTest() {
13. echo API_RETURN_SUCCEED;
14. }
16. public function actionDeleteuser() {
17. $uids = explode(',', str_replace("'", '', $_GET['ids']));
18. !API_DELETEUSER && exit(API_RETURN_FORBIDDEN);
20. $users = user::model()->findAllByPk($uids);
21. foreach($users as $user)
22. {
23. $user->delete();
24. }
26. echo API_RETURN_SUCCEED;
27. }
29. public function actionRenameuser() {
30. $uid = $_GET['uid'];
31. $usernameold = $_GET['oldusername'];
32. $usernamenew = $_GET['newusername'];
33. if(!API_RENAMEUSER) {
34. echo API_RETURN_FORBIDDEN;
35. }
37. $user = user::model()->findByPk($uid);
38. if($user !== null)
39. {
40. $user->username = $usernamenew;
41. if($user->save(false))
42. echo API_RETURN_SUCCEED;
43. else
44. echo API_RETURN_FAILED;
45. }
46. }
48. public function actionGettag() {
49. $name = $_GET['id'];
50. if(!API_GETTAG) {
51. echo API_RETURN_FORBIDDEN;
52. }
54. $echo = array();
55. echo $this->_serialize($return, 1);
56. }
58. public function actionSynlogin() {
59. $uid = $_GET['uid'];
60. $username = $_GET['username'];
61. if(!API_SYNLOGIN) {
62. echo API_RETURN_FORBIDDEN;
63. }
65. $identity=new UcUserIdentity($username);
67. if($identity->authenticate())
68. {
69. Yii::app()->user->login($identity, 0);
70. }
72. header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');
73. //$_SESSION[Yii::app()->user->stateKeyPrefix.'__id'] = $uid;
74. //$_SESSION[Yii::app()->user->stateKeyPrefix.'__name'] = $username;
75. }
77. public function actionSynlogout() {
78. if(!API_SYNLOGOUT) {
79. echo API_RETURN_FORBIDDEN;
80. }
82. //note 同步登出 API 接口
83. header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');
84. Yii::app()->user->logout();
85. }
87. public function actionUpdatepw() {
88. if(!API_UPDATEPW) {
89. echo API_RETURN_FORBIDDEN;
90. }
91. $username = $_GET['username'];
92. $password = $_GET['password'];
94. $user = user::model()->findByAttributes(array('username'=>$username));
95. if($user !== null)
96. {
97. $user->password = md5($password);
98. if($user->save())
99. echo API_RETURN_SUCCEED;
100. else
101. echo API_RETURN_FAILED;
102. }
103. else

105. }
107. public function actionUpdatebadwords() {
108. if(!API_UPDATEBADWORDS) {

上面用到了xml.class.php這個類文件，能夠在uc_client/lib目錄找到。
這裏須要說明的是，actionSynlogin方法中，利用了我定義的特殊的UserIdentity來登陸的，由於不須要提供密碼。
再來看看最後一個類：
Php代碼
1. <?php
3. /**
4. * UserIdentity represents the data needed to identity a user.
5. * It contains the authentication method that checks if the provided
6. * data can identity the user.
7. */
8. class UcUserIdentity extends CUserIdentity
9. {
10. public $id;
12. /**
13. * Constructor.
14. * @param string $username username
15. */
16. public function __construct($username)
17. {
18. $this->username=$username;
19. $this->password='';
20. }
21. /**
22. * Authenticates a user.
23. * The example implementation makes sure if the username and password
24. * are both 'demo'.
25. * In practical applications, this should be changed to authenticate
26. * against some persistent user identity storage (e.g. database).
27. * @return boolean whether authentication succeeds.
28. */
29. public function authenticate()
30. {
31. $user = user::model()->findByAttributes(array('username'=>$this->username));
33. if($user == null)//說明網站數據庫中沒有，而ucenter中有這個用戶，添加用戶
34. {
35. //ucenter
36. Yii::import('application.vendors.*');
37. include_once 'ucenter.php';
38. list($uid, $username, $email) = uc_get_user($this->username);
39. if($uid)
40. {
41. $user = new user;
42. $user->username = $username;
43. $user->password = md5(rand(10000,99999));
44. $user->email = $email;
45. $user->id = $uid;
46. $user->save();
48. $user->refresh();
49. }
50. }
52. $this->id = $user->id;
54. $user->last_login_time = $user->this_login_time;
55. $user->this_login_time = time();
56. $user->last_login_ip = $user->this_login_ip;
57. $user->this_login_ip = Yii::app()->getRequest()->userHostAddress;
58. $user->save();
60. $this->errorCode=self::ERROR_NONE;
62. return !$this->errorCode;
63. }
65. public function getId()
66. {
67. return $this->id;
68. }
69. }
能夠看到，在這個認證類中，實現了對yii應用中沒有的用戶的創建操做。而後不須要對yii應用作任何特殊設置，就能夠實現api接口了。
而後咱們在ucenter中添加yii應用的設置，修改main.php中的相應設置，應該就能夠實現ucenter的同步登陸、註冊、退出、刪除用戶、修改用戶名等等功能了！這個實現方法相對很Yii，呵呵。
