Laravel5中集成Jasig cas统一认证系统 - mrhyher
环境:Linux(ubuntu)
一,下载phpcas源代码。
在laravel5的项目app目录下创建library目录,下载phpcas库,git clone https://github.com/Jasig/phpCAS.git,clone下来是一个phpcas的文件目录。
二,创建provider
在app下创建目录cas,创建CasAuthProvider.php,内容如下:
1 php 2 3 namespace cas; 4 5 use Illuminate\Contracts\Auth\UserProvider; 6 use Illuminate\Contracts\Hashing\Hasher; 7 use Illuminate\Contracts\Auth\Authenticatable; 8 use Illuminate\Auth\GenericUser; 9 10 class CasAuthProvider implements UserProvider { 11 12 /** 13 * Retrieve a user by their unique identifier. 14 * 15 * @param mixed $id 16 * @return \Illuminate\Auth\UserInterface|null 17 */ 18 public function retrieveById($id) { 19 return $this->casUser(); 20 } 21 22 /** 23 * Retrieve a user by the given credentials. 24 * 25 * @param array $credentials 26 * @return \Illuminate\Auth\UserInterface|null 27 */ 28 public function retrieveByCredentials(array $credentials) { 29 return $this->casUser(); 30 } 31 32 /** 33 * Validate a user against the given credentials. 34 * 35 * @param \Illuminate\Auth\UserInterface $user 36 * @param array $credentials 37 * @return bool 38 */ 39 public function validateCredentials(Authenticatable $user, array $credentials) { 40 return true; 41 } 42 43 protected function casUser() { 44 $cas_host = \Config::get('app.cas_host'); 45 //dump($cas_host); 46 $cas_context = \Config::get('app.cas_context'); 47 $cas_port = \Config::get('app.cas_port'); 48 \phpCAS::setDebug(); 49 \phpCAS::client(CAS_VERSION_2_0, $cas_host, $cas_port, $cas_context); 50 \phpCAS::setNoCasServerValidation(); 51 52 if (\phpCAS::isAuthenticated()) { 53 $attributes = array( 54 'id' => \phpCAS::getUser(), 55 'name' => \phpCAS::getUser() 56 ); 57 return new GenericUser($attributes); 58 } else { 59 //\phpCAS::setServerURL(\Config::get('app.url')); 60 \phpCAS::forceAuthentication(); 61 } 62 return null; 63 } 64 65 /** 66 * Needed by Laravel 4.1.26 and above 67 */ 68 public function retrieveByToken($identifier, $token) { 69 return new \Exception('not implemented'); 70 } 71 72 /** 73 * Needed by Laravel 4.1.26 and above 74 */ 75 public function updateRememberToken(Authenticatable $user, $token) { 76 return new \Exception('not implemented'); 77 } 78 79 } 80 81 ?>
三,修改config
在config/app.php中添加如下三个配置项:
'cas_host'=>'****', //认证服务器
'cas_context'=>'',//还没弄明白是什么
'cas_port'=>000,//认证服务端口
'url'=>'http://localhost/',
四,加载认证库
在app/providers/AppServiceProvider.php里,在类AppServiceProvider的register函数里添加认证方式:
Auth::extend('cas', function($app) {
return new CasAuthProvider;
});
修改app/config/auth.php认证driver:'driver' => 'cas',
在composer.json里配置加载项,在autoload里的classmap中添加如下路径:
"autoload": {
"classmap": [
**************
"app/library",
"app/library/phpCAS",
"app/cas"
]
}
在项目根目录下执行:composer dump-autoload
五,实现
在app/http/controllers/下创建CasAuthController.php,添加login和logout方法:
1 public function login() { 2 3 $message_error = ""; 4 if (Auth::check()) { 5 6 } else { 7 if (Auth::attempt(array())) { 8 // Redirect to link after login 9 } 10 // Redirect to un-logged in page 11 } 12 dump(\phpCAS::getUser()); 13 dump(Auth::user()); 14 } 15 16 public function logout() { 17 18 $cas_host = \Config::get('app.cas_host'); 19 //dump($cas_host); 20 $cas_context = \Config::get('app.cas_context'); 21 $cas_port = \Config::get('app.cas_port'); 22 \phpCAS::setDebug(); 23 \phpCAS::client(CAS_VERSION_2_0, $cas_host, $cas_port, $cas_context); 24 \phpCAS::setNoCasServerValidation(); 25 \phpCAS::logoutWithRedirectService(\Config::get('app.url')); 26 }
在routes.php里添加路由规则就OK了,把项目默认的登陆和注销方法指到这里来,当login的时候,会出现服务器的登陆页面。
有个问题,就是这么改动之后,原来我设置的不需要登陆就能浏览的页面,现在进入的时候也会跳出登陆页面,不知道为什么,希望高手指导下,谢谢!
